About MetaMask

We’re building for a future where the internet and world economy empowers people through interactions based on consent, privacy, and free association. Where both communities and individuals flourish. To accomplish that, we’re working hard to make web3 accessible for everyone.

Our browser extension and mobile platforms meet the needs of millions of users and developers across the world.

The MetaMask Dapp API Team Is Hiring

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, propose that users add and switch to a specific network, propose that 

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 can be built.
