What exactly leaves Polygon as USDT?
USDT is a contract representation on Polygon with 6 decimals at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. POL, not USDT, 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. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior.
What exactly arrives on zkSync Era as LINK?
LINK is a contract representation on zkSync Era at 0x52869bae3e091e36b0915941577f2d47d8d8b534. ETH, not LINK, pays gas unless both symbols are the same. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
Why does the USDT to LINK direction matter?
The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. On receipt, LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
What changes between the source and destination asset roles?
USDT is the deposited stablecoin input; LINK is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
What should be matched before sending USDT?
The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
Which stablecoin contract must this route match?
USDT must match its Polygon representation. A ticker or target price is not enough to identify a token contract.
What funds the Polygon source transaction?
POL is the native gas asset for Polygon. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. USDT is token-tracked and can need approval before transfer.
Can I swap USDT on Polygon to LINK on zkSync without KYC?
Requirements are checked for the live USDT Polygon to LINK zkSync 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.
