COSTA RICA – Sept. 17, 2020 – 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 their private beta and has opened enrollment for early testers. 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.”

Evodex follows the Bancor and Uniswap simple-interface style, built with the end-user in mind. The front-end and web interface was built by EOS Costa Rica 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.”
