Move from a Solana account into Optimism EVM
Solana uses Solana accounts and SOL for source fees, while Optimism uses an EVM 0x account and ETH for destination gas. Confirm the destination token contract and do not paste a Solana address into the EVM destination field. DAI is read from its Solana mint or native account, while WETH arrives at the quoted Optimism native or contract representation.
DAI mint and SOL fee checks
Base58-encoded Solana account address SOL is the native gas asset for Solana. A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. The mint/account selected by the quote must match the source wallet balance.
Optimism contract and 0x receiving checks
EVM 0x account address ETH is the native gas asset for Optimism. An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas. A Solana address cannot receive this EVM-side output.
Converting stablecoin DAI into WETH
DAI is a crypto-backed dollar-oriented stablecoin whose canonical and bridged contracts vary by network. Its peg design does not make two network representations interchangeable. 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 Optimism. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Mistakes specific to DAI Solana to WETH Optimism
Route-specific mistakes include sending on a network other than Solana; using a destination that is not valid for Optimism; running out of SOL before the source transaction is submitted; assuming solana and evm addresses are interchangeable; selecting a stablecoin by ticker without checking its network contract; treating a wrapped token as the native gas asset. A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
DAI input identity and handling
Dai is classified as a stablecoin for this route. DAI uses a network-specific contract asset on Solana. The recorded Solana representation uses 8 decimal places. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical.
WETH output identity and receiving
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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
