t3rn Joins the Substrate Builders Program

t3rn is thrilled to announce that we are now part of the Substrate Builders Program.

This is an incredible step for the t3rn project as it gives us access to the best possible tech support and assistance in developing t3rn into a pivotal part of the Polkadot ecosystem.

What is the Substrate Builders Program?

‍The Substrate Builders Program is a Parity initiative to support the most exciting projects developing on Substrate.

In order to become a part of the Substrate Builders Program a project must present a minimum viable product or proof of concept built on Substrate, ideas without well-developed substance behind them are not the programs prerogative. A further requirement is an accountable roadmap for delivering a functioning product while on the program. t3rn was able to meet all of these expectations thanks to the support provided through Web3 Foundation grants, that allowed us to initially develop our proof of concept.

The Substrate Builders Program provides all of the support that an ambitious project needs to fulfil its potential. Upon joining the program, t3rn will be provided guidance from dedicated program managers to help in four key aspects:

Technical support
Business development support
Marketing support
Funding support

The t3rn team will work directly with Substrate engineers and technical support team to build on the proof of concept that t3rn provided to the Web3 Foundation. Once the milestones are delivered, as per the roadmap provided by t3rn, the program will be able to provide media exposure, and connect t3rn with the over 70 projects who are already building on Substrate.

This will be invaluable in helping t3rn hone meaningful partnerships with projects who can genuinely benefit from utilising our offering while providing true, tangible value to the t3rn ecosystem and all of its participants.

The program will also be pivotal in gaining organic traction and awareness that will propel t3rn to fulfilling its full potential in bringing composable interoperability to Polkadot and the wider blockchain space.

We are excited to roll out t3rn 2.0, a ground-up redesign of t3rn’s cross-chain execution and bridging stack that replaces trust-based coordination with a cryptographically verifiable, trustless execution model. Powered by the new LiquidityWellCompact architecture, which unifies order management, escrow, and liquidity into a single gas-optimized contract, t3rn 2.0 makes cross-chain transactions significantly cheaper, faster, and more reliable. With automated retries, stronger liquidity incentives, and backward-compatible, composable APIs, t3rn 2.0 moves cross-chain execution closer to being a simple, predictable infrastructure primitive rather than a fragile special case.

We’re happy to announce Lucky Bunny, our NFT PFP drop celebrating community, interoperability, and a bit of luck in the t3rn ecosystem. Inspired by the Lucky Cat and t3rn’s bunny mascot, Lucky Bunnies symbolize curiosity, movement, and connection across chains. Minted on Rari Chain, this drop is a thank-you to the t3rn community, offering simple perks like future allowlists, raffles, and early access. With an accessible mint and proceeds supporting TRN buybacks, Lucky Bunny is about being part of the story — where culture and infrastructure grow together.

As multichain activity becomes a core part of Web3, simple asset transfers via bridges are no longer enough to support increasingly complex cross-chain workflows. While bridges effectively move assets between chains, they stop short of coordinating multi-step actions, leaving users exposed to partial executions, higher costs, and manual failure handling. t3rn addresses this gap by with cross-chain execution: an outcome-driven, atomic approach where all actions across multiple chains either complete together or fully revert. Rather than managing individual transactions, users define the desired result, and the protocol guarantees execution without leaving funds in unintended states. By operating above bridges and messaging protocols, t3rn provides execution-level interoperability, enabling safer, more reliable multichain applications as blockchain ecosystems continue to fragment and scale.
