TOKI Officially Connects Ethereum and BNB Chain using IBC with Unified Liquidity Pools
Hello, IBC fans and DeFi enthusiasts!
We’re excited to share that with TOKI, you can now seamlessly swap assets between Ethereum and BNB Chain using IBC!
This has been made possible through IBC, light clients, and single-sided unified liquidity pools alongside a first-party front end. This marks a major milestone not only for us but for the entire IBC ecosystem.
Since 2021, the TOKI team has been deeply engaged in interoperability R&D, making significant contributions to IBC, including ibc-solidity and light clients for various blockchains. Contributions to IBC include enterprise partnerships. We have collaborated with major financial institutions, such as MUFG (Mitsubishi UFJ Financial Group), Progmat, JCB, Mizuho, and even Swift to build a cross-border stablecoin transfer platform. Learn more about our partnerships here.
In this first version, TOKI’s “β Mainnet” supports Ethereum and BNB Chain. However, we’ll expand IBC to Optimism, Base, Arbitrum, ZK-rollups, Avalanche, Polygon, Solana, and more throughout 2025. IBC will be everywhere! Let’s make “The Internet of Blockchains” a reality together!
We have also just launched the TOKI Point Program. We greatly appreciate the contributions of our community members and those in the IBC ecosystem alike. To show our appreciation, we plan to recognize specific role holders as well as IBC fans who have previously made IBC transactions! （Learn more about the TOKI Point Program here.)
We’re excited about what’s ahead in 2025, including opportunities for our early community contributors and initial users. While our supported networks are still limited, we’d love for you to join us, share our vision, and experience our service.

Vision
Our ultimate vision is to empower billions globally through groundbreaking applications built on our infrastructure. The Internet of Blockchains isn’t just a concept — it’s the future, where app-to-app and mesh interoperability becomes the standard, seamlessly connecting networks just like the Internet or today’s Cosmos ecosystem.
We are committed to building interoperability infrastructure that enables open and app-to-app connections.
The benefits of the App-to-App connections compared to the hub-and-spoke model are:
Building the foundation for this vision hasn’t been easy, but a true global standard must always be open, permissionless, censorship-resistant, and scalable. We’re creating the infrastructure that will be essential for the long term.
What’s TOKI Bridge?
We offer a first-party front end built on the core messaging and the single-sided unified liquidity pool in the middleware stack. The bridge app offers a super-easy transfer experience of native assets across blockchains and superior capital efficiency.
The TOKI Bridge has 3 unique features:
1. Security First
LCP (Light Client Proxy), which is a middleware that adopts a multi-prover security model on IBC by combining TEE and ZKP, provides another level of security without imposing heavy costs on users. (Learn more).
2. 1 Click UX and High APY
The single-sided unified liquidity pool simplifies token swaps by eliminating the need to manage wrapped tokens, enabling seamless, one-click native token swaps across different chains. It also reduces capital fragmentation, enhancing overall capital efficiency. (Learn more)
3. Revenue Maximization
The flexible composability design allows seamless integration with any DApp, enabling not just transfers but also one-click cross-chain payments, deposits, lending, and more. This drives higher transaction volume and maximizes revenue for all stakeholders. (Learn more)

How it works
The animation below describes the entire transaction flow of the TOKI Bridge.
In a nutshell, we use IBC as a messaging protocol and LCP for light client verification using the multi-provers security (TEEs and ZKPs), ensuring both security and cost efficiency. Built on this messaging layer, TOKI integrates single-sided liquidity pools, enabling seamless, one-click cross-chain swaps with improved capital efficiency. Currently, TOKI uses Intel SGX for TEE, with ZK prover support coming in 2025.
You can check more details on each component here.
Why IBC?
We use IBC as our primary messaging standard, which inherently includes a light client verification system. Unlike any other, IBC is a truly open and comprehensive interoperability protocol.
- The most comprehensive — IBC enables fully permissionless connections and supports all types of transactions, including asynchronous ones.
- No vendor lock-in — As the only open protocol free from business model constraints, token dependencies, or corporate interests, IBC offers complete flexibility — just like today’s TCP/IP.
- Proven and battle-tested — With $2.9 billion in monthly transaction volume, zero exploits, and a thriving developer community, IBC has a track record that speaks for itself.
These advantages create a powerful flywheel effect, accelerating IBC adoption across the ecosystem.
Why Multi-provers?
TOKI employs a multi-prover approach, combining TEEs and ZKPs to enhance light client verification, as there is no one-size-fits-all solution. Below are the key approaches for enabling light client verification between multiple blockchains:
- Connected chains: This approach involves implementing a light client smart contract on each connected chain. It is the most trust-minimized method but is currently infeasible on certain blockchains, particularly Ethereum.
- Middle PoS Chain (Economic Security): This method uses a PoS chain as an intermediary to verify and submit proofs. While it provides economic security, it is inefficient and unsustainable for a bridge. For example, maintaining a PoS chain with a $500 million FDV and allocating 7% of tokens to validators would result in an annual cost of approximately $35 million.
- TEE (Hardware Security): This approach implements light client logic within TEEs like Intel SGX. TEEs have never been exploited in practice, demonstrating their high level of security. They also offer cost efficiency and minimal latency. However, potential vulnerabilities remain a concern.
- ZKP (Software Security): This approach uses Zero-Knowledge Proofs (ZKPs) to implement light client logic. It is highly trust-minimized but still in its early stages, with potential bugs, higher gas costs, and latency concerns.
- Multi-sig: This approach has been compromised multiple times and is not a reliable option. It also tends to rely on full nodes.
None of these approaches alone can fully ensure both security and cost efficiency. That’s why TOKI adopts a multi-prover strategy, leveraging both TEEs and ZKPs to compensate for each method’s weaknesses. Additionally, TOKI plans to integrate economic security in the near future.
