What you need to know

Move from a Solana account into Polygon EVM

Solana uses Solana accounts and SOL for source fees, while Polygon uses an EVM 0x account and POL for destination gas. Confirm the destination token contract and do not paste a Solana address into the EVM destination field. ETH is read from its Solana mint or native account, while WETH arrives at the quoted Polygon native or contract representation.

ETH mint and SOL fee checks

Base58-encoded Solana account address SOL is the native gas asset for Solana. A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. 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. The mint/account selected by the quote must match the source wallet balance.

Polygon contract and 0x receiving checks

EVM 0x account address POL is the native gas asset for Polygon. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas. A Solana address cannot receive this EVM-side output.

WETH wrapped-token output check

WETH is a contract wrapper for ETH. It can be transferred as a token but cannot replace the native gas balance required by the network. On this route WETH is the destination token on Polygon. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Mistakes specific to ETH Solana to WETH Polygon

Route-specific mistakes include sending on a network other than Solana; using a destination that is not valid for Polygon; running out of SOL before the source transaction is submitted; assuming solana and evm addresses are interchangeable; treating a wrapped token as the native gas asset. A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. 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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

ETH input identity and handling

Ethereum is classified as a native asset for this route. ETH uses a network-specific contract asset on Solana. The recorded Solana representation uses 8 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.

WETH output identity and receiving

WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Polygon. The recorded Polygon representation uses 18 decimal places. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

Private Route for ETH → WETH

Solana account, token, program, signature, and fee activity remain public, and Polygon wallet, token-transfer, contract, log, and gas activity remain public. For this ETH on Solana to WETH on Polygon path, Private Route is intended to reduce the direct visible relationship between activity around the source-side Base58-encoded Solana account address and destination-side EVM 0x account address; it does not hide either chain's public records.

Swap ETH on Solana to WETH on Polygon FAQs

Can a Solana address be used for the Polygon output?

No. EVM 0x account address The WETH output belongs to the quoted EVM representation.

What pays gas on each side of this Solana-to-EVM route?

SOL pays source fees on Solana. POL pays later transactions on Polygon; the delivered WETH does not replace that gas balance unless it is the native asset.

What exactly leaves Solana as ETH?

ETH is a contract representation on Solana with 8 decimals at 7vfCXTUXx5WJV5JADk17DUJ4ksgau7utNKj4b963voxs. SOL, not ETH, pays gas unless both symbols are the same. A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. 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 WETH?

WETH is a contract representation on Polygon with 18 decimals at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. POL, not WETH, 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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

Why does the ETH to WETH 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, WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

What changes between the source and destination asset roles?

ETH is the deposited native-asset input; WETH 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 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 Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

Can I swap ETH on Solana to WETH on Polygon without KYC?

Requirements are checked for the live ETH Solana to WETH 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.
