Fix Uniswap V4 Universal Router swap function with hardcoded Base mainnet deployment

[Copilot]

Fix Uniswap V4 Universal Router swap function using V4Planner pattern

• Create EtherTrialsPointBased_v6.sol with broken V4 swap implementation
• Understand Uniswap Universal Router v2 command structure
• Implement official V4Planner pattern with encoded V4 actions
• Use single V4_SWAP command with SWAP_EXACT_IN_SINGLE, SETTLE_ALL, TAKE_ALL actions
• Improve parameter encoding to exactly match SDK pattern
• Enhanced documentation with SDK references
• Fix stack too deep compiler error in getUserInfo function
• Fix compiler warning about shadowing builtin symbol
• Hardcode Base mainnet deployment parameters (zero constructor arguments required)
• Test compilation (compiles successfully with zero warnings/errors)

Final Implementation:

The contract now properly implements the Uniswap V4 SDK pattern for single-hop swaps:

V4 Action Flow:

1. SWAP_EXACT_IN_SINGLE (0x00): Executes exact input single-hop swap
   • Parameters: poolKey, zeroForOne, amountIn, amountOutMinimum, hookData
2. SETTLE_ALL (0x09): Settles all input currency (WETH)
   • Parameters: currency, amount
3. TAKE_ALL (0x0a): Takes all output currency (TRIA)
   • Parameters: currency, amountMin

Encoding Pattern:

// Equivalent to SDK's V4Planner
bytes memory v4Actions = abi.encodePacked(action1, action2, action3);
bytes[] memory actionParams = [params1, params2, params3];
bytes memory v4Params = abi.encode(actionParams);
bytes memory encodedV4Actions = abi.encode(v4Actions, v4Params);

// Equivalent to SDK's RoutePlanner
bytes memory commands = abi.encodePacked(bytes1(0x10));  // V4_SWAP
bytes[] memory inputs = [encodedV4Actions];
universalRouter.execute{value: ethAmount}(commands, inputs, deadline);

Hardcoded Base Mainnet Configuration:

All deployment parameters are now hardcoded as constants, requiring zero constructor arguments:

• TRIA Token: 0xD852713dD8dDF61316DA19383D0c427aDb85EB07
• Universal Router: 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD
• WETH: 0x4200000000000000000000000000000000000006
• Pool Manager: 0x7Da1D65F8B249183667cdE74C5CBD46dD38AA829
• PoolKey: Computed at compile-time from TRIA/WETH pool parameters
  • currency0: WETH (0x4200000000000000000000000000000000000006)
  • currency1: TRIA (0xD852713dD8dDF61316DA19383D0c427aDb85EB07)
  • fee: 3000 (3%)
  • tickSpacing: 200
  • hooks: 0xd60D6B218116cFd801E28F78d011a203D2b068Cc

Simplified Deployment:

// Old approach - required 5 constructor parameters
constructor(
    address _triaToken,
    address _universalRouter,
    address _weth,
    address _poolManager,
    bytes32 _poolKey
) { ... }

// New approach - zero constructor parameters needed
constructor() {
    owner = msg.sender;
    deploymentTime = block.timestamp;
    currentPeriod = 1;
}

Simply deploy the contract without any arguments - it's pre-configured for Base mainnet!

Compilation Fixes:

1. Stack Too Deep: Split getUserInfo function to use helper _getClaimInfo
2. Shadowing Warning: Renamed now variable to currentTime (avoids shadowing deprecated keyword)
3. Result: Compiles cleanly with zero warnings or errors using standard --optimize flag

Original prompt

Fix the Uniswap V4 Universal Router swap function in EtherTrialsPointBased_v6.sol.

The current _swapETHToTRIAV4 function uses an incorrect nested command structure that doesn't match Universal Router's expected format.

Current issues:

1. Tries to encode multiple actions (SWAP_EXACT_IN_SINGLE_ACTION, SETTLE_ALL_ACTION, TAKE_ALL_ACTION) into a single nested command
2. Uses incorrect parameters format - abi.encode(actions, params) is not valid
3. Commands and inputs arrays don't align properly - 1 command but trying to handle 3 sub-actions

Required fix:

1. Replace nested structure with sequential commands (V4_SWAP, WRAP_ETH, SWEEP)
2. Use proper input encoding for each command separately
3. Ensure commands.length == inputs.length with proper alignment
4. Follow Uniswap Universal Router v2 architecture where each command gets its own input

The correct command IDs from Uniswap/universal-router are:

• 0x10 = V4_SWAP
• 0x0b = WRAP_ETH
• 0x04 = SWEEP

The example you shared is for Uniswap V2, which uses swapExactETHForTokens. However, this implementation is specifically for Uniswap V4 Universal Router, which has a different architecture.

