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 Polygon. The recorded Polygon 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 Polygon L1 into Linea L2

Polygon source execution occurs on L1, while Linea delivery occurs on a separate L2 ledger that settles to ethereum. POL 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 Linea. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Linea destination execution

Linea is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Linea. EVM 0x account address A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract.

WBTC output identity and receiving

Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Linea. The recorded Linea 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.

Polygon source execution

Polygon is a L1 EVM network in the Polygon ecosystem. POL pays source-side network gas on Polygon. EVM 0x account address A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1.

EVM-to-EVM execution boundary

Polygon and Linea 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 Polygon to WBTC Linea

Route-specific mistakes include sending on a network other than Polygon; using a destination that is not valid for Linea; running out of POL before the source transaction is submitted; treating a wrapped token as the native gas asset. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. 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 Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. 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

Polygon wallet, token-transfer, contract, log, and gas activity remain public, and Linea wallet, token-transfer, contract, log, and gas activity remain public. For this AVAX on Polygon to WBTC on Linea 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 Polygon to WBTC on Linea FAQs

What exactly leaves Polygon as AVAX?

AVAX is a contract representation on Polygon with 18 decimals at 0x2C89bbc92BD86F8075d1DEcc58C7F4E0107f286b. POL, not AVAX, pays gas unless both symbols are the same. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. 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 Linea as WBTC?

WBTC is a contract representation on Linea with 8 decimals at 0x3aAB2285ddcDdaD8edf438C1bAB47e1a9D05a9b4. ETH, not WBTC, pays gas unless both symbols are the same. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. 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.

Why does the AVAX to WBTC 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, 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.

What changes between the source and destination asset roles?

AVAX is the deposited native-asset input; WBTC is the quoted wrapped-asset 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 Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. 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.

Can the wrapped asset pay native network gas?

No. 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. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract.

What funds the Polygon source transaction?

POL is the native gas asset for Polygon. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. AVAX is token-tracked and can need approval before transfer.

Can I swap AVAX on Polygon to WBTC on Linea without KYC?

Requirements are checked for the live AVAX Polygon to WBTC Linea 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.
