How to Buy Crypto Without KYC

Mar 8, 2026

Most centralised exchanges require identity verification (KYC — Know Your Customer) before you can buy, sell, or withdraw crypto. For on-chain swaps between existing crypto assets, KYC is not required. Non-custodial protocols like Relay let you swap any supported token for any other token with nothing but a wallet connection.

Why Onchain Swaps Don't Require KYC

KYC requirements exist on centralised exchanges because they operate as financial intermediaries — they hold your funds, convert between fiat and crypto, and are subject to financial regulations that require identity verification.

Onchain protocols are different. They are smart contract infrastructure — code deployed on a blockchain that executes user transactions directly. No company holds your funds; no intermediary processes your swap. The protocol coordinates execution between the user and a network of fillers, but at no point does any entity take custody of your assets.

Because there's no financial intermediary and no fiat on-ramp, there's no KYC requirement. You connect a wallet and go.

What "No KYC" Means in Practice

• No account creation. You don't create a profile or enter an email address.
• No identity documents. No passport, driver's licence, or selfie.
• No wait times. No verification queue. Connect your wallet and start immediately.
• No withdrawal limits. On-chain protocols don't impose exchange-style withdrawal limits.

This applies to swapping existing crypto assets between tokens and chains. It does not apply to buying crypto with fiat currency — that requires an on-ramp service, which typically does require KYC.

How to Swap Without KYC Using Relay

Step 1: Go to Relay

Open relay.link in your browser.

Step 2: Connect your wallet

Connect any compatible wallet — MetaMask, Rainbow, Coinbase Wallet for EVM, or Phantom/Backpack for Solana. No email or account is created.

Step 3: Set your swap

Choose what you're starting with and what you want to receive. Select the destination chain.

Step 4: Confirm and receive

Confirm the transaction in your wallet. Relay's filler network delivers the output directly to your wallet in seconds.

Non-Custodial vs Custodial: What's the Difference?

Custodial (centralised exchanges): The exchange holds your funds. You have an account. To move funds, you withdraw to an external wallet. KYC is required to comply with financial regulations.

Non-custodial (Relay and onchain protocols): You hold your own funds in your own wallet. The protocol executes swaps atomically — assets go from your wallet to your wallet without any intermediary holding them in between. No KYC because there's no financial intermediary.

The trade-off: non-custodial protocols require you to manage your own private keys and wallet security. If you lose access to your wallet, the protocol cannot recover your funds.

Starting From Zero

If you have no crypto at all, a centralised exchange or fiat on-ramp is still the starting point. These services convert fiat currency (bank transfer, card) into crypto and do require KYC because they handle fiat money.

Once you have any crypto in a self-custodial wallet, onchain protocols like Relay handle all subsequent swaps without KYC.

Frequently Asked Questions

Is swapping without KYC legal?

Onchain swaps between crypto assets are generally legal in most jurisdictions. Regulations vary by country and change over time. For tax and compliance questions, consult a professional adviser.

Does Relay store any of my data?

Relay coordinates on-chain execution — the protocol doesn't store personal data. All transactions are recorded on the respective blockchains, which are public ledgers.

What wallet do I need?

Any self-custodial wallet: MetaMask, Rainbow, Coinbase Wallet, Phantom, Backpack, or any WalletConnect-compatible wallet.

Can I buy crypto from a bank account on Relay?

No. Relay works with on-chain balances only. For fiat-to-crypto, use a separate on-ramp service.
