Choose one lock or a batch of up to 10 from anywhere on the map.
NULL
Most locks contain nothing.
Some don't.
A field of one million numbered locks. Pick any sealed number, open it onchain, then reveal what was hidden there. Every opening becomes permanent history.
One number. One permanent opening.
The NULL map contains exactly 1,000,000 numbered positions. Each position begins sealed. A wallet can choose any available number, reserve it onchain, then the protocol uses a future Robinhood Chain block to reveal the result. Once opened, that lock can never be chosen again.
Your transaction reserves those numbers so another wallet cannot take them.
A future block supplies the entropy. The finalizer reveals each result onchain.
Finder, lock number, result and NFT token ID stay linked to that opening forever.
Five kinds of discovery.
NULL
Nothing was hidden behind the lock. The opening still becomes permanent history on the field.
TRACE
A small clue, signal, timestamp or piece of lore left behind by NULL.
FRAGMENT
A piece of something larger. Fragments are discoveries, but they are not ERC-721 NFTs.
ARTIFACT
One of the finite NULL Artifacts. When found, the ERC-721 mints directly to the discoverer.
KEY
Golden Keys and the one-of-one NULL Key. Their purpose remains intentionally unresolved.
After finite NFT inventory is accounted for, non-NFT discoveries resolve as 75% NULL, 15% TRACE and 10% FRAGMENT.
No separate platform unlock fee.
Every transaction still pays normal Robinhood Chain gas. Your first lifetime lock is free from $NULL burn. After that, holding capacity determines how many paid locks your wallet can open.
READ ACCESS RULES āFinite things hidden in the field.
Artifact and Key outcomes are real ERC-721 collectibles. They mint directly to the wallet that discovers them, while the originating lock number remains part of the NFT's permanent identity.
Last 10 openings.
New finalized locks appear here as the indexer sees them. Click any row to inspect its permanent lock record.
Pick a number.
Leave a mark.
Select up to 10 sealed locks, inspect their state, connect a wallet and open them without leaving the map.
Select any sealed number. A lock can only be opened once.
Your first unlock is burn-free. Every 10K $NULL creates paid capacity.
2K $NULL is escrowed per paid lock and burned only after a successful reveal.
Artifact and Key NFTs mint directly to the wallet that discovers them.
