AVAX input identity and handling
Avalanche is classified as a native asset for this route. AVAX uses a native asset on Avalanche. The recorded Avalanche 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.
From Avalanche L1 into zkSync Era L2
Avalanche source execution occurs on L1, while zkSync Era delivery occurs on a separate L2 ledger that settles to ethereum. AVAX pays source gas and ETH is the destination gas asset; identical-looking wallet addresses do not merge the balances or transaction histories.
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.
Avalanche source execution
Avalanche is a L1 EVM network in the Avalanche ecosystem. AVAX pays source-side network gas on Avalanche. EVM 0x account address An Avalanche source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits.
EVM-to-EVM execution boundary
Avalanche 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 Avalanche to WBTC zkSync Era
Route-specific mistakes include sending on a network other than Avalanche; using a destination that is not valid for zkSync Era; running out of AVAX before the source transaction is submitted; treating a wrapped token as the native gas asset. An Avalanche source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits. 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.
