- Ika Mainnet enables Sui smart contracts to control native Bitcoin and Ethereum without bridges or wrapped tokens.
- dWallet introduces programmable MPC wallets that sign cross-chain transactions through zero-trust smart contracts on Sui.
Sui Network has officially welcomed a new player: Ika. The protocol’s mainnet is finally live on Sui, and it immediately offers something quite bold—cross-chain asset control, without the use of bridges, wrapped tokens, or third parties.
Ika Unlocks Native Multi-Chain Power for Sui Developers
With Ika’s technology, smart contracts on Sui can directly “hold” Bitcoin, Ethereum, and other assets on different networks, without having to actually move those coins to the new chain.
No more wrapped BTC or ETH swapping. Everything is executed through a decentralized wallet system called dWallet, which can be programmed and controlled directly from smart contracts. Even more impressive, all transactions are signed collaboratively between users and the Ika network, with no single party able to “play it alone.”
Cross-chain, but make it Sui.@ikadotxyz is now live on Sui mainnet – bringing sub-second, zero-trust interoperability to builders.
Sui smart contracts can now control assets on other chains.
No bridges. No transfers. Just pure mf squid energy. https://t.co/FRhbYvr91k— Sui 「🦑」 (@SuiNetwork) July 29, 2025
Under the hood, Ika uses a zero-trust MPC approach and a new protocol called 2PC-MPC. This is said to make the process much faster and more scalable, with latency even reaching under one second. They also already have hundreds of global node operators ready to handle the load, so it’s not just a prototype. The IKA token has comprehensive functions, from paying network fees and staking to an incentive system for validators.
Sui Network Enhances Security and Usability With Key Integrations
Furthermore, CNF previously reported that in early July, Sui began supporting tBTC minting. This means Bitcoin owners can now conduct activities like borrowing and lending or trading directly through Sui’s DeFi ecosystem, without having to sell or wrap their BTC. The process relies on threshold cryptography and the native speed of Sui’s layer-1 platform.
Furthermore, at the end of May, Sui also released zkAt, an authentication feature that eliminates the need for personal user data. Users simply prove they have access rights, without revealing who they are or what rules they follow.
With an additional feature called zkAt+, all access logic can also be set privately. This means that even validators don’t know the authentication requirements. This is quite exciting for the increasingly privacy-conscious Web3 world.
And let’s not forget mid-May, when Sui officially integrated with Ledger Live. Since then, users have been able to access SUI directly from the main Ledger app, without the need for third-party plugins. This feature also includes clear signing, so users can read the contents of their transactions before signing—no longer just seeing confusing random numbers.
Now, with the arrival of Ika, the path to cross-chain interoperability is becoming clearer. Several projects like Native, Human Tech, and Rhei Finance have already begun exploring this technology integration. Just imagine: a DAO that can manage treasuries across multiple chains through a single contract on Sui. Or users who can stake Bitcoin on Sui and immediately receive returns, without moving their assets.
Meanwhile, as of press time, SUI is changing hands at about $3.80, up 35.42% over the last 30 days, driving its market cap to surpass the $13 billion mark.
