Multichain is the ultimate Router for web3. It is an infrastructure developed for arbitrary cross-chain interactions.
  • It enables assets transfers between any two or more chains.
  • It can work with pre-existing assets on blockchains, by using liquidity pools for those assets.
  • It can also work with Bridged assets smart contract, where Multichain is responsible for minting assets on chains. This allows a generalisation of Bridges, so that assets are not restricted to having to return to their source chain before being sent to another chain. This makes for a cost effective solution for users, especially if the asset originated on Ethereum.
  • The Router can include both native and Bridged assets. This allows inclusion of assets that might have been generated with a third party bridge (though we would need to understand what bridges were originally used).
