What you need to know

ETH input identity and handling

Ethereum is classified as a native asset for this route. ETH uses a native asset on Scroll. The recorded Scroll representation uses 18 decimal places. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.

Leaving Scroll L2 for Polygon L1

Scroll inclusion and its ethereum settlement are distinct from final receipt on Polygon. The live route, rather than a generic rollup withdrawal assumption, determines the provider path and timing for this direction.

Polygon destination execution

Polygon is a L1 EVM network in the Polygon ecosystem. POL pays destination-side network gas on Polygon. EVM 0x account address A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas.

AVAX output identity and receiving

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. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.

Scroll source execution

Scroll is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Scroll. EVM 0x account address A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently.

EVM-to-EVM execution boundary

Scroll and Polygon 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 ETH Scroll to AVAX Polygon

Route-specific mistakes include sending on a network other than Scroll; using a destination that is not valid for Polygon; running out of ETH before the source transaction is submitted. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.

Private Route for ETH → AVAX

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

What exactly leaves Scroll as ETH?

ETH is listed as the native representation on Scroll; ETH is used for network gas. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.

What exactly arrives on 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 receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.

Why does the ETH to AVAX direction matter?

Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. On receipt, Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.

What changes between the source and destination asset roles?

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

What should be matched before sending ETH?

Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.

What funds the Scroll source transaction?

ETH is the native gas asset for Scroll. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. ETH is recorded as native on this source.

What is the most dangerous wrong-network mistake here?

Sending ETH on a network other than Scroll, or using an address that is not valid for Polygon, can prevent detection or delivery. Match both network labels and representations to the active route.

Can I swap ETH on Scroll to AVAX on Polygon without KYC?

Requirements are checked for the live ETH Scroll to AVAX Polygon 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.