V4 uses the Universal Router's command-based execution system where we send ETH via the {value: ethAmount} call option (line 290), and the router handles the wrapping internally via the WRAP_ETH command (0x0b).

The key differences:

• V2: Direct functions like swapExactETHForTokens()
• V4 Universal Router: Command-based with execute(commands, inputs, deadline) where commands are sequential operations (WRAP_ETH → V4_SWAP → SWEEP)

The current implementation correctly follows the V4 Universal Router v2 specification as requested in the original problem statement. (commit eb10a8a)

@copilot Executing a Single-Hop Swap
Introduction

This guide will build off our quoting guide and show how to use a quote to construct and execute a trade on the Uniswap v4 protocol. In this example we will trade between two tokens: ETH and USDC.

The guide will cover:

Setting up swap parameters and pool configuration
Using Universal Router and executing a single-hop swap

At the end of this guide, you should be able to execute swaps between any two tokens using a single pool on Uniswap V4.

For this guide, the following Uniswap packages are used:

@uniswap/v4-sdk
@uniswap/sdk-core
@uniswap/universal-router-sdk

Setting up Swap Configuration

First, let's define our swap configuration. We will use the same pool structure from the quoting guide:

import { SwapExactInSingle } from '@uniswap/v4-sdk'
import { USDC_TOKEN, ETH_TOKEN } from './constants'

export const CurrentConfig: SwapExactInSingle = {
poolKey: {
currency0: ETH_TOKEN.address,
currency1: USDC_TOKEN.address,
fee: 500,
tickSpacing: 10,
hooks: "0x0000000000000000000000000000000000000000",
},
zeroForOne: true, // The direction of swap is ETH to USDC. Change it to 'false' for the reverse direction
amountIn: ethers.utils.parseUnits('1', ETH_TOKEN.decimals).toString(),
amountOutMinimum: "minAmountOut", // Change according to the slippage desired
hookData: '0x00'
}

Like the quoting guide, the pool used is defined by a pair of tokens in constants.ts. You can change these two tokens and the other pool parameters in the config as long as a pool actually exists for that configuration.
Using Universal Router and executing a single-hop swap

The Universal Router is a flexible, gas-efficient contract designed to execute complex swap operations across various protocols, including Uniswap v4. It serves as an intermediary between users and the Uniswap v4 PoolManager, handling the intricacies of swap execution.

So, we construct an instance of an ethers Contract for the Universal Router contract in order to interact with it:

const UNIVERSAL_ROUTER_ADDRESS = "0x66a9893cc07d91d95644aedd05d03f95e1dba8af" // Change the Universal Router address as per the chain

const UNIVERSAL_ROUTER_ABI = [
{
inputs: [
{ internalType: "bytes", name: "commands", type: "bytes" },
{ internalType: "bytes[]", name: "inputs", type: "bytes[]" },
{ internalType: "uint256", name: "deadline", type: "uint256" },
],
name: "execute",
outputs: [],
stateMutability: "payable",
type: "function",
},
]

const universalRouter = new ethers.Contract(
UNIVERSAL_ROUTER_ADDRESS,
UNIVERSAL_ROUTER_ABI,
signer
)

We can get the UNIVERSAL_ROUTER_ADDRESS for our chain from Uniswap Deployments.

A signer object can be created like this:

const provider = new ethers.providers.JsonRpcProvider("RPC");
const signer = new ethers.Wallet(
"YOUR PRIVATE KEY",
provider
);

Now, let's implement the main function that handles the swap. When encoding a swap command for the Universal Router, we need to choose between two types of swaps:

Exact Input Swaps: Use this swap-type when you know the exact amount of tokens you want to swap in, and you're willing to accept any amount of output tokens above your minimum. This is common when you want to sell a specific amount of tokens.
Exact Output Swaps: Use this swap-type when you need a specific amount of output tokens, and you're willing to spend up to a maximum amount of input tokens. This is useful when you need to acquire a precise amount of tokens, for example, to repay a loan or meet a specific requirement.

