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. USDT is read from its Solana mint or native account, while DAI arrives at the quoted Optimism native or contract representation.
USDT 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. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. 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. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path. A Solana address cannot receive this EVM-side output.
USDT and DAI: two stablecoin ledgers
USDT is issued through ERC-20, TRC-20, SPL, and other network-specific contracts. The ticker does not determine the token standard, contract, issuer controls, or destination address model. 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 route changes both asset identity and network representation; dollar-oriented pricing does not remove issuer controls, liquidity spread, contract, or receiving-network checks.
Mistakes specific to USDT Solana to DAI 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. A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. 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. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.
USDT input identity and handling
Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on Solana. The Solana side is contract-tracked rather than a native gas balance. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior.
DAI output identity and receiving
Dai is classified as a stablecoin for this route. DAI uses a network-specific contract asset on Optimism. The recorded Optimism representation uses 18 decimal places. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.
