Phylax Standard Library

Phylax Standard Library is a collection of helpful contracts and libraries for use with Phylax. It provides a set of interfaces and contracts to interact with Phylax and Foundry.

Install

Foundry

forge install phylax-systems/phylax-std

Yarn

yarn add @phylax-systems/phylax-std

and add the following remappings to your project by creating the remappings.txt.

forge-std/=node_modules/forge-std/src/
ds-test/=node_modules/ds-test/src/

Forking

Forking uses Foundry in the background, so you can follow the same best practices:

• Set the RPC url inside the contract
• Set the RPC url in an env variable and then use the relevant Foundry cheatcodes to get it
• Set the RPC url inside foundry.toml and use an alias in the contracts

Contracts

Phylax

This is the main interface for interacting with Phylax. It enables the Phylax-only Foundry cheatcodes, such as ph.export(string,string).

Action

This is the base contract for all Phylax alert contracts. It provides a constant reference to Phylax and RE-IMPORTS forge-std/Script.sol.

Action Interface

Read the docs at https://phylax-std.phylax.watch

Action Usage

import { Action } from "phylax-std/Action.sol";

contract PauseProtocol is Action {
    function run() public {
        // pause protocol
        uint256 collateral_left = protocol.collateral_left();
        ph.export("collateral_left", collateral_left);
    }
}

Alert

This is the base contract for all Phylax alert contracts. It provides a constant reference to Phylax and RE-IMPORTS forge-std/Test.sol.

Alert Interface

Read the docs at https://phylax-std.phylax.watch

Alert Usage

import { Alert } from "phylax-std/Alert.sol";

contract CollateralAlert is Alert {

    uint256 polygon;
    uint256 ethereum;

    uint256 BASELINE_BLOCK = 5000;

    function setUp() public {
        polygon = enableChain(<RPC_URL>);
        ethereum = enableChain(<RPC_URL>, BASELINE_BLOCK);
    }

    function testCollateralPolygon() chain(polygon) public {
        // ...
    }

    function testCollateralPolygonBaseline() chain(ethereum) public {
        // ...
    }
}