We will be doing an Exact Input swap in this example.

import { Actions, V4Planner } from '@uniswap/v4-sdk'
import { CommandType, RoutePlanner } from '@uniswap/universal-router-sdk'

const v4Planner = new V4Planner()
const routePlanner = new RoutePlanner()

// Set deadline (1 hour from now)
const deadline = Math.floor(Date.now() / 1000) + 3600

v4Planner.addAction(Actions.SWAP_EXACT_IN_SINGLE, [CurrentConfig]);
v4Planner.addAction(Actions.SETTLE_ALL, [CurrentConfig.poolKey.currency0, CurrentConfig.amountIn]);
v4Planner.addAction(Actions.TAKE_ALL, [CurrentConfig.poolKey.currency1, CurrentConfig.amountOutMinimum]);

const encodedActions = v4Planner.finalize()

routePlanner.addCommand(CommandType.V4_SWAP, [v4Planner.actions, v4Planner.params])

// Only needed for native ETH as input currency swaps
const txOptions: any = {
value: CurrentConfig.amountIn
}

const tx = await universalRouter.execute(
routePlanner.commands,
[encodedActions],
deadline,
txOptions
)

const receipt = await tx.wait()
console.log('Swap completed! Transaction hash:', receipt.transactionHash)

The actions in the planner define the sequence of operations that will be performed in our v4 swap:

SWAP_EXACT_IN_SINGLE: This action specifies that we want to perform an exact input swap using a single pool.
SETTLE_ALL: This action ensures all input tokens involved in the swap are properly paid. This is part of v4's settlement pattern for handling token transfers.
TAKE_ALL: This final action collects all output tokens after the swap is complete.

The sequence of these actions is important as they define the complete flow of our swap operation from start to finish. The input and output currencies should be exchanged for the SETTLE_ALL and TAKE_ALL actions if the direction of the swap is reversed.

The V4_SWAP command tells the Universal Router that we want to perform a swap on a Uniswap v4 pool.
Handling Token Approvals for ERC20 Swaps

When swapping ERC20 tokens, we need to set up approvals through Permit2. So, we construct an instance of an ethers Contract for the Permit2 contract in order to interact with it:

const permit2Contract = new ethers.Contract(
PERMIT2_ADDRESS,
PERMIT2_ABI,
signer
)

Create a similar one for the ERC20 token contract. If enough allowances have not been provided or the deadline has expired, we first need to approve Permit2 as a spender on the ERC20 token and then approve the Universal Router on Permit2.

const tx1 = await erc20Contract.approve(PERMIT2_ADDRESS, ethers.constants.MaxUint256)
const tx2 = await permit2Contract.approve(
tokenAddress,
UNIVERSAL_ROUTER_ADDRESS,
ethers.BigNumber.from(2).pow(160).sub(1), // MAX_UINT160
deadline
)

The rest of the swap process remains the same.

@copilot Executing a Single-Hop Swap
Introduction
...

Updated the implementation to match the official Uniswap V4 SDK pattern from the documentation you shared.

Key changes:

• Now uses a single V4_SWAP (0x10) command instead of three separate commands
• V4 actions (SWAP_EXACT_IN_SINGLE, SETTLE_ALL, TAKE_ALL) are encoded together as input
• Follows the V4Planner pattern: addCommand(V4_SWAP, [encodedV4Actions])
• Parameters properly structured for each V4 action

The previous approach incorrectly treated WRAP_ETH and SWEEP as separate Universal Router commands, when they should be V4 actions encoded within a single V4_SWAP command. (commit 4735cca)

@copilot Getting a Quote
Introduction

This guide will cover how to get the current quotes for any token pair on the Uniswap protocol.

In this example we will use quoteExactInputSingle to get a quote for the pair ETH - USDC. The inputs are poolKey, zeroForOne, exactAmount and hookData.

The guide will cover:

Constructing the PoolKey and swap parameters
Referencing the Quoter contract and getting a quote

At the end of the guide, we should be able to fetch the output for the given token pair and input amount.

