Developer & Localnet
EVE Vault includes a dev mode with tools aimed at builders: pointing the wallet at a local Sui network, loading a raw private key for local testing, and a few utilities for signing test transactions and rotating keys. These are off by default and intended for development only.
Enabling dev mode
Dev mode is a toggle. Turning it on reveals the developer menu items and the localnet settings route.
Signed out — a small floating eye button in the bottom-right corner of the sign-in screen toggles dev mode.
Signed in — open the account menu and flip the Dev mode switch at the top.
When dev mode is off, the developer items are hidden and the localnet settings page redirects away.
Localnet settings
With dev mode on, open Localnet Settings from the account menu. (Selecting the localnet network without a keypair loaded also brings you here.) The page has three sections.
RPC URL
Enter your local node's URL — the default is http://127.0.0.1:9000 — and click Save URL. EVE Vault validates the URL and checks connectivity by calling the node (suix_getLatestSuiSystemState). The status line shows Connecting…, then Connected or Connection failed.
Private key
For local testing you can load a raw private key directly:
Make sure the vault is unlocked (a key can only be loaded into an unlocked vault).
Paste a key in the Private key field. It must be in
suiprivkey1...format.Click Load Key. On success you'll see Key loaded.
EVE Vault derives a keypair from the key and shows the resulting address in the SUI ADDRESS section.
Localnet development only. Never load a private key that controls real assets. This feature exists for testing against a local network — do not use it with mainnet or testnet keys.
SUI address
This shows the address derived from the loaded key, or No keypair loaded if none is set.
Developer utilities
With dev mode on, the account menu gains a few extra actions:
Sign and submit test — builds and submits an empty transaction from your address, to confirm signing works end-to-end. You'll get a Transaction submitted! toast and a link to the explorer.
Rotate eph key — rotates the ephemeral signing key (useful when debugging zkLogin session state); details are logged to the console.
Faucet test SUI — opens the current network's faucet in a new tab so you can fund your address with test SUI. Available on networks that have a faucet (e.g. devnet/testnet), not on mainnet.
Unlock expires in {m:ss} — a read-only countdown to the vault's auto-lock.
v{version} — the installed app version.
