# adex-protocol-eth
The Ethereum implementation of the [AdEx Protocol](https://github.com/AdExNetwork/adex-protocol).
This replaces [adex-core](https://github.com/AdExNetwork/adex-core).
This repository implements [OUTPACE](https://github.com/AdExNetwork/adex-protocol/blob/master/OUTPACE.md) (off-chain unidirectional trustless payment channel) and a gas abstraction layer called [AdEx Identity](https://github.com/AdExNetwork/adex-protocol/issues/10).
### Please note
* Every channel will eventually expire (after `validUntil`), allowing the non-withdrawn portion of the initial deposit to be received back by whoever opened the channel.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](https://github.com/AdExNetwork/adex-protocol) and [OUTPACE](https://github.com/AdExNetwork/adex-protocol/blob/master/OUTPACE.md).## Testing
First, run `ganache-cli` in a separate terminal
```
truffle build # This is important cause js/IdentityProxyDeploy uses artifacts from there
npm test
```## Deployment

### Deployment
```
truffle migrate --network mainnet
truffle migrate --network polygon
truffle migrate --network bsc
```### Verifying on etherscan
```
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
* No use of inheritance for core contracts; inheritance is permitted for deployless contracts
* No reentrancy guards allowed, instead we use the Checks-Effects-Interactions pattern
* All `require`s should have an error message
* No `delegatecall` upgradability; upgradability is achieved via off-chain social consensus
* No emergency stops or pausability: it dilutes the value of smart contracts## Audits

### EIP 1271 `isValidSignature` doesn't work until deployed
Since `isValidSignature` relies on calling the Identity contract through `eth_call`, we need that said Identity contract (proxy) is deployed. With the relayer, this is not true until the first transaction, due to the counterfactual deployment.
dApps can actually work around this by asking the user to deploy the proxy first.
