What you need to know

Bitcoin UTXO and account-chain boundary

Bitcoin uses a UTXO source model while zkSync Era uses a non-UTXO destination model. Native Bitcoin deposits require a supported Bitcoin address, confirmation-aware input handling, and attention to change outputs; an EVM token labeled BTC or WBTC is not native BTC.

zkSync Era receipt-side execution

zkSync Era is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on zkSync Era. EVM 0x account address A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery.

Bitcoin deposit-side execution

Bitcoin is a L1 Bitcoin Script network in the Bitcoin ecosystem. BTC pays source-side network gas on Bitcoin. Native Bitcoin address supported by the route, including network-specific bech32 or legacy formats A Bitcoin source spends UTXOs, creates a fee-bearing transaction and possible change, and waits for the route provider’s confirmation depth.

From Bitcoin L1 into zkSync Era L2

Bitcoin source execution occurs on L1, while zkSync Era delivery occurs on a separate L2 ledger that settles to ethereum. BTC pays source gas and ETH is the destination gas asset; identical-looking wallet addresses do not merge the balances or transaction histories.

Choose an asset that exists on both route sides

The live quote lists the exact Bitcoin input asset and zkSync Era output representation. A shared ticker is not proof of a shared contract, native ledger, decimals, or wallet support.

Bitcoin to zkSync Era bridge mistakes

Route-specific mistakes include sending on a network other than Bitcoin; using a destination that is not valid for zkSync Era; running out of BTC before the source transaction is submitted; assuming bitcoin and evm addresses are interchangeable. A Bitcoin source spends UTXOs, creates a fee-bearing transaction and possible change, and waits for the route provider’s confirmation depth. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery.

Private Route for BTC → BNB

Bitcoin UTXO inputs, outputs, change, and confirmation history remain public, and ZKsync Era wallet, token-transfer, contract, log, and gas activity remain public. For this BTC on Bitcoin to BNB on ZKsync Era path, Private Route is intended to reduce the direct visible relationship between activity around the source-side Native Bitcoin address supported by the route, including network-specific bech32 or legacy formats and destination-side EVM 0x account address; it does not hide either chain's public records.

Bitcoin to ZKsync Era FAQs

Where is native Bitcoin used in this bridge direction?

Bitcoin is the UTXO source and BTC fees apply before the provider credits zkSync Era. Tokenized BTC on an account chain is not the same ledger asset.

Which asset can travel from Bitcoin to zkSync Era?

The live route lists assets supported in this direction. Confirm that the selected source representation has an explicit zkSync Era output before depositing.

Which gas balances matter for this bridge?

A Bitcoin source spends UTXOs, creates a fee-bearing transaction and possible change, and waits for the route provider’s confirmation depth. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. The bridge output does not automatically fund every later gas need.

What destination address should be used?

EVM 0x account address Do not substitute a Bitcoin address merely because a wallet displays both networks.

What wrong-direction mistake can prevent delivery?

Sending on a network other than Bitcoin, selecting a representation not listed by the quote, or entering an address invalid for zkSync Era can prevent normal detection or receipt.

Can I bridge BTC from Bitcoin to ZKsync Era without KYC?

Requirements are checked for the live BTC Bitcoin to ZKsync Era quote. Verification requirements can depend on the provider, amount, jurisdiction, and current route. Sasquatch does not verify this route as universally no-KYC; check the live flow before continuing.
