Ika

Ika is a decentralized signing network for builders creating protocols in which smart contracts control assets and accounts across blockchains. Its programmable dWallets use 2PC-MPC threshold signing and native chain signatures rather than bridges or wrapped assets.

Practical overview

When it fits

Consider Ika when building a protocol that needs smart contracts to govern cross-chain signing without relying on bridged or wrapped assets. Check the documented maturity of the relevant coordination environment before choosing a chain.

Who it is for

  • Protocol developers building on Sui who need smart-contract-governed signing across chains.
  • Solana builders exploring Ika's pre-alpha coordination.
  • Teams developing cross-chain DeFi, custody, treasury, wallet infrastructure or agent-policy systems.

Documented uses

  • Add programmable signing for assets or accounts on another blockchain to a protocol.
  • Make a Sui smart contract govern dWallet signing through Sui coordination.
  • Explore Solana-program-controlled dWallets in the pre-alpha builder environment.
Before you choose

Requirements & limits

The repository is public and describes Ika as live in beta on Sui mainnet and pre-alpha for Solana builders. No software license is identified in the project information.

  • Sui coordination is described as beta; Solana coordination is pre-alpha for builders.
  • Each signature requires both the user and a two-thirds threshold of the Ika network.
  • The documented implementation is in Rust and uses 2PC-MPC; node communication uses Sui's Mysticeti consensus.
  • The repository recommends reading the whitepaper before building on or using the network.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Add the Ika TypeScript SDK to a project

Install the Ika SDK as a starting point for building applications with dWallets.

Before you start

  • A project that uses pnpm.

Steps

  1. Add the Ika SDK package to the project with pnpm add @ika.xyz/sdk.

  2. Use the Ika documentation to continue with application development.

Expected outcome

The Ika SDK package is added to the project; the documentation identifies it as the TypeScript SDK for building applications with dWallets.

Guide limitations

  • The documented installation step does not explain how to configure the SDK or create and run an application.
  • Ika is described as being in live beta, and the project recommends reading its whitepaper before building on or using the network.
