Vultisig and Its Chains: How One Wallet Covers 30+ Blockchains

By Vultisig••Updated February 25, 2026

One vault. 30+ blockchains. Bitcoin, Ethereum, Solana, Cosmos, and everything in between. No separate wallets. No juggling seed phrases. No chain restrictions.

That sounds like marketing until you understand how it works. The answer is three letters: MPC.

The Chain Problem Nobody Talks About

Crypto has a fragmentation issue.

You hold Bitcoin, some ETH, maybe Solana for the speed, a few Cosmos tokens because you like the ecosystem. Normal portfolio for 2026.

Now count your wallets. MetaMask for EVM. A Solana wallet. Something for Cosmos. Maybe a dedicated Bitcoin wallet if you care about security. Each with its own seed phrase. Each a separate attack surface.

Lose one seed phrase, lose those funds. Get phished on one wallet, those assets gone. The others survive -- but only because they're completely disconnected.

This isn't security. It's fragmentation pretending to be security.

Why Most Wallets Are Chain-Locked

Traditional wallets generate private keys tied to specific cryptographic curves. Ethereum and Bitcoin both use the secp256k1 curve -- but that's where the similarity ends. Transaction formats differ. Address derivation differs. Signing logic differs.

Solana uses Ed25519 -- a completely different curve. Cosmos chains have their own address formats. Each chain speaks a different language.

Most wallet teams pick a lane. Support EVM chains and ignore the rest. Or build for one ecosystem and go deep. The ones that try to cover everything end up as thin wrappers -- basic send/receive with no real features.

The core issue: generating and storing a separate private key per chain doesn't scale. More chains, more keys, more complexity, more risk.

How MPC Changes the Game

MPC -- Multi-Party Computation -- takes a fundamentally different approach.

Instead of storing a private key on one device, MPC distributes key shares across multiple devices. No single device ever holds the complete key. Signing requires collaboration between devices using a threshold scheme (TSS).

Here's the part that matters for chain support: the signing happens off-chain.

Vultisig's vault generates both ECDSA and EdDSA key pairs during setup. ECDSA covers Bitcoin, Ethereum, and most major chains. EdDSA covers Solana, Polkadot, and others using the Ed25519 curve.

Two key types. 30+ chains covered.

The blockchain never sees anything unusual. It receives a standard signature -- identical to what any single-key wallet produces. No special smart contracts. No chain-specific workarounds. Just native cryptography that works everywhere.

The Full Chain Roster

Vultisig currently supports 30+ blockchains across four categories:

UTXO Chains

  • Bitcoin (BTC) -- the original
  • Bitcoin Cash (BCH)
  • Litecoin (LTC)
  • Dogecoin (DOGE)
  • Dash (DASH)
  • Zcash (ZEC)

EVM Chains

  • Ethereum (ETH)
  • BNB Smart Chain (BSC)
  • Avalanche (AVAX)
  • Polygon (MATIC)
  • Optimism (OP)
  • Blast
  • ZkSync
  • Cronos (CRO)
  • Mantle

EdDSA Chains

  • Solana (SOL)
  • Polkadot (DOT)
  • Sui (SUI)
  • TON
  • Cardano (ADA)

BFT / Cosmos Ecosystem

  • Cosmos (ATOM)
  • THORChain (RUNE)
  • Maya Protocol (MAYA)
  • Osmosis (OSMO)
  • Kujira (KUJI)
  • dYdX (DYDX)
  • Terra (LUNA)
  • Noble

Plus TRON (TRX), XRP, and more being added regularly.

One vault address set. All of these chains accessible from the same place. Send Bitcoin in the morning, swap tokens on Ethereum at lunch, stake on Cosmos in the evening. Same vault, same security model, same devices.

Why This Matters Beyond Convenience

Multi-chain support isn't just about having fewer apps on your phone. It's a security model.

Fewer seed phrases, fewer attack vectors. Every separate wallet is another phrase to back up, another target to protect. Consolidating into one vault with threshold security reduces your total exposure.

Consistent security across all assets. Your Bitcoin gets the same 2-of-3 threshold protection as your Solana tokens. No weak links in the chain (pun intended). No "I only set up a basic wallet for that chain because I don't hold much there."

Cross-chain swaps without leaving the vault. Vultisig integrates THORChain and Maya Protocol for native cross-chain swaps. Bitcoin to ETH without a centralized exchange. Without bridging. Without wrapping. The multi-chain architecture makes this possible inside the same interface.

Future-proof. New chain launches? Vultisig can add support without changing the vault structure. Your existing vault works with newly added chains automatically. No migration, no new seed phrases, no starting over.

The Technical Edge: Why Competitors Struggle

Most multi-chain wallets use one of two approaches:

Approach 1: One seed phrase, many derivation paths. This is how MetaMask and Trust Wallet work. One mnemonic generates keys for multiple chains. Problem: that seed phrase is a single point of failure. Compromise it and every chain is exposed simultaneously.

Approach 2: Separate wallets under one interface. A unified UI that manages independent wallets underneath. Better UX, same fundamental key management problems.

Vultisig's MPC approach eliminates both issues. There's no seed phrase to steal -- the key never exists in complete form. The threshold requirement means compromising one device gets an attacker nothing. And the dual key generation (ECDSA + EdDSA) covers virtually every major chain's cryptographic requirements natively.

This isn't a wrapper. It's a different architecture.

Getting Started

The setup takes minutes, not hours:

  1. Download Vultisig on two or more devices (iOS, Android, Desktop)
  2. Create a vault -- Fast Vault for quick setup, Secure Vault (2-of-3 recommended) for maximum security
  3. Pair devices on local network
  4. Done. All 30+ chains ready immediately

No choosing which chains to "enable." No importing separate keys. Every supported chain is live the moment your vault exists.

The Bigger Picture

Crypto's multi-chain future is already here. Bitcoin isn't going away. Ethereum dominates DeFi. Solana handles high-throughput use cases. Cosmos chains keep shipping.

Wallet infrastructure hasn't kept up.

MPC is the bridge. Not a blockchain bridge -- a cryptographic one. The signing algorithm doesn't care what chain the transaction targets. ECDSA signs for Bitcoin the same way it signs for Ethereum. EdDSA signs for Solana the same way it signs for Polkadot.

One vault. One security model. Every chain.

That's not a feature. That's how wallets should have worked from the start.
