Buy zkSync (ZK)
Buy ZK instantly with credit card, Apple Pay, or bank transfer. Just type "Buy ZK" and ChainATM's AI handles the rest, straight into your self-custody wallet.
What is zkSync?
zkSync (ZK) is an Ethereum L2 using zero-knowledge proofs for cheaper, faster transactions while inheriting Ethereum security. Buying ZK gives you direct exposure to that, held in a wallet only you control.
How buying ZK works
Buying zkSync through ChainATM is one instruction: say "Buy €100 of ZK" and the AI handles the on-ramp, the routing, and delivery to your wallet. Payment goes through the Coinbase-powered on-ramp — card, Apple Pay, Google Pay, or SEPA transfer — with KYC done once at Coinbase rather than on every purchase.
What to weigh before buying ZK
- Layer-2 tokens depend on their rollup attracting real activity away from the base chain. They inherit the base layer's security while competing with every other rollup for users.
- ZK settles on zkSync Era, so you will need a small amount of zkSync Era gas to move or swap it afterwards. ChainATM accounts for this when it quotes the purchase.
- Crypto bought through ChainATM lands in your own wallet, not an exchange balance. That means no withdrawal step and no counterparty holding your funds — and equally, that the seed phrase is yours to protect.
