Base 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; AVAX uses AVAX contract token on Solana.
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. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance. A compatible wallet may create or use an associated token account, and SOL—not AVAX unless it is SOL—pays later Solana fees.
ETH is the native gas asset for Base. WETH is contract-tracked and can require an allowance before transfer. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger.
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 source token on Base. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Route-specific mistakes include sending on a network other than Base; 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. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. 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. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.
WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Base. The recorded Base representation uses 18 decimal places. 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.
Avalanche is classified as a native asset for this route. AVAX uses a network-specific contract asset on Solana. The recorded Solana representation uses 8 decimal places. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.
Base 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 Base to AVAX 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.
No. The destination must be a Solana-compatible address. Base58-encoded Solana account address
An SPL-token receipt uses the relevant mint and token account; the wallet or route may create an associated token account when needed. SOL is used for later Solana activity.
WETH is a contract representation on Base with 18 decimals at 0x4200000000000000000000000000000000000006. ETH, not WETH, pays gas unless both symbols are the same. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. 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.
AVAX is a contract representation on Solana with 8 decimals at KgV1GvrHQmRBY8sHQQeUKwTm2r2h8t4C8qt12Cw1HVE. SOL, not AVAX, 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. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.
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. On receipt, Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.
WETH is the deposited token input; AVAX is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
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 Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.
Requirements are checked for the live WETH Base to AVAX 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.
