Provable draws

Every pull is VRF-provable.
Nobody deals from the bottom.

Your authority

Your wallet owns the pool.
We never hold your keys.

Fees, direct

75% of every fee,
paid by the chain itself.

[ The deal ]

Keep 75% of every fee.

About 0.2 SOL and one transaction to launch, nothing to operate. NFW runs the randomness, the cranks, and the backend. You hold the pool and its keys.
