Credits & Fees
Sigma Engine has two fee models depending on the exchange you trade on.
How It Works
Builder Fee Exchanges (Free to Use)
On these exchanges, there is no platform fee. A small builder fee (0 to 2.5 bps depending on the exchange) is handled by the exchange itself — you pay nothing extra to use Sigma Engine. No credits needed. Some exchanges charge zero builder fees entirely.
Supported: Hyperliquid, HotStuff, Extended, Hibachi, GRVT, Pacifica, Aftermath, DreamCash, TradeXYZ
Credit-Based Exchanges
On these exchanges, a small platform fee is deducted from your prepaid credit balance per trade. Fees are volume-tiered — trade more to unlock lower rates.
Supported: 01 Exchange, Ethereal
Credit Fee Tiers
Fees are based on your rolling 30-day trading volume across all credit-based exchanges.
| Tier | 30-Day Volume | Fee Rate |
|---|---|---|
| Starter | $0 — $250K | 3.0 bps |
| Intermediate | $250K — $1M | 2.5 bps |
| Trader | $1M — $5M | 2.0 bps |
| Advanced | $5M — $15M | 1.5 bps |
| Pro | $15M — $40M | 1.0 bps |
| Elite | $40M+ | 0.5 bps |

- Minimum balance: $20
- Only send USDC or USDT on supported chains
- Do not send unsupported tokens — they cannot be recovered
