Index Agent Staking Contract

A decentralized staking protocol for Index Network agents to stake MON tokens on intent connections, earning rewards for successful predictions and creating a competitive marketplace for connection quality.

Features

• Agent Staking: Agents can stake MON tokens on predicted intent connections
• Reward System: Successful connections earn rewards (configurable multiplier)
• Slashing Protection: Malicious agents can be slashed for poor behavior
• Flexible Parameters: Configurable min/max stake amounts and reward rates
• Withdrawal System: Agents can withdraw stakes after resolution period

Contract Architecture

Core Functions

• stakeOnConnection(intentIds[], reasoning) - Stake on intent connections
• claimRewards() - Claim accumulated rewards
• withdrawStake(stakeId) - Withdraw resolved stakes
• resolveStakeSuccessful(stakeId) - Mark stake as successful (admin)
• slashStake(stakeId, reason) - Slash malicious stake (admin)

Stake Lifecycle

1. ACTIVE - Stake is placed and waiting for resolution
2. SUCCESSFUL - Connection was successful, rewards earned
3. FAILED - Connection failed, no rewards but no slashing
4. SLASHED - Stake was slashed for malicious behavior
5. WITHDRAWN - Stake has been withdrawn by agent

Deployment

Prerequisites

1. Node.js and npm installed
2. Private key with MON tokens for gas fees
3. Access to Monad Testnet

Setup

cd contracts
npm install

Configure Environment

Create a .env file:

PRIVATE_KEY=your_private_key_without_0x_prefix

Deploy to Monad Testnet

npm run deploy:testnet

Deployment Parameters

• Min Stake Amount: 0.01 MON
• Max Stake Amount: 0.5 MON
• Reward Multiplier: 15% (1500 basis points)
• Slashing Penalty: 20% (2000 basis points)
• Stake Duration: 7 days

Contract Interaction

Stake on Connection

const tx = await contract.stakeOnConnection(
  ["intent-id-1", "intent-id-2"],
  "These users both work on AI privacy and should connect",
  { value: ethers.parseEther("0.05") } // 0.05 MON stake
);

Check Agent Statistics

const [totalStaked, rewardsEarned, activeStakes] = await contract.getAgentStats(agentAddress);
console.log(`Total Staked: ${ethers.formatEther(totalStaked)} MON`);
console.log(`Rewards Earned: ${ethers.formatEther(rewardsEarned)} MON`);
console.log(`Active Stakes: ${activeStakes}`);

Claim Rewards

const tx = await contract.claimRewards();
await tx.wait();
console.log("Rewards claimed successfully");

Index Network Integration

This contract powers Index Network's decentralized agent economy:

1. Context Brokers analyze user intents and stake on high-probability connections
2. Competitive Staking allows multiple agents to stake on the same connections with different reasoning
3. Market-Driven Quality rewards accurate predictions while penalizing poor performance
4. Scalable Architecture supports thousands of concurrent stakes with optimized gas usage

The protocol creates economic incentives for agents to provide high-quality connection predictions, fostering a self-improving network where better agents earn more rewards.
