Core smart contracts for Dexter v1

Dexter :: Architecture Overview

Dexter is the first DEX which is implemented as a generalized state transition executor where the transition’s math computes are queried from the respective Pool contracts, enabling a decentralized, non-custodial aggregated liquidity and exchange rate discovery among different tokens on Persistence.

Scope

At launch, it will support the Stable Pool type (introduced by curve) and the Weighted pool type (introduced by balancer), each of which designed for the following objectives:

• Stable Pool: Can be leveraged to develop specialized pools for liquid staking assets which can provide best trade execution.
• Weighted Pool: Can be leveraged to develop re-balancing driven pool strategies which can maximize LP returns.

Router can be used to perform trades across different pools in one go, while Multitasking (a modified version of the Anchor staking contract) can be used to incentivize pool’s LP tokens with rewards that is given by any 3rd party.

Development

Dependencies

• Rust v1.44.1+
• wasm32-unknown-unknown target
• Docker

Envrionment Setup

• Install rustup via https://rustup.rs/
• Add wasm32-unknown-unknown target

  rustup default stable
  rustup target add wasm32-unknown-unknown

• Compile contracts, test them and generate wasm builds. Make sure the current working directory is set to the root directory of this repository, then

  cargo build
  cargo test
  docker run --rm -v "$(pwd)":/code \
    --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target \
    --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
    cosmwasm/workspace-optimizer:0.12.12

• Use dexter deploy cli to deploy them on the persistence network.
