About Cometh
Cometh is an enterprise-grade DeFi infrastructure provider. Its core business is a unified API that lets financial institutions integrate crypto custody, staking, trading, and payments into their own products. The platform abstracts away cross-chain complexity and smart wallet management, so clients can offer digital asset services without building blockchain tech in-house.
The main pain point Cometh addresses is the gap between traditional finance and decentralized finance. Enterprises face regulatory uncertainty, fragmented blockchain networks, and high engineering costs when trying to adopt DeFi. Cometh solves this by offering a regulated, audited infrastructure layer — it holds a MiCA/CASP license from the French AMF and ISO 27001 certification — while keeping the flexibility of self-custody and on-chain automation.
Its competitive edge lies in combining compliance with technical depth. The company has processed over 1.3 million transactions on Gnosis Chain using a non-custodial, multi-signature architecture where each client operates in an isolated account. Smart contracts are immutable and non-upgradable at the asset control layer, reducing attack surface. This makes it attractive to institutions that need both regulatory clarity and robust security.
In the past six months (March to September 2026), Cometh was acquired by Kaiko, a digital asset data provider. The acquisition created a full-stack compliance loop: Kaiko supplies BMR-authorized market data and indices, while Cometh adds MiCA-licensed on-chain execution and oracle services. This positions the combined entity as a one-stop infrastructure for regulated DeFi products. Cometh also continued its work on biometric authentication, which was originally funded by the Ethereum Foundation and integrated into the Safe ecosystem.
No major negative events were reported in the last two years, though the broader DeFi sector has faced security incidents that highlight the importance of Cometh's non-upgradable contract design.
Cometh, a French DeFi infrastructure provider, was founded in 2020 and specializes in smart accounts, chain abstraction, and regulated on-chain solutions. In December 2025, it obtained a MiCA/CASP license (No. A2025-008) from the AMF, becoming one of the first fully compliant on-chain infrastructure players in Europe. In early 2026, Cometh partnered with Everstake to enable institutional fiat-to-staking flows via IBAN and KYC/KYB, marking its expansion into regulated custody and staking services. Shortly after, Kaiko acquired Cometh, integrating its licensed infrastructure and engineering team into Kaiko's data stack. This acquisition positions Cometh as the execution layer for Kaiko's on-chain data products, while its MiCA license strengthens Kaiko's regulatory edge in Europe. These milestones highlight Cometh's evolution from a DeFi startup to a key regulated infrastructure provider bridging traditional finance and on-chain markets.
As a Web3 data analyst, I assess Cometh's key developments over the past six months (2026-03-01 to 2026-09-01). The most significant event is Kaiko's acquisition of Cometh, announced on May 20, 2026. This marks Kaiko's fourth acquisition and creates the only independent, MiCA-regulated provider of end-to-end data infrastructure for digital assets. Cometh holds a MiCA/CASP license (AMF No. A2025-008, granted December 2025) and ISO 27001:2022 certification, which are critical for institutional compliance. The acquisition was cleared by both the AMF and ACPR. Cometh's team, including its expertise in smart contract wallets, account abstraction, and cross-chain integrations, will remain intact, though CEO Jérôme de Tychey will depart. Looking ahead, the official roadmap focuses on building "compliance oracles" that meet both BMR and MiCA standards, bridging Kaiko's data and index capabilities with Cometh's on-chain execution technology. This will support tokenized securities, regulated stablecoins, and repo workflows on networks like Canton and Stellar. The combined entity will continue developing Cometh's DeFi products with a stronger data orientation, targeting institutional clients in the EU and Asia-Pacific who require licensed data infrastructure for on-chain deployments.
