Tron to Solana: TRC-20 and SVM 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 Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. Tron and Solana 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.

WETH to AVAX representation change

WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance. Verify the exact TRC-20 contract and the Solana representation independently.

WETH unwrap or exchange input 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 source token on Tron. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Avalanche is classified as a native asset for this route. AVAX uses a network-specific contract asset on Solana. The recorded Solana representation uses 8 decimal places. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.

Private Route for WETH → AVAX

Tron address, token-transfer, contract, and resource activity remain public, and Solana account, token, program, signature, and fee activity remain public. For this WETH on Tron to AVAX on Solana path, Private Route is intended to reduce the direct visible relationship between activity around the source-side Tron Base58Check address, commonly beginning with T and destination-side Base58-encoded Solana account address; it does not hide either chain's public records.
