About
Hop Protocol is a scalable rollup-to-rollup bridge that lets users move tokens (notably stablecoins and ETH) quickly between Ethereum L2s using bonded liquidity and AMM-based swaps. It pioneered fast canonical-token transfers between Optimism, Arbitrum, and Polygon.

Across Protocol
Intent-based optimistic cross-chain bridge
Across is an intents-based bridge where users deposit on the origin chain and relayers fill on the destination in seconds, settling via UMA's optimistic oracle. It co-authored the ERC-7683 cross-chain intents standard and offers fast, low-cost stablecoin bridging across major L2s.
Cata Labs
Cross-chain liquidity protocol (Catalyst)
Cata Labs was a New York-based team building Catalyst, an open-source permissionless cross-chain liquidity protocol for modular blockchains that used a 'unit of liquidity' abstraction to enable atomic swaps of native assets across rollups and app-chains. The Catalyst AMM wound down and Cata Labs was acquired by LI.FI in February 2025.
Chainflip
Native cross-chain DEX and swap protocol
Chainflip is a decentralized cross-chain swap protocol with its own validator network and just-in-time AMM that enables native asset swaps across chains, including Bitcoin, Ethereum, Solana, and stablecoins, without wrapped tokens or bridges.
deBridge
High-performance cross-chain value transfer
deBridge is a decentralized cross-chain interoperability and liquidity network whose DLN (deBridge Liquidity Network) uses a solver-auction model to fill cross-chain trades with zero slippage. It supports 75+ blockchains and is a leading venue for fast stablecoin transfers, including Solana <> EVM routes.
Garden Finance
Fast, trustless Bitcoin cross-chain bridge
Garden Finance is an intent-based Bitcoin bridge that uses Hash Time Locked Contracts and a competitive solver network to move BTC to chains like Ethereum, Arbitrum, Base, Solana and HyperEVM in roughly 30 seconds with no custody risk. It suffered an ~$11M solver compromise in October 2025, which it said did not affect user funds.
Hashflow
Cross-chain RFQ trading and bridging
Hashflow is a request-for-quote (RFQ) DEX that supports cross-chain swaps with zero slippage by sourcing quotes from professional market makers, including cross-chain stablecoin trades. It uses signed price quotes rather than AMM pools for execution.
