A privacy-centric Request-For-Quote DEX on Aleo
Arcane.Finance is a decentralized exchange on Aleo that offers two major benefits:

Constant function Automated Market Makers (AMMs), such as Uniswap or Curve, are perhaps the most integral part of the traditional DeFi ecosystem.
While having many advantages, AMMs on Aleo cannot fully utilize the core privacy-enabling primitives of Aleo: off chain transition functions and encrypted Records. Because an AMM needs to know up-to-date pool reserves, most of its code has to be placed in a finalize function, which is executed on chain and cannot operate on Records. This can fixed by relaxing constraints on price function invariant, but this introduce new challenges e.g. with correct handling of slippage.
For the Aleo ecosystem to grow and be competitive, its decentralized exchanges need to leverage unique privacy-preserving features of Aleo and off-chain computation. This is why we are building a DEX on an entirely different model called "Request-For-Quote" (RFQ).
Request-for-quote (RFQ) is a form of P2P swaps. Our protocol offers users OTC (over-the-counter) desk experience, but automated, private and cryptographically signed.
Here’s traditional how OTC trades work:
Now imagine that you receive cryptographically signed quotes from several sellers, automatically pick the best deal and can execute the trade immediately if you like it. And all this while remaining private. Sounds good? This is exactly how our RFQ DEX works.
In a nutshell, an AMM pricing function x*y=k is now replaced with a cryptographically signed, private quote, which is verified off chain, in a transition. The pricing is done off chain but the trade is executed on chain.
While this project is an early stage Proof-of-Concept, it already shows that Aleo enables building privacy-preserving DeFi protocols that have real competitive advantages over existing solutions.
There are other considerations behind our choice of RFQ model on Aleo:
Institutional Adoption RFQ model is rooted in traditional financial markets. The adoption of RFQ mechanics can attract to Aleo more sophisticated, institutional participants, with deep liquidity and diverse assets.
Expansion to Other Asset Classes RFQ-based execution engines are extremely flexible and can easily be expanded to accommodate derivatives and other financial instruments.
Transformation into Dark Pools Our long term vision includes an extension to RFQ model that would allow for completely trustless, but fully regulated dark pools. This will provide additional liquidity and anonymity for trading large blocks of securities without incurring market impact costs.
