Functions

compileVerifier

compileVerifier(contractName, vkey): Promise<{ abi: any ; bytecode: any }>

Compile the verifier smart contract with solc

Parameters

NameTypeDescription
contractNamestringThe name of output verifier contract
vkeyanyThe verification key of the verifier

Returns

Promise<{ abi: any ; bytecode: any }>

Output the compiled abi and bytecode

Defined in

packages/contracts/deploy/utils.ts:130


createVerifierName

createVerifierName(circuitName): string

Create name of the verifier contracts. Capitalize the first character and add Verifier at the end.

Parameters

NameTypeDescription
circuitNamestringName of the circuit, which can be chosen from Circuit

Returns

string

Defined in

packages/contracts/deploy/utils.ts:54


deployUnirep

deployUnirep(deployer, settings?, prover?): Promise<Unirep>

Deploy the unirep contract and verifier contracts with given deployer and settings

Parameters

NameTypeDescription
deployerSignerA signer who will deploy the contracts
settings?CircuitConfigThe settings that the deployer can define. See CircuitConfig
prover?ProverThe prover which provides vkey of the circuit

Returns

Promise<Unirep>

The Unirep smart contract

Example

import { ethers } from 'ethers'
import { Unirep } from '@unirep/contracts'
import { deployUnirep } from '@unirep/contracts/deploy'
const privateKey = 'YOUR/PRIVATE/KEY'
const provider = 'YOUR/ETH/PROVIDER'
const deployer = new ethers.Wallet(privateKey, provider);
const unirepContract: Unirep = await deployUnirep(deployer)
caution

The default circuit configuration is set in CircuitConfig.ts.
Please make sure the CircuitConfig matches your prover. If you don't compile circuits on your own, please don't change the _settings and prover.
See the current prover and settings of deployed contracts: 🤝 Testnet Deployment.
