Transfer Request (Solana Pay)

The simpler of the two Solana Pay sub-protocols, encoding a static SOL or SPL token payment request as a URI in the format solana:<recipient>?amount=<value>&spl-token=<mint>&label=<label>&memo=<memo>. Transfer Request URIs are fully self-contained and require no server interaction — wallets parse the URI and construct the system program transfer or SPL token transfer instruction locally, making them ideal for fixed-price invoices and tip links.
