EOSIO区块链基础架构提供方EOS Costa Rica和超级节点EOS Argentina今天宣布，它们合作推出Evodex。这是建立在EOS上的去中心化交易所（DEX），其用户投票决定池流动性费用，且无需支付gas费用。团队已经开始封测，并将于9月18日星期五启动。Evodex背后的团队打算利用这个开源的基础架构支持DeFi应用的开发，促进EOSIO上的去中心化金融发展。
“去中心化的p2p交易媒介是一个关键的DeFi工具。” EOS Costa Rica的联合创始人Edgar Fernandez说，“交易促成借贷，这样就会有更多的p2p代币化生息工具，所以Evodex才让人兴奋；这是走向DeFi应用共生生态的一大步。”
Evodex背后的团队灵感来自Bancor和Uniswap简单的界面风格，同时，Evodex考虑着终端用户。前端和网页界面是由EOS Costa Rica构建的。着是通往Evolution Dex 协议的桥梁，而智能合约是EOS Argentina设计的，该智能合约用来和去中心化交易所平台的流量池交互。
除了交易所必须的一些能力—让每个人都能创建和启动交易对、交换EOSIO兼容的代币—以外，其设计发展和优点还包括：
- 可以交换如pBTC之类的跨链包装代币
- 流动性提供方投票决定它们收集到的池费用
- 连接到该协议的所有交易所能共享流动性
- 快速免费的套利交易
- 创造交易对
- 开源的智能合约和使用者界面
“我们搭建的这个开源项目是为了让社区成员能够进行有意义的交易。” EOS Argentina的联合创始人Jesús Chitty说，“这是我们给EOS家族和更广阔的区块链社区发放的邀请函，这样我们才能合约构建更加去中心化的未来。”

EOS Costa Rica, a blockchain infrastructure provider on EOSIO, and block producer EOS Argentina announced today that they have partnered to launch Evodex, a decentralized exchange (DEX) built on EOS where users vote on the pool liquidity fees and pay zero gas. The team has already started its private beta and will be launching on Friday, September 18th. With this open-source infrastructure contribution, the teams behind Evodex plan to support the development of DeFi applications and foster the growth of decentralized finance on EOSIO.
“A decentralized peer-to-peer medium of exchange is the linchpin DeFi tool,” said Edgar Fernandez, co-founder of EOS Costa Rica. “Trading leads into lending, which leads to a wider range of P2P tokenized interest-bearing instruments, and this is what makes building Evodex so exciting; it’s the first major step to a symbiotic ecosystem of DeFi applications.”
The team behind Evodex was inspired by the Bancor and Uniswap simple-interface style, and built it with the end-user in mind. The front-end and web interface was built by EOS Costa Rica. It acts as a bridge to access the Evolution Dex Protocol, while the smart contract was created by EOS Argentina to interact with liquidity pools on the decentralized exchange platform.
In addition to the exchange’s essential capabilities – allowing anyone to create and launch trading pairs, and swap among EOSIO compatible tokens – design improvements and benefits include:
- Swap between cross-chain wrapped tokens like pBTC
- Liquidity providers vote and decide on the pool’s fees they collect
- Shared liquidity among all the exchanges that connect to the protocol
- Fast and fee-less arbitrage trading
- Trading pair creation
- Open-Source Smart Contracts and UI
“We are building an open-source project for meaningful transactions to take place between community members,” said Jesús Chitty, co-founder of EOS Argentina. ”This is an invitation we deliver to the EOS family and the broader blockchain community so that we can collaborate in building a more decentralized future.”
