Helixbox

Helixbox is a cross-chain asset bridge and DeFi terminal developed by Helixbox Labs, spanning Ethereum, Arbitrum, Optimism, Base, Linea, Polygon, Taiko and Blast. It serves traders and market makers who move assets between chains without wanting to maintain a separate route for every venue.

The design separates the underlying generic messaging bridge from the asset movement itself: the asset side runs on its own protocol, so a user interacts directly with a contract and a transfer settles in tens of seconds to a minute without heavy message passing. A smart account layer on top allows custom receiving addresses. A separate XToken bridge handles custody and cross-chain issuance, while a liquidity solver supplies counterparties for order-flow venues such as CowSwap and UniswapX.
