Tron to zkSync Era: TRC-20 and EVM boundary

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. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. Tron and zkSync Era use different network identities, gas assets, wallet support, confirmation behavior, and destination conventions. Validate each side independently in the current route.

TRX resources and Tron address check

TRX is the native gas asset for Tron. Tron Base58Check address, commonly beginning with T A TRC-20 token transfer is not an ERC-20 transfer even when an asset ticker exists on both sides.

WBTC to USDT representation change

WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another. Verify the exact TRC-20 contract and the zkSync Era representation independently.

Receiving stablecoin USDT

USDT is issued through ERC-20, TRC-20, SPL, and other network-specific contracts. The ticker does not determine the token standard, contract, issuer controls, or destination address model. The destination wallet must support the exact zkSync Era representation. The route converts a wrapped-asset source into a stablecoin balance; the destination ticker alone is not a contract check.

WBTC unwrap or exchange input check

WBTC is a custodial tokenized Bitcoin representation on smart-contract networks. Its transfers use token contracts and approvals rather than native Bitcoin inputs and outputs. On this route WBTC is the source token on Tron. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
