cross-chain-token

Cross-chain Token Transfer

This example demonstrates how to mint tokens on a source-chain and transfer them to a destination-chain.

Prerequisite

Make sure you've already followed the following steps:

• Setup environment variables
• Run the local chains

Deployment

To deploy the contract, use the following command:

npm run deploy evm/cross-chain-token [local|testnet]

The aforementioned command pertains to specifying the intended environment for a project to execute on. It provides the option to choose between local and testnet environments by appending either local or testnet after the command.

An example of its usage is demonstrated as follows: npm run deploy evm/cross-chain-token local or npm run deploy evm/cross-chain-token testnet.

Execution

To execute the example, use the following command:

npm run execute evm/cross-chain-token [local|testnet] ${srcChain} ${destChain} ${amount}

Default Values:

• srcChain is Avalanche. Valid values are Moonbeam, Avalanche, Fantom, Ethereum, and Polygon
• destChain is Fantom. Valid values are Moonbeam, Avalanche, Fantom, Ethereum, and Polygon
• amount is 10

Example

This example deploys the contract on a local network, mints 1 token on the Ethereum chain and transfers it to the Fantom chain.

npm run deploy evm/cross-chain-token local
npm run execute evm/cross-chain-token local "Avalanche" "Fantom" 1

The output will be:

--- Initially ---
Balance at Ethereum is 0
Balance at Fantom is 0
--- After getting some token on the source chain ---
Balance at Ethereum is 1
Balance at Fantom is 0
--- After ---
Balance at Ethereum is 0
Balance at Fantom is 1
