ethereum-gasless-extension

Exposes the EVM gas sponsorship surface of @dynamic-labs/ethereum-gasless-core as a ethereumGasless namespace on the Dynamic client. Works for both the web and React Native (WebView) consumers — the extension forwards each call across messageTransport to the EthereumGaslessController in webview-controller, which holds the wallet keys.

Installation

npm install @dynamic-labs/ethereum-gasless-extension

Usage

import { EthereumGaslessExtension } from '@dynamic-labs/ethereum-gasless-extension';
import { createClient } from '@dynamic-labs/legacy-client';

const dynamicClient = createClient({
  /* ... */
}).extend(EthereumGaslessExtension());

// Send a sponsored transaction end-to-end.
const wallet = dynamicClient.wallets.primary;
const { transactionHash } = await dynamicClient.ethereumGasless.send({
  wallet,
  calls: [{ target: '0x...', data: '0x', value: 0n }],
});

// Or split signing and relaying for retries / batching.
const signed = await dynamicClient.ethereumGasless.sign({ wallet, calls });
const { requestId } = await dynamicClient.ethereumGasless.relay({
  wallet,
  calls,
});
const status = await dynamicClient.ethereumGasless.getStatus({ requestId });
