MetaMask API Specs

API Playground: https://metamask.github.io/api-playground/api-documentation

JSON-RPC API provided by MetaMask.

MetaMask dapp developers lack a formal RPC specification. This attempts to document which methods MetaMask supports in a way that's versionable, human-readable and machine-readable. It will improve the accuracy of documentation, API, and clients.

MetaMasks effectiveness as an enterprise-grade application platform depends on its ability to provide a reliable and predictable developer experience.

To Add Methods

Add new methods as files to the methods/ folder.

Add those new files to the metamask-openrpc.json file.

You can then run yarn run build to generate the output file again.

To test the result, you can paste the resulting file from dist/build/metamask-openrpc.json into the OpenRPC playground and view the result.
