What exactly leaves zkSync Era as USDT?
USDT is a contract representation on zkSync Era with 6 decimals at 0x493257fD37EDB34451f62EDf8D2a0C418852bA4C. ETH, not USDT, pays gas unless both symbols are the same. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. 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 Polygon as SOL?
SOL is a contract representation on Polygon with 9 decimals at 0xd93f7E271cB87c23AaA73edC008A79646d1F9912. POL, not SOL, 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. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
Why does the USDT to SOL 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, Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
What changes between the source and destination asset roles?
USDT is the deposited stablecoin input; SOL is the quoted native-asset 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 zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
Which stablecoin contract must this route match?
USDT must match its zkSync Era representation. A ticker or target price is not enough to identify a token contract.
What funds the zkSync Era source transaction?
ETH is the native gas asset for zkSync Era. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. USDT is token-tracked and can need approval before transfer.
Can I swap USDT on zkSync to SOL on Polygon without KYC?
Requirements are checked for the live USDT zkSync to SOL 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.
