Stackup: Self-Custody Meets Seamless Web3 Onboarding

Stackup – Web3 Smart Wallet Toolkit with Gasless UX and Team Access — Stackup Official Logotype

What Is Stackup?

In the modern crypto era, self-custody wallets are a cornerstone of digital sovereignty. Unlike custodial solutions that require intermediaries or centralized platforms to hold and approve your funds, a self-custody wallet puts you fully in control.

Stackup is an open-source toolkit designed to simplify the development and deployment of smart contract wallets using account abstraction. Built by veterans from Coinbase and Trust Wallet, Stackup bridges the gap between Web2 finance and Web3 infrastructure, offering a user-friendly, secure, and scalable solution for developers, enterprises, and end users alike.
