KA was formerly known as "dWallet Network" and will launch a parallel MPC (Multi-Party Computation) network based on Sui. With the slogan "We make all chains Sui chains," IKA still addresses the issue of cross-chain interoperability of assets.

Conventional cross-chain asset transfers typically rely on bridging protocols and wrapped assets (such as wrapping BTC into ERC-20 tokens for use on Ethereum, or bringing USDC onto Solana). However, this method has fundamental flaws:

Non-native asset risk: Users only hold wrapped tokens, not real BTC or ETH;

Bridge security risks: If the bridging protocol is attacked (such as the $624 million theft from the Ronin Bridge in 2022), user assets may be completely lost;

Anchor Crisis: Wrapped tokens may lose price peg due to liquidity issues.
Applications built on IKA as the underlying protocol can avoid the inconveniences of cross-chain assets. Taking the use case of BTC cross-chain lending as an example, the process is as follows:

Create a dWallet (which will be detailed later) and bind a BTC address;

Initiate a loan request through a smart contract;

BTC locked on the Bitcoin chain (not wrapped);

Receive loan funds on the Ethereum chain in real time.

This has further achieved:

Asset Lock: BTC cannot be moved before repayment;

Automatic liquidation: If the BTC price plummets or the loan is overdue, the collateral will be automatically liquidated.

Zero Trust Assurance: Fully secured by the 2PC-MPC protocol, no one can misappropriate assets.

IKA is the underlying interoperability protocol for B2B. The above use case is just one of the applications that can be built on it. In fact, there are already more than a dozen projects (mostly from the Sui ecosystem or have established partnerships with Sui) connected to IKA, covering four core scenarios:

DeFi interoperability

Full Sail and other protocols achieve real-time liquidity injection for BTC/ETH on the Sui chain DEX through IKA, allowing users to directly participate in staking and lending with native BTC.

Institutional-grade custody

Aeon provides institutional investors with a multi-signature asset management solution based on IKA, with private key shards distributed across hundreds of nodes globally, balancing the issue of "self-custody vs compliance";

Chain Abstract Experience

Covault utilizes IKA+zkLogin to create a "seamless cross-chain" wallet, allowing users to directly operate Solana NFTs and Ethereum DeFi on the Sui chain.

Bitcoin Financialization

The Native protocol is developed on IKA to create a BTC options market, realizing programmable yield strategies for native Bitcoin for the first time.

Another area worth noting is the fusion of AI and Web3 scenarios: Teams like Atoma use IKA to set up trading firewalls for AI agents, ensuring that automated investment decisions cannot exceed their authority to transfer assets, providing a secure foundation for the AI+DeFi market.

So how does IKA achieve cross-chain asset interoperability and attract these applications to connect?

Technical Principles

IKA's core technology can be summarized into two main modules - dWallet (decentralized wallet) and 2PC-MPC (two-party computation - multi-party secure computation) protocol, allowing users to directly use native assets like BTC, ETH, etc., to participate in a multi-chain ecosystem without relying on wrapped tokens.

dWallet: Cross-chain "All-in-one" Wallet

dWallets are like the "universal key" in the cross-chain world: users can manage multi-chain assets through a single interface. The private key of each dWallet is split into multiple "key shares" and distributed across different nodes in the network. When a user initiates a cross-chain transaction, the network nodes and the user each participate in the signing operation with their respective key shares, without ever reconstructing the complete private key. This means that there is never a risk of single-point private key leakage under any circumstances.
