With Solana Pay, merchants can accept the USDC stablecoin, Solana's native token SOL, and other Solana-based tokens on the Solana blockchain. Transactions will be instant, said Solana Labs, adding that merchants will receive "real-time" payments.
"If people can seamlessly transact on-chain just like they do with cash, we believe that will spur interest and create new innovations which is why the protocol is designed to allow for developers to build new commerce experiences on top of it."
