Arbitrum to Tron: TRC-20 and EVM boundary

On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. 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. Arbitrum and Tron 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.

ARB to WBTC representation change

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. Verify the exact TRC-20 contract and the Arbitrum representation independently.

WBTC wrapped-token output 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 destination token on Tron. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

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.

For this ARB on Arbitrum to WBTC on Tron path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side Tron Base58Check address, commonly beginning with T; it does not hide either chain's public records.
