FAQs
Does Hot Wallet support multi-sig or mpc technology?
Hot wallets support both multi-signature (multi-sig) and multi-party computation (MPC) technology. It depends on the specific wallet implementation. These advanced security features enhance protection by requiring multiple approvals or utilising distributed key management.
Can I move funds from the hot wallet to the cold wallet?
Yes, you can transfer funds from a hot wallet to a cold wallet. This involves generating a receiving address on the cold wallet and initiating a transfer from the hot wallet to that address. It’s crucial to ensure that you input the correct address to avoid any loss of funds during the transfer process.
Which HSM devices are supported by Liminal?
Liminal provides compatibility with popular HSM devices used for secure key management, such as devices from brands like Ledger, Trezor, or other renowned, industry-standard HSM solutions.
Can I enforce custom policies in the cold wallet?
Yes, you can create and implement custom policies in your cold wallet to move assets to different cold wallet or transfer to hot wallet. We allow multiple customisation options, such as setting transaction limits or whitelisting specific addresses.
