2. IntelliJ is recommended for developing Move contracts. Install the Move Intellij IDE Plugin.

---

Testing

Run Aptos and EVM Local Network

./docker-start-containers.sh

Run Unit Tests for All Package Modules

make test

Running E2E Tests

# Install Dependencies
yarn install

# Run e2e tests
yarn test:e2e

Running Example Scripts on Testnet

1. Rename .env.example to .env and fill in the required environment variables.
2. Run the example script for Base/EVM -> Aptos

yarn receive-message-example

3. Run the example script for Aptos -> Base/EVM

yarn deposit-for-burn-example

Deployment

1. Create a deployer keypair and fund it with APT
2. Deploy MessageTransmitter and TokenMessengerMinter package

yarn deploy --privateKey=<key> --rpc=<rpcUrl>  --aptosExtensionsPackageId=<packageId> --stablecoinPackageId=<packageId>

3. Verify source bytecode

# Message Transmitter
yarn verify-pkg --packageName=message_transmitter --rpc=<rpcUrl> --packageId=<MessageTransmitterPackageId> --namedDeps aptos_extensions=<packageId>,deployer=<deployerAccountAddress>

# TokenMessengerMinter
yarn verify-pkg --packageName=token_messenger_minter --rpc=<rpcUrl> --packageId=<TokenMessengerMinterPackageId> --namedDeps aptos_extensions=<packageId>,deployer=<deployerAccountAddress>,message_transmitter=<packageId>,stablecoin=<packageId>

Upgrading

1. Build payload for publishing

# Message Transmitter
aptos move build-publish-payload --package-dir packages/message_transmitter --named-addresses deployer=<deployerAccountAddress>,aptos_extensions=<packageId>,message_transmitter=<packageId> --json-output-file upgrade.json

# Token Messenger Minter
aptos move build-publish-payload --package-dir packages/token_messenger_minter --named-addresses deployer=<deployerAccountAddress>,aptos_extensions=<packageId>,message_transmitter=<packageId>,stablecoin=<packageId>,token_messenger_minter=<packageId> --json-output-file upgrade.json

2. Execute Tx for upgrading

yarn upgrade-pkg --privateKey=<upgradeAdminKey> --rpc=<rpcUrl> --payloadFilePath=upgrade.json --aptosExtensionsPackageId=<packageId> --packageId=<packageId>
