Sui is taking a giant leap toward cross-chain dominance with the launch of the Ika Mainnet, a powerful new protocol that enables native smart contract control across multiple blockchains. At the heart of this breakthrough lies a 2PC-MPC, a threshold signature cryptographic protocol many thought impossible to create, giving Sui smart contracts the power to natively control assets on other chains, no bridges, no compromises. “All your chains are belong to Sui,” says Ika’s announcement, marking a bold new chapter for the protocol.
Breaking Boundaries
With Ika, Sui is leading the charge into an era where blockchain boundaries fade away. Smart contracts on Sui can now coordinate with Bitcoin, Ethereum, Solana, and more directly, securely, and without relying on legacy bridges or wrapped tokens.
This gives developers access to completely new UX flows. For example, think about DeFi apps on Sui that get liquidity from Ethereum or game assets that transfer easily between chains. Ika’s infrastructure is the foundation for a huge amount of composability.
The Cryptographic Breakthrough
Ika (formerly dWallet Network) is different from older custody-focused MPC systems since it uses a special cryptographic protocol called 2PC-MPC. Ika’s design is different from other older systems that have issues with latency, centralization, and user control. It features sub-second latency, grows linearly with demand, and more than 100 operators support it at launch. Most importantly, it preserves cryptographic zero-trust guarantees, which implies that users never lose control of their assets. This new feature lets you make signatures across chains in real time, which makes activities across chains as easy and safe as operations on a single chain.
The IKA Token
The IKA token powers its permissionless proof-of-stake consensus, which makes it safe to create signatures. It encourages operators by charging them transaction fees, stops spam, and lets people who use the protocol make decisions about its future. IKA makes sure that the network stays scalable, safe, and truly decentralized as it grows by building an economic fortress around Ika’s cryptographic core.
What’s Next?
With the launch of Ika mainnet, Sui smart contracts can now directly control assets across all chains through the dWallet primitive, eliminating the need for legacy bridges. This opens up a world where Bitcoin can use any protocol and smart contracts can run on networks other than their own.
Sui’s vision is clear: this is the time of coordination, when dWallets, native control, and cryptographic innovation make blockchain genuinely borderless.
