The brief

Can trust between strangers be built without a central party? Anchor tests the idea as a game: every player has a permanent on-chain identity, agreements between players require an ETH stake and are logged forever, and whoever keeps their agreements builds a reputation that unlocks new opportunities.

How it was built

Two contracts in Solidity, Identity and Agreements, tested with Foundry. A NestJS backend simulates the world and generates missions continuously, with Prisma for storage. The client is a Next.js app with wagmi for wallet and signing. Everything starts locally with one script against Anvil.

What was built

  • Identity and agreement contracts
  • Reputation engine and world simulation
  • API for agreements, missions and reputation
  • Client with wallet connection
  • Docker Compose for the full stack
