Self-custodial · 32+ chain families
Two shares. One signature. No seed phrase.
M5wallet is a self-custodial multichain wallet built on 2-of-2 threshold signatures. Two parties each hold a key share and co-sign together, so your private key is never assembled in one place — not on your phone, not on a server, not anywhere.

M5 Vault
The key is never assembled, so there is nothing to steal in one piece
A conventional wallet derives one private key from a seed phrase. That key exists in full, on a device, and anyone who obtains it or the phrase behind it controls the funds. M5 Vault removes that single object entirely.
Two independent shares
Key generation is a distributed ceremony. Each party ends up with a share that is mathematically useless on its own — no share can derive the key, and no share can produce a valid signature alone.
Co-signing, not key exchange
To sign, the two parties exchange protocol messages derived from their shares over an encrypted channel. The shares themselves never move, and the full key is never reconstructed at any point in the protocol.
Ordinary signatures on chain
The result is a standard ECDSA or Schnorr signature. Networks, explorers and contracts see a normal transaction — there is no special contract to deploy and no chain-specific support required.
Multichain
32 chain families, one balance
Bitcoin and every EVM network, plus Solana, Tron, TON, XRP, Cardano, Polkadot, Cosmos and more — held in one vault and shown in a single portfolio.
Built in
A wallet you do not have to leave
Swaps, perpetuals, markets, dApps and staking are part of the product, not a set of external sites you are handed off to.
M5 Vault — 2-of-2 threshold signatures
There is no seed phrase that can be photographed, phished or found in a drawer, and no single device whose compromise hands over your funds.
Keyless onboarding
You can be holding assets in under a minute, and you still hold them — this is self-custody, not an account with a custodian.
Unified portfolio
One screen answers what you have, wherever it lives.
Cross-chain swap
Moving between chains does not mean trusting a bridge site you found in search results.
Perpetual futures
Positions and spot balances sit side by side instead of on separate platforms.
dApp browser with WalletConnect
Connecting to an application does not require pasting your address into an unfamiliar page.
Everywhere
Same vault, every surface
Your vault is not copied between devices. Each platform is a client of the same 2-of-2 vault, so adding a device never means duplicating key material.
