# Kipseli PropAMM

## Docs

- [Get Orderbook](https://docs.kipseli.capital/api-reference/get-price.md): Returns the latest cached on-chain orderbook for all configured token pairs. The cache refreshes on every new block via `eth_subscribe`, so the data always reflects the most recent chain state.
- [Request Swap Verification](https://docs.kipseli.capital/api-reference/sign-quote.md): ABI-encodes `(tokenIn, tokenOut, timestamp, fee, originRate, userAddress)`, Keccak256-hashes the payload, and signs it with secp256k1. The recovery ID is adjusted from `[0,1]` to `[27,28]` per the Ethereum Yellow Paper.
- [Kipseli PropAMM](https://docs.kipseli.capital/index.md): Integrate with Kipseli PropAMM — a professional AMM for token swaps on Base Mainnet
