muzix: an OP Stack L1 for music finance

Why we keep coming back to music

kcolbchain's first deep involvement with music-on-chain was Create Protocol, in the previous cycle. That work ended when the market moved on, but the underlying problem didn't: artists wait six to eighteen months for royalty checks that lose 3-8% to FX and bank fees on the way. Catalogs are valued by gut and sold whole. Rights data lives in incompatible spreadsheets across labels, publishers, PROs, and DSPs. Micro-payments below a cent never reach the artist because the rails can't carry them.

Each of those problems is a solved problem in DeFi. Stablecoin settlement, atomic splits, tokenized cash flows, micro-payments — these primitives exist and work. They just haven't been wired together for music. muzix is the wiring.

Not a music app — a layer

The single most important framing: muzix is not a Spotify competitor and is not a fan-token marketplace. It's the settlement and tokenization layer that those things plug into. The customers are music businesses (labels, distributors, DSPs, financial-product builders), not end-users.

Concretely: if you're a distributor today and you want to pay 50,000 artists across 80 countries every month, you cobble together an army of payment processors and currency converters. With muzix, you settle once on-chain in MUSD and the splits execute atomically. Same gas cost whether the artist is in Lagos or Los Angeles.

Four capabilities

The muzix L1 exposes four primitives that together cover the music-finance surface:

• Tokenize — catalogs, songs, rights, and royalty splits as on-chain assets. Programmable, tradeable, composable.
• Finance — royalty advances against verified streaming revenue, catalog-backed lending, future-revenue swaps, music index funds.
• Settle — MUSD stablecoin (built on stablecoin-toolkit), real-time royalty splits, instant cross-border, viable micro-payments down to $0.001.
• Connect — DSPs report streaming data via oracles, labels and distributors settle through MUSD, rights data lives in a shared on-chain registry.

Why OP Stack

We considered three architectures: a generic L2 (Base), a sovereign L1 (custom Cosmos chain), or an OP Stack L1 with Ethereum settlement. OP Stack won on five dimensions:

• EVM compatibility — every existing wallet, tool, and indexer works out of the box
• L2 economics — micro-payments are viable at $0.001 per tx
• Ethereum security — settlement on L1 instead of standing up a new validator set
• Superchain composability — interop with Base and Optimism is native
• Battle-tested — Base processes billions in volume on the same stack daily

What's shipping now vs later

muzix is in Phase 1 (foundation): OP Stack testnet deployment, MUSD contracts, basic royalty split contract. Phase 2 is tokenization (catalog tokens, fractional ownership, rights registry). Phase 3 is the oracle + finance primitives. Phase 4 is ecosystem (SDK, first artist onboarding, DSP pilot, mainnet).

Architecture is published and the repo is open. Contributions welcome — particularly Solidity (contracts), Go (OP Stack node), TypeScript (SDK), and music-industry domain expertise.
