FastBridge
FastBridge is a unified cross-chain bridge built by Avail. Move and swap tokens from multiple chains to any supported destination in a single transaction, with no switching networks, no managing gas, and no waiting.
Overview
FastBridge is a unified cross-chain bridge, powered by Avail, which allows users to combine balances from multiple chains into a single transaction. Instead of bridging assets one chain at a time, FastBridge aggregates your USDC, USDT and ETH from across chains and delivers them to any destination in seconds.
The protocol supports major assets like USDC, USDT, and ETH, enabling users to consolidate distributed liquidity and deliver it to a destination chain within seconds. Additionally, FastBridge introduces gas abstraction, allowing users to pay transaction fees using stablecoins rather than holding native tokens on each source chain.
Built on Avail’s data availability layer, FastBridge benefits from a scalable and secure modular infrastructure, making it a robust solution for cross-chain interoperability and liquidity aggregation.
The Problem
Blockchain ecosystems are highly fragmented, with liquidity and assets distributed across multiple chains. Traditional bridging solutions require multiple sequential steps, increasing costs, latency, and risk exposure.
