Fees
The production fee schedule is not finalized. This page documents the intended structure for pre-launch diligence.
Pre-launch
Fees, rebates, and buyback percentages are subject to governance, legal review, and mainnet launch readiness.
Fee structure
| Fee area | Planned model |
|---|---|
| Trading fees | Maker/taker fee schedule by product and volume tier |
| Vault fees | Deposit and withdrawal flows should remain transparent and minimal |
| Market-maker incentives | Programmatic rebates or emissions for qualifying liquidity |
| Insurance allocation | Portion of protocol revenue reserved for risk events |
Token value accrual
The proposed Tokenomics v2 model frames SPT as a cashflow-linked asset with a buyback-and-burn mechanism.
| Phase | Buyback share of fees |
|---|---|
| Bootstrap | 20% |
| Growth | 30% |
| Maturity | 40% |
Bought SPT is burned on-chain rather than held in treasury, providing deflationary pressure proportional to protocol activity. Final percentages and phase definitions remain subject to governance launch, legal review, and mainnet readiness.
See Tokenomics for allocation, vesting, and fee buyback details.
User-facing requirements
The web application and SDK should expose:
- estimated fee before order submission,
- executed fee on fills,
- maker/taker classification,
- any fee discount or rebate source,
- clear distinction between trading fees and gas costs.
