What is Vultisig?
Vultisig is an agent-first SDK designed to enable autonomous and secure crypto operations across dozens of blockchains including Bitcoin, Ethereum, and Solana. By utilizing the DKLS23 threshold signature (TSS) protocol, it eliminates the single point of failure inherent in traditional seed phrases. This skill allows developers using Openclaw Skills to implement self-custodial vaults that range from fully autonomous Fast Vaults to Secure Vaults requiring human co-signing.
The framework provides a robust interface for developers to build decentralized finance applications that require cross-chain mobility and high-security standards. Whether managing treasury operations or automated trading strategies, this skill ensures that private keys are never stored in a single location, significantly reducing the risk of unauthorized access.
Vultisig Use Cases
- Automated cross-chain asset rebalancing and DCA strategies using Openclaw Skills.
- Agent-to-agent payments and autonomous treasury management.
- Building self-custodial wallet interfaces for decentralized applications.
- Triggering conditional token swaps based on real-time market data.
- Implementing secure multi-device transaction approval for high-value operations.
How Vultisig Works
- Initialize the SDK with a preferred storage provider to manage vault data and session states.
- Create a Fast Vault for autonomous agent execution or a Secure Vault for flows requiring human approval.
- Retrieve chain-specific addresses for any of the 36+ supported blockchains using the vault instance.
- Execute a three-step transaction lifecycle: prepare the keysign payload, sign using MPC/TSS, and broadcast to the network.
- Monitor transaction status and refresh balances to confirm finality across various chain explorers.
Vultisig Setup
Install the Vultisig SDK via npm to begin integrating with Openclaw Skills:
npm install @vultisig/sdk
Initialize the SDK in your TypeScript project to manage your vaults:
import { Vultisig, MemoryStorage } from '@vultisig/sdk';
const sdk = new Vultisig({ storage: new MemoryStorage() });
await sdk.initialize();
