# Generate Address

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         |
| Doublezero | 150 2Z         |
| Monad      | 450 MON        |
| Zcash      | 0.07 ZEC       |
| Avalanche  | 1.5 AVAX       |
| Virtual    | 25 VIRTUAL     |

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.
