What is t3rn?

t3rn is a hosting platform for smart contracts, that enables trustless, interoperable execution and composable collaboration. Initially developed through the Web3 Foundation grants program, t3rn delivered a full proof of concept, before joining the Substrate Builders Program.

t3rn was created to address some of the core issues in blockchain technology, namely interoperability and how open-source software rewards contributors. t3rn will bring full smart contract interoperability to Polkadot and beyond, as well create an ecosystem that rewards developers based on how widely used their open-source contributions are.

We believe in trust-free collaboration. We are building an open, decentralized and community driven protocol for smart contract hosting and execution, where businesses and developers share solutions and grow the network’s value exponentially.
