Terms of Use for Smart Wallets

1. About This Service

‍Tatum Smart Wallets is a non-custodial digital wallet product offered by Tatum s.r.o. ("Tatum", "we", "us") as part of the Tatum platform. These Terms of Service ("Terms") govern your use of the Smart Wallets product specifically. By activating a wallet or using the Service in any way, you agree to these Terms in full. If you do not agree, you must not use the Service.

‍2. How This Product Works

‍Tatum Smart Wallets is built on wallet infrastructure provided by a regulated third-party technology partner. When you use a Tatum Smart Wallet, the cryptographic operations including key generation, storage, and transaction signing are handled by that partner's systems. Tatum provides the product interface, integration layer, and customer support.Read more about underlying security measures behind this product here.

‍3. What MPC Wallet Technology Means

‍Your Smart Wallet uses Multi-Party Computation ("MPC") technology, a cryptographic method designed to improve the security of digital asset wallets. Rather than a single private key stored in one place, your wallet's key is split into cryptographic shares distributed across your device and our infrastructure partner's secure servers. No individual share is a complete key, which means neither Tatum nor our infrastructure partner can access your wallet independently. There is no seed phrase. Recovery is handled through backup methods such as Google Drive, iCloud, or passkeys, and all transaction signing requires cooperation between your device and our partner's infrastructure. Only you can initiate transactions from your wallet. This architecture significantly reduces single points of failure, but it does not eliminate all risk.

‍4. Your Wallet, Your Responsibility

‍Neither Tatum nor our infrastructure partner holds, controls, or has access to your private keys or funds at any time. We cannot reverse, recover, or modify any transaction once it has been signed and broadcast to the blockchain. You are solely responsible for securing your device and the backup credentials linked to your wallet recovery method, such as the Google or iCloud account you designate. If you lose access to both your device key share and your backup, your wallet cannot be recovered and your funds will be permanently inaccessible. You are responsible for verifying all transaction details before confirming, as blockchain transactions are final and irreversible.

‍5. Loss of Funds and Limitation of Liability

‍Digital assets held in a non-custodial wallet carry inherent risks that every user should understand before using this Service. Loss of funds can occur in a number of circumstances, and in all such cases neither Tatum nor our infrastructure partner bears responsibility for that loss.The most common causes of permanent fund loss are losing access to your device without having completed a wallet backup, losing access to the backup recovery method you designated during setup such as your Google or iCloud account, sharing your backup credentials with a third party who then gains access to your wallet, or sending digital assets to an incorrect wallet address. Blockchain transactions cannot be reversed under any circumstances and no party has the technical ability to recover funds once a transaction has been broadcast to the network.To the maximum extent permitted by applicable law, Tatum is not liable for loss of funds resulting from lost or compromised backup credentials, a compromised device, failures or security incidents within our infrastructure partner's systems, transactions made in error, changes in the market value of digital assets, or any regulatory, legal, or tax consequences arising from your use of digital assets. Tatum is not a bank, custodian, broker, or financial advisor. Nothing in this product or any communication from Tatum constitutes financial, investment, legal, or tax advice. You should seek independent professional advice where appropriate.
