Is the WBTC or BTC side TRC-20?
The Tron side must match the TRC-20 contract or native TRX label shown in the route. The Avalanche side is a separate network representation.
What exactly leaves Avalanche as WBTC?
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 source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.
What exactly arrives on Tron as BTC?
BTC is a contract representation on Tron with 8 decimals at TN3W4H6rK2ce4vX9YnFQHwKENnHjoxb3m9. TRX, not BTC, pays gas unless both symbols are the same. A Tron receipt belongs to a T-address as native TRX or the quoted TRC-20 contract; later activity consumes Tron resources or TRX fees. Native BTC must arrive at a provider-accepted Bitcoin address and becomes a UTXO after broadcast; an EVM address is not a native BTC destination.
Why does the WBTC to BTC direction matter?
WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. On receipt, Native BTC must arrive at a provider-accepted Bitcoin address and becomes a UTXO after broadcast; an EVM address is not a native BTC destination.
What changes between the source and destination asset roles?
WBTC is the deposited wrapped-asset input; BTC is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
What should be matched before sending WBTC?
