I’ve been building a new credit‑market primitive called Credit Units (CUs) — a standardized, atomic representation of credit exposure that can be issued, traded, and settled on‑chain.

The aim is to create a simple, transparent building block for credit markets, without reproducing the opacity and fragmentation of legacy credit infrastructure.

What’s live now

• Public Solana devnet deployment • Cross‑wallet trading (buy in one wallet, sell in another) • Deterministic issuance and settlement logic • Seller‑maintenance invariant enforced on‑chain • Next.js UI + Rust/Solana backend • Supabase for activity history • Clean, documented architecture

Why this exists

Credit markets today are:

• opaque • slow • fragmented • inaccessible to most participants

CUs are an attempt to provide:

• standardized credit exposure • transparent pricing • atomic settlement • open participation • a foundation for indices, baskets, and structured products

Think of it as credit exposure as a first‑class on‑chain asset, rather than a derivative bolted onto an AMM.

Who I’m looking for Not testers or airdrop hunters — the system already works.

I’m looking for: • engineers who enjoy building financial primitives • Solana/Rust developers • people interested in credit, risk, or market structure • contributors who want to help shape an early system

Try it out

Repo: https://github.com/zippy2261-lgtm/credit-units Live devnet UI: https://credit-units-ui.vercel.app Docs: https://pukw8vrkvrdfqd4h.public.blob.vercel-storage.com/PUBL...

Feedback that would be most helpful

• architecture and invariants • UX flow • economic logic • potential integrations • edge cases • contributor experience

This is early, but real. If you’re interested in credit markets, Solana, or financial infrastructure, I’d appreciate your thoughts.
