Spin up the testing chain with
npx hardhat node
Use the hardhat testing chain as an example config.
PROVIDER=http://127.0.0.1:8545/
PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
{% code title="deploy.ts" %}
import { ethers } from 'ethers'
import { deployUnirep } from '@unirep/contracts'
async function main(){
const provider = await ethers.getDefaultProvider(PROVIDER)
const signer = new ethers.Wallet(
PRIVATE_KEY,
provider
)
const contract = await deployUnirep(
signer
)
console.log("Unirep address: ", contract.address)
}
main();
{% endcode %}
{% hint style="warning" %}
Now the verifiers are fixed in @unirep/contracts
so it can be deployed with deployUnirep
function.
To make verifiers more flexible, it it recommended to download Unirep repository and deploy verifiers before deploying Unirep.sol
.
