Vyper

Pronunciation

[vī-pər]

Analogy

Vyper is like writing smart contracts in a secure subset of Python—you trade some syntactic flexibility for stronger safety guarantees.

Definition

A Python‑inspired, strongly‑typed language for that emphasizes simplicity, security, and auditability.

Key Points Intro

Vyper enforces security and simplicity through:

Key Points

No inheritance: Reduces complexity and attack surface.

Bounds & limits: Explicit loops only, no infinite gas consumption.

Strong typing: Prevents type ambiguity and hidden conversions.

Audit‑friendly: Minimal features for easier code review.

Example

A DAO contract written in Vyper manages membership and voting without complex inheritance hierarchies, making audits straightforward.

Technical Deep Dive

Vyper source is compiled via vyper‑cli to . It disallows modifiers, function overloading, and recursion. All variables must be declared with explicit storage locations. The compiler inserts overflow checks and bounds for loops. JSON is generated for contract interfaces.

Security Warning

Limited library ecosystem means developers must implement utilities themselves—bugs in custom code can be critical.

Caveat

Lacks some high‑level features of , making certain patterns more verbose.
