Across Overview

The crypto industry is becoming increasingly fragmented as more rollups and L1 chains launch, siphoning users and liquidity from other ecosystems while creating inefficiencies. To help combat against siloed ecosystems, many interoperability solutions have launched to make cross-chain transacting more intuitive. Many of these solutions are based on cross-chain messaging or multi-chain liquidity pools. Most solutions have struggled to solve for speed, cost, and security, often making tradeoffs in one category for another.

Across is an interoperability protocol powered by intents. Across has three main products to support blockchain interoperability:

• Across Bridge – an intents-based bridge where users can transfer assets quickly and securely across seven EVM chains.
• Across+ – a bridge abstraction framework that allows dapps to integrate Across into their protocol, enabling bridging and protocol actions within the same transaction.
• Across Settlement – a settlement layer built for cross-chain intents.

Across Bridge

Many cross-chain messaging designs are ineffective due to slow transfer finalization and high costs, while other designs like cross-chain AMMs make security tradeoffs. Across uses an intents-based design where users specify the outcome of a transaction ra...
