I build quickly, learn from customers and improve the product.

I’m Anson Cheung, a founder and product engineer. I build working products quickly, test them with customers and use their feedback to decide what changes next. At Lit Protocol, I was team member #5 and led the SDK team.

Open to talks with investors, partners and early teams. I also take on founding roles and product work.

Build, test, learn, repeat

  • Understand the problem. I speak with customers about the task and the problem they need to solve.
  • Build a small version. I choose an assumption to test and use AI to build a working version quickly.
  • Test with customers. Customers try the product. I speak with them to find what works and what needs to change.
  • Improve and repeat. I decide what to keep, change or remove, then release the next version.

AI helps me test ideas sooner. I own the product decisions and check the design, code and release.

Agent-Native Spine

Used across my projects

Agent-Native Spine is the architecture I use across my projects. I define each product action once, with its input, permissions and scope. The app, HTTP API, CLI and MCP tools all call that same action, so people and agents get the same behaviour and the same rules.

  • Familiar sign-in for programmable wallets. SDK flows for Google, Discord and passkeys, with key creation, sessions and requested permissions.
  • A shorter path to running code. CLI and scaffolding to create, build, test and deploy Lit Actions.
  • APIs for new network generations. Network integrations and session-permission tools, with integration tests, from early networks through Naga and SDK v8.

What I changed at Lit Protocol
Four years as team member #5. How I turned distributed signing and encryption into an SDK that developers could use: sign-in, tools, network integrations and dashboards.

Based in Hampshire, UK. Muay Thai enthusiast: I led the university Muay Thai team as its president. Up for a little spar? Played Dota at school, then reached the top 5% in Heroes of Newerth (1850 MMR), a multiplayer online battle arena game like Dota. Occasionally stealth camping across the UK. Lately into all kinds of racket sports.
