Back the house. Earn the edge.
Provide USDC liquidity to the topbit bankroll and take the house side of every bet. You earn a share of the edge when players lose, and you cover the payouts when they win. It is real risk capital, not a yield account.
The other side of the table
Every casino runs on one structural advantage: across enough bets, the house keeps a small, predictable margin. On topbit, players hold their own wallet and can verify every settlement there. The catch has always been that you had to own the casino to be on the winning side of that math.
topbit opens that side up. The bankroll that pays winners and banks losers is on-chain, and anyone can fund it. Provide USDC liquidity and you are the house: you take a share of the edge when the floor is up, and your stake covers the payouts when players run hot.
How it works
Deposit USDC into the vault and receive $TLP, a token that represents your proportional share of the bankroll. The price is plain arithmetic: $TLP equals the vault balance divided by the $TLP supply. No oracle, no dependence on any token price.
When the house is up, the vault grows and each $TLP is worth more. When players win more than they lose, the vault pays them and your share falls with it. You withdraw your share in USDC, subject to a tier cooldown that runs from 3 days for the largest providers to 14 days for the smallest.
What you earn
Your tier sets how much of the house edge you keep versus what flows on to the protocol. Bigger, longer-committed liquidity keeps a larger share. During the first 90 days after launch (the Bootstrap window) every tier earns a flat 75%, regardless of size.
| Tier | Deposit (USDC) | LP share | Cooldown |
|---|---|---|---|
| Elite | < $500 | 65% | 14 days |
| Premier | $500 to $2.5k | 70% | 10 days |
| Executive | $2.5k to $10k | 75% | 7 days |
| Director | $10k to $50k | 80% | 5 days |
| Whale | > $50k | 85% | 3 days |
Returns track real gaming results. A winning week for players is a losing week for the bankroll, and the share above is of the edge, not a fixed or promised rate. See how the house pays you, step by step.
The risk, stated plainly
Being the house means carrying the house's risk. The edge is in your favour over a long run of bets, but variance is real and a bad stretch is paid out of the vault, which means out of your share.
TLP holders bear the full downside of vault losses. There is no minimum guaranteed withdrawal amount. In extreme loss scenarios, vault balances can reach zero. This is risk capital. Only provide what you can afford to lose.
Founding Banker: 21 seats
The first liquidity providers can claim one of 21 Founding Banker seats, a cap written into the bytecode that no admin can raise. A seat takes a single $5,000 USDC deposit and grants the top 85% LP share for your first 90 days, measured from your own seat-claim, plus a permanent on-chain badge that stays with the wallet for good.
Seats are first-come and limited to 21. The 85% rate is the launch perk; after your 90-day window it reverts to your tier rate. The badge is identity, not a promise of return.
Two ways to back the house
There are two distinct ways to stand behind topbit, and a single wallet can do both.
Provide USDC liquidity, hold $TLP, and take a share of the house edge. You carry the bankroll's risk and its upside. This is the LP path.
Hold and stake $TOP to earn a weekly USDC cut of protocol revenue, plus a loyalty multiplier on your own play. This is the token path.
