Deep Dive
1. Bridge Everything Upgrade (25 November 2025)
Overview: This major user experience upgrade allows users to bridge any token to any token across supported chains in one transaction. It also overhauled the interface with better search and navigation.
The upgrade integrates with 0x, LiFi, and Uniswap for routing, making the bridge more powerful. The new UI includes features like searching for chains and tokens by name, ticker, or contract address.
What this means: This is bullish for ACX because it makes the bridge significantly easier and more flexible for everyday users. They can now swap between any assets across chains without multiple steps, which could attract more volume and solidify Across's competitive position.

2. Non-EVM and Prefill Support Proposal (21 January 2025)
Overview: This community-approved proposal authorized technical changes to let Across support non-EVM blockchains (like Solana) and enable "prefill" transactions, where users receive funds instantly.
The upgrade required breaking changes to event names and method signatures (e.g., FilledV3Relay became FilledRelay) and introduced new logic to handle non-EVM addresses and out-of-order transactions.
What this means: This is bullish for ACX as it unlocks growth in entirely new ecosystems, tapping into new user bases. The ability for instant fills also positions Across as a leader in cross-chain user experience, a key differentiator.

3. V4 Architecture with ZK Proofs (21 July 2025)
Overview: Across V4 introduced a new backend architecture that combines intents with zero-knowledge proofs (ZKPs) to verify transactions trustlessly on any destination chain.
The system uses Succinct's SP1 to generate ZK proofs that a message hash was finalized on Ethereum. This eliminates the need for custom, chain-specific adapters, creating a universal and secure verification pipeline.
What this means: This is bullish for ACX because it makes expanding to new blockchains faster, cheaper, and more secure. By reducing technical overhead and centralization risk, it strengthens the protocol's long-term foundation and scalability.

Conclusion
Across Protocol's development is sharply focused on chain abstraction—removing complexity to let users move any asset anywhere instantly. With these upgrades, it's building a formidable moat in the competitive bridging space. How will its growing integration network, like MetaMask and PancakeSwap, further accelerate adoption?
