# Retro Bridge

> Multichain made easy. All chains, single app

Retro Bridge enables asset transfers between EVM and non-EVM networks using concentrated liquidity pools instead of smart contracts.

Retro Bridge transfers assets between 41+ blockchain networks, including EVM and non-EVM chains. It uses concentrated liquidity pools on each chain rather than smart contracts for transactions. Retro Bridge supports several functions, including regular bridging, multi-destination transfers, cross-chain swaps, and a testnet bridge. Users can earn points through platform activity that may contribute to future rewards.
