Vanity Addresses

Custom contract address suffix. Two modes: instant claim from pre-generated "pump" pool, or server-side grind for custom suffixes up to 5 characters.

Modes

Mode	Speed	Suffix	Description
pump (default)	Instant	"pump"	Claims from pre-generated pool of keypairs. Next keypair pre-claimed after each launch.
custom	Variable	1-5 chars	Server grinds a matching keypair via GPU. 2-3 chars = fast, longer = slower (30s timeout).

Pump mode

Atomic compare-and-swap claim with 1 retry on race condition
Rate limit: 100 claims per 60 seconds per user
Secret key nulled from pool after claiming
Pre-claimed proactively and cached in memory (vanityCache)
Preview shown on launch page before launching

Custom mode

Suffix validation: 1-5 characters, base58 only
Timeout: 30 seconds. Falls back to random keypair on failure.
Proxies to local GPU grind server (GRIND_SERVER_URL)
Setting: customSuffix in user settings

Storage

Claimed keypair cached in localStorage under vanityPreview. Consumed on launch, refreshed immediately after. Mode controlled by settings.vanityMode.
