Fairness

Limbo

Fairness Checker is a tool that allows players to verify that every bet result was fair and free from manipulation.
OPDuel uses a Provably Fair system that combines a server seed, client seed, and a cryptographic nonce to generate random results that can be independently verified.

To verify a bet, you need three key values:

• Server Seed – A random value generated by OPDuel before the bet is placed.
• Client Seed – A value generated by your browser, ensuring OPDuel cannot control the final outcome.
• Nonce – A unique counter that increases with every bet, preventing results from being predicted or repeated.

Verify Game Fairness– Enter these values into the Fairness Checker to confirm that the random number generated for your bet matches the actual game outcome.

OPDuel cannot manipulate game results: the client seed is set by the player, and all values are hashed and publicly verifiable, guaranteeing full transparency.
