gambid Provably fair
100% onchain

Don’t trust.
Verify.

Every bet on gambid is provably fair and settled 100% onchain. The outcome is locked in before you play, and you can recompute it yourself, right here. No secrets, just code.

How it works

1

Server seed

We generate a secret server seed and show you its SHA-256 hash before you bet, so we can’t change it later.

2

Client seed

You set your own client seed. Your randomness feeds every result, so we can’t predict outcomes.

3

Nonce

A counter that ticks up with each bet, making every outcome unique and provably ordered.

4

Verify

After the round we reveal the server seed. Recompute the hash and confirm the result was fair.
