What is Ika Move Integration?
The Ika Move skill provides a comprehensive guide for developers to integrate the Ika dWallet 2PC-MPC protocol into Sui Move smart contracts. This allows for the creation of programmable dWallets capable of cross-chain signing, enabling Sui contracts to interact with chains like Bitcoin, Ethereum, and Solana. Using Openclaw Skills like this one ensures developers can implement high-security cryptographic patterns without managing raw private keys.
By leveraging the 2PC-MPC architecture, this skill facilitates the generation of distributed keys where no single party holds the full secret. This is essential for building decentralized treasuries, cross-chain bridges, and automated governance systems. The integration supports various curves and signature algorithms, including SECP256K1 for Bitcoin/Ethereum and ED25519 for Solana, all managed through the Openclaw Skills ecosystem.
Ika Move Integration Use Cases
- Building cross-chain DAO treasuries that manage assets on multiple blockchains via Sui governance
- Implementing programmable automated trading bots that require secure, non-custodial signing capabilities
- Creating multi-signature wallets with custom approval logic and time-delayed execution
- Migrating existing private keys into a decentralized MPC environment for enhanced security
How Ika Move Integration Works
- Initialization: Set up the DWalletCoordinator shared object to manage all protocol mutations and reads.
- Key Generation: Execute Distributed Key Generation (DKG) to create a Shared or Zero-Trust dWallet.
- Presigning: Generate and manage a pool of presign capabilities to ensure signatures can be generated immediately when needed.
- Approval: Use contract logic to issue a MessageApproval, authorizing the dWallet to sign a specific payload.
- Execution: Request the final signature using the verified presign and approval tokens to produce a valid cross-chain transaction.
Ika Move Integration Setup
To get started with this skill, update your Move.toml with the necessary dependencies:
[dependencies]
Sui = { git = "https://github.com/MystenLabs/sui.git", subdir = "crates/sui-framework/packages/sui-framework", rev = "framework/testnet" }
ika_dwallet_2pc_mpc = { git = "https://github.com/dwallet-labs/ika.git", subdir = "deployed_contracts/testnet/ika_dwallet_2pc_mpc", rev = "main" }
ika = { git = "https://github.com/dwallet-labs/ika.git", subdir = "deployed_contracts/testnet/ika", rev = "main" }
Install the TypeScript SDK to handle off-chain cryptography and transaction building:
pnpm add @ika.xyz/sdk
Ika Move Integration Data Schema & Taxonomy
The skill organizes its operations around several core capabilities and structures. These are often stored within a contract's state to manage permissions and pending operations.
| Capability | Description | Storage Strategy |
|---|---|---|
| DWalletCap | Primary authorization for a specific dWallet | Stored in main contract object |
| UnverifiedPresignCap | A pending presign request | Typically managed in a vector pool |
| SessionIdentifier | Unique ID for protocol operations | Created fresh for every transaction |
| MessageApproval | Temporary authorization for a specific message | Consumed during the signing call |
Ika Move Integration Advanced Features
- Future Signing: A two-phase signing protocol that separates the initial commitment from the final execution, ideal for governance votes.
- Key Importing: Supports importing existing private keys into the dWallet system while maintaining MPC security guarantees.
- Zero-Trust Conversion: Allows for the irreversible conversion of a user-held zero-trust wallet into a shared contract-owned wallet.
- Multi-Curve Support: Native handling for SECP256K1, SECP256R1, ED25519, and Ristretto curves within the same framework provided by Openclaw Skills.
