How this service works
Validate a Solana address: base58, 32 bytes, and whether it is on the ed25519 curve (wallet) or off it (program-derived).
Output
Returns a JSON object with a verdict (valid/invalid), whether the address is on the ed25519 curve (wallet) or off it (PDA), the byte count, hex encoding, input echo, a human-readable summary, an array of validation reasons, any known account name, a degraded flag, and a disclaimer. Failures or invalid addresses include an array of reasons explaining what check failed.
Example use cases
Pre-send address sanity check
“Before I send 5 SOL to DYw8jCTfwHNRJhhmFcbXvVDTqWMEVFBX6ZKUmkL5V4h, can you verify that address is a valid Solana wallet and not a program-derived address?”
Classifying an unknown Solana key
“I found this Solana public key in some contract logs: 11111111111111111111111111111111 — can you tell me if it's a real wallet, a PDA, or if it's even a valid address at all?”
Validating user-submitted deposit address
“A user submitted TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA as their Solana deposit address — can you validate it and let me know whether it's on the ed25519 curve?”
Technical details
Endpoint
GEThttps://web3-tools.x402tookit.com/solana-address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify a Solana public key before using it in a transaction, smart contract call, or user-facing display. It is specifically tuned for Solana (base58, 32-byte, ed25519) and distinguishes wallet addresses from program-derived addresses — something generic address validators or EVM-focused tools do not do.
Side effects
- Address parameter missing — returns error or 400
- Address contains invalid base58 characters — verdict invalid with reasons
- Address decodes to wrong byte length (not 32) — verdict invalid
- Network or service unavailable — degraded flag may be set
- Payment not made — 402 response before result is returned
