Introduction

🔐 Sigmate – The Ultimate Full-Stack Multisig Wallet Solution for Web3

In the world of decentralized finance, security and collaboration are no longer optional — they are essential. Sigmate is a next-generation, production-ready multi-signature wallet platform designed to meet these exact needs. Whether you’re building a DAO, managing a community treasury, or securing startup funds, Sigmate empowers teams to manage digital assets with trust, transparency, and control.

🧠 What is Sigmate?

Sigmate is a full-stack decentralized application (DApp) that enables multi-owner wallets with advanced approval mechanisms. Every transaction goes through a proposal, review, and approval process — ensuring that no single user has unilateral control. This approach protects funds from misuse, human error, or malicious intent, and reinforces collective governance, especially in crypto-native teams and projects.

With React.js and Next.js powering the frontend, a robust Node.js + Express.js backend, and secure Solidity-based smart contracts, Sigmate offers a complete, modular, and developer-friendly solution you can deploy instantly on Ethereum, Polygon, Binance Smart Chain, or any EVM-compatible chain.
