Bridge SDK

A TypeScript SDK for interacting with the Zeko bridge, enabling deposits and withdrawals between Mina (L1) and Zeko (L2).

Installation

npm install

Build

npm run build

Usage

Initialize the Bridge

import { Bridge } from "bridge-sdk";

const bridge = await Bridge.init({
  l1Url: "https://api.minascan.io/node/devnet/v1/graphql",
  l1ArchiveUrl: "https://api.minascan.io/archive/devnet/v1/graphql",
  zekoUrl: "https://testnet.zeko.io/graphql",
  l1Network: "testnet",
  l2Network: "testnet",
});

Submit a Deposit

import { PrivateKey, UInt32, UInt64 } from "o1js";

const signer = PrivateKey.fromBase58(process.env.MINA_PRIVATE_KEY);
const recipient = signer.toPublicKey();

const txn = await bridge.submitDeposit(
  { sender: recipient, fee: 0.1 * 10e8 },
  {
    recipient,
    amount: UInt64.from(10 * 10e8),
    timeout: UInt32.MAXINT(),
    holderAccountL1: bridge.outerHolders[0],
  }
);

const result = await txn.sign([signer]).send();

Submit a Withdrawal

const txn = await bridge.submitWithdrawal(
  { sender: recipient, fee: 0.1 * 10e8 },
  {
    recipient,
    amount: UInt64.from(5 * 10e8),
  }
);

const result = await txn.sign([signer]).send();

Finalize Operations

// Finalize a deposit
await bridge.finalizeDeposit(recipient);

// Finalize a withdrawal
await bridge.finalizeWithdrawal(
  recipient,
  { sender: recipient, fee: 0.1 * 10e8 },
  bridge.outerHolders[0]
);
