Across Protocol Becomes Fastest EVM Bridge With Intent Architecture

Across Protocol has processed $4.8B in bridge volume in Q1 2026 using an intent-based architecture where professional relayers (called "fillers") pre-fund transfers on the destination chain and are reimbursed by the protocol's hub contract on Ethereum. The result is sub-2-second settlement times for most L2-to-L2 routes.

On-Chain Context

The hub-and-spoke model concentrates settlement risk in the Ethereum hub contract but eliminates the trust assumptions of lock-and-mint bridge designs. The protocol's UMA-based optimistic verification allows disputes to be raised within a 2-hour challenge window if a filler provides incorrect funds.

Risk & Opportunity Assessment

Filler competition is healthy. There are currently 18 active fillers on Across, creating a competitive market for bridge pricing. Average bridge fees have declined from 0.12% to 0.06% over the past 6 months as filler competition intensifies and capital efficiency improves.

"This development underscores the maturation of DeFi infrastructure — protocols are increasingly competing on execution quality rather than raw liquidity depth."

The broader market context remains constructive. Total value locked across DeFi stands at $148.2B, up 12.4% month-over-month, driven primarily by renewed institutional participation in structured yield products.

Comparative Protocol Analysis

When benchmarked against competitors, the divergence in execution strategies becomes clear. While some protocols have prioritised simplicity and gas efficiency, others are betting on composability and hook-based extensibility as the primary moat.

For DeFi participants, the actionable takeaway is to monitor on-chain flow data over the next 72 hours. Capital allocation shifts of this magnitude typically produce follow-on effects across correlated pools within three to five blocks of the initial transaction.
