OpenBlock DApp SDK

OpenBlock SDK is an open-source SDK that allows you to connect your DApps to our users, their assets and NFTs. We currently support major EVM chains, Aptos, Starcoin and more. Login to openblock.com for more details.

Introduction

• OpenBlock is a next-gen on-chain wallet committed to MPC protocol, keyless, seedless, and pushing security limits through distributed credentials and wallet recovery mechanisms.
