# TotalSig

> Multisig multi-chain Web3 wallet

TotalSig is a multi-signature crypto wallet built on MPC technology. It lets individuals, teams, and businesses share control of assets across multiple blockchains and require several approvals for each transaction.

TotalSig is a multi-signature, self-custody wallet that works across multiple blockchains from one browser extension account. Wallet owners set how many co-signers must approve a transaction, so no single key can move funds. It serves teams, businesses, and individuals who want shared control of crypto assets.

The wallet is built on multi-party computation, which gives one interface to blockchains with very different multisig mechanisms and keeps transaction costs low compared with smart-contract-based multisig. One account holds coins, tokens, and NFTs, and users can create several wallets for different purposes. Web3 support lets wallets connect to decentralized applications and interact with smart contracts.

Premium and corporate plans add features for larger groups of signers. TotalSig is used by crypto teams, exchanges, and companies that need approval workflows for treasury and payments, and by individuals who want an extra layer of protection.
