Decentralized finance (DeFi) continues to grow, offering open access to financial tools like lending, trading, and yield generation. However, as the ecosystem expands across multiple blockchains, interoperability remains a key challenge. Cross-chain activity often relies on token bridges, which introduce unnecessary risks, slow down transactions, and add complexity to the user experience. Reports show that bridge-related exploits have caused over $2 billion in losses between 2021 and 2023.
Tunnl proposes a new approach.
With a mainnet launch scheduled for May 2025, Tunnl is introducing a bridgeless model that allows native asset transfers across multiple blockchains—without relying on wrapping or synthetic tokens. This system supports both EVM-compatible and non-EVM chains, aiming to streamline cross-chain activity while improving security and capital efficiency. It reflects a shift towards simpler, faster, and safer DeFi architecture.
Tunnl’s Vision: Seamless Interchain Lending and Trading
Tunnl is designed to enable native asset trading and lending between blockchains without the need for traditional bridges. Instead of depending on wrapped tokens or asset duplication, Tunnl supports direct interaction with native assets across supported networks.
The system is powered by three integrated components:
- Off-Chain Order Book: Tunnl uses an off-chain matching engine to provide high-speed trade execution. This structure enables users to experience faster transactions while reducing on-chain congestion.
- On-Chain Settlement Layer: Once orders are matched, trades are finalized on-chain to ensure transparency, auditability, and user control over assets.
- MPC-Based Vault Infrastructure: Assets are secured using multi-party computation (MPC), which distributes control among several parties. This reduces attack vectors and avoids common security flaws associated with centralized custody and bridges.
This bridgeless architecture eliminates the risks of de-pegging and minting failures that often come with synthetic assets. It also enhances composability across chains, allowing applications to interact more efficiently without additional middleware or conversion layers.
Tunnl is positioning itself as a next-generation protocol for DeFi users who want secure, seamless access to cross-chain functionality—without the usual limitations.
Technical Underpinnings: How Tunnl Achieves Bridgeless Interoperability
Tunnl sets itself apart in the DeFi space with a technical design built to eliminate reliance on traditional bridges. Instead of using token wrappers or intermediary validators, Tunnl combines three key elements to enable secure, high-speed, interchain lending and trading.
- Off-Chain Order Book for CEX-Level Performance
Tunnl uses an off-chain order book architecture that mimics the speed of centralized exchanges (CEXs). By separating the order matching process from blockchain settlement, it reduces latency and network congestion. Traders benefit from faster execution, tighter spreads, and greater efficiency—without handing over custody of their assets to a third party. - On-Chain Execution Engine for Native Settlement
Once orders are matched off-chain, Tunnl settles them natively on-chain. This means transactions are finalized directly on the respective blockchains where assets reside. The system retains DeFi’s core benefits—immutability, transparency, and decentralized control—while improving responsiveness and reliability. Native settlement ensures users avoid the risks of synthetic assets or mirrored tokens. - MPC Vaults for Secure, Decentralized Custody
Tunnl’s asset custody is powered by Multi-Party Computation (MPC) vaults. In this setup, private key control is split among multiple independent parties, ensuring no single entity can access or compromise funds. MPC drastically reduces the likelihood of hacks tied to centralized wallet providers or custodians—particularly important when dealing with assets across different chains.
Interconnected Design for Bridgeless Operation
Together, these components enable Tunnl to function as a fully bridgeless interchain protocol. Users can interact with native assets on multiple blockchains as if they were part of the same system—no need for token wrapping, locking mechanisms, or trust in third-party bridges. It’s a streamlined system that puts performance and safety at the core of cross-chain DeFi.
The May 2025 Mainnet Launch: What to Expect
Tunnl’s upcoming mainnet launch, expected in May 2025, represents a major step forward for the DeFi ecosystem. With its unique technical infrastructure, Tunnl aims to introduce a more secure, efficient, and user-friendly way to engage in interchain lending and trading.
Launch of the TUN Token
Alongside the mainnet, Tunnl will introduce its native utility token, TUN. This token will be used to pay for protocol-level operations such as transaction fees, liquidity incentives, and validator participation. It will also serve as the foundation for governance, allowing users to propose and vote on protocol changes, upgrade schedules, and feature rollouts.
Cross-Chain Compatibility from Day One
Tunnl will support both EVM-compatible chains (like Ethereum, Polygon, and Avalanche) and non-EVM chains (potentially including Solana and Cosmos zones) right from launch. This multi-chain compatibility opens the door to wider adoption and unlocks access to liquidity that is currently siloed in separate ecosystems.
Expectations for Adoption and Liquidity
By removing the need for wrapped assets, Tunnl simplifies onboarding and increases trust in cross-chain interactions. This could drive faster adoption by both DeFi users and institutional players who are typically wary of the risks associated with bridges. The team is expected to launch with a set of liquidity programs designed to bootstrap volume and activity across supported networks.
Why It Matters
Tunnl’s launch comes at a time when security, capital efficiency, and user experience are at the forefront of DeFi innovation. Its bridgeless model isn’t just a feature—it’s a statement on how decentralized protocols can evolve without repeating the mistakes of the past.
