How the Sasquatch deposit route works

1. Select the source

Choose the WETH asset and Optimism network you currently hold.

2. Review the route

Check the estimated output, fees, timing, and Solana destination network.

3. Create the order

Open the live route and follow the exact deposit instructions.

4. Track delivery

Use the receipt and status page until the destination funds arrive.

What you need to know

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

Optimism 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. WETH uses WETH wrapped 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.

Optimism approval and gas before the handoff

ETH is the native gas asset for Optimism. WETH is contract-tracked and can require an allowance before transfer. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay.

WETH keeps its ticker while changing ledgers

WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Optimism. The recorded Optimism representation uses 18 decimal places. The Optimism side is contract-tracked rather than a native gas balance. 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. The Solana side is contract-tracked rather than a native gas balance. WETH leaves as a wrapped contract asset. WETH arrives as a wrapped contract asset.

Optimism to Solana bridge mistakes

Route-specific mistakes include sending on a network other than Optimism; 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; treating a wrapped token as the native gas asset. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. 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. 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.

Private Route for WETH → WETH

Optimism wallet, token-transfer, contract, log, and gas activity remain public, and Solana account, token, program, signature, and fee activity remain public. For this WETH on Optimism 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.

Optimism to Solana FAQs

Can the Optimism 0x account be reused as the Solana destination?

No. Base58-encoded Solana account address ETH pays the EVM source transaction, while SOL is used for later Solana activity.

What WETH representation leaves Optimism?

WETH is a contract representation on Optimism with 18 decimals at 0x4200000000000000000000000000000000000006. ETH, not WETH, pays gas unless both symbols are the same. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. 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.

What WETH representation arrives on Solana?

WETH is a contract representation on Solana with 9 decimals at AaAEw2VCw1XzgvKB8Rj2DyK2ZVau9fbt2bE8hZFWsMyE. SOL, not WETH, pays gas unless both symbols are the same. 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.

Does the same WETH ticker guarantee the same ledger form?

No. This bridge keeps the asset intent while moving between a WETH wrapped token and a WETH wrapped token. Match the source and output details in the live quote.

Which gas balances matter for this bridge?

An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. The bridge output does not automatically fund every later gas need.

What destination address should be used?

Base58-encoded Solana account address Do not substitute a Optimism address merely because a wallet displays both networks.

What wrong-direction mistake can prevent delivery?

Sending on a network other than Optimism, selecting a representation not listed by the quote, or entering an address invalid for Solana can prevent normal detection or receipt.

Can I bridge WETH from Optimism to Solana without KYC?

Requirements are checked for the live WETH Optimism to Solana quote. Verification requirements can depend on the provider, amount, jurisdiction, and current route. Sasquatch does not verify this route as universally no-KYC; check the live flow before continuing.
