Note to the reader: The target audience for this blog post are mainly developers familiar with Blockchain and Smart Contracts. We have abstracted away business terms in order to focus on the technical process. Not all developers have strong backgrounds in business, economics and finance. Therefore, we recommend reading our blog post on these aspects. The open-sourced code that we share is intended to be inspirational and we do not hold ourselves responsible for any undesired or unexpected behaviour resulted from its usage.

TRON Developer Guide—DECENTRALIZED EXCHANGES—Getting Started

Found: 7/2/2019
Finder: Blockchaindex robot
The TRON network natively supports decentralized exchanges. A decentralized exchange consists of multiple trading pairs. A trading pair (Exchange) is an Exchange Market between token and token, or between token and TRX. Any account can create a trading pair between any tokens, even if the same pair already exists in the TRON network. Trading and price fluctuations of the trading pairs follow the Bancor Protocol. The TRON network stipulates the weights of the two tokens in all trading pairs are equal, so the ratio of their balance is the price between them. For example, let’s say a trading pair contains two tokens, ABC and DEF. ABC has a balance of 10 million and DEF has a balance of 1 million. Since their weights are equal, 10 ABC = 1 DEF?—?that is, the price of ABC to DEF is 10ABC/DEF.

The development of Ethereum Smart Contracts has increased exponentially in 2018 and it seems that 2019 will follow the trend. There are some frameworks, like Truffle, that help us in the process of building and maintaining our Smart Contract but if you like to get your hands dirty, I will explain how to compile your Smart Contract and deploy it to an Ethereum network (Rinkeby, Ropsten or Mainnet) with your own scripts.
