Collect · Rip Room

Ripping a pack sends one requestV2(provider, userRandomNumber, gas). The generator reveals a single 256-bit randomNumber; we expand it into 5 independent pulls with keccak256(randomNumber ‖ slot) — slots 1–3 common-tier, slot 4 uncommon+, slot 5 the guaranteed rare-or-better hit (with epic/legendary + holo upgrade rolls). Because the provider's hash-chain value was committed before your request (SPEC §7.1), neither you nor the provider can steer which cards drop, and anyone can recompute the pull from the on-chain Revealed event + the shown seed.
