t3rn and Composable Finance Partnership

t3rn is thrilled to announce the first showcase of our technology in action, in partnership with Composable Finance, the cross-chain DeFi platform.

The partnership will research connecting the t3rn Volatile Virtual Machine (VVM) to expand the utility of the Composable Finance cross-chain virtual machine (XCVM), expediting the computation of cross-chain smart contracts across various L1 and L2 networks, pushing the shared values of both projects, namely interoperability and composability. Both of these qualities are foundational pillars of Composable Finance and t3rn and, as such, a partnership between the projects was a natural fit.

This marks a major milestone for t3rn and is the first step in showcasing the technology that we are building.

About Composable Finance

Composable Finance is building the core infrastructure that will play a key role in empowering DeFi to deliver on its undeniable potential, offering an arsenal of tools that allow for the seamless interaction of L1 blockchains and L2 scaling solutions.

Composable’s XCVM provides an interface that enables developers to interact with different bridges, with a view to building a single access point, known as the Innovation Availability Layer (IAL), that supports cross-chain and cross-layer transactions. With this capability, an action such as borrowing an asset against collateral can be routed through an ecosystem-agnostic path, maximizing for users’ preferred outcomes and parameters. Composable Finance utilises a suite of unique tools to achieve their ambitious goals including the priorly mentioned composable XCVM, a routing layer, their parachain and Mosaic, a cross-layer liquidity solution.

Composable Finance will operate as a parachain, a chain that is connected to Polkadot’s relay chain and have recently launched their Picasso parachain on Kusama.

Goals of the partnership

t3rn and Composable Finance will support each other in their common goal to facilitate smart contracts operating across a multitude of blockchain platforms.

This is what Cosmin Grigore, the Founder & CEO of Composable Finance had to say about the partnership with t3rn.

“t3rn is an interoperable smart contracts platform. The fundamental technology they've created will change how we envision smart contracts interacting with chain runtimes.” 

The core scope of the work will revolve around utilising the t3rn protocol to enable cross-chain executions in a fail-safe manner. t3rn's composable contracts registry and the execution system will be made available and integrated within the Composable Finance in order to facilitate cross-chain reversible executions. This integration will allow users to efficiently execute cross-chain transferrals, while guaranteeing that the execution can be carried out in a fail-safe manner. Decentralised and interoperable arbitrage protocols, liquidity pools and yield farms are all examples of services that will stand to benefit from this integration.

Furthermore, projects launched on Composable Finance will also be integrated into t3rn’s composable smart contracts systems which will spark and grow an ecosystem of projects on t3rn.

Both Composable Finance and t3rn are dedicated to simplifying DeFi processes through the creation of user-friendly ecosystems and this ambitious partnership is a significant step in that direction. An in depth analysis of the Composable Finance integration and use case will be written once the integration is complete.

More to come

This is a partnership that the whole team at t3rn are very proud of but it is just the beginning of integrations of the t3rn protocol.

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.
