What exactly leaves Ethereum as WETH?
WETH is a contract representation on Ethereum with 18 decimals at 0xb1A7F8b3AdA1Cbd7752c1306725b07D2F8B4e726. ETH, not WETH, pays gas unless both symbols are the same. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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 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 WETH to DAI direction matter?
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. 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?
WETH is the deposited token 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 WETH?
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. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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. 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. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas.
Can I swap WETH on Ethereum to DAI on Polygon without KYC?
Requirements are checked for the live WETH Ethereum 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.
