A smart contract with the ability to exchange one token against others.
when deploy it is need to pass parameters in to init method that started new escrow mechanism
Params:
| name | type | description |
|---|---|---|
| participants | address[] | addresses list of participants who will exchange own tokens. see Note#1 |
| tokens | address[] | addresses list of tokens. see Note#1 |
| minimums | uint256 | minimum amount list of tokens. see Note#1 |
| duration | uint256 | escrow duration in seconds. started after escrow have been locked up |
| quorumCount | uint256 | how participants need to deposit minimum tokens that escrow will be locked up |
| swapFrom | address[] | addresses list or participants which tokens will be swapped from. see Note#2 |
| swapTo | address[] | addresses list or participants which tokens will be swapped to. see Note#2 |
| swapBackAfterEscrow | bool | if true, participants can withdraw own deposited tokens after escrow expired |
once installed will be use methods to exchange Note that contract accept tokens, it should be approve before

there are no parameters
there are no parameters
- life cycle
- deploy contract
- all participants deposited own tokens until escrow locked up
- escrow started and all participants starting to unlock own deposited tokens in favor to recipients. Now in any time recipients can withdraw tokens
- if duration passed - escrow are expired. Now all participants can withdraw own tokens which are not locked (if param
swapBackAfterEscrowis true)
Notes:
- participants/tokens/minimums are combined and linked arrays with the same length. It is means that if participant#1 have address '0x1111...' and want to trade 100 tokens with address '0x2222...' than
participants=['0x1111...']
tokens=['0x222...']
minimums=[100]
if will be added participant#2 with address '0x3333...' and want to trade 200 tokens with address '0x4444...' than
participants=['0x1111...','0x3333...']
tokens=['0x222...','0x4444...']
minimums=[100,200]
and so on 2. swapFrom/swapTo are combined and linked arrays with the same length too
