TL;DR:
Ika is a self-acclaimed fastest MPC network forked from Sui to solve Sui’s interoperability challenges.
Ika’s launch on Sui will bring more interoperability to the chain with assets like Bitcoin, Ethereum, Solana becoming more accessible to developers and users.
The MPC-powered network will launch its native token, IKA, on Sui which holders will use to pay for MPC signing services and network transactions.
The Fastest Parallel MPC Network
Formerly known as dWallet, Ika is a high-performance Multi-Party Computation (MPC) interoperability network forked from and launching on Sui in Q1 2025. Designed to address key challenges in blockchain interoperability, Ika offers speed, security, flexible asset control and interoperability. By acting as Sui’s interoperability layer, Ika aims to enhance cross-chain interactions and create a more connected DeFi ecosystem.
Sui has big plans and four main goals to achieve in 2025. The goals are to upgrade DeFi, boost liquidity, onboard more developers & users and finally to create more unique network use cases. From reaching the $2B+ TVL milestone to launching various projects – Aftermath's perpetual market launch, Suilend's upcoming AMM, Steamm – and institutional moves, Sui is positioned to solidify itself as a versatile, high-throughput, decentralized chain.
What’s the connection between Ika and Sui? Sui's ambitious goals for 2025 align perfectly with Ika's capabilities. In this article, we will look at Ika, how the MPC network works, why it’s a good fit with Sui, and the use cases that make Ika unique. Let’s start with an overview of the network.
Ika Network Overview
Ika was created by Omer, Yehonatan, and other leading cryptography and cybersecurity experts to redefine MPC networks. In detail, Ika disabled smart contracts, implementing 2PC-MPC (its novel multi-party computation protocol) while using Sui's Mysticeti consensus for MPC node communication. Because of the MPC process among nodes, the protocol ensures non-collusive network autonomy by always requiring user signatures. With Ika, builders can implement any logic – custody, DeFi, grants, gaming, governance – across any blockchain. Ika promises high throughput scaling to process thousands of signatures as a foundation for more applications and institutional demand. Furthermore, Ika’s MPC Zero Trust Protocol ensures the security of user assets even in worst-case scenarios.
The above features are a leap from traditional MPC networks that struggle with security, scalability, and low latency. Capable of signing transactions for any blockchain, Ika currently supports ECDSA, with support for EdDSA and Schnorr coming soon. For node and consensus, the 2PC-MPC protocol enables the participation of hundreds or thousands of signers in the signature process. Finally, no other party can generate a signature without the user while the user controls their native assets directly. No need for bridging or wrapping assets to use on the desired chain.
Core Ika Concepts
MPC – Multi-Party Computation: A field of cryptography that computes and processes communication through multiple entities without any entity sharing the secrets.
TSS – Threshold Signature Scheme: Authentication on the blockchain relies on public key cryptography, specifically a public/private key pair. ECDSA is the most widely used signature algorithm in blockchain systems.
DKG - Distributed Key Generation: TSS protocols generate verifiable signatures for any public key/address. For an address to be used by a group, and none knows the PK, the group’s key is generated with DKG.
Dynamic Decentralized Wallets (dWallets): Dubbed “building blocks designed for multi-chain interoperability”, dWallets are programmable and transferable signing mechanisms linked to an address on multiple blockchains that can sign transactions to each of them. Projects can build upon a dWallet and offer programmable access to any other blockchain. Builders can define and enforce the logic of each dWallet across any blockchain without the cross-chain risks. With dWallets, Ika offers a plethora of use cases, from decentralized custody to multi-chain DAOs to native interoperable DeFi with multi-chain lending, order books and many more.
Why Ika and Sui are a good fit
According to Omer Sadika, Co-Founder of Ika, "Sui is the fastest execution venue for cross-chain programmable BTC, DeFi, decentralized custody, Chain Abstraction, and AI agent guardrails."
Ika boldly claims it'll make "every chain a Sui chain" with fast, unparalleled interoperability. Imagine infinite block space. The more block space provided, the more utility users can access while more are onboarded. Sui uses Move language, a secure way to write contracts between APIs while supporting any network key signature. Add Ika, which will make Sui the base chain for every chain in the market. Without bridging, you can transfer and control your assets on Ethereum, Solana, Aptos, Unichain, or any chain you choose. For example, you can trade your memecoins on Deepbook and other Sui DEX without worrying about outages, priority fees or MEV-bots. You get to trade Bitcoin directly on an order book at a large scale - something that couldn't be done before.
Ika's integration with Sui goes beyond enhancing existing infrastructure. Its integration into Sui is no coincidence – Sui's robust architecture combined with Ika's secure MPC technology will create new paradigms in blockchain security, finance, and asset management. From programmable assets to AI oversight, Ika provides the necessary tools to build applications that are not only powerful but also secure and user-friendly.
Ika Use Cases on Sui
Chain Abstraction: Control any account on any chain from a Sui smart contract.
Wallets: Decentralized, ultra-fast MPC enabling advanced wallet features like account recovery and spending limits.
DeFi: Ika’s sub-second speed and scalability enable instant and secure multi-chain DeFi, including atomic swaps, lending, etc.
Bitcoin: Ika unlocks new possibilities for Bitcoin on Sui.
AI: Ika enables secure MPC guardrails to Sui AI apps, ensuring AI agents won’t have full unchecked power and safeguarding users’ assets.
Staking: Achieve fast and secure staking across multiple networks, allowing users to stake any asset to secure any protocol.
How does Ika Network compare to bridges?
Ika is different and more powerful than current bridges because it's an interoperability system relying on 2PC-MPC protocol and dWallets. Current interoperability solutions such as bridges, centralized custodians and MPC systems fail to meet the rigorous requirements of a truly decentralized system: no single points of failure, low latency, high-throughput operations and scalability without compromised security. A zero-trust architecture is needed to stop relying on intermediaries to fix these bottlenecks. This architecture or protocol should also be capable of low-latency and high-throughput operations and scaling to accommodate more users in the network.
Ika's core concepts, multi-party computation, threshold signature schemes, distributed key generation, dWallets and Zero Trust Protocol create the right conditions to achieve the above.
Concluding Words
The Ika mainnet launch is scheduled for Q1 2025. Their solution is expected to multiply SUI's liquidity with seamless cross-chain interactions, attracting more capital and stabilizing the general market. By leveraging Sui's infrastructure, Ika positions itself as the go-to solution for developers and is taking a crucial step toward a more connected and decentralized blockchain ecosystem, pushing the boundaries of what's possible.
Meanwhile, apart from Ika's cross-chain MPC network, there are other liquidity catalysts Sui is focused on, like Steamm AMM, Babylon/Lombard's BTCfi liquidity, and Phantom/Backpack Sui integrations. Upgrades like Mysticeti v2 and SIP-45 are on the horizon as well. Mysticeti v2 refines Sui's transaction model to bring faster confirmations for DeFi, gaming, and other resource-intensive applications. While SIP-45 addresses transaction fees during peak network activity, advocating for higher gas price limits and paying extra to process transactions faster. Both upgrades address the bottlenecks increased network activities bring and potentially eliminate congestion. All these developments point towards Sui's bold and broad ambition of onboarding more users and adopting newer, beneficial use cases.
