What is t3rn?

t3rn is a smart contract hosting platform that offers an innovative solution to interoperable smart contract execution with fail-safe mechanisms built in, meaning successful multi-chain execution can always be guaranteed. Smart contracts stored in the t3rn registry can be used by anyone, while the developers that contribute smart contracts to the open-source repository can choose to get remunerated anytime their code is executed. This offers a new vision of open-source development, one that fairly rewards developers.
‍
t3rn presents a natural and inevitable evolution of blockchain technology and open-source software, one that is tailored to facilitate collaboration and built to benefit all participants.

Features of t3rn

Interoperable

Connect to the most widely adopted blockchains in the world through our unique Gateway solution

Connect to the most widely adopted blockchains in the world through our unique Gateway solution

The protocol provides uniformed standards of integrating new smart contract and transaction-based blockchains using unique Gateways.

Fail-Safe

A transaction can be reverted if it fails at any point, therefore guaranteeing successful execution

A transaction can be reverted if it fails at any point, therefore guaranteeing successful execution

Execution changes are escrowed, so that they can be reverted if they fail. Code is re-executed on the Circuit and results are compared, to ensure success.

Composable

Use any smart contract stored in our decentralised registry and get paid when people use your code

Smart contract code is separated from data and execution is standardised, which makes designing new smart contract systems easier than ever.

What does t3rn offer?

Circuit & Gateways for Blockchain projects

Plugin interoperability Circuit allows you to open up your decentralised services to a wider blockchain ecosystem.
Execute with confidence as t3rn guarantees successful multi-chain execution.
Become accessible to a rich pool of composable smart contracts and assets, including: ETH, DOT, KSM and more.

On-chain contract repository for developers

Write your smart contracts in familiar languages like !ink, Solidity, WebAssembly or anything WASM compiled.
Use the smart contracts stored in our registry or get paid when developers use your smart contracts.
Smart contracts can be uploaded as they are, no rewriting required.

Open execution platform powered by TRN

Collect fees and rewards by becoming a collator, validator or relayer.
Earn staking rewards by providing liquidity for multi-chain execution on foreign chains.
Receive support from a dedicated Contributors fund.

What’s new?

t3rn receives a second Web3 Foundation grant

The XBI Standard was proposed after an analysis of the current status quo of implementation used in the Polkadot ecosystem, concluding that there is a clear and definitive need for easier interconnection between popular smart contracts. XBI is a high-level interface that when integrated allows for the mentioned functionalities to interact with one another.

Roadmap

Scheduled

In Development

Completed

Q1 2021

Gateway

Built with Substrate, a Gateway can be integrated to provide reversible execution of Smart Contracts using Escrow Accounts and providing necessary proofs execution, storage and transfers.

Q4 2021

Circuit

Circuit implements protocol features outlined in whitepaper and works on semi-decentralised PoA premises. This enables building solutions with t3rn, as the on-chain repository and its underlying hosting is implemented.

Q2 2022

Polkadot Parachain

Circuit works on decentralised PoS premises - community members can take active roles as validators and execution agents, t3rn will then be ready to become a Polkadot Parachain.
