Solana (SOL), Tezos (XTZ), Stellar (XLM) and MultiversX (EGLD) derive addresses from the private key, as opposed to other coins that use your public key to create new addresses.
As a consequence, you can only create new addresses for SOL, XTZ, XLM, EGLD and all ESDT tokens (= on the EGLD network) on the ZERO. You can’t create them on LIQUID, as your private key never leaves the ZERO.
After syncing LIQUID with ZERO, the new addresses will be available in LIQUID too.
