What exactly leaves Optimism as DAI?
DAI is a contract representation on Optimism with 18 decimals at 0xDA10009cBd5D07dd0CeCc66161FC93D7c9000da1. ETH, not DAI, pays gas unless both symbols are the same. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical.
What exactly arrives on Optimism as USDT?
USDT is a contract representation on Optimism with 6 decimals at 0x94b008aA00579c1307B0EF2c499aD98a8ce58e58. ETH, not USDT, pays gas unless both symbols are the same. An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.
Why does the DAI to USDT direction matter?
DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. On receipt, Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.
What changes between the source and destination asset roles?
DAI is the deposited stablecoin input; USDT 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 DAI?
DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.
Which stablecoin contract must this route match?
DAI must match its Optimism representation. USDT must match the quoted Optimism representation. A ticker or target price is not enough to identify a token contract.
What funds the Optimism source transaction?
ETH is the native gas asset for Optimism. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. DAI is token-tracked and can need approval before transfer.
Can I swap DAI on OP Mainnet to USDT on OP Mainnet without KYC?
Requirements are checked for the live DAI OP Mainnet to USDT OP Mainnet 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.
