Building the foundation of the onchain economy
We're a team of cryptographers, security engineers, and builders on a mission to make secure key management accessible to every developer.
Our Mission
Private keys are the foundation of every onchain interaction — and managing them securely is one of the hardest engineering challenges in crypto.
0xKey exists to solve this problem once, so that every developer building on Web3 doesn't have to solve it themselves. We build cryptographically secure, verifiable, and scalable key management infrastructure — so you can focus on your product.
From embedded wallets for consumer apps to automated signing for AI agents, 0xKey is the infrastructure layer for the onchain economy.
What we stand for
Security First
We build with cryptographic security as the foundation, not an afterthought. Every design decision is evaluated against the threat model first.
Verifiability
We believe in replacing blind trust with mathematical proof. Our code is open source and independently verifiable by anyone.
Developer Experience
Great security should be easy to build on. We invest heavily in APIs, SDKs, and documentation to make the right choice the easy choice.
Non-custodial by Default
We never hold user funds. Our infrastructure gives you the tools to build truly self-custodial products at scale.
Join the team
We're a small team of cryptographers, security engineers, and product builders — distributed and remote-first. If you care deeply about security and want to work on hard problems at the frontier of Web3 infrastructure, we'd love to hear from you.
