## Tycho – the open swap indexer

Indexing, simulating and executing swaps over DEX liquidity is THE barrier to entry for solvers, routers, searchers, market makers integrating DEXs.&#x20;

It took us, and other solvers, years, multiple infrastructure rewrites and millions in developer and infrastructure cost to build.

Tycho removes this barrier to trade on-chain – by making it all open source. Now

* DEXs and solvers collaborate on integrations
* Solvers can focus on generating new value, and
* DEXs get all flow in one integration

## Turbine – the dark solver

Turbine makes the orderbook, solver and the block builder entirely trustless. Verifiably protecting trades from all information leakage.

Turbine also eliminiates latency and priority auctions (and the resulting LVR and MEV).

Turbine Docs (soon).

## PropellerSwap

Turbine is the first direct-to-solver Swap. Swap without delay and without publishing your intent against our Solver – powered by Tycho.

[Swap on PropellerSwap](https://swap.propellerheads.xyz/).

## Open Finance

Open Finance is an initiative to collaborate on standards, open source and monitoring, to build a decentralised and trustless trade supply chain.

Our first meeting happened during Sequencing Week in Chiang Mai.

(more soon).

### ERC-7815

[ERC-7815](https://www.erc7815.org/) is a standardized interface for on-chain swap liquidity. It defines methods to calculate price, swap tokens, retrieve trading limits, and query capabilities of liquidity pools.

Aims to simplify access to defi liquidity sources – to improve composability and make routing (solving), MEV capture (searching), and other defi functions easier.

Developed jointly with Solvers, Solver Auctions, DEXs and Market Makers.
