How the Sasquatch deposit route works

1. Select the source

Choose the WBTC asset and Scroll network you currently hold.

2. Review the route

Check the estimated output, fees, timing, and Polygon 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

WBTC source representation

Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Scroll. The recorded Scroll representation uses 8 decimal places. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.

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.

WBTC destination representation

Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Polygon. The recorded Polygon 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 receipt-side 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.

Scroll deposit-side 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.

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

Scroll to Polygon bridge mistakes

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; treating a wrapped token as the native gas asset. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. 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 WBTC → WBTC

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 WBTC on Scroll to WBTC 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.

Scroll to Polygon FAQs

What WBTC representation leaves Scroll?

WBTC is a contract representation on Scroll with 8 decimals at 0x3C1BCa5a656e69edCD0D4E36BEbb3FcDAcA60Cf1. ETH, not WBTC, pays gas unless both symbols are the same. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.

What WBTC representation arrives on Polygon?

WBTC is a contract representation on Polygon with 8 decimals at 0x1BFD67037B42Cf73acF2047067bd4F2C47D9BfD6. POL, not WBTC, 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. 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.

Does the same WBTC ticker guarantee the same ledger form?

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

Which gas balances matter for this bridge?

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. 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 Scroll address merely because a wallet displays both networks.

What wrong-direction mistake can prevent delivery?

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

Can I bridge WBTC from Scroll to Polygon without KYC?

Requirements are checked for the live WBTC Scroll to 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.
