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 BNB Chain. The recorded BNB Chain 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 BNB Chain L1 into zkSync Era L2

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

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.

LINK output identity and receiving

Chainlink is classified as a governance or utility token for this route. LINK uses a network-specific contract asset on zkSync Era. The zkSync Era side is contract-tracked rather than a native gas balance. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.

BNB Chain source execution

BNB Chain is a L1 EVM network in the BNB Chain ecosystem. BNB pays source-side network gas on BNB Chain. EVM 0x account address A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20.

EVM-to-EVM execution boundary

BNB Chain 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 BNB Chain to LINK zkSync Era

Route-specific mistakes include sending on a network other than BNB Chain; using a destination that is not valid for zkSync Era; running out of BNB before the source transaction is submitted. A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. 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. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.

Private Route for AVAX → LINK

BNB Chain 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 BNB Chain to LINK 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.

Swap AVAX on BNB Chain to LINK on zkSync Era FAQs

What exactly leaves BNB Chain as AVAX?

AVAX is a contract representation on BNB Chain with 18 decimals at 0x1CE0c2827e2eF14D5C4f29a091d735A204794041. BNB, not AVAX, pays gas unless both symbols are the same. A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. 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.

What exactly arrives on zkSync Era as LINK?

LINK is a contract representation on zkSync Era at 0x52869bae3e091e36b0915941577f2d47d8d8b534. ETH, not LINK, pays gas unless both symbols are the same. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.

Why does the AVAX to LINK direction matter?

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. On receipt, LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.

What changes between the source and destination asset roles?

AVAX is the deposited native-asset input; LINK is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.

What should be matched before sending AVAX?

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 BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.

What funds the BNB Chain source transaction?

BNB is the native gas asset for BNB Chain. A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. AVAX is token-tracked and can need approval before transfer.

What is the most dangerous wrong-network mistake here?

Sending AVAX on a network other than BNB Chain, or using an address that is not valid for zkSync Era, can prevent detection or delivery. Match both network labels and representations to the active route.

Can I swap AVAX on BSC to LINK on zkSync without KYC?

Requirements are checked for the live AVAX BSC to LINK zkSync 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.
