How the Sasquatch deposit route works

1. Select the source

Choose the WETH asset and Polygon network you currently hold.

2. Review the route

Check the estimated output, fees, timing, and BNB Chain destination network.

3. Create the order

Open the live route and follow the exact deposit instructions.

4. Track delivery

Use the receipt and status page until the destination funds arrive.

What you need to know

WETH source representation

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 leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer.

EVM-to-EVM execution boundary

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

WETH destination representation

WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on BNB Chain. The recorded BNB Chain 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 receipt-side execution

BNB Chain is a L1 EVM network in the BNB Chain ecosystem. BNB pays destination-side network gas on BNB Chain. EVM 0x account address A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas.

Polygon deposit-side 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.

WETH unwrap or exchange input 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 source token on Polygon. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Polygon to BNB Chain bridge mistakes

Route-specific mistakes include sending on a network other than Polygon; using a destination that is not valid for BNB Chain; 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. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB 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 WETH → WETH

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

Polygon to BNB Chain FAQs

What WETH representation leaves Polygon?

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 source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer.

What WETH representation arrives on BNB Chain?

WETH is a contract representation on BNB Chain with 18 decimals at 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. BNB, not WETH, pays gas unless both symbols are the same. A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

Does the same WETH ticker guarantee the same ledger form?

No. This bridge keeps the asset intent while moving between a WETH wrapped token and a WETH wrapped token. Match the source and output details in the live quote.

Which gas balances matter for this bridge?

A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. The bridge output does not automatically fund every later gas need.

What destination address should be used?

EVM 0x account address Do not substitute a Polygon address merely because a wallet displays both networks.

What wrong-direction mistake can prevent delivery?

Sending on a network other than Polygon, selecting a representation not listed by the quote, or entering an address invalid for BNB Chain can prevent normal detection or receipt.

Can I bridge WETH from Polygon to BNB Chain without KYC?

Requirements are checked for the live WETH Polygon to BNB Chain 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.
