Cometh primary-source snapshot

Fetched: 2026-04-25 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 is no longer presenting itself as only a wallet SDK; the homepage foregrounds custody, staking, trading, and payments for businesses
  • The site repeatedly pairs technical claims like smart accounts and chain abstraction with regulated/compliance-oriented messaging
  • A live showcase product, Louis.finance, is linked as an example of what the stack enables in practice

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 landing page:

  • The docs make the target audience explicit: fintechs, asset managers, and corporates rather than retail wallet users
  • The public documentation is currently deepest on the smart-wallet/account-abstraction stack, while the broader DeFi-as-a-Service API layer is described as still coming soon

3) SDK Core and Connect materials

Source: https://docs.cometh.io/sdk-core.md Source: https://github.com/cometh-hq/connect-sdk-4337

Selected excerpts from the docs and repo:

This Core version of the Cometh Connect SDK 4337 provides the essential functions for managing smart accounts. It supports various authentication providers such as EOA, Magic, Web3Auth, Turnkey, and Privy.

Cometh Connect is an SDK that enables applications to provide their users a smart wallet controlled with biometrics.

Instant wallet creation via account abstraction.

Gas fees sponsoring via cometh paymaster.

Additional signals from the SDK materials:

  • The strongest product detail is around account abstraction, biometric/passkey style onboarding, gasless UX, recovery, and Safe-based smart accounts
  • Public repos across web and mobile suggest Cometh is shipping real developer tooling rather than only marketing regulated infrastructure

4) Bundler API

Source: https://docs.cometh.io/bundler/bundler-api.md

Selected excerpts from the docs:

A Bundler, as introduced by ERC-4337, is a pivotal infrastructure component enabling account abstraction on Ethereum Virtual Machine (EVM) networks.

Its core function is to manage a mempool of User Operations (UserOps), aggregating them and submitting them to an Entry Point Contract for on-chain execution.

Additional signals from the Bundler docs:

  • Cometh documents concrete ERC-4337 RPC methods like eth_sendUserOperation, eth_estimateUserOperationGas, and receipt/status lookups
  • This materially strengthens the case that Cometh operates production AA infrastructure, not just front-end wallet components

5) Paymaster API

Source: https://docs.cometh.io/paymaster/paymaster-api.md

Selected excerpts from the docs:

Paymasters are smart contracts designed to facilitate transaction sponsorship.

They allow third parties to sponsor the gas fees for transactions, enabling users to interact with the blockchain without having to pay for gas themselves.

Additional signals from the Paymaster docs:

  • The docs expose a concrete sponsorship model around approved contract addresses, supported networks, API endpoints, and monthly invoicing
  • This makes Cometh look like an operational gas-sponsorship/control-plane vendor, not only a developer SDK shop

6) GitHub organization

Source: https://github.com/cometh-hq

Selected signals from the public organization page:

  • Public repos include Connect SDK variants, keystore components, and iOS/Android 4337 SDK work
  • Repository activity supports the view that Cometh is still actively investing in account-abstraction infrastructure as a core surface

Notes

  • This pass did not locate a classic whitepaper or litepaper.
  • Cometh appears best categorized as regulated DeFi infrastructure layered on top of a smart-account / ERC-4337 developer stack.
  • The strongest primary materials were the official site, docs portal, and public repositories.
