QuipuSwap stable swap DEX

About

Stable DEX, as a part of the growing QuipuSwap ecosystem, provides a platform for price-efficient and low-risk stablecoin or equal-price token trading. We intend to create a solution for the Tezos ecosystem akin to that Curve and Ellipsis have created for Ethereum and BSC, respectively.

Code of contracts

Contracts overview

Standalone

🏠Standalone DEX

Is the all-in-one contract with a contract admin that allowed to add new DEX pools.

🟠Add new dex

Each pool stored in storage by poolId is an exchange between 2-4 tokens and has a corresponding LP token of FA2 standard with token ID = poold. Main DEX methods of each pool shown at

🔵DEX methods

Also, the standalone includes Developer module inside it (Admin =/= Developer).

Factory

🏭Factory

Allows use DaaS way to deploy new DEX pools for QUIPU fee and use own Stable Exchange with own params. For security reasons, each DEX pool is deployed as a separate contract.

🟠Initialize new DEX flow

These deployed pools almost have the same logic as the standalone variant with a little difference - only one pool per contract. Each contract knows about factory, where located Developer module.

Developer, formally is the administrator of Factory. This address performs the initial setup of lambda methods

🟡Initial setup

and some additional setters

🟢Factory params

The main difference in implementations

In short, the difference is that

Standalone pool	Factory pool
each pool has own poolId, as known as token ID of pool's corresponding FA2 typed LP token	each pool LP token is an FA2 typed with token Id 0 and an unique address
only administrator allowed to add new pools	everyone could start a new pool when paid gas fees and some deploy fee in QUIPU tokens.
contract owns developer params	pool calls factory views for developer params

Developer key values stay in the developer's hands.

Developer represents person or group that create and improve code of Standalone or Factory contract. This address allows to claim fee rewards and manage some values. More info about main developer setter/storage module is shown here
