Relay - Solana Messenger dApp

This is an example of an on-chain decentralized Messaging dapp. This example is a relay chat dapp where you can create, read, update, and delete messaging entries on the solana blockchain and interact with the solana program via a UI. Please note that this only works with Anchor version 0.29.0 for now 🥺.

Apps

Anchor

This is a Solana program written in Rust using the Anchor framework.

Note: The solana program code for the relay dapp can be found in anchor/programs/src/lib.rs

Commands

You can use any normal anchor commands. Either move to the anchor directory and run the anchor command or prefix the command with npm run, eg: npm run anchor.

Sync the program id:

Running this command will create a new keypair in the anchor/target/deploy directory and save the address to the Anchor config file and update the declare_id! macro in the ./src/lib.rs file of the program.

You will manually need to update the constant in anchor/lib/counter-exports.ts to match the new program id. For this version, you can cd anchor first to get to anchor directory.

anchor keys sync 
npm run anchor keys sync

Build the program:

anchor build
npm run anchor-build

Start the test validator with the program deployed:

npm run anchor-localnet

Run the tests

npm run anchor-test

Deploy to Devnet

anchor deploy --provider.cluster testnet
(or)
anchor deploy --provider.cluster devnet
npm run anchor deploy --provider.cluster devnet

Web

This is a React app that uses the Anchor generated client to interact with the Solana program. You can cd to root or cd ..
