Add ZUL to Backpack

Backpack can hold ZUL natively — no special build, no extension fork. Because the chain speaks Solana's RPC protocol, you simply point a network slot at https://rpc.zul.so and the wallet treats the L2 like any other chain. Four steps, screenshots below. The same walkthrough lives on /bridge under How to add network.

Install Backpack

Install Backpack from backpack.app and create or import a wallet. The standard release is all you need.

READS “SOL” — IS ZUL

After the switch, Backpack still labels the native balance “SOL”with Solana branding — wallet providers cannot be told a chain's native token name. The amount it shows is ZUL, the chain's native token: 1 displayed “SOL” = 1 ZUL. The explorer and bridge always display the real unit.

WHY THE MAINNET SLOT

Backpack lets you change each network's RPC endpoint, and the bridge uses devnet for the L1 side — so the mainnet slot is the free one. Pointing it at https://rpc.zul.somakes ZUL balances, transfers, and the faucet's airdrops appear natively in the wallet. Switch the RPC back any time to return the slot to Solana mainnet.
