Totalsig reduces operational costs by eliminating the need for smart contract deployment. Previously available only to large institutional players, Totalsig now makes MPC technology accessible to everyone.

Why There is Price Difference?

Unlike other solutions that rely on smart contracts, known for their complexity and high costs, TotalSig employs MPC multisigs. This newer standard, embraced by leading institutional players, significantly reduces multisig expenses and enhances the user experience.

MPC multisigs on the Optimism network are more cost-effective compared to traditional smart contract multisigs. This is because they require only one signature per transaction, bypassing the expensive deployment of a smart contract which typically incurs a large network fee.

Why Use MultiSig Wallet

Increased Security

Traditional wallets rely on a single access point, which, if breached, leaves funds vulnerable. Multisig wallets elevate security, necessitating multiple private keys for transactions. A fortified barrier, it substantially reduces the chances of unauthorized access and fund theft.

Risk Mitigation

In traditional single-key systems, if a key holder is unavailable, it can disrupt operations. Multisig addresses this risk. With multiple key holders, transactions proceed without delay, ensuring smooth business operation.

Shared Ownership

In instances where assets need collective decision-making, multisig wallets shine. By distributing control among several parties, it mandates consensus for transactions, ensuring that no single entity holds unilateral power, fostering collaboration and mutual trust.

Decentralized Organizations

Embracing the ethos of decentralization, multisig wallets cater perfectly to decentralized autonomous organizations (DAOs). With no central authority, these wallets empower collective management, ensuring that decisions and transactions echo the shared values and visions of its members.

Wallet Features

Free multisig wallets

TotalSig supports ETH, the native cryptocurrency of the Optimism network. Transactions, whether transferring ETH, OP tokens, USD stablecoins, or executing smart contracts, require ETH to cover the transaction fees.

Token Support

Our multisig wallet offers support for the ERC20 and ERC721 standards, which are the predominant token formats within the Optimism network. This ensures that any tokens adhering to these standards, whether received as part of a transaction or a smart contract execution, will seamlessly appear in your wallet.

NFT Support

TotalSig supports NFT applications, allowing you to create a treasury with your friends or business partners to easily store your Optimism NFTs.

Best fee calculator

TotalSig provides a premium fee calculator designed to ensure you pay the least possible fees. Unlike other wallets that might place a lower priority on fee optimization, leading to possible overpayments by two to three times, TotalSig prioritizes cost efficiency, especially beneficial for Optimism transactions.

About Optimism

What is Optimism?

Optimism is a layer 2 scaling solution designed to enhance the capabilities of Ethereum, the decentralized blockchain platform with smart contract functionalities. While Ethereum itself was launched in 2015 and is well-known for being the second most valuable cryptocurrency platform after Bitcoin, Optimism operates on top of Ethereum to provide faster and cheaper transactions. This is achieved through the use of Optimistic Rollups, which significantly reduce fees and improve transaction throughput without compromising the security of the Ethereum network.

Optimism ecosystem


Optimism originated from research and development efforts focused on improving Ethereum's scalability. It was developed by Optimism PBC, a public benefit corporation that includes veterans from the Ethereum community. The project builds on the groundwork laid by earlier research into scaling solutions, particularly Optimistic Rollups.


Optimism's mission is to scale Ethereum effectively while preserving its decentralized ethos. The primary aim is to make Ethereum transactions faster and more affordable for everyone, thereby facilitating broader adoption and usability of decentralized applications (DApps). This is achieved through the implementation of Optimistic Rollups, which are designed to drastically reduce gas fees and enhance transaction throughput without sacrificing the security features inherent to the Ethereum blockchain.


Optimism also does not utilize a separate native cryptocurrency but leverages Ether (ETH), the native currency of the Ethereum network, for transaction processing and network operations. Like Arbitrum, Optimism operates as a Layer 2 scaling solution by handling transactions off the Ethereum mainnet to enhance throughput and reduce costs.

Types of Optimism wallets

Choosing the perfect wallet for managing assets on Optimisminvolves exploring a range of options that cater to various user preferences across security, convenience, or a mix of both. Each type of wallet has distinct advantages tailored to different user needs and comes equipped with unique features.

Hardware wallet

Hardware wallets are widely regarded as the most secure option for storing cryptocurrency assets. These physical devices keep your private keys—the essential credentials for accessing your Optimism tokens—completely offline, thereby shielding them from online threats. To perform transactions, these devices must be physically connected to a computer or smartphone, offering a secure yet user-friendly experience, often protected by pins or passwords.

Although offering strong security, hardware wallets may be less convenient for users who frequently access their digital assets. Additionally, the cost of these devices might be prohibitive for some users.

Web wallet

Web wallets provide the highest level of convenience within the Optimism wallet ecosystem. They are accessible through browser extensions or dedicated websites and simplify the setup process to merely creating an account and setting a pin, eliminating the need for complex installations or downloads.

These wallets are ideal for users who prioritize easy access and regular transactions. However, because they are online, web wallets are more vulnerable to cyber-attacks. The centralized storage of information also makes them attractive targets for hackers. Users should be particularly cautious with custodial web wallets, where losing control over private keys could compromise security.

Desktop wallets

Desktop wallets strike a balance between accessibility and security, operating as software installed on the user's computer. They store private keys on the user's device, offering a secure means of asset storage when the device is offline—akin to hardware wallets. Nevertheless, the need for a persistent internet connection does introduce certain risks, such as susceptibility to viruses or targeted cyber-attacks.

When managed carefully—keeping the computer offline except for necessary transactions—desktop wallets provide a secure way to manage your Optimism assets. Examples like the Guarda wallet and Atomic Wallet demonstrate the potential of desktop wallets to merge security with ease of use.

Frequently Asked Questions

How do I get started?

Simply donwload the app an follow the onboarding process to create or connect your wallets.

How does MPC multisig wallet work?

MPC (Multi-Party Computation) 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.

Is it safe to use?

Our platform utilizes MPC multisig and advanced security features to protect your assets.
