What you need to know

SOL input identity and handling

Solana is classified as a native asset for this route. SOL uses a network-specific contract asset on BNB Chain. The recorded BNB Chain representation uses 18 decimal places. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead.

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.

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.

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.

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 Polygon can use the same 0x address syntax, but they are separate networks with different chain identifiers, gas balances, token contracts, and transaction histories.

Mistakes specific to SOL BNB Chain to WETH Polygon

Route-specific mistakes include sending on a network other than BNB Chain; using a destination that is not valid for Polygon; running out of BNB before the source transaction is submitted; treating a wrapped token as the native gas asset. 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. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead. 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.

Private Route for SOL → WETH

BNB Chain wallet, token-transfer, contract, log, and gas activity remain public, and Polygon wallet, token-transfer, contract, log, and gas activity remain public. For this SOL on BNB Chain to WETH 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 SOL on BNB Chain to WETH on Polygon FAQs

What exactly leaves BNB Chain as SOL?

SOL is a contract representation on BNB Chain with 18 decimals at 0x570A5D26f7765Ecb712C0924E4De545B89fD43dF. BNB, not SOL, 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. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead.

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 SOL to WETH direction matter?

Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead. 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?

SOL 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 SOL?

Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract 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 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 the wrapped asset pay native network gas?

No. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas. 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 Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas.

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. SOL is token-tracked and can need approval before transfer.

Can I swap SOL on BSC to WETH on Polygon without KYC?

Requirements are checked for the live SOL BSC 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.
