This skill provides Claude with the specialized knowledge required to handle ERC-20 token decimals accurately across diverse EVM-compatible blockchains. It addresses common pitfalls like precision drift in bridged tokens and hardcoded decimal assumptions that lead to massive calculation errors in DeFi applications. By enforcing best practices for runtime decimals() querying, chain-specific caching, and robust math using BigInt or Decimal types, it ensures that balances, USD valuations, and on-chain transactions remain precise and reliable for bots, dashboards, and financial tools.
