All projects on Solana matching “randomness”

Verifiable RNG — cryptographically-random integer(s) signed by the treasury key. Drop-in VRF for game studios. $0.001 USDC.

Use this to check a draw independently: recomputes the SHA-256 of a revealed server_seed against its hash, and the numbers of a swoge-hmac-sha256-v1 draw, or the 52-card shoe of a SWOGE casino hand (scheme swoge-casino-shoe with its nonce). Price: $0.003 in USDC on Base or Solana, or $0.02 in USDG or $SWOGE on Robinhood Chain (tool price + settlement cost, minimum $0.02).
