Move from a Solana account into Base EVM

Solana uses Solana accounts and SOL for source fees, while Base 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. ETH is read from its Solana mint or native account, while SOL arrives at the quoted Base native or contract representation.

ETH 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. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. The mint/account selected by the quote must match the source wallet balance.

Base contract and 0x receiving checks

EVM 0x account address ETH is the native gas asset for Base. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native. A Solana address cannot receive this EVM-side output.

Mistakes specific to ETH Solana to SOL Base

Route-specific mistakes include sending on a network other than Solana; using a destination that is not valid for Base; running out of SOL before the source transaction is submitted; assuming solana and evm addresses are interchangeable. A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

ETH input identity and handling

Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.

SOL output identity and receiving

Solana is classified as a native asset for this route. SOL uses a network-specific contract asset on Base. The recorded Base representation uses 9 decimal places. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

Private Route for ETH → SOL

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