Best Blockchain APIs for Ethereum

A new paradigm for cross-chain experiences that seamlessly connects users with applications. End-users can benefit from the fastest and lowest-cost bridging. Developers can benefit from a streamlined interoperability. Cross-chain Intents are a limit order and an action to be executed. Intents replace explicit steps with user outcomes. This allows relayers to compete for the best execution path. Unlike complex trusted messaging solutions, Across connects users with dapps through intents and not just blockchains to other blockchains. Developers need only embed a standard action in protocol actions to create seamless experiences across chains.
