Cometh company primary-source snapshot
Fetched: 2026-08-09 UTC
1) Official homepage
Source: https://cometh.io/
Selected excerpts from the official site:
The DeFi Infrastructure for Businesses
One API to integrate DeFi custody, staking, trading and payments. Enterprise-grade compliance, Web3 flexibility.
Additional signals from the homepage:
- Cometh presents the stack as one operator-packaged business surface rather than only a wallet SDK
- The homepage foregrounds regulated positioning, full API infrastructure, and institutional use cases rather than retail wallet UX
- A current banner says
Cometh Joins Kaiko, which makes the parent-company boundary newly relevant to how the stack is marketed and likely sold
2) Official docs landing page
Source: https://docs.cometh.io/
Selected excerpts from the docs:
Cometh is building the DeFi-native Banking-as-a-Service (BaaS) infrastructure for Europe.
Our platform enables fintechs, asset managers, and corporates to launch regulated crypto services—custody, staking, swaps, and more via a unified API and smart wallet infrastructure.
We combine a fully composable tech stack (Crosschain Safe, ERC-4337) with a MiCA-aligned regulatory perimeter.
Additional signals from the docs:
- The target audience is explicitly institutional rather than retail
- The docs make the split between a broader regulated business platform and the more concretely documented Connect / account-abstraction stack visible
Crosschain SafeplusERC-4337are framed as building blocks, which strengthens the case that Cometh is an operator and packaging layer rather than a standalone protocol primitive
3) Bundler API docs
Source: https://docs.cometh.io/bundler/bundler-api.md
Selected excerpts from the docs:
We support multiple chains for the bundler service, you just need to modify the chainId and apiKey to your network.
Additional signals from the Bundler docs:
- Cometh operates production bundler endpoints under its own hostname
- API-keyed access and supported-network policy are part of the operator boundary
- The docs expose concrete ERC-4337 RPC methods for submission, gas estimation, receipts, and supported entry points, which makes the control surface legible as infrastructure operation rather than only SDK guidance
4) Paymaster API docs
Source: https://docs.cometh.io/paymaster/paymaster-api.md
Selected excerpts from the docs:
To authorize the sponsorship of a given contract address, you need to add it to your sponsored addresses in the dashboard. From there, we will accept sponsoring transactions targeting this contract.
At the end of each month, you will receive an invoice with the total amount of gas fees covered.
Additional signals from the Paymaster docs:
- Sponsored-address and sponsored-chain management are dashboard- and secret-gated company-run control surfaces
- Gas sponsorship is explicitly tied to billing workflow and license limits, not only smart-contract logic
- Cometh operates the paymaster endpoints and decides the admission path for sponsored traffic
5) Privacy policy
Source: https://app.cometh.io/privacy
Selected excerpts from the policy:
This Privacy Policy describes how cometh.io (“we,” “us,” or “our”) collects, uses, shares, and protects the personal information of users of our website and web application.
We are committed to respecting your privacy rights and complying with relevant data protection laws, including the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).
Additional signals from the policy:
- Cometh runs a web application with Google and GitHub sign-in plus email-linked account workflow
- The policy makes the company-side identity, account, and analytics layer explicit rather than leaving the stack as a pure smart-contract story
- Contact and compliance handling run through Cometh’s own support and legal shell
6) Kaiko acquisition announcement
Source: https://www.kaiko.com/news/kaiko-acquires-cometh-to-scale-mica-regulated-onchain-data-infrastructure
Selected excerpts from the announcement:
Kaiko today announced the acquisition of Cometh, a MiCA/CASP-licensed European provider of regulated financial services specialising in decentralised finance infrastructure.
Cometh holds a MiCA/CASP license (AMF No. A2025-008, granted December 2025), and ISO 27001:2022 certification.
The team operates mission-critical systems at scale, ranking among the most active transaction relayers on Gnosis Chain with over 1.3 million transactions executed to date under a non-pooled security architecture.
Every client operates through a segregated account with multi-party signing distributed across independent trust domains.
Additional signals from the announcement:
- By mid-2026 the Cometh operator boundary matters partly because it is no longer fully standalone; Kaiko is presenting it as part of a larger regulated onchain-data and execution stack
- The announcement makes relayer scale, segregated-account posture, and multi-party signing central operating claims rather than incidental implementation details
- MiCA/CASP licensing and institutional compliance posture are being used as primary product and go-to-market differentiators
Notes
- This pass did not find a classic whitepaper or litepaper.
- The strongest current materials are the official homepage, docs, dashboard privacy policy, and the Kaiko acquisition announcement.
- Cometh is best read as a company-run regulated wallet / account-abstraction / execution stack rather than as a neutral protocol primitive.
