How SolKeys works
Procedural key generation
SolKeys does not store a database of private keys — that would require impossible disk space. Instead, keys are computed on the fly when you open a page. The page number deterministically defines which 128 seeds appear. Visit the same page twice and you will always see the same keys.
Ed25519 keyspace
Solana uses Ed25519 elliptic curve cryptography. Each valid 32-byte seed maps to a unique keypair and Base58 address. The theoretical keyspace is approximately 2256 — about 1.16 × 1077 keys. At one billion checks per second, scanning the entire space would take longer than the age of the universe multiplied by itself many times over.
Balance checking
When you open a page, your browser queries the Solana mainnet RPC to check each address. Green means the wallet holds SOL. Yellow means the account exists but is empty (it was used before). Red means no account has ever been created at that address.
Security disclaimer
This is an educational demonstration of cryptographic keyspace size. Do not use keys displayed here for real funds. Any key visible on a public website can be seen by others. For real wallets, generate keys offline with audited wallet software or a hardware wallet.
