NULL

ONCHAIN DISCOVERY GAME Ā· ROBINHOOD CHAIN

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.

WHAT IS A LOCK?

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.

01SELECT

Choose one lock or a batch of up to 10 from anywhere on the map.

02RESERVE

Your transaction reserves those numbers so another wallet cannot take them.

03REVEAL

A future block supplies the entropy. The finalizer reveals each result onchain.

04RECORD

Finder, lock number, result and NFT token ID stay linked to that opening forever.

WHAT CAN BE INSIDE?

Five kinds of discovery.

01MOST COMMON
āˆ…

NULL

Nothing was hidden behind the lock. The opening still becomes permanent history on the field.

02NON-NFT
⌁

TRACE

A small clue, signal, timestamp or piece of lore left behind by NULL.

03NON-NFT
ā—«

FRAGMENT

A piece of something larger. Fragments are discoveries, but they are not ERC-721 NFTs.

04FINITE NFT
ā—†

ARTIFACT

One of the finite NULL Artifacts. When found, the ERC-721 mints directly to the discoverer.

05RAREST NFT
⌘

KEY

Golden Keys and the one-of-one NULL Key. Their purpose remains intentionally unresolved.

NON-NFT RESULTS

After finite NFT inventory is accounted for, non-NFT discoveries resolve as 75% NULL, 15% TRACE and 10% FRAGMENT.

UNLOCK COST

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.

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.
