Midpoint is a platform for Ethereum developers that provides many different kinds of off-chain infrastructure with one simple API. With a single API call, developers set up "midpoints" - specifying a set of off-chain actions to be triggered from on-chain events. Midpoints can be oracles that query APIs based on requests from chain, data bridges to pass arbitrary messages between chains, data feeds to stream off-chain data back on-chain, and much more. The Midpoint dashboard provides a visual interface to help with creating these workflows. Midpoint is free to use!
