Across Protocol Automates Bridge Transfers with New SDK Package
Across Protocol has become one of the most active intent-based bridges connecting Ethereum to its Layer 2 network, settling more than $27.5 billion in transfers across 17.3 million individual deposits for over 4 million users as of mid-2025.
The protocol's unified Swap API now routes transfers across 24 chains, including Ethereum mainnet and major rollups like Arbitrum, Base, Optimism, and Polygon. However, manual bridging is not scalable in 2026 due to the complexity and time-consuming nature of the process.
To automate bridging, Across provides a SDK package that allows developers to create scripts using Node.js. The script fetches a live quote, executes a deposit, confirms the fill, and handles failed calls. This approach reduces settlement times to around two seconds for typical transfers and enables teams to move funds regularly across chains.
