Who is building what across the three layers of "Doge DeFi" — DogeOS (zk app-layer), Dogechain (EVM sidechain), and DRC-20 / Doginals (native L1 inscriptions) — with official links, key people, capital, and every live opportunity. Documentation-first. Research-only.
The live story. An EVM + zkVM app layer settling to Dogecoin L1, built by the MyDoge team (Doge Labs), Polychain-backed. Still pre-mainnet on the Chikyū testnet. The stated App-Layer window Jun–Aug 2026 has now expired with no mainnet: re-checked 2026-08-26 — rpc.dogeos.com and rpc.mainnet.dogeos.com have no DNS, and the docs still list exactly one network (Chikyū, chainId 6281971, verified live). The official register has grown to 25 dApps.
A separate EVM sidechain (Polygon Edge, est. 2022). Once the home of "Doge DeFi," it is now DARK. The wind-down announced 2026-06-08 ran its ~60-day bridge window (closed ~2026-08-07); as of 2026-08-26 dogechain.dog returns no DNS records at all — site, docs, bridge and RPC are gone. Its epitaph: "adoption never scaled" — the bear case DogeOS must beat.
Native Dogecoin inscriptions (BRC-20-style) on L1 itself. ~$4.2B cumulative mcap (Q1'26), led by Doge Labs' wallet/marketplace/launchpad stack. Culturally hot, structurally separate from the EVM layers.
dogechain.dog has no DNS records at all. Layer B is past tense.blog.dogeos.com has not posted since 2025-11-20; metafide.io now 404s. Neither is a live signal any more.⚠ These three are constantly conflated in community chatter. They are technically and organizationally distinct. The same parent — Doge Labs — sits behind both Layer A (DogeOS/MyDoge) and Layer C (Doginals infra).
