Deploy a contract gaslessly

An API key is required to use the infrastructure to power gasless transactions. Visit https://app.rallyprotocol.com/ to generate both Amoy and Mainnet Polygon API keys.

Deploy contracts with the relay method

To gaslessly deploy a contract, create a GSN transaction object and use the relay() method to send the transaction to our relayer.

var gsnTx = new GsnTransactionDetails(
  from: accountAddress,
  data: tx.data,
  value: "0",
  to: contractAddress,
  gas: gas.ToString(),
  maxFeePerGas: maxFeePerGas.ToString(),
  maxPriorityFeePerGas: maxPriorityFeePerGas.ToString(),
);

await amoy.Relay(gsnTx)


// relay arbitrary tx through our gasless relayer. see a complete Flutter example at
// https://github.com/rally-dfs/flutter-example-app/tree/main/app/lib/services/nft.dart
