Composable smart contract interoperability on Polkadot

Rust Developer

t3rn is a hosting platform for smart contracts, that enables trustless, interoperable execution and composable collaboration.

The t3rn protocol renders smart contracts blockchain agnostic, meaning they can instantly execute on multiple blockchains. Smart contracts can be uploaded as they are and t3rn will host and securely execute them across independent blockchains, breaking the barrier to serving users across industries and blockchain platforms.

Executed smart contracts are stored in t3rn’s decentralised repository and can be used by anyone, either for free or on a pay-per-use model that rewards the developer. t3rn brings full smart contract interoperability and composable collaboration to the Polkadot ecosystem and beyond.
