Decentralized exchangeon Ergo and Cardano

A non-custodial, decentralised exchange that allows a quick, effortless and secure transfer of liquidity between the Ergo and Cardano networks.

Cross-chain exchange

eUTXO model gives unique possibility to have shared liquidity among different types of exchanges on top of Ergo and Cardano ecosystems.

AMM and Orderbook

Classic AMM on the Ergo ecosystem have already been developed and tested. Decentralized Orderbook coming soon.

Transparent tokenomics

In ErgoDEX each actor is incentivized to fulfill his role as best as possible. Users benefit from DEX services, Liquidity providers from protocol fees and the DEX benefits from transaction fixed fees.

In traditional, centralized finance, the act of exchange is facilitated by a trusted third-party, such as a market maker, bookie, or other intermediary. This was accomplished using order-books, where buy and sell orders were matched. These paper order-books eventually turned into centralized exchanges (CEXes), like those used in stock markets.

The act of exchange without trusted parties is one of the most basic features necessary for decentralized finance (DeFi) on top of blockchains. Instead of trusted intermediaries, a decentralized exchange (DEX) works using trusted smart contracts. Many features of centralized, order-book exchanges - such as partial filling of orders, buyback guarantees and so on - have been successfully implemented within smart contracts. In smart contracts, these features are usually composable. Composable elements in smart contracts are good for traders for a number of reasons, such as they make them easier to understand and use.

In DeFi, there are two types of decentralized exchanges (DEXes): order-book, similar to traditional, financial exchanges and Automated Market Maker (AMM). Swap order contracts allows for order-book based DEXes, and these follow traditional financial models. They are well established, and they work best in markets with high liquidity. AMM DEXes are also becoming possible on blockchains with advanced smart contracts. AMM uses mathematical models to set the price and match buyers and sellers rather than merely matching buy and sell orders, as in traditional order-books. AMM is best in markets with low liquidity. One of the features of AMM is that liquidity providers add assets to the exchange for a fee, and the market benefits from an increase in liquidity, smaller latency, limited price slippage, and less market volatility when using this additional liquidity.

Interestingly, one of the unique features of Ergo and Cardano is that, thanks to the eUTXO ledger model they use, liquidity pool contracts for AMM DEXes can be combined with the order contracts used in order-book DEXes. This capability enables shared liquidity among different types of exchanges on the Ergo and Cardano blockchains, which was not possible to do before.

In its early stages, A4 is a decentralized cryptocurrency wallet that, as it evolves,

becomes a full-fledged ecosystem with its own blockchain and utilitarian functions of

the main currency and tokens on its network.

You can see the starting list of tasks in the roadmap. All other updates and features will

be introduced only after a decision by the community.

Having been in the crypto market since 2013 and having participated in dozens of

projects, we have come to the conclusion that the most important thing is to gather

around us a community of like-minded people who truly appreciate the values of the

project.

True enthusiasts who believe in the development of P2E and NFT segments will take on

the emission within about 3 years. This will be a great reward, especially due to the fact

that further projects will be based only on the A4 token. In other words, in order to

build a new metastore in your personal meta city, you will need to buy building materials for A4.

With the VR glasses, you will be able to trade NFTs in the virtual gallery, transfer coins

from one game to another, create tokens for your apps, and pay bills, since A4 credit

will be tied to the Visa\MasterCard.

The A4 architecture was developed after analyzing existing projects based on comments and discussions in chats and forums, rather than team reports as is usually the case.
