MyCrypto

MyCrypto is a free, open-source, client-side interface for managing Ethereum accounts and interacting with the Ethereum blockchain. Founded in 2015, it is a non-custodial wallet — private keys never leave the user's device — supporting hardware wallets, Web3 and browser wallets, and offline transaction signing. In February 2022 MyCrypto was acquired by ConsenSys to consolidate with MetaMask and unify the Web3 wallet experience. MyCrypto ships no public REST API; its developer surface is the open-source application codebase and the JavaScript/TypeScript libraries (eth-scan, ethereum-blockies-base64, asset mappings) published under the MyCryptoHQ GitHub organization.

MyCrypto is profiled on the APIs.io network. Tagged areas include Company, Wallets, Ethereum, Blockchain, and Cryptocurrency.

MyCrypto’s developer surface includes documentation, support, and 9 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/mycrypto: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
