Proof-of-Grind

The rarest Solana addresses ground on three.ws — each one provably-fair and independently verified. Rarity is honest math from the real grind difficulty: longer patterns, real words, palindromes and repeats. Appraise any address, or publish your own ground wallet. Want a hard one ground for you?

Suffix chars

Estimates the rarity tier and the expected grind cost of the chosen prefix/suffix using the same honest model the grinder advertises. Leave the splits on auto to detect a leading word, repeat, or a sensible default. Computed live in your browser — nothing is sent or stored.

Your signed receipt

Display label (optional, public)

Opt-in and secret-free. Publishing adds only your public address and its rarity metadata to the gallery — never a key, seed, or sealed envelope. We re-verify your receipt against the live three.ws service key first, so only provably-fair grinds appear here. Don't have a receipt? Grind a provably-fair wallet →
