Generate Address

Generate an address for deposit/withdrawal.

On Unit, protocol addresses are tied to the destination address, the recipient of the deposit or withdrawal.

• For deposits, the protocol address is a Unit-derived address on the source chain (Bitcoin, Ethereum, or Solana) assigned to a user's Hyperliquid address.

• For withdrawals, the protocol address is a Unit-derived Hyperliquid address assigned to a user's address on the destination chain.

Once a protocol address is created, all future transfers received by this address - above the minimum amount - are credited to the respective destination address. The minimum amount ensures the deposit/withdrawal is sufficiently beyond the network fees associated with the operation.

Minimum Amount

Asset	Amount
Bitcoin	0.0003 BTC
Ethereum	0.007 ETH
Solana	0.12 SOL
Pump	5500 PUMP
Fartcoin	55 FART
Bonk	1,800,000 BONK
SPX6900	32 SPX6900
Plasma	60 XPL
Ethena	120 ENA
Doublezero	150 2Z
Monad	450 MON

Transactions that previously fell below minimums but now meet the new thresholds will be automatically reprocessed. Transactions that are below the minimum amount are unable to be processed.
