Solana Pay

Solathon follows the canonical Solana Pay specification for transfer URLs and transaction-request URLs.

The v2 helpers cover:

lossless URL encoding and parsing with Decimal amounts;
native SOL, classic SPL Token, and basic Token-2022 transfer creation and validation;
ordered references and signed memos;
safe HTTPS transaction-request fetching without forwarding RPC credentials;
optional branded QR generation through solathon[qr].

Basic Token-2022 payments are supported. Creation rejects transfer-fee and transfer-hook extensions, UI-transforming interest/scaled-amount mints, non-transferable or paused state, and unknown extensions where their safety cannot be established. These cases require extension-specific handling.

Start with Encode URL, then use Create Transfer or Fetch Transaction for the appropriate Solana Pay request type.
