Solana Pay, built on the Solana blockchain, serves as a universal language facilitating streamlined transactions through URLs. This system, which allows for immediate transactions at minimal fees, enhances user experience by providing a smoother payment process. Imagine these URLs as unique web addresses that can be converted into QR codes or NFC tags, or shared among individuals and applications for payment or transaction initiation. Such a setup renders transactions via Solana not only more seamless but also more secure.

Solana Pay provides an open protocol for developers, offering standardized payment specifications that can be built upon and personalized. This flexibility allows merchants to establish direct connections or utilize software developed by e-commerce providers, point-of-sale software creators, or payments companies.

Notably, Solana Pay isn’t designed to mirror credit card payments. Instead, it aims to serve as a digital counterpart to cash transactions. This feature appeals to merchants as it allows them to sidestep expenses associated with intermediary services like Visa or Mastercard, as well as costs arising from chargebacks.

Solana Pay Methodology

Solana Pay introduces an alternative method for users to engage with smart contracts and transfer tokens, allowing users to view and sign transactions via a link instead of connecting a wallet. This approach eliminates the necessity of wallet connection for interaction, streamlining the process for both straightforward payments and app interactions. It effectively accommodates transaction and transfer requests alike.

A standout feature of Solana Pay is its Transfer Request, a non-interactive solicitation for transferring SOL or SPL Tokens. Although it’s crucial to acknowledge that not all Solana wallets support this format, the majority of well-known wallets, including Phantom, Solflare, and Glow, do. Below is an example of what a Solana Pay transfer request URL appears like:

Solana Pay Parameters

Solana Pay encompasses detailed data specifications not accessible during standard token transmission on the network. It incorporates standardized elements like destination, currency, amount, transaction identifiers, and descriptive text fields, all of which aid merchants in verifying transaction completion. Importantly, specific transaction details — including payer identity and purchased items — are not publicly disclosed on the chain.

Below, each parameter is dissected for clearer understanding:

• Recipient: This parameter refers to the public key of the SOL recipient. For transferring SPL Tokens, the token type should be delineated in the ‘spl-token’ field. The wallet utilizes this data to determine the exact account designated for the transfer.
• Amount: Specifies the quantity of SOL or tokens being sent. For amounts under 1, prefix the value with a zero before the decimal point. In the absence of an amount, the wallet prompts you for entry. When transferring SOL, this amount pertains to the SOL value, not lamports.
• SPL Token (optional): This field indicates the mint address of a specific SPL Token type. Omitting this field defaults the transaction to a standard SOL transfer.
• Reference: This unique identifier, embedded within the transaction, assists in locating and verifying particular transactions.
• Label: This is a brief descriptor identifying the origin of the transfer request, such as a store or an application. This information is displayed to users by the wallets for transaction clarification.
• Message: The parameter contains an encoded URL detailing the reason behind the transfer, possibly including purchase items, order ID, or a simple message. Wallets use this to offer users additional transaction context.
• Memo: This field allows for the inclusion of notes within the payment transaction, void of private or sensitive data, as it will be stored on-chain.

These parameters collectively empower you with full transaction control, simplifying the interaction between your wallet and the recipient. For enhanced security, it is recommended that applications only process transactions post their on-chain confirmation.
