Arkis x Spearbit

Arkis, the institutional prime broker for digital asset markets, has partnered with Spearbit, the security research firm behind reviews for Morpho, Coinbase, Optimism, and Liquid Collective, to create the first fully verifiable, tamper-proof digital provenance for institutional smart contracts.

Every smart contract Arkis runs will now carry that provenance: a complete, signed record of how the code was produced and who reviewed it, bound to the exact version that goes live. Spearbit becomes Arkis’s strategic security design partner and a required signer on every production release.

Arkis has built this verification directly into how its software ships. Each release carries a cryptographic signature from everyone who produced and verified it: the developer who wrote the code, the Arkis infrastructure that compiled it, and Spearbit, whose signature confirms the exact code it reviewed. Every step is signed, so the record is tamper-proof: any later change breaks the chain and is immediately visible, and nothing can be swapped in without every party signing again. Because the record is cryptographic, any counterparty can verify it independently, at any time.

“We have given Spearbit a real role in our release cycle: they not only audit our code, but their sign-off decides whether a release goes live. Audit is not a document anymore, it becomes an integral part of delivery that can block the entire release. This is the standard we intend to keep pushing, because verifiable security is how trust in this market gets built.”

Aleksandr Kopnin, CTO, Arkis

Spearbit’s signature is a mandatory condition of contract upgrades: no Arkis contract reaches production without their independent attestation, and they put their name on each release. Both firms intend this to become a standard for how institutional infrastructure is shipped.

“This is a direction we wanted to push, and Arkis gave us the place to prove it. Our signature is now an attestation of the exact code we reviewed, so anyone can confirm that what runs in production is what we approved. We are glad to take this on together with Arkis, and to start working with other players who want to hold their software to the same standard.”

Arkis has deployed more than $200M in institutional credit with zero bad debt since 2022, across multiple market cycles. The partnership with Spearbit extends that record to how the system itself is built and verified.