For this guide, the following Uniswap packages are used:

@uniswap/v4-sdk
@uniswap/sdk-core

Constructing the PoolKey and Swap parameters

We will first create an example configuration CurrentConfig in config.ts. For this example, we are using the 0.05% ETH - USDC pool which has the format:

import { SwapExactInSingle } from '@uniswap/v4-sdk'
import { USDC_TOKEN, ETH_TOKEN } from './constants'
import { parseUnits, JsonRpcProvider, formatUnits } from 'ethers'

export const CurrentConfig: SwapExactInSingle = {
poolKey: {
currency0: ETH_TOKEN.address,
currency1: USDC_TOKEN.address,
fee: 500,
tickSpacing: 10,
hooks: "0x0000000000000000000000000000000000000000",
},
zeroForOne: true,
amountIn: parseUnits('1', ETH_TOKEN.decimals).toString(),
amountOutMinimum: "0",
hookData: '0x00'
}

The pool used is defined by a pair of tokens in constants.ts. You can also change these two tokens and the other pool parameters in the config, just make sure a pool actually exists for your configuration. Check out the top pools on Uniswap.

import { Token, ChainId } from '@uniswap/sdk-core'

export const ETH_TOKEN = new Token(
ChainId.MAINNET,
'0x0000000000000000000000000000000000000000',
18,
'ETH',
'Ether'
)

export const USDC_TOKEN = new Token(
ChainId.MAINNET,
'0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48',
6,
'USDC',
'USDC'
)

Referencing the Quoter contract and getting a quote

To get quotes for trades, Uniswap has deployed a Quoter Contract. We will use this contract to fetch the output amount we can expect for our trade, without actually executing the trade.

Now, we need to construct an instance of an ethers Contract for our Quoter contract in order to interact with it:

const quoterContract = new ethers.Contract(
QUOTER_CONTRACT_ADDRESS,
QUOTER_ABI, // Import or define the ABI for Quoter contract
new JsonRpcProvider("RPC") // Provide the right RPC address for the chain
)

We get the QUOTE_CONTRACT_ADDRESS for our chain from Uniswap Deployments.

We can now use our Quoter contract to obtain the quote.

In an ideal world, the quoter functions would be view functions, which would make them very easy to query on-chain with minimal gas costs. However, the Uniswap V4 Quoter contracts rely on state-changing calls designed to be reverted to return the desired data. This means calling the quoter will be very expensive and should not be called on-chain.

To get around this difficulty, we can use the callStatic method provided by the ethers.js Contract instances. This is a useful method that submits a state-changing transaction to an Ethereum node, but asks the node to simulate the state change, rather than to execute it. Our script can then return the result of the simulated state change:

const quotedAmountOut = await quoterContract.callStatic.quoteExactInputSingle({
poolKey: CurrentConfig.poolKey,
zeroForOne: CurrentConfig.zeroForOne,
exactAmount: CurrentConfig.amountIn,
hookData: CurrentConfig.hookData,
})

console.log(formatUnits(quotedAmountOut.amountOut, USDC_TOKEN.decimals));

The result of the call is the number of output tokens you would receive for the quoted swap.

It should be noted that quoteExactInputSingle is only 1 of 4 different methods that the quoter offers:

quoteExactInputSingle - given an input amount, produce a quote of the output amount for a swap on a single pool
quoteExactInput - given an input amount, produce a quote for the output amount a swap over multiple pools
quoteExactOutputSingle - given a desired output amount, produce a quote for the input amount on a swap over a single pool
quoteExactOutput - given a desired output amount, produce a quote for the input amount in for a swap over multiple pools

If we want to trade two tokens that do not share a pool with each other, we will need to make swaps over multiple pools. This is where the quoteExactInput and quoteExactOutput methods come in.

For the exactOutput and exactOutputSingle methods, we need to keep in mind that a pool can not give us more than the amount of Tokens it holds. If we try to get a quote on an output of 100 ETH from a pool that only holds 50 ETH, the function call will fail.

Executing Multi-Hop Swaps
Introduction

This guide demonstrates how to execute multi-hop swaps on Uniswap V4, allowing you to trade between tokens that might not share a direct pool. Multi-hop swaps route through multiple pools to achieve the desired token exchange, often providing better pricing than attempting direct swaps through less liquid pools.

Building on our single-hop swap guide, this guide will show you how to construct routing paths and execute them efficiently.

