What you need to know

WBTC input identity and handling

Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Avalanche. The recorded Avalanche 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.

Receiving stablecoin DAI

DAI is a crypto-backed dollar-oriented stablecoin whose canonical and bridged contracts vary by network. Its peg design does not make two network representations interchangeable. The destination wallet must support the exact Polygon representation. The route converts a wrapped-asset source into a stablecoin balance; the destination ticker alone is not a contract check.

DAI output identity and receiving

Dai is classified as a stablecoin for this route. DAI uses a network-specific contract asset on Polygon. The recorded Polygon representation uses 18 decimal places. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.

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.

Avalanche source execution

Avalanche is a L1 EVM network in the Avalanche ecosystem. AVAX pays source-side network gas on Avalanche. EVM 0x account address An Avalanche source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits.

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 Avalanche. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Mistakes specific to WBTC Avalanche to DAI Polygon

Route-specific mistakes include sending on a network other than Avalanche; using a destination that is not valid for Polygon; running out of AVAX before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract; treating a wrapped token as the native gas asset. An Avalanche source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits. 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. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.

Private Route for WBTC → DAI

Avalanche 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 Avalanche to DAI 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 WBTC on Avalanche to DAI on Polygon FAQs

What exactly leaves Avalanche as WBTC?

WBTC is a contract representation on Avalanche with 8 decimals at 0x50b7545627a5162F82A992c33b87aDc75187B218. AVAX, not WBTC, pays gas unless both symbols are the same. An Avalanche source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.

What exactly arrives on Polygon as DAI?

DAI is a contract representation on Polygon with 18 decimals at 0x8f3Cf7ad23Cd3CaDbD9735AFf958023239c6A063. POL, not DAI, 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. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.

Why does the WBTC to DAI direction matter?

WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. On receipt, The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.

What changes between the source and destination asset roles?

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

What should be matched before sending WBTC?

WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. An Avalanche source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.

Which stablecoin contract must this route match?

DAI must match the quoted Polygon representation. A ticker or target price is not enough to identify a token contract.

Can the wrapped asset pay native network gas?

No. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. An Avalanche source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas.

Can I swap WBTC on Avalanche to DAI on Polygon without KYC?

Requirements are checked for the live WBTC Avalanche to DAI 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.
