Glossary

Key terms and concepts used throughout the Chisino documentation.

$HOUSE

The governance token of the Chisino protocol. Fixed supply of 10,000,000. Not sold — distributed through gameplay (1 $HOUSE per pUSD played) and liquidity provisioning. Stake $HOUSE to receive sHOUSE and earn protocol fees.

Eligible Supply

The amount of pUSD held in user wallets (not in protocol contracts). Only eligible supply earns fee rewards from the FeeDistributor. Creates a natural tension between playing (which locks pUSD in contracts) and holding (which earns passive fees).

Fee Pool

Accumulates protocol fees (0.05 pUSD per play + 50% of TCV yield). Distributes 70% to pUSD wallet holders via FeeDistributor and 30% to sHOUSE stakers via HouseStakingRewards.

MegaETH

The high-performance EVM blockchain that Chisino is built on, offering low latency and fast transaction throughput.

Prize Pool

Funded by 1.00 pUSD per play plus proportional yield allocation. Holds pUSD for instant reward payouts to players. Cannot distribute more than its current balance.

pUSD

PlayUSD — The protocol's ERC-20 receipt token. Deposit USD stablecoins (USDm or others on MegaETH) and receive pUSD at 1:1. Used for all gameplay. Redeemable anytime for underlying stablecoins. Holding pUSD in your wallet (not in contracts) earns 70% of fee distributions pro-rata.

RPT

Reward-Per-Token — A mechanism for fairly distributing rewards to token holders or stakers proportional to their share over time. Used in both the TCV (for ticket restoration) and HouseStakingRewards.

Session Key

A temporary wallet authorized to participate on your behalf, enabling gasless scratch card reveals without signing each transaction individually. Managed by the GameSessionFactory contract.

sHOUSE

ERC-20 staking receipt received when you stake $HOUSE. Holding sHOUSE earns 30% of Fee Pool distributions pro-rata. Transferable. You must stake $HOUSE to earn fees — holding $HOUSE alone does not.

TCV

Ticket Claim Vault — Holds 1.95 pUSD per play. Deploys capital to yield-generating strategies. 50% of TCV yield goes to ticket restoration (growing each ticket from 1.95 pUSD toward the 3.00 pUSD recovery target). 50% goes to the Fee Pool.

VRF

Verifiable Random Function — Currently using Goldsky for cryptographically secure on-chain randomness. Planned upgrade to MegaETH's native VRF. Ensures all scratch card outcomes are provably fair and cannot be manipulated by participants, operators, or validators.
