Does this skill help with database consistency?

Yes, it provides guidance on ACID transactions and defining clear ownership boundaries to ensure that money never 'disappears' or 'appears' during complex multi-step operations.

Why does this skill prohibit using f64 for money?

Floating-point numbers like f64 suffer from binary representation errors that lead to precision loss during calculations. This skill enforces the use of rust_decimal::Decimal for exact base-10 precision required in finance.

What is the benefit of the Currency Newtype pattern?

The Currency Newtype pattern uses Rust's type system to ensure you cannot accidentally add different currencies (e.g., adding USD to EUR) without an explicit conversion step, preventing a common class of fintech bugs.

How does it handle regulatory compliance and auditing?

The skill implements patterns for immutable records and event sourcing. By ensuring transaction logs cannot be mutated and use structured tracing, it creates a reliable audit trail for regulatory requirements.

Implements high-precision financial logic and compliant transaction patterns for Rust-based banking, trading, and payment systems.

The Rust Fintech skill equips Claude with the expertise to architect robust financial software, ensuring maximum precision and regulatory compliance. It enforces critical domain rules such as using fixed-point decimals instead of floating-point numbers, implementing double-entry accounting, and maintaining immutable audit trails. Whether building a ledger, a payment gateway, or a trading platform, this skill provides the patterns and constraints necessary to prevent data loss and ensure financial integrity through specialized crates like rust_decimal and implementation patterns for idempotency and ACID transactions.
