Noir Adapter Demo

Connect Noir Wallet to use Bridge write actions and Identity/MCA queries. Market read-only APIs work without a wallet.

Zcash MCA Bridge

Covers all createNoirCrossChainLendingBridge methods. Deposit targets must be transparent t1/t3 addresses.

Usage example

import { NoirZcashWalletAdapter } from '@rhea-finance/zcash-wallet-adapter';
import { createNoirCrossChainLendingBridge } from '@rhea-finance/zcash-wallet-adapter/lending';

const noir = new NoirZcashWalletAdapter({ network: 'mainnet' });
await noir.connect();

const lending = createNoirCrossChainLendingBridge(noir, {
  fundingSource: 'shielded',
  signingMode: 'derived',
});

isTransparentZcashLendingAddress

Validate Address

Usage example

import { isTransparentZcashLendingAddress } from '@rhea-finance/zcash-wallet-adapter/lending';

const valid = isTransparentZcashLendingAddress('t1...', 'zcash:mainnet');

// Lazy-load the full RHEA cross-chain SDK
const sdk = await lending.loadSdk();

Usage example

// Look up MCA bound to the connected Noir wallet
const mcaId = await lending.getMcaByWallet();
// null when no MCA exists yet

// Request a transparent deposit address for MCA creation
const depositAddress = await lending.getCreateMcaDepositAddress('multica.near');

Usage example

// Send ZEC from shielded balance to a RHEA deposit address
const result = await lending.sendDeposit({
