# DEX Aggregators
> The highest-earning pool type any DEX aggregator can integrate
For DEX aggregators, C1 Pools are the highest-earning pool type available to integrate, and the only liquidity source that mathematically guarantees better user execution on thin-liquidity tokens.
## Why integrate C1 Pools
The aggregator share of the 1% seller fee is paid on every routed trade. No commercial negotiation, no decay, no incentive expiry.
Zero slippage means the C1 quote always wins the price comparison on supported tokens. Better user execution drives stickier users and higher volume retention.
Buyers receive zero slippage. An additional 0.10-0.20% aggregator margin still delivers better net execution than any AMM. C1 routing creates a revenue-stacking opportunity unique in DeFi.
The C1 Pool registry is permissionless. Routing is decided by the aggregator's own price comparison logic. The relationship is mathematical, not commercial.
## How the economics compare
A typical Uniswap V3 integration earns the aggregator nothing. The 0.30% LP fee goes entirely to liquidity providers. Aggregators earn from spread capture, gas optimisation or front-end fees, not from pool routing itself.
C1 Pool integration earns on both sides of the trade. The protocol pays 0.30% of every routed trade to the aggregator from the seller fee. Because buyers pay zero protocol fee and receive zero slippage, the aggregator can apply an additional 0.10-0.20% buy-side margin and still deliver better net execution than any AMM.
On a \$100K routed trade, that is \$300 from the seller fee share plus \$100-200 from the buy-side margin. Total aggregator revenue of \$400-500 per execution, compounded across the volume an aggregator already routes.
| Pool type | Seller-side fee share | Buy-side margin headroom | Notes |
| ----------- | --------------------- | -------------------------------------- | ---------------------------------------------------------- |
| Uniswap V2 | 0% | Limited by AMM slippage | LP fee captures the entire 0.30% |
| Uniswap V3 | 0% | Limited by AMM slippage | Same model, narrower ranges |
| RFQ / PMM | 0% | None, PMM captures the spread | PMM captures the spread |
| **C1 Pool** | **0.30%** | **0.10-0.20% on top of zero slippage** | **Only pool type that earns the aggregator on both sides** |
## How integration works
C1 Pool contracts register with FlowState's liquidity registry on each supported chain. Aggregators look up pools by token or enumerate all deployed pools on the chain. See [Integration Overview](/integration/integration-overview#liquidity-registry).
C1 Pools are added to the aggregator's routing graph alongside AMMs, RFQ sources and other liquidity venues. The aggregator's existing price comparison logic handles the rest.
When the router selects C1, settlement is atomic in the same transaction. No off-chain coordination, no signed quotes, no settlement risk.
The 0.30% aggregator share is distributed at settlement. No batched claims, no end-of-period reconciliation.
Integration timelines vary based on the aggregator's routing architecture. Live integrations have completed in two to four weeks of engineering time.
## Current integrations
| Aggregator | Status |
| ---------- | -------------- |
| KyberSwap | Live |
| OKX DEX | In integration |
| Odos | In integration |
| 1inch | In pipeline |
## Common questions
C1 Pools include multi-source aggregation, TWAP smoothing, circuit breakers, deposit and withdrawal rate limits and minimum oracle confidence thresholds. See [Audits & Security](/resources/audits-and-security) for the full mitigation set.
Live on Ethereum, Arbitrum, Base and BNB Chain. Additional EVM chains added based on routing demand. Solana support arrives via Oasis (separate brand) on its own roadmap.
Distributed at settlement in the trade's base currency (USDC or ETH). No claim transactions required.
Depth scales with depositor coverage per token. Aggregators that integrate early get pool growth as part of their routing improvement curve.
