Across

Across is a fast, low-cost cross-chain bridge powered by an intent-based architecture and UMA's optimistic oracle. Users consistently praise its speed (transfers under a minute), minimal fees (often under $1), and reliable performance across major EVM networks including Ethereum, Arbitrum, Optimism, Base, and Polygon, with recent expansion to Solana. The protocol is widely integrated into bridge aggregators like Jumper and Bungee, and has processed over $22 billion in volume. One review raised concerns about potential governance manipulation and limited token support, though the overwhelming majority describe it as a dependable, straightforward bridging solution that prioritizes simplicity and security over complexity.
