What you need to know

AVAX input identity and handling

Avalanche is classified as a native asset for this route. AVAX uses a network-specific contract asset on Linea. The recorded Linea representation uses 18 decimal places. On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead.

Linea to zkSync Era L2 handoff

This route crosses two L2 execution environments. Linea settles to ethereum, while zkSync Era settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.

WBTC wrapped-token output check

WBTC is a custodial tokenized Bitcoin representation on smart-contract networks. Its transfers use token contracts and approvals rather than native Bitcoin inputs and outputs. On this route WBTC is the destination token on zkSync Era. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

zkSync Era destination 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.

WBTC output identity and receiving

Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on zkSync Era. The recorded zkSync Era representation uses 8 decimal places. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.

Linea source execution

Linea is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Linea. EVM 0x account address A Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones.

EVM-to-EVM execution boundary

Linea and zkSync Era can use the same 0x address syntax, but they are separate networks with different chain identifiers, gas balances, token contracts, and transaction histories. The recorded settlement context includes ethereum, so L1 and L2 confirmation behavior should not be assumed identical.

Mistakes specific to AVAX Linea to WBTC zkSync Era

Route-specific mistakes include sending on a network other than Linea; using a destination that is not valid for zkSync Era; running out of ETH before the source transaction is submitted; treating a wrapped token as the native gas asset. A Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones. On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.

Private Route for AVAX → WBTC

Linea wallet, token-transfer, contract, log, and gas activity remain public, and zkSync Era wallet, token-transfer, contract, log, and gas activity remain public. For this AVAX on Linea to WBTC on zkSync Era path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side EVM 0x account address; it does not hide either chain's public records.
