TL;DR:
- Avail launched FastBridge, a unified bridge that aggregates USDC, USDT and ETH balances from multiple chains in a single transaction.
- The tool is powered by Avail Nexus, an intent-based coordination layer that abstracts multichain routing into a single action.
- FastBridge allows fees to be paid in stablecoins, so users don’t need to hold native gas tokens on each source chain.
The DeFi ecosystem scatters user capital across five, six or more networks simultaneously. Ethereum, Arbitrum, Base, Optimism and next-generation chains like MegaETH or Monad are common destinations for active liquidity, and every new yield tool demands repeating the same manual process: identifying which network holds enough balance, switching networks, executing a bridge, paying gas and waiting for confirmation. FastBridge, Avail’s new product, was designed to eliminate that workflow entirely.
FastBridge is a unified multichain bridge that reads the user’s balances across all compatible chains simultaneously, calculates the optimal combination of sources and executes the transfer in a single transaction. The result arrives at the destination chain in seconds, regardless of how many source networks are involved.
Avail: How Does FastBridge Work?
FastBridge operates on Avail Nexus, an intent-based coordination layer that abstracts the complexity of multichain routing. Rather than deciding from which chain to bridge, the user simply specifies how much is needed and where they want it to arrive. The system calculates the rest in real time and allows specific source chains to be deselected if the user prefers not to touch certain balances.
One of the tool’s most significant features is gas abstraction: users don’t need to hold native tokens on each source chain to cover fees. FastBridge accepts fee payments in USDC or USDT, eliminating one of the most common drop-off points in traditional bridging flows.
What previously required three or four separate transactions, with network switches and multiple confirmations, is reduced to a single signature. FastBridge displays a full breakdown of which chains will contribute funds and in what proportion before the user confirms, providing high transparency without sacrificing simplicity.
Who Is It Aimed At?
FastBridge targets specific profiles: users who rotate capital across protocols in search of the best yield, explorers of new ecosystems who need to position themselves quickly to capture first-mover advantages and any user with portfolios fragmented across multiple networks. According to Avail, every additional step in a bridging flow is a point where users abandon the process — not for lack of intent, but due to the accumulation of cumbersome steps. FastBridge aims to solve that problem by reducing the entire flow to a single action.