The guide will cover:

Constructing swap paths through multiple pools
Executing the multi-hop swap

At the end of this guide, you should be able to execute swaps between any two tokens using optimal routing through multiple pools.

For this guide, the following Uniswap packages are used:

@uniswap/v4-sdk
@uniswap/sdk-core
@uniswap/universal-router-sdk

Constructing swap paths through multiple pools

Let's first define a multi-hop swap configuration. In this example, we'll swap ETH → USDC → USDT. The configuration follows closely from the quoting and single-hop swapping guides.

import { SwapExactIn, PoolKey } from '@uniswap/v4-sdk'
import { ETH_TOKEN, USDC_TOKEN, USDT_TOKEN } from './constants'

const ETH_USDC_POOL_KEY: PoolKey = {
currency0: ETH_TOKEN.address,
currency1: USDC_TOKEN.address,
fee: 3000,
tickSpacing: 60,
hooks: "0x0000000000000000000000000000000000000000",
};

const USDC_USDT_POOL_KEY: PoolKey = {
currency0: USDC_TOKEN.address,
currency1: USDT_TOKEN.address,
fee: 10,
tickSpacing: 1,
hooks: "0x0000000000000000000000000000000000000000",
};

export const CurrentConfig: SwapExactIn = {
currencyIn: ETH_TOKEN.address,
path: encodeMultihopExactInPath(
[ETH_USDC_POOL_KEY, USDC_USDT_POOL_KEY],
ETH_TOKEN.address
),
amountIn: ethers.utils.parseUnits('1', ETH_TOKEN.decimals).toString(),
amountOutMinimum: "minAmountOut", // Change according to the slippage desired
}

Uniswap V4 uses a specific format for encoding multi-hop paths. Each hop in the path requires:

type PathKey = {
intermediateCurrency: string;
fee: number;
tickSpacing: number;
hooks: string;
hookData: string;
};

We can encode the path using a function like:

export function encodeMultihopExactInPath(
poolKeys: PoolKey[],
currencyIn: string
): PathKey[] {
const pathKeys: PathKey[] = []
let currentCurrencyIn = currencyIn

for (let i = 0; i < poolKeys.length; i++) {
// Determine the output currency for this hop
const currencyOut = currentCurrencyIn === poolKeys[i].currency0
? poolKeys[i].currency1
: poolKeys[i].currency0

// Create path key for this hop
const pathKey: PathKey = {
  intermediateCurrency: currencyOut,
  fee: poolKeys[i].fee,
  tickSpacing: poolKeys[i].tickSpacing,
  hooks: poolKeys[i].hooks,
  hookData: '0x'
}

pathKeys.push(pathKey)
currentCurrencyIn = currencyOut // Output becomes input for next hop

}

return pathKeys
}

Executing the multi-hop swap

We'll use the same contract addresses and ABIs from the single-hop guide and construct the ethers Contract for them:

const UNIVERSAL_ROUTER_ADDRESS = "0x66a9893cC07D91D95644AEDD05D03f95e1dBA8Af"
const PERMIT2_ADDRESS = "0x000000000022D473030F116dDEE9F6B43aC78BA3"

// ABIs remain the same as in single-hop guide
const UNIVERSAL_ROUTER_ABI = [/* ... /]
const ERC20_ABI = [/ ... /]
const PERMIT2_ABI = [/ ... */]

The main function for executing multi-hop swaps is very similar to the single-hop guide as well. The only difference is that the first action to the Universal Router is SWAP_EXACT_IN instead of SWAP_EXACT_IN_SINGLE.

import { Actions, V4Planner } from '@uniswap/v4-sdk'
import { CommandType, RoutePlanner } from '@uniswap/universal-router-sdk'

const v4Planner = new V4Planner()
const routePlanner = new RoutePlanner()

const deadline = Math.floor(Date.now() / 1000) + 3600

v4Planner.addAction(Actions.SWAP_EXACT_IN, [CurrentConfig]);
v4Planner.addAction(Actions.SETTLE_ALL, [ETH_USDC_POOL_KEY.currency0, CurrentConfig.amountIn]);
v4Planner.addAction(Actions.TAKE_ALL, [USDC_USDT_POOL_KEY.currency1, CurrentConfig.amountOutMinimum]);

const encodedActions = v4Planner.finalize()

routePlanner.addCommand(CommandType.V4_SWAP, [v4Planner.actions, v4Planner.params])

// Only needed for native ETH as input currency swaps
const txOptions: any = {
value: CurrentConfig.amountIn
}

const tx = await universalRouter.execute(
routePlanner.commands,
[encodedActions],
deadline,
txOptions
)

const receipt = await tx.wait()
console.log('Multi-hop swap completed! Transaction hash:', receipt.transactionHash)

The token approvals for ERC20 token swaps remain the same as the single-hop swapping guide.

