Components

1. Compile
   • Optimizer to maximize gas cost savings. ref1, ref2, ref3
     • low value: smaller bytecode size and cheaper deployment.
     • high value: larger bytecode size and cheaper execution.

• Directories
  • contracts: smart contracts
  • ignition: deploy smart contract
  • scripts: run
  • test: test smart contract

1. Ignition

• Ignition

  • Problem: getting caught up in the deployment details.
  • Solution: Declarative approach provides Hardhat Ignition with the autonomy to determine the best way to execute your deployment.
  • Pros: It leverages this advantage to execute steps in parallel, manage and recover from errors, resume interrupted or partial deployments, and even adapt to modifications in your modules.

• Reconciliation. 재배포 하기 전, WIPE

  npx hardhat ignition wipe deploymentId futureId (e.g. npx hardhat ignition wipe chain-7331 SBTModule#SBT)

2. Testing

• Fixture

  • Problem: code duplication → make the test suite much slower.
  • Solution: fixtures. a setup function that is run only the first time it's invoked.

• Codes

  3. ERC Standards

3. Audit

• Tools: MythX, Slither, securify2(deprecated)

3-1. Slither

• Installation, Detectors, youtube

• Command

• Errors

  • urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate
  • Slither Tool Error On Contract That Inherit From Openzeppeling

4. Plugins
