Kaspa’s KOB Testnet Brings Decentralized Limit Orders to KCC-20 Tokens
The developer preview runs entirely on Kaspa's base layer, using covenants and zero-knowledge proofs from the Toccata hard fork, with trade execution software anyone can run.
Key Takeaways
- Developer crono_walker released a testnet for KOB, a decentralized spot limit order book on Kaspa's base layer, on November 13, 2026.
- KOB matches buy and sell orders for KCC-20 tokens without a central party managing keys or trades.
- The contracts use covenants and zero-knowledge proofs from Kaspa's Toccata hard fork of June 30, 2026.
- KasperoLabs ran 23,874 hostile test transactions against the contracts before launch and found no bugs, though this was not a formal audit.
Developer crono_walker has released a testnet for KOB, a decentralized spot limit order book that runs directly on the Kaspa (KAS) base layer. The testnet went live in developer preview on November 13, 2026, with order matching for KCC-20 tokens and no central party in charge of keys or trades.
How the KOB Order Book Works
KOB lets traders set specific buy and sell prices for KCC-20 tokens, the asset format the testnet supports, according to BSC News' report on the KOB testnet launch. Nothing sits in the middle: no central authority manages user keys or matches orders. The software that executes trades can be run by anyone, so matching is open to any operator rather than one venue. Orders settle directly on Kaspa's layer-1 network.
Built on Toccata's Covenants and Zero-Knowledge Proofs
The system uses programmable features that arrived with Kaspa's Toccata hard fork on June 30, 2026, which brought native covenants and zero-knowledge proofs to the network. Those tools let contracts enforce spending conditions and verify computations without trusted intermediaries, the building blocks a limit order book needs on a base layer like Kaspa's.
Before launch, KasperoLabs ran 23,874 hostile transactions against the contracts without finding bugs, according to the same report. The developers note this testing was not a formal audit.
What Is Live Now
The testnet is still in developer preview, and no token on it carries value yet. A full mainnet version has not been dated. The next steps are expected to include more public testing and a formal review of the contracts before real value moves through the order book.
The network's own token economics also moved this month: Kaspa cut its block reward to 1.9445 KAS on November 4 in its monthly emission step. Traders can follow the market reaction on the Kaspa price chart, and KAS remains one of the leading proof-of-work networks.
