🔐 cypher •

Introducing Cypher, an on-chain security system to help prevent hacks. Integrate with all of your other preferred protocols and monitoring services.

Website

Deploy your contracts through our frontend with your custom parameters, extend our EscrowContract, and add these lines to your withdraw function:

import { CypherProtocol } from "../../src/CypherProtocol.sol";

contract MockProtocol is CypherProtocol {
  constructor(address deployer, address registry)
    CypherProtocol("MockProtocol", deployer, registry)
  {}
}

ICypherEscrow escrow = ICypherEscrow(getEscrow());
escrow.escrowETH{ value: ethBalances[msg.sender] }(msg.sender, msg.sender, 1);

Features

Deploying contracts for tests

fill out your own .env with these vars:

# RPC URL sourced by scripts
RPC_URL=[enter_here]

# The deployment private key sourced by scripts
DEPLOYER_KEY=[enter_here]

# Etherscan key for contract verification
ETHERSCAN_KEY=[enter_here]

Enter this command to trigger Foundry's shell scripts: bash utils/run_script.sh
Then, when it asks you for the command, enter one of these depending on what you want to test: Deploy DeployProd Mint
Check the chain!

Deployment & Verification

Inside the utils/ directory are a few preconfigured scripts that can be used to deploy and verify contracts.

Scripts take inputs from the cli, using silent mode to hide any sensitive information.

NOTE: These scripts are required to be _executable meaning they must be made executable by running chmod +x ./utils/*._

NOTE: these scripts will prompt you for the contract name and deployed addresses (when verifying). Also, they use the -i flag on forge to ask for your private key for deployment. This uses silent mode which keeps your private key from being printed to the console (and visible in logs).

First time with Forge/Foundry?

See the official Foundry installation instructions.

Then, install the foundry toolchain installer (foundryup) with:

curl -L https://foundry.paradigm.xyz | bash

Now that you've installed the foundryup binary, anytime you need to get the latest forge or cast binaries, you can run foundryup.

So, simply execute:

foundryup

🎉 Foundry is installed! 🎉

Writing Tests with Foundry

With Foundry, all tests are written in Solidity! 🥳

Create a test file for your contract in the test/ directory.

For example, src/Greeter.sol has its test file defined in ./test/Greeter.t.sol.

To learn more about writing tests in Solidity for Foundry, reference Rari Capital's solmate repository created by @transmissions11.

Configure Foundry

Using foundry.toml, Foundry is easily configurable.

For a full list of configuration options, see the Foundry configuration documentation.
