Which side uses TRC-20 and TRX resources?
Tron is the Tron side. Match its Tron address and exact TRC-20 contract; the other network representation is separate.
What WETH representation leaves Tron?
WETH is a contract representation on Tron with 18 decimals at TXWkP3jLBqRGojUih1ShzNyDaN5Csnebok. TRX, not WETH, pays gas unless both symbols are the same. A Tron source uses a T-address plus bandwidth and energy accounting; TRX covers resource or fee needs for native or TRC-20 transfer execution. 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 WETH representation arrives on Optimism?
WETH is a contract representation on Optimism with 18 decimals at 0x4200000000000000000000000000000000000006. ETH, not WETH, 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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
Does the same WETH ticker guarantee the same ledger form?
No. This bridge keeps the asset intent while moving between a WETH wrapped token and a WETH wrapped token. Match the source and output details in the live quote.
Which gas balances matter for this bridge?
A Tron source uses a T-address plus bandwidth and energy accounting; TRX covers resource or fee needs for native or TRC-20 transfer execution. 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. The bridge output does not automatically fund every later gas need.
What destination address should be used?
EVM 0x account address Do not substitute a Tron address merely because a wallet displays both networks.
What wrong-direction mistake can prevent delivery?
Sending on a network other than Tron, selecting a representation not listed by the quote, or entering an address invalid for Optimism can prevent normal detection or receipt.
Can I bridge WETH from Tron to Optimism without KYC?
Requirements are checked for the live WETH Tron to Optimism 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.
