# let users swap tokens inside my app

> Uniswap supplies the liquidity and routing for in-app swaps, a price oracle like Pyth backs slippage and quote sanity checks, and a low-cost L2 such as Base keeps per-swap gas affordable.

## Recommended stack

- **Uniswap** (supporting_protocol) — readiness 94/100, difficulty medium — AMM with the Universal Router for routing swaps, plus SDKs for quoting and building trades.
- **Pyth Network** (oracle_and_price_data) — readiness 82/100, difficulty medium — Reference prices for slippage limits and showing fair quotes to users.
- **Base** (settlement_or_execution) — readiness 82/100, difficulty low — Low-cost L2 execution so swap gas stays affordable for consumer users.

## Risks

- Always set an explicit minimum-output / slippage bound; unprotected swaps are an MEV target.
- Quote and execution prices can diverge; refresh quotes close to submission.

## Next steps

- Integrate the Uniswap SDK to fetch quotes and build swap calldata.
- Add slippage protection and a reference price check before submitting.
- Test on the chosen L2's testnet, then mainnet with small amounts.
