README.MD is out of date. Contract is not fully works too.

TradingContract

A smart contract with the ability to trade one token against others, eliminating the need for centralized trust.

Deploy

when deploy it need to pass parameters in to constructor

name	type	description
_token1	address	address of first erc20token
_token2	address	address of second erc20token or zero-address (in this case exchange will be erc20token/ETH )
_numerator	uint256	price increment
_denominator	uint256	how much ether to next price
_priceFloor	uint256	price floor
_discount	uint256	99% * 1e6 (used for calculate sellExchangeRate)
_token1Fee	uint256	fee accural for all deposits when some1 withdraw
_token2Fee	uint256	fee accural for all deposits when some1 withdraw

Methods

once installed will be use methods to exchange Note that contract accept tokens, it should be approve before (for contract address)

• function depositToken1(int256 blockCount)
  

if blockCount < 0 tokens will be donated if blockCount = 0 tokens will be exchanged to token2 if blockCount > 0 tokens will be deposited and can be withdraw after blockCount blocks

• function depositToken2(int256 blockCount)
  

if blockCount < 0 tokens will be donated if blockCount = 0 tokens will be exchanged to token1 if blockCount > 0 tokens will be deposited and can be withdraw after blockCount blocks

• function viewDepositsToken1()
  

• function viewDepositsToken2()
  

• function withdrawToken1()
  

• function withdrawToken2()
  

Examples

• how to donate tokens
  • call method approve from erc20 token approve(<address TradingContract>, <amount tokens>)
  • call method depositToken1 from TradingContract depositToken1(-1)
• how to exchange tokens from token1 to token2 immediately
  • call method approve from erc20 token approve(<address TradingContract>, <amount tokens>)
  • call method depositToken1 from TradingContract depositToken1(0)
• how to deposit tokens to TradingContract i.e for 100 blocks and withdraw
  • call method approve from erc20 token approve(<address TradingContract>, <amount tokens>)
  • call method depositToken1 from TradingContract depositToken1(100)
  • call method withdrawToken1 from TradingContract withdrawToken1()

Note

1. blockCount it is duration in blocks NOT BLOCK NUMBER
2. eth deposit will be available if
   1. contract created with token2 = address(0) and
   2. transaction with method depositToken2() are payable
