Building the trust infrastructure for blockchain.
Particle CS develops technology that helps people, teams and software use blockchain with clearly defined authority and enforceable controls.
A valid signature isn’t the whole decision.
A payment can be correctly signed and still go to the wrong place. The same is true of any operation — an amount beyond what was intended, a change nobody approved. As more participants can act, what they’re allowed to do matters as much as who signed.
Make the rules part of execution.
Every operation starts as an intent — a person, an application or an AI agent asking for something to happen. Before it executes on the blockchain, the controls check who is asking, what they may do and under which conditions.
A platform to operate. A protocol to build on.
Run governed accounts in the Platform, or build the same controls into your own application with the open-source Protocol. The rules are enforced the same way in both.
Bloxchain Platform
A web app for your team’s on-chain accounts. Connect a wallet, decide who can do what, and approve requests in one place. The rules are enforced on-chain.
Explore the Platform →$ npm install @bloxchain/sdk @bloxchain/contracts viemBloxchain Protocol
Open-source building blocks for your own smart contracts: roles, approvals and time delays. Add them to your EVM app and manage them with our TypeScript SDK.
Explore the Protocol →Wherever responsibility is shared.
Treasuries, applications, digital assets and automation — anywhere more than one person or program can move assets or change the rules.
Hands-on help from the people who build it.
Bring us one real workflow — a treasury flow, a governance change, an agent’s permissions — and we’ll help you get the controls right.
Open by design, independently reviewed.
Security should be something you can check.
Our code is public, our core contracts are independently audited, and we’re clear about what the controls do — and what they don’t.
