DEX Pre-Launch Architectural Changes

It has been 21 months since then initial announcement of the Acuity DEX. While the core concept of the atomic swap has remained the same during that time, the rest of the system has been re-designed many times. This can be see both from the blog posts below and from the GitHub activity.

DEX Development Update

The Acuity DE will be a fully autonomous and decentralized atomic swap cross-chain cryptocurrency exchange. It will support ACU, and both base coins and ERC20 tokens on all EVM compatible chains. It has a number of advantages over other cross-chain exchanges & bridges.

ACU is becoming a DeFi-only coin

As detailed in the earlier blog post below "Acuity Atomic Swap DEX - the future of interchain trading", centralized exchanges are not only a risk to those storing their coins on such exchanges. CEXs are actually a systemic risk to the trading price of coins that are traded on them. It is a security vulnerability for a project to have its coin listed on a centralized exchange.

Acuity DEX Alpha Testing

The Acuity DEX is approaching minimum viable product. To begin with it will have a simple pair ACU / ETH. It will be possible to trade ETH stored in Metamask for ACU stored in the Polkadot browser extension. The Solidity smart contracts and the Substrate pallet are both mature. Development of a Rust-based off-chain worker to index the order book continues. Basic UI is coming together.

ACU / ETH atomic swap exchange under development

I'm currently working on a very simple atomic swap exchange for Acuity. This will be implemented as a Solidity smart contract and deployed on both the Ethereum and Acuity blockchains so ACU can be traded with ETH in a fully decentralized manner and without any counterparty risk.
