Job Summary

Empowering developers to deliver great decentralized user experiences is at the heart of MetaMask’s purpose. From the beginning, we have done so by providing the web with an API that allows any developer to turn their site or web-app into a decentralized app connected to the blockchain.

The MetaMask Dapp API allows dapps to do things like: propose transactions to users, propose to users that they approve an address to transfer their tokens (this is how uniswap works), access the address of the users current account, use keys in MetaMask to help users encrypt and decrypt messages, propose to users that they sign specific messages, access the connected node/provider and call all methods on the Ethereum RPC API, and to propose that users add and switch to a specific network.

To get a fuller picture of the current API, you can check out our documentation https://docs.metamask.io/guide/rpc-api.html#table-of-contents

By improving and expanding this API, we can make entirely new types of decentralized user experiences possible. There is also much work to do to make this API accessible for the many new developers joining our space.

We are hiring engineers to join our Dapp API team and help us build the platform on which the world’s most exciting dapps will be built.
