@interep/identity v0.3.0

The @interep/identity package allows you to create Semaphore identities by deriving them from a message signed with an Ethereum account. The identity can be used to generate identity commitments and other parameters needed to create zero-knowledge proofs with Semaphore.

🛠 Install

📜 Usage

# createIdentity(sign: (message: string) => Promise\<string>, provider: string, nonce?: number): ZKIdentity

import createIdentity from "@interep/identity"
import detectEthereumProvider from "@metamask/detect-provider"
import { ethers } from "ethers"

const ethereumProvider = (await detectEthereumProvider()) as any
const provider = new ethers.providers.Web3Provider(ethereumProvider)
const signer = provider.getSigner()

const identity = await createIdentity((message) => signer.signMessage(message), "Twitter")
