Solana Address Validation

Check a Solana address: the base58 alphabet and the 32-byte key length. Solana addresses carry no checksum, so this checks the structure only.

Limitations

Format only — no on-chain check, no checksum
Checks only that the base58 input decodes to 32 bytes; Solana addresses have no checksum. Single-character typos can remain structurally valid and are not detected.
What to do instead: For high-stakes flows, verify the address controls funds via an on-chain lookup before sending.
Cannot distinguish wallets, PDAs, and program accounts
All Solana account addresses are 32 bytes regardless of whether they are user wallets, Program-Derived Addresses (PDAs), or program accounts. This validator confirms the shape but does not classify.
