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.

SOL to WETH representation change

Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas. Verify the exact TRC-20 contract and the Arbitrum representation independently.

WETH wrapped-token output check

WETH is a contract wrapper for ETH. It can be transferred as a token but cannot replace the native gas balance required by the network. On this route WETH is the destination token on Tron. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Mistakes specific to SOL Arbitrum to WETH Tron

Route-specific mistakes include sending on a network other than Arbitrum; using a destination that is not valid for Tron; running out of ETH before the source transaction is submitted; assuming evm and other addresses are interchangeable; treating a wrapped token as the native gas asset. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead. 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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

SOL input identity and handling

Solana is classified as a native asset for this route. SOL uses a network-specific contract asset on Arbitrum. The recorded Arbitrum representation uses 9 decimal places. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead.

WETH output identity and receiving

WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Tron. The recorded Tron representation uses 18 decimal places. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

Private Route for SOL → WETH

Arbitrum wallet, token-transfer, contract, log, and gas activity remain public, and Tron address, token-transfer, contract, and resource activity remain public. For this SOL on Arbitrum to WETH 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.
