How it works

From sign-in to first transaction in under 60 seconds.

  1. 01

    Sign in

    Use Google, X, Discord, Apple, GitHub or email. Sign-in only proves who you are — it can never move your funds.

  2. 02

    Choose your signer

    Create a passkey with Face ID or Touch ID, generate a recovery phrase, or connect a wallet you already use.

  3. 03

    Transact

    Your smart account works on 6 networks, with $5 of gas already loaded.

Under the hood

Serious security. Zero ceremony.

NYKNYC is built on open standards and battle-tested building blocks, so the simple experience never comes at the cost of control.

Your keys stay yours

Social login only identifies you. Every transaction must be signed by a signer you control — NYKNYC can't move or freeze your funds.

FAQ

Questions, answered.

Is NYKNYC custodial?

No. Your wallet is an ERC-4337 smart account onchain, controlled by the signers you choose — a passkey, a recovery phrase or a wallet you already own. NYKNYC never has access to your funds and can't freeze your account.

If it's self-custodial, why do I sign in with Google?

Signing in with Google, X, Discord, Apple, GitHub or email only identifies you and keeps your wallets and settings in one place. Moving funds always requires a signature from a signer you control.

Do I need a seed phrase?

No. A passkey lets you sign with Face ID, Touch ID or Windows Hello. If you prefer, you can generate or import a BIP-39 recovery phrase, or connect MetaMask, WalletConnect and other wallets as signers.

What is the $5 of free gas?

Every new account gets $5 in gas credits. Fees are paid from one USD balance on every supported network, so you don't need ETH, BNB or POL to make your first transaction.

Which networks are supported?

Ethereum, Arbitrum One, BNB Smart Chain, OP Mainnet, Polygon, Base. More networks are on the way.

Can I use NYKNYC inside Telegram?

Yes. NYKNYC also runs as a Telegram mini app, with the same smart wallet.

I'm a developer. What does it cost to integrate?

The wagmi connector is open source and free to use. Register your app to get an App ID, add the connector, and optionally sponsor gas for your users.
