Fees & Economics
Understanding how SOLBET works under the hood.
House Edge
Every game has a small mathematical edge that ensures platform sustainability:
| Game | House Edge | Example |
|---|---|---|
| Coin Flip | 2% | Bet 100 → Win 196 (not 200) |
| Dice | 2% | True odds × 0.98 |
| Blackjack | 0.5% | With optimal strategy |
| The Styx | 2% | True odds × 0.98 |
💡 These edges are much lower than traditional casinos (typically 5-15%).

Fees are only taken from house profits, not from winners.
- When you win: You keep your full payout
- When you lose: A portion goes to protocol
Fee Formula
Protocol Fee = House Edge ÷ 2
| Game | House Edge | Protocol Fee | LP Gets |
|---|---|---|---|
| Coin Flip | 2% | 1% | 1% |
| Dice | 2% | 1% | 1% |
| Blackjack | 0.5% | 0.25% | 0.25% |
| The Styx | 2% | 1% | 1% |
Example
Player loses 100 tokens on Coin Flip:
- LP Pool receives: ~1 token
- Protocol Treasury: ~1 token
- Total edge: ~2 tokens
Special Token Types
Different tokens may have different fee structures:
| Token Type | Protocol Fee | Note |
|---|---|---|
| Standard tokens | Normal (edge ÷ 2) | Default behavior |
| GRIM | Burned 🔥 | Deflationary |
| Partner tokens | 0% | 100% to LPs |
Bet Limits
To protect liquidity pools, bets are capped:
- Max Win Cap: Your potential win cannot exceed a % of the pool
- Multiplier Scaling: Higher multipliers = lower max bets
- Dynamic: Limits adjust as pool size changes
This prevents anyone from draining the pool with a single lucky bet.
Other Fees
Liquidity Early Withdrawal
- 1% fee if withdrawn within 1 hour of deposit
- 0% fee after 1 hour
This prevents flash-loan attacks.
