After processing over $17B in crosschain volume and collaborating with protocols like Uniswap, we're launching the Across Developer Toolkit to enable seamless crosschain integrations in any dApp.
With this launch, Across reiterates its position as more than a crypto bridge, evolving into a complete crosschain infrastructure provider. Our vision is to make bridging invisible. Users shouldn't think about bridging – they should just be able to interact with any dApp from any chain.
The current paradigm of sending users away to bridge assets, only to hopefully return later, creates unnecessary friction and significantly impacts user retention. By integrating Across directly into your application, users stay engaged with your protocol while bridging happens seamlessly in the background.
Crosschain Payments Accepted Here
The Across Developer Toolkit empowers any protocol to accept user transactions, irrespective of the origin or destination chains. Now your users can interact with your protocol from wherever they are, with bridging seamlessly handled behind the scenes.
Core Components
The toolkit consists of:
App SDK: A TypeScript SDK for providing useful abstractions on top of Across' smart contracts and quotes API.
API: An API for quote generation and transaction management
Documentation: Integration guides and reference materials
Key Capabilities
Native Bridging
Integrate Across's battle-tested bridging infrastructure directly into your application:
Crosschain Actions
Enable users to interact with your protocol from any chain without explicitly bridging first. For example, users can deposit directly into your Optimism-based protocol from Arbitrum:
See our GitHub repo for the full example
Use Cases
DeFi: Enable direct funding from any chain
NFTs: Allow minting from any chain
GameFi: Accept in-game payments across chains
Services: Process payments from any supported chain
Getting Started
