What you need to know

Convert the Arbitrum 0x input into a Solana-account receipt

Arbitrum uses EVM account addresses and ETH for source gas. Solana uses Solana accounts, transaction signatures, and SOL for destination activity. A 0x address is not a valid substitute for the Solana receiving address shown by the route. USDC uses USDC contract token on the source; WETH uses WETH wrapped token on Solana.

Solana token-account check for WETH

Base58-encoded Solana account address A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas. A compatible wallet may create or use an associated token account, and SOL—not WETH unless it is SOL—pays later Solana fees.

Arbitrum approval and gas before the handoff

ETH is the native gas asset for Arbitrum. USDC is contract-tracked and can require an allowance before transfer. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval.

Converting stablecoin USDC into WETH

USDC is an issued dollar-oriented stablecoin with canonical, native, and bridged variants across networks. Contract events and issuer controls differ from a network-native gas asset. The source is a stablecoin contract or recorded native representation, while WETH is classified as token. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.

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 Solana. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Mistakes specific to USDC Arbitrum to WETH Solana

Route-specific mistakes include sending on a network other than Arbitrum; using a destination that is not valid for Solana; running out of ETH before the source transaction is submitted; assuming evm and solana addresses are interchangeable; selecting a stablecoin by ticker without checking its network contract; 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. The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

USDC input identity and handling

USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on Arbitrum. The Arbitrum side is contract-tracked rather than a native gas balance. The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset.

WETH output identity and receiving

WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Solana. The recorded Solana representation uses 9 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 USDC → WETH

Arbitrum wallet, token-transfer, contract, log, and gas activity remain public, and Solana account, token, program, signature, and fee activity remain public. For this USDC on Arbitrum to WETH on Solana path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side Base58-encoded Solana account address; it does not hide either chain's public records.
