---

🛠 Install

$3

Install the @zk-kit/protocols package with npm:

``bash
npm i @zk-kit/protocols
`

or yarn:

`bash
yarn add @zk-kit/protocols
`

📜 Usage

$3

`typescript
import { ZkIdentity } from "@zk-kit/identity"
import { generateMerkleProof } from "@zk-kit/protocols"

const depth = 20
const zeroValue = BigInt(0)
const identity = new ZkIdentity()
const identityCommitment = identity.genIdentityCommitment()
const identityCommitments = [BigInt(1), identityCommitment, BigInt(2)]

const merkleProof = generateMerkleProof(depth, zeroValue, identityCommitments, 1)
`

$3

`typescript
import { Semaphore } from "@zk-kit/protocols"

const signal = "Hello world"
const externalNullifier = BigInt(1)
const witness = Semaphore.genWitness(identity, merkleProof, externalNullifier, signal)

const { proof, publicSignals } = await Semaphore.genProof(witness, "./semaphore.wasm", "./semaphore.zkey")
const solidityProof = Semaphore.packToSolidityProof(proof)
