EscrowContract

A smart contract with the ability to exchange one token against others.

Deploy

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

Methods

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

deposit

Params: name | type | description --|--|-- tokens|address| address of token.

unlock

Examples

• 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 swapBackAfterEscrow is true)

Notes:

1. 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
