THIRM is a protocol that allows users to access cryptocurrency assets between multiple blockchains.
With the rise of DEFI many dApps are being built on blockchains, but these blockchains run on different codebase which makes using the dApps from blockchain A impossible on blockchain B. While many dApps are being ported across blockchains, they are limited and might not function the same way as intended on the main blockchain.
Some blockchians don't support dApps at all (Bitcoin and Litecoin are good examples).
So what if a Bitcoin user wants to use a DEX (decentralized exchange) on Ethereum? How will he use these dApps? They need a service that will allow them to use their Bitcoin on any other blockchain.
Here comes THIRM, a Crosschain Bridge that allows many blockchains to interconnect.