@copilot Getting a Quote
Introduction
...

Saya telah memperbarui contract dengan pola yang lebih akurat dari dokumentasi SDK yang Anda berikan.

Peningkatan yang diterapkan:

• Parameter encoding sekarang lebih eksplisit mengikuti pola SDK V4Planner
• Setiap action (SWAP_EXACT_IN_SINGLE, SETTLE_ALL, TAKE_ALL) memiliki parameter yang di-encode secara terpisah dalam array
• Dokumentasi ditambahkan dengan referensi lengkap ke guide quoting dan multi-hop swaps
• Struktur encoding sekarang sama persis dengan: abi.encode(v4Actions, v4Params) dimana v4Params adalah array of encoded parameters

Contract ini menggunakan single-hop swap karena hanya perlu ETH → TRIA secara langsung. Jika nanti perlu multi-hop (misalnya ETH → USDC → TRIA), action SWAP_EXACT_IN_SINGLE bisa diganti dengan SWAP_EXACT_IN dan path encoding bisa ditambahkan.

Fixed the compiler warning by renaming the now variable to currentTime in the getPeriodInfo function.

The variable name now was shadowing a deprecated Solidity builtin keyword (alias for block.timestamp). Contract now compiles with zero warnings or errors. (commit b787435)

"0xd852713dd8ddf61316da19383d0c427adb85eb07"
_universalRouter:...

Untuk deployment parameter di Base mainnet:

Universal Router:

• Address: 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD (Uniswap Universal Router)
• Atau cek: https://docs.uniswap.org/contracts/v4/deployments

WETH (Wrapped ETH):

• Base mainnet: 0x4200000000000000000000000000000000000006

Pool Manager (Uniswap V4):

• Cek deployment addresses di: https://docs.uniswap.org/contracts/v4/deployments
• Atau gunakan address dari dokumen DEX_ROUTER_GUIDE.md di repo

PoolKey (bytes32):

• Ini adalah hash dari pool parameters: keccak256(abi.encode(currency0, currency1, fee, tickSpacing, hooks))
• Perlu di-generate berdasarkan TRIA/WETH pool yang Anda gunakan
• Currency0 dan currency1 diurutkan: address yang lebih kecil = currency0

Untuk $TRIA token Anda sudah ada: 0xd852713dd8ddf61316da19383d0c427adb85eb07

Saran: Cek dulu apakah sudah ada pool TRIA/WETH di Uniswap V4 Base, karena itu yang akan menentukan poolKey yang valid.

[ismaonezain]

@copilot deploynya butuh poolmanager sama poolkey ini gabisa dicari

[Copilot]

@copilot deploynya butuh poolmanager sama poolkey ini gabisa dicari

Untuk Base mainnet, berikut adalah address yang sudah di-deploy:

PoolManager (Uniswap V4 di Base):

• Address: 0x7Da1D65F8B249183667cdE74C5CBD46dD38AA829
• Sumber: https://docs.uniswap.org/contracts/v4/deployments

Untuk PoolKey:
Karena ini adalah parameter spesifik pool, ada 2 opsi:

Opsi 1 - Jika pool TRIA/WETH belum ada:

• Anda perlu membuat pool baru dulu menggunakan PoolManager
• PoolKey akan di-generate saat pool dibuat
• Pool parameters yang diperlukan: currency0, currency1, fee (contoh: 3000 untuk 0.3%), tickSpacing, hooks

Opsi 2 - Untuk testing/development:

• Set poolKey sebagai bytes32(0) atau dummy value saat deployment
• Update nanti setelah pool TRIA/WETH dibuat
• Tambahkan function setPoolKey() onlyOwner untuk update:

function setPoolKey(bytes32 _newPoolKey) external onlyOwner {
    poolKey = _newPoolKey;
}

Saran: Deploy dulu dengan dummy poolKey, lalu create pool TRIA/WETH di Uniswap V4, kemudian update poolKey via setter function.

