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 WBTC representation leaves Tron?
WBTC is a contract representation on Tron with 8 decimals at TYhWwKpw43ENFWBTGpzLHn3882f2au7SMi. TRX, not WBTC, 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. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.
What WBTC representation arrives on Arbitrum?
WBTC is a contract representation on Arbitrum with 8 decimals at 0x2f2a2543B76A4166549F7aaB2e75Bef0aefC5B0f. ETH, not WBTC, pays gas unless both symbols are the same. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.
Does the same WBTC ticker guarantee the same ledger form?
No. This bridge keeps the asset intent while moving between a WBTC wrapped token and a WBTC 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 Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. 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 Arbitrum can prevent normal detection or receipt.
Can I bridge WBTC from Tron to Arbitrum without KYC?
Requirements are checked for the live WBTC Tron to Arbitrum 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.
