# DEX Aggregators

### Overview

Bolt is an on-demand liquidity protocol that delivers **deterministic, zero-slippage execution** using oracle-anchored pricing and inventory-based fulfillment. Bolt does not rely on curve-based liquidity and should be evaluated differently than traditional AMMs.

Bolt is well suited for aggregators looking to:

* Improve execution quality for medium-to-large trades
* Avoid curve-based price impact
* Integrate a deterministic, inventory-backed execution venue

### How Bolt Fits Into Aggregator Routing

Bolt functions closer to an **RFQ / prop-AMM model** than a curve-based AMM.

* Pricing is deterministic and anchored to an oracle
* Execution quality is independent of pool depth
* Trades are constrained only by available inventory
* No curve-based slippage as trade size increases

As a result, Bolt behaves as a **price-stable route** within an aggregator’s routing system rather than a depth-sensitive pool.

### Evaluation Criteria for Aggregators

Traditional metrics such as TVL are not representative of Bolt’s execution quality. Aggregators should instead evaluate Bolt using the following criteria:

* Executable size at zero slippage
* Price quality relative to oracle
* Execution reliability and fill consistency
* Available inventory at execution
* Inventory replenishment and hedging mechanics
* Quote determinism and latency

### Off-chain Quoting & Simulation

Bolt supports off-chain quote simulation, enabling aggregators to efficiently evaluate multiple routes and trade splits without repeated on-chain calls.

Aggregators may:

1. Index or query the current pool state
2. Replicate the contract math off-chain
3. Simulate `amountIn → amountOut` deterministically

This approach supports low-latency quoting at scale.

> Please reach out to the Bolt team to obtain the latest contract math, examples, and reference test vectors. Off-chain simulations should always match the current on-chain implementation.

### Integration Path

Bolt is available today via **TypeScript SDK** integration. Rust support is coming soon.

Typical integration steps:

1. Integrate the Bolt SDK
2. Add Bolt as a routing source
3. Enable off-chain quote simulation (recommended)
4. Validate execution in a test environment
5. Go live and monitor fills

### Summary

For DEX aggregators, Bolt should be evaluated as a **deterministic execution venue**, not a depth-driven AMM. Execution quality is determined by oracle pricing, inventory availability, and replenishment mechanics — not TVL.
