Multisig multi-chain Web3 wallet

There are many multisig wallets available, each offering different features and supporting various use cases. Most multisig wallets are limited to a single protocol, which can restrict flexibility.

TotalSig stands out as the only widely available option that supports a broad range of protocols. To see how different wallets compare, check out the full article.

Download the TotalSig extension from the Chrome Web Store and follow our simple 3-step setup:

1. Create your secure account
2. Set up your multisig wallet with your preferred approval rules (like 2-of-3 signatures)
3. Invite co-signers to join your wallet

The whole process takes under 5 minutes, and you'll have enterprise-grade security for your crypto assets. Our built-in guide walks you through each step.

MPC multisig wallets utilize cryptographic protocols to enable multiple parties to collaboratively create and manage private keys without ever sharing the complete key. This allows for secure transaction signing without exposing sensitive information.

TotalSig employs bank-grade security with MPC technology, 256-bit encryption, and multi-signature protection, making it one of the most secure multisig wallets available. As a non-custodial multisig wallet, you always maintain full control.

We never have access to your private keys or funds. Your assets remain protected even if one device is compromised, since transactions require multiple approvals from independent signers. Our codebase is fully audited, and we've securely managed millions in assets without a single breach.

We support multiple blockchains including: Bitcoin, Ethereum, Tron, Solana, Litecoin, BNB Smart Chain, Tether, Dai token, NFT, Polygon, Arbitrum, Avalanche, Bitcoin Cash, Dogecoin, Optimism. See full list of supported coins and tokens.

The escrows operate using multi-signature wallets on different blockchains, enabling secure, trustless transactions between parties. When a transaction is initiated, the funds are locked in a multisig wallet controlled by both the involved parties and the platform. If both parties agree, the transfer is completed smoothly. However, if something goes wrong, such as a dispute or timeout, the platform can roll back the transaction, automatically returning the funds to the original addresses.

The platform coordinates the process to ensure that funds remain secure and can only be released with the required approvals. This mechanism functions similarly to atomic swaps, providing a secure, decentralized way to manage escrows across multiple chains.
