Is the WETH or ARB side TRC-20?
The Tron side must match the TRC-20 contract or native TRX label shown in the route. The Ethereum side is a separate network representation.
What exactly leaves Tron as WETH?
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 exactly arrives on Ethereum as ARB?
ARB is a contract representation on Ethereum at 0xb50721bcf8d664c30412cfbc6cf7a15145234ad1. ETH, not ARB, pays gas unless both symbols are the same. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
Why does the WETH to ARB direction matter?
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. On receipt, A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
What changes between the source and destination asset roles?
WETH is the deposited token input; ARB 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 WETH?
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. 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 Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
Can the wrapped asset pay native network gas?
No. 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. 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 Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract.
Can I swap WETH on Tron to ARB on Ethereum without KYC?
Requirements are checked for the live WETH Tron to ARB Ethereum 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.
