What problem does it solve?

Non-standard ERC-20 token integrations pose safety risks in smart contracts, including unexpected behavior from tokens like USDT, USDC, or rebasing assets. This Skill provides patterns to ensure safe interactions and robust handling across deposits, withdrawals, and approvals.

Core Features & Use Cases

  • SafeERC20 usage with forceApprove to mitigate USDT quirks.
  • Decimals awareness for non-18-decimal tokens and blacklists handling.
  • Handling fee-on-transfer, rebasing tokens, and ERC-777 callbacks.
  • Permit2 integration guidance for gasless approvals.
  • Token quirks reference and integration checklist for production safety.
  • Real-world use cases: vaults, adapters, and cross-token finance modules.

Quick Start

Apply safeERC20 patterns to a non-standard token transfer in a vault example.
