Cold Wallet

For the gateway's remaining crypto-asset holdings, LX recommends the high-security cold wallet solution FREZOR. (coming soon! Q4 2022)

Multi-signature scheme is considered a cryptographically-secure solution for high-valued assets. With stateless script, the Bitcoin blockchain supports multi-signature from the early stage. ETH's community developed a smart contract to implement the scheme, but the security of smart contracts has been always a concern for assets holders, especially after severe vulnerabilities (e.g., Terra LUNA, Phantom wallet, Parity, ect. ) were revealed in the past decade. Other coins, such as Monero, have yet to release their multi-signature features. Global Crypto Holdings provides a single-signature solution for multi-signers with a secret sharing algorithm. To solve the security problem that the entire private key is recovered in memory, the design uses banking level wys/wys (what you see/what you sign) hardware to share and recover the secret only inside the hardware key.

The co-signing process can be done in a decentralized manner, whether in-person or online. The entire signing process' security is not contingent upon how secure the USB hub or internet routing is by incorporating ad-hoc key algorithm to secure the P2P communications.
