Ika

Ika is redefining secure, decentralized computation with its advanced 2PC-MPC (Two-Party Computation – Multi-Party Computation) network — the fastest of its kind. By combining speed, scalability, decentralization, and zero-trust security, Ika introduces a powerful new blockchain primitive: the dWallet, a decentralized, programmable, and transferable signing mechanism.

dWallets: A New Blockchain Primitive

At the core of Ika’s innovation lies the dWallet, a novel concept that functions as a zero-trust, programmable, and transferable signer. Unlike traditional custody models or smart contract wallets, dWallets allow for secure, decentralized control of assets without centralized intermediaries or reliance on bridging or wrapping.

Key use cases enabled by dWallets include:

• Programmable Bitcoin: dWallets make native Bitcoin programmable via Sui smart contracts.
• Decentralized custody: Institutional-grade, zero-trust security for asset management.
• Interoperable DeFi: Direct control of assets across blockchains without bridges.
• Novel applications: dWallets enable use cases like account marketplaces or the collateralization of entire accounts — innovations not previously feasible in Web3.

Ika + Sui: Turning Sui Into Web3’s Universal Coordination Layer

Ika is purpose-built to integrate with Sui, one of the fastest-growing Layer‑1 blockchains. By embedding dWallets into Sui, Ika transforms it into a universal coordination layer for Web3, where any native asset from any chain can be controlled by a Sui smart contract.

This architecture removes the need for bridges or wrapped tokens, drastically improving both the security and user experience of cross-chain applications. Sui’s high throughput and low latency complement Ika’s MPC technology to create an ecosystem capable of handling institutional-grade and user-centric DeFi workflows with unmatched performance.

2PC-MPC: A Cryptographic Breakthrough

Ika’s underlying cryptographic engine, 2PC-MPC, introduces a paradigm shift in secure signing infrastructure:

• Threshold signatures: Supports ECDSA, EdDSA, and Schnorr signatures, ensuring broad compatibility across all major blockchains.
• Parallel execution: Signature generation can occur in parallel, scaling linearly with the number of operators and enabling thousands of signatures per second.
• Zero-trust security: Implements a dual-share signing model (user + network share), meaning a signature cannot be generated without active user involvement, even if parts of the network are compromised.
• ZK and homomorphic encryption: Eliminates traditional MPC trade-offs by using zero-knowledge proofs and advanced encryption to maximize both performance and privacy.

Unmatched Performance Metrics

Ika’s 2PC-MPC model delivers industry-leading results across critical metrics:

• Decentralization: Scales to hundreds or thousands of nodes without latency degradation.
• Latency: Achieves sub-second signature generation, the fastest among all MPC networks.
• Throughput: Parallel execution supports thousands of signatures per second, meeting institutional and consumer demand at scale.
• Security: Maintains zero-trust assumptions across a decentralized network, making it ideal for custody, asset management, and on-chain governance.

Institutional-Grade Features

Ika also supports institutional needs by allowing existing key imports, meaning businesses can retain full key backups while deploying customizable, on-chain security policies. This provides a practical bridge for traditional financial institutions to transition into decentralized custody models without compromising compliance or operational flexibility.
