Is the WBTC or LINK side TRC-20?
The Tron side must match the TRC-20 contract or native TRX label shown in the route. The zkSync Era side is a separate network representation.
What exactly leaves Tron as WBTC?
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 exactly arrives on zkSync Era as LINK?
LINK is a contract representation on zkSync Era at 0x52869bae3e091e36b0915941577f2d47d8d8b534. ETH, not LINK, pays gas unless both symbols are the same. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
Why does the WBTC to LINK 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, LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
What changes between the source and destination asset roles?
WBTC is the deposited wrapped-asset input; LINK is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
