Provider adapter that wraps an ethers Provider or EIP-1193 source for read-only chain access. Implements GenericProvider.

Import

import { EthersProvider } from "@zama-fhe/sdk/ethers";

Usage

ethers Provider

import { JsonRpcProvider } from "ethers";
import { EthersProvider } from "@zama-fhe/sdk/ethers";

const ethersProvider = new JsonRpcProvider("https://sepolia.infura.io/v3/YOUR_KEY");
const provider = new EthersProvider({ provider: ethersProvider });

EIP-1193

import { EthersProvider } from "@zama-fhe/sdk/ethers";

const provider = new EthersProvider({ ethereum: window.ethereum! });

You rarely need to instantiate EthersProvider directly. The ethers createConfig builds one from the configuration you pass. Use this class when constructing ZamaSDK manually or when using the generic createConfig.

Constructor

Pass exactly one of the two parameters below.

provider

ethers.Provider

Pre-built ethers provider (e.g. JsonRpcProvider, WebSocketProvider).

const provider = new EthersProvider({ provider: new JsonRpcProvider(rpcUrl) });

const provider = new EthersProvider({ ethereum: window.ethereum! });
