DogeOS Opens Chikyū Public Testnet, Bringing Ethereum-Compatible Apps to Dogecoin
DogeOS launched public Ethereum-compatible testnet (Chikyū) for Dogecoin developers. Testnet enables building DeFi apps like trading, lending, stablecoins using test DOGE.

DogeOS testnet goes live
Dogecoin application layer DogeOS opened a public test network called Chikyū on September 30, 2026, and the testnet is Ethereum-compatible so developers can use familiar software to build applications on DOGE. The trial uses test DOGE to pay transaction fees while projects develop lending services, trading platforms, and a cryptocurrency-backed stablecoin.
DogeOS plans to back trust in its system with mathematical proofs and eventually have Dogecoin's own network check them. Dog eOS opened its public testnet on September 30 and the network works, but most announced applications remain plans rather than confirmed, usable products.
Security model and upgrade
DogeOS's first version depends on selected operators and hardware, including a permissioned sequencer that decides the order of transactions, with validators and a trusted execution environment checking proofs. Dogecoin's miners do not yet verify the application proofs themselves, and DogeOS wants to give them that role through an upgrade to Dogecoin Core.
DogeOS's proposal, called OP_CHECKZKP, would add a rule allowing computers on Dogecoin to check proofs that calculations performed elsewhere were correct. Dogecoin itself does not verify the rollup's zero-knowledge proofs and the current setup relies on validators, a trusted execution environment, and a permissioned sequencer.
Builders, funding, and open questions
DogeOS expects to add further developer tools, integrations and ecosystem projects as the testnet develops, and it listed teams building across trading, lending, stablecoins, launchpads, games and consumer apps. Jordan Jefferson said, "The testnet gives builders a place to turn ideas for Dogecoin into working applications," and Timothy Stebbing said, "L1 ledger purity must stay intact while we introduce utility one layer above."
DogeOS was founded by the team behind MyDoge and founder Jordan Jefferson told CoinDesk this month that attracting institutional investors required a stronger case for owning it after Bitwise said it would close its dogecoin ETF. The three U.S. dogecoin ETFs collected about $12 million in net inflows over nearly 10 months and recorded no net flows at all on 166 of their 199 trading days, while DogeOS has not announced a mainnet launch date.
