DogeOS, an application layer for Dogecoin, has launched a public testnet built around a zero-knowledge rollup (scaling system that proves computations efficiently) to support EVM-compatible smart contracts (Ethereum-style programmable applications) on the network. DOGE will pay transaction fees, while applications could include trading, lending, stablecoins, prediction markets and games whose state settles to Dogecoin. The network currently relies on a trusted execution environment, validators and a permissioned sequencer. Dogecoin itself does not yet verify the rollup's zero-knowledge proofs; bridge state transitions instead require valid proofs, signatures from most validators and a TEE signer. A proposed Dogecoin Core upgrade could eventually let miners verify execution proofs directly, but it has not been implemented. The launch gives developers a live environment for testing, with a mainnet timeline to be shared after further development milestones. The team behind MyDoge raised $6.9 million from a round led by Polychain Capital in May 2025 and later submitted the proposed Core upgrade. DOGE traded around $0.094 at publication, down 60% over the past year.
