Smart contracts powering the bridge to Mezo

This project uses pnpm as a package manager (installation documentation).

To install dependencies run:

pnpm install

$ pnpm test

This project uses dotenv-safer, which provides environment variable checking. If there is a field in .env.example but not .env, execution will halt early with an error.

Both pnpm run deploy and pnpm test will automatically create a blank .env from the .env.example template, if .env does not exist.

To do this manually:

$ pnpm run prepare:env

We deploy our contracts with hardhat-deploy via

$ pnpm run deploy [--network <network>]

Check the "networks" entry of hardhat.config.ts for supported networks.

Deploying to real chains will require configuring the .env environment, detailed in .env.example.

In-Memory Hardhat (great for development)

pnpm run deploy

Sepolia

To deploy contracts on Sepolia run:

$ pnpm run deploy --network sepolia

Or, alternatively, manually trigger the Solidity workflow (this will not only deploy the contracts, but also update the values of TBTC_CONTRACT_ADDRESS, WBTC_CONTRACT_ADDRESS and PORTAL_CONTRACT_ADDRESS environment variables in the settings of Netlify builds deploying dApp and its previews).

The official mainnet and testnet contract addresses are listed below.