@copilot pool TRIA/WETH uniswap v4 udah ada, cuma gua gangerti nyari pool keynya

[Copilot]

@copilot pool TRIA/WETH uniswap v4 udah ada, cuma gua gangerti nyari pool keynya

Kalau pool sudah ada, ada beberapa cara untuk mendapatkan poolKey:

Cara 1 - Hitung poolKey dari pool parameters:
PoolKey adalah hash dari pool parameters. Anda perlu tahu:

• currency0: Address token yang lebih kecil (compare WETH vs TRIA, pilih yang lebih kecil)
• currency1: Address token yang lebih besar
• fee: Pool fee tier (contoh: 500 = 0.05%, 3000 = 0.3%, 10000 = 1%)
• tickSpacing: Spacing antar tick (tergantung fee tier)
• hooks: Hook contract address (atau 0x0000... jika no hooks)

Lalu encode dengan:

bytes32 poolKey = keccak256(abi.encode(
    currency0,
    currency1,
    fee,
    tickSpacing,
    hooks
));

Cara 2 - Query dari PoolManager contract:
Call function getPool() di PoolManager dengan parameters di atas untuk verify pool exists, lalu compute poolKey nya.

Cara 3 - Lihat dari Uniswap V4 explorer/interface:

• Cek di https://app.uniswap.org atau Base explorer
• Lihat pool TRIA/WETH transaction history
• Ambil pool parameters dari pool creation event

Info yang perlu:

• WETH Base: 0x4200000000000000000000000000000000000006
• TRIA: 0xd852713dd8ddf61316da19383d0c427adb85eb07
• Compare: WETH < TRIA, jadi currency0 = WETH, currency1 = TRIA

Bisa coba query di block explorer untuk event Initialize dari PoolManager saat pool dibuat.

Dengan parameter yang Anda berikan, berikut cara calculate poolKey:

Pool Parameters:

currency0: 0x4200000000000000000000000000000000000006 (WETH - address lebih kecil)
currency1: 0xd852713dd8ddf61316da19383d0c427adb85eb07 (TRIA)
fee: 3000 (3% = 3000 basis points, bukan "dynamic 3%")
tickSpacing: 200
hooks: 0xd60D6B218116cFd801E28F78d011a203D2b068Cc

Cara calculate poolKey:

Di Solidity:

bytes32 poolKey = keccak256(abi.encode(
    address(0x4200000000000000000000000000000000000006), // currency0 (WETH)
    address(0xd852713dd8ddf61316da19383d0c427adb85eb07), // currency1 (TRIA)
    uint24(3000),                                          // fee (3%)
    int24(200),                                            // tickSpacing
    address(0xd60D6B218116cFd801E28F78d011a203D2b068Cc)  // hooks
));

Atau gunakan web3/ethers untuk calculate:

const poolKey = ethers.utils.keccak256(
  ethers.utils.defaultAbiCoder.encode(
    ['address', 'address', 'uint24', 'int24', 'address'],
    [
      '0x4200000000000000000000000000000000000006',
      '0xd852713dd8ddf61316da19383d0c427adb85eb07',
      3000,
      200,
      '0xd60D6B218116cFd801E28F78d011a203D2b068Cc'
    ]
  )
);

Hasil poolKey ini yang digunakan saat deployment contract.

@copilot kenapa ga langsung set saja di contract jd aku tidak perlu masukkan apapun saat deploy?

Sudah diubah! Sekarang semua parameter sudah di-hardcode di contract:

Yang diubah:

• TRIA token address: 0xD852713dD8dDF61316DA19383D0c427aDb85EB07
• Universal Router: 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD
• WETH: 0x4200000000000000000000000000000000000006
• Pool Manager: 0x7Da1D65F8B249183667cdE74C5CBD46dD38AA829
• PoolKey: Otomatis di-calculate dari pool parameters TRIA/WETH

Deployment sekarang:

// Constructor tidak perlu parameter apapun
constructor() {
    owner = msg.sender;
    deploymentTime = block.timestamp;
    // ... initialization
}

Tinggal deploy tanpa input parameter apapun, langsung siap pakai untuk Base mainnet! (commit c8170eb)
