Tongo Documentation (Under Construction)

Welcome to the official Tongo documentation. Tongo is a confidential payment system for ERC20 tokens on Starknet, providing privacy-preserving transactions while maintaining auditability and compliance features. Tongo is heavily based on this paper.

Waring This documentation is under costruction. It is mostly done but we have to come back to round some rough edges. Use it wisely.

What is Tongo?

Tongo wraps any ERC20 token with ElGamal encryption, enabling private transfers while maintaining full auditability. Built on zero-knowledge proofs and homomorphic encryption over the Stark curve, Tongo enables users to transact with hidden amounts while preserving the ability to verify transaction validity.

Key Features:

  • No Trusted Setup: Built entirely on elliptic curve cryptography
  • Hidden Amounts: All transfer amounts are encrypted
  • Flexible Compliance: Global auditor support and selective disclosure

Getting Started

If you're a developer looking to integrate Tongo into your application, start with the SDK Quick Start.

If you want to understand the protocol and cryptography, begin with the Protocol Introduction.
