What exactly leaves Ethereum as USDT?
USDT is a contract representation on Ethereum at 0xdac17f958d2ee523a2206206994597c13d831ec7. ETH, not USDT, 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. 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 WETH?
WETH is a contract representation on zkSync Era with 18 decimals at 0x5AEa5775959fBC2557Cc8789bC1bf90A239D9a91. ETH, not WETH, 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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
Why does the USDT to WETH 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, WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
