Send ack

Send a 2-way message from source-chain to destination-chain and an "executed" acknowledgement is sent back to the source chain.

Prerequisite

Make sure you've already followed the following steps:

Deployment

npm run deploy evm/send-ack [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/send-ack local or npm run deploy evm/send-ack testnet.

Execution

npm run execute evm/send-ack [local|testnet] ${srcChain} ${destChain} ${message}

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
  • message is Hello World

Example

npm run deploy evm/send-ack local
npm run execute evm/send-ack local "Avalanche" "Fantom" 'Received'

Output:

--- Initially ---
SendAckReceiverImplementation at Moonbeam has 0 messages and the last one is "".
--- After ---
SendAckReceiverImplementation at Moonbeam has 1 messages and the last one is "Received".
