We build production-grade, open-source tooling for the Circles protocol-architected to be fully decentralized and permissionless, so anyone can run and extend it.
Our focus is deterministic Rust services, smart contracts, and ergonomic developer / user interfaces that make trust-based money programmable at scale.
| Repository | Domain | Purpose |
|---|---|---|
| circles-rs | Rust crates | Path-finding engine & flow-matrix generation for trust graphs |
| subi | Solidity · Rust · TypeScript | Complete subscription stack: Safe module contracts, Silverback automation bot, and a Next.js dashboard |
| subi-contracts | Solidity | Minimal Safe module for permission-less claiming of recurring payments |
| subindexer | Rust | Event indexer + API exposing redeemable-subscription state (PostgreSQL / GraphQL) |
| subi-garden | SvelteKit | Reference wallet demonstrating Circles sign-in & SDK usage |
| redeem-rs | Rust | Headless redemption bot that listens to subindexer events and triggers subscribe / redeemPayment transactions |
| redeem-ts | TypeScript · Tenderly | Cloud-hosted redemption bot (Tenderly Action) performing the same logic in a Node.js environment |
