Solana
Solana is a public blockchain network. The Solana Foundation, the non-profit dedicated to its ecosystem, describes the network as permissionless: anyone can take part in securing it as a validator. It is one of the networks the x402 specification defines a payment scheme for.
The x402 specification carries a document of its own for Solana. It defines the exact scheme there: the paying client brings about an on-chain payment of an exact amount of a named asset to a named recipient. The entry on a scheme says what a scheme is.
The same document separates the payment from the transaction fee. A Solana transaction has a fee payer, and the specification lets that be the merchant or a third-party facilitator, so a buyer holding the payment asset and nothing else can still pay.
A payment challenge names Solana as it names any network, by an identifier in CAIP-2 form. A server can therefore list a Solana option beside an option on another network, such as Base, in one reply.
