AdEx protocol on Ethereum
npm install adex-protocol-ethThe Ethereum implementation of the AdEx Protocol.
This replaces adex-core.
This repository implements OUTPACE (off-chain unidirectional trustless payment channel) and a gas abstraction layer called AdEx Identity.
* Every channel will eventually expire (after validUntil), allowing the non-withdrawn portion of the initial deposit to be received back by whoever opened the channel.
* Channels can be created with any ERC20 token; if the underlying token of a channel is insecure or malicious, that also compromises the channel as well; this is out of scope of this contract, since this is a fundamental issue with any system that uses ERC20s; needless to say, the user needs to be aware of what token they're using/earning
* For more details on how OUTPACE channels work, please read the specs: AdEx Protocol and OUTPACE.
First, run ganache-cli in a separate terminal
``
truffle build # This is important cause js/IdentityProxyDeploy uses artifacts from there
npm test

The full deploy processis as follows
* Deploy AdExCore
* Deploy an IdentityFactory
* Deploy a single Identity, with no owners and no registry
* Deploy a Staking
`
truffle compile
cat build/contracts/AdExCore.json | jq '.bytecode' # this is the bytecode you have to deploy
./scripts/bundle.sh contracts/AdExCore.sol # this will output a bundled .sol code

* Minimalistic use of smart contracts in general
* Avoid putting logic in SCs if it's outcome is controlled by a single entity anyway
* Do not add complexity and centralization to address various "what ifs" that should be addressed off-chain, e.g. "what if users send tokens to this contract by accident"
* Detailed tests for every contract
* No Solidity warnings allowed
* No modifiers allowed
* Limited use of inheritance
* No reentrancy guards allowed, instead we use the Checks-Effects-Interactions pattern
* All requires should have an error messagedelegatecall
* No upgradability; upgradability is achieved via off-chain social consensus
* No emergency stops or pausability: it dilutes the value of smart contracts
* G0 Group: all issues discovered were of Low severity, and all were resolved
* Sigma Prime: 4 issues discovered with "Informational" severity, all resolved
* G0 Group, Staking contract: all issues discovered were resolved
* Forkway, ADXToken: all issues discovered were informational and resolved
