UniRep contract helpers

getUnirepContract

Connect to a Unirep contract with a given Unirep address.

const getUnirepContract = (
    address: string,
    signerOrProvider: ethers.Signer | ethers.providers.Provider
): Unirep

For example,

import { getUnirepContract } from '@unirep/contracts'

const unirep = getUnirepContract(
    address,          // the address of UniRep contract
    signerOrProvider, // the signer of the provider
)

genSignature

Generate signature for attester if the attester signs up through attesterSignUpViaRelayer.

const genSignature = async (
    unirepAddress: string,
    attester: ethers.Signer | ethers.Wallet,
    epochLength: number
)

For example,

import { genSignature } from '@unirep/contracts'

// generate the signature
const signature = genSignature(
    address,     // the address of UniRep contract
    signer,      // the signer of the attester
    epochLength, // the epoch length of the attester
)

// sign up with UniRep contract
const tx = await unirep.attesterSignUpViaRelayer(
    signer.address,
    epochLength,
    signature
)
