Worried about losing access to your private wallet?
With SmashFi’s Custody Safe, we use cutting-edge MPC (Multi-Party Computation) technology to ensure that even if you lose your key, you can still recover your wallet. An encrypted share of your key is stored securely with a trusted third party—but only you can unlock it.
Your wallet, your control—backed by advanced recovery options.
Q. What is Custody Safe?
Custody Safe is SmashFi’s non-custodial wallet solution powered by Fireblocks Embeded Wallet (EW) technology. It allows you to hold your private keys, giving you full control over your Bitcoin and eliminating risks associated with third-party custodians, such as hacks or platform failures.
Q. Are there any fees for transferring Bitcoin into Custody Safe?
Transferring Bitcoin into Custody Safe is zero-fee only when the Bitcoin comes from your SmashFi account. SmashFi offers a limited number of zero-fee transfers when you acquire Bitcoin through key features like Auto-buy, Boost Funds, or Swap. As long as you’re using these SmashFi features to grow or DCA your Bitcoin, you can enjoy cost-free self-custodying with Custody Safe. However, the number of free transfer attempts will be limited within a specific period, such as weekly or monthly. Additionally, transfers from external wallets may incur fees.
Q. How does Custody Safe ensure security for my Bitcoin?
Custody Safe uses a 2-of-2 multi-party computation (MPC) signature scheme to secure your Bitcoin. This method splits your private key into two shares—one kept securely on your device and the other on Fireblocks’ secure servers. This dual-signature method enhances security and reduces the risk of a single point of failure.
Q. Why should I use Custody Safe instead of keeping Bitcoin on an exchange?
When storing Bitcoin on an exchange, you don’t hold the private keys, which means your assets are at risk if the exchange experiences problems. Custody Safe ensures that only you control your private keys, eliminating risks like exchange freezes or hacks. With Custody Safe, you have full ownership of your Bitcoin.
Q. Do I need to store a seed phrase with Custody Safe?
No, Custody Safe removes the need for traditional seed phrases. Instead, you will create a simple passphrase for wallet recovery, which you can store securely in services like Google Drive or iCloud. This simplifies the process of securing your wallet and makes recovery straightforward.
Q. What happens if I lose access to my Custody Safe wallet?
If you lose access to your Custody Safe wallet, you can easily recover it thanks to the robust backup and recovery mechanism integrated with Fireblocks’ MPC technology. When setting up Custody Safe, a key share (Key Share #2) is generated and securely stored on Fireblocks’ servers, while another key share is held by you.
To ensure that even if your device is lost or damaged, you can recover your wallet, a backup process is initiated. During this process, an encryption key is generated and used to encrypt the key share. You can back up this encryption key by storing it on cloud services like iCloud or Google Drive, or downloading it as a file. In the event of recovery, the encrypted key share is fetched from Fireblocks’ servers, and if you provide the correct encryption key, you can successfully regain access to your Bitcoin.
This advanced backup solution ensures that you never lose access to your Bitcoin while maintaining full control over your private keys, without the complexities of traditional seed phrases.
Q. Can I access Custody Safe across multiple devices?
Yes, Custody Safe supports access from multiple devices. You can manage your Bitcoin seamlessly across different platforms, whether on web or mobile, providing you with a consistent experience no matter where you are.
Q. What makes Custody Safe different from other wallet solutions?
Custody Safe offers a unique combination of security and simplicity. It removes the need for complex seed phrases, ensures zero-fee transfers for Bitcoin acquired through SmashFi features, and provides enhanced security through advanced cryptographic methods like MPC, giving you full control without third-party custodians.
Q. Can I still withdraw my Bitcoin from Custody Safe?
Yes, you can withdraw your Bitcoin from Custody Safe to any external wallet at any time. Custody Safe is designed to give you full control and flexibility, allowing you to move your Bitcoin whenever and wherever you need.
Q. What blockchains and assets does Custody Safe support?
Custody Safe supports multiple blockchain networks, including Bitcoin and Ethereum-based assets. You can store and manage Bitcoin, ERC-20 tokens, Ripple (XRP) and Tron (TRC-20) securely within Custody Safe.
