Dynamic Fees for DeFi

Fees that respond to volatility, reward loyalty, and defend against MEV. Powered by verified onchain data and zero-knowledge proofs.

From onchain history to verified fee logic

Any smart contract can query historical blockchain data and get a ZK-proven result back onchain. Three steps, zero trust assumptions.

1. Query

Your smart contract sends a SQL query to SXT's QueryRouter. The query runs against indexed blockchain data, trading volumes, LP positions, borrower history, staking duration, or any onchain signal your pricing logic needs.

2. Prove

The SXT network executes the query and generates a Proof of SQL, a ZK proof that the result is mathematically correct and the underlying data hasn't been tampered with. No trust in any single node required.

3. Callback

The verified result is delivered to your contract's callback function. It maps the data to a fee adjustment, a discount tier, a volatility surcharge, a risk premium, a loyalty credit, and applies it directly in your contract's business logic.

Pricing that creates a compounding advantage

Dynamic fees turn protocol pricing from a static parameter into a competitive weapon, across every DeFi vertical.

Better LP Economics

Pools charge more during volatile periods, compensating LPs for impermanent loss risk. In calm markets, lower fees attract volume. LPs earn more on a risk-adjusted basis either way.

MEV Defense

Fees that spike for trades exhibiting sandwich-attack or toxic-flow patterns shift the cost of extraction from liquidity providers to the extractors themselves.

Loyalty & Retention

Volume-based discounts and loyalty tiers reward users who contribute the most to protocol health. Verified onchain history replaces manual allowlists and governance votes.

Smarter Risk Pricing

Lending rates, borrowing costs, and collateral requirements that incorporate real-time utilization, borrower history, and cross-protocol exposure. Accurate pricing for every position.

Dynamic fees across every DeFi vertical

Any smart contract that prices a service can use verified historical data to price it better.

Swap Fee Optimization

Volatility-responsive fees, volume-based discounts, and MEV-aware pricing. Compatible with Uniswap v4 hooks and any AMM with programmable fee logic.

Risk-Adjusted Rates

Borrowing costs that factor in repayment history, collateral quality scores, and real-time utilization. Better rates for proven borrowers, tighter terms for new ones.

Adaptive Funding Rates

Funding rates and trading fees that respond to open interest concentration, trader history, and cross-exchange basis. Tighter spreads for organic flow, wider for toxic.
