SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

Circom-dev accelerates the development of zero-knowledge circuits by providing structured guidance, ready-to-adapt templates, and clear workflows for building, validating, and testing Circom-based zk circuits.

Core Features & Use Cases

  • Circuit Implementation: Design and implement arithmetic circuits using Circom.
  • Constraint Verification: Ensure constraints are correct, secure, and well-structured.
  • Witness Generation & Testing: Create witness calculators and run end-to-end tests, including common zk patterns such as Merkle proofs and range proofs.
  • Best Practices: Incorporates security considerations, debugging tips, and optimization guidance for robust circuits.

Quick Start

Install dependencies and run the included scripts to scaffold, compile, and test Circom circuits:

  • Install Node.js dependencies (npm install) in the assets directory.
  • Compile circuits with scripts/compile_circuit.sh <circuit.circom>.
  • Generate proving/verification keys with scripts/setup_keys.sh <your.r1cs>.
  • Verify a sample proof with scripts/verify_proof.js.

FAQPage Schema
How do I build and test Circom zk circuits end-to-end?▼

To build Circom zk circuits end-to-end, you compile the circuit, generate proving and verification keys, create a witness calculator, and run tests using snarkjs and Node.js workflows. The skill automates this entire process with provided scripts.

How do I generate and verify a zk proof with snarkjs and Circom?▼

To generate and verify a zk proof with snarkjs, compile your Circom circuit to an R1CS file, generate proving and verification keys via setup scripts, and execute a verification script to validate the generated proof.

What common zero-knowledge circuit patterns can I implement in Circom?▼

Common zero-knowledge circuit patterns you can implement in Circom include authentication, Merkle proofs, range proofs, and privacy-preserving patterns, supported by structured templates and constraint verification guidance.

Do I need Node.js and circomlib to develop zero-knowledge circuits?▼

Yes, you need Node.js and npm workflows to install dependencies and run tests, while circomlib provides essential library components for designing and compiling secure zero-knowledge circuits with Circom.

How do I ensure my Circom constraints are secure and correctly structured?▼

To ensure Circom constraints are secure and correctly structured, apply incorporated best practices for constraint verification, utilize debugging tips, and follow optimization guidance to prevent under-constrained circuits.

What is the best way to scaffold a zero-knowledge circuit project?▼

The best way to scaffold a zero-knowledge circuit project is using included scripts to compile circuits, generate keys, and run tests, accelerating development with ready-to-adapt templates and clear workflows.
