The Slab Showdown lobby is an experimental on-chain peer-to-peer mechanic. These terms are the short-form version of every assumption we are asking you to accept when you deposit. The general PowerGacha terms still apply; see /terms.
Slab Showdown lobby entries are not securities, not investment contracts, and not financial instruments. Depositing a card is participating in a peer-to-peer game of chance. No profit expectation from operator effort is being conveyed, and no equity or revenue right in PowerGacha or any related entity is granted.
PowerGacha is not licensed as a lottery, sweepstakes, or gambling operator in any jurisdiction. The Slab Showdown mechanic is provided as an experimental on-chain game between consenting wallet holders, using cards already owned by participants. We make no representation that participation is legal in your jurisdiction. You are solely responsible for determining whether you may participate.
You must not use Slab Showdown if you are located in, or are a resident or citizen of, a jurisdiction that prohibits or restricts games of chance, lottery-style mechanics, or peer-to-peer NFT exchanges. This includes, but is not limited to, jurisdictions with outright gambling bans. You must be at least 18 years old (or the local age of majority, whichever is higher).
When you deposit a card into a lobby, your NFT is transferred to a custodial Slab Showdown wallet operated by PowerGacha until the lobby resolves. During that window we hold the card on your behalf; we do not sell, lend, rehypothecate, or otherwise touch the asset. On resolution the winning wallet receives every non-rake card from the pot in a single on-chain payout. If the lobby fails to resolve due to operator error or chain liveness, we will refund or re-run at our discretion, but we cannot promise an exact timing.
The Slab Showdown rake targets five percent of the pot, taken as the card(s) whose combined USD value most closely matches 5%. Those cards are liquidated and the proceeds buy $GACHA on the open market, which is then burned on chain, removing that supply permanently. The operator keeps no cash rake on the Slab Showdown flow.
A lobby arms once the pot reaches $50 in deposited card value from at least two distinct depositors. A five-minute countdown then runs; qualifying deposits extend the remaining time rather than restarting it, and every round has a hard time cap. When the countdown hits zero the winner is drawn, weighted by each depositor’s USD share of the pot. These parameters are operational settings and may be retuned; the live values are always shown in the lobby UI.
Every Slab Showdown lobby derives its winner from an on-chain ECVRF proof (RFC 9381, Collector Crypt VRF) bound to a future Solana slot blockhash. The binding is fixed to a slot the operator cannot predict, the operator's frozen key produces the proof, and the winner is read from the proof output. No party can steer the result. Older lobbies used a commit-reveal seed scheme; the verifier auto-detects and checks either. The /slab-showdown/fairness/<id> page provides an in-browser verifier so any participant can confirm the roll independently.
Slab Showdown is provided as-is. We make no warranty of merchantability, fitness for purpose, uninterrupted service, or accuracy of any value displayed in the lobby UI. Once a card is deposited and accepted by a lobby it is final: it is either paid to the lobby winner, taken into the rake pipeline, or returned by an explicit refund decision after a lobby failure. There is no chargeback and no support desk.
