Vultisig

Vultisig is a multi-chain crypto vault that uses Multi-Party Computation (MPC) to split your private key across multiple devices. No single device holds the full key, and there is no seed phrase to write down or lose. You approve transactions by confirming on a threshold of your devices, such as 2 out of 3.

Its core strength is eliminating the single point of failure that plagues traditional wallets. Even if one device is compromised or lost, your funds remain safe. It supports over 36 blockchains, including Bitcoin, Ethereum, Solana, and major EVM networks, all within one interface. The vault offers two modes: a Fast Vault for daily spending with lower approval thresholds, and a Secure Vault for maximum protection with stricter signing requirements.

The main pain point it solves is the trade-off between security and convenience. Traditional wallets force you to choose between easy-to-use but vulnerable hot wallets, or secure but clunky hardware wallets. Vultisig removes that choice by making multi-device approval as simple as a phone notification, while keeping the security of threshold signatures.

Over the past six months (March to September 2026), Vultisig has shipped several major updates. It launched a Plugin Store that enables third-party integrations, and released an SDK on npm that lets developers and AI agents create and operate self-custodial wallets programmatically. The team also introduced an AI agent feature, currently in early alpha, that can handle tasks like staking, yield farming on Aave, trading on Polymarket, and setting up automated strategies. Transaction history, Tron staking, and support for additional chains were added. The platform crossed $100 million in all-time swap volume, and its native token $VULT saw a 200% price increase from February lows. Security remained clean with zero reported incidents.
