What WBTC representation leaves Arbitrum?
WBTC is a contract representation on Arbitrum with 8 decimals at 0x2f2a2543B76A4166549F7aaB2e75Bef0aefC5B0f. ETH, not WBTC, pays gas unless both symbols are the same. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. 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 Avalanche?
WBTC is a contract representation on Avalanche with 8 decimals at 0x50b7545627a5162F82A992c33b87aDc75187B218. AVAX, not WBTC, pays gas unless both symbols are the same. An Avalanche destination must be a C-Chain-compatible account; native AVAX can fund later C-Chain gas, while token receipt uses the quoted C-Chain contract. 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?
On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. An Avalanche destination must be a C-Chain-compatible account; native AVAX can fund later C-Chain gas, while token receipt uses the quoted C-Chain contract. 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 Arbitrum address merely because a wallet displays both networks.
What wrong-direction mistake can prevent delivery?
Sending on a network other than Arbitrum, selecting a representation not listed by the quote, or entering an address invalid for Avalanche can prevent normal detection or receipt.
Can I bridge WBTC from Arbitrum to Avalanche without KYC?
Requirements are checked for the live WBTC Arbitrum to Avalanche 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.
