Slab Rain

The wall does the waiting for you.

Real graded slabs fall from the vault to members on a public schedule. Who's next is fixed math. Which slab is chance. Anyone can check both.

47 SLABS DELIVERED · ON-CHAIN

Real graded slabs, bought by the shop and delivered to members' own wallets. The higher the wall, the more valuable the slab.

Nothing to claim: each slab is delivered straight to the membership's own wallet and is the member's from that moment. It travels with the membership if the membership ever sells. The physical card sits insured in the Collector Crypt vault it names. Read from the chain, not a database.

7 DROPPED · QUEUE ON-CHAIN

Every activated membership holds a place in this line - it is a line, not a raffle. Weight is how often the rain calls your number: weight 12 gets slabs twice as often as weight 6. Ties go to the older membership number. Slabs land in the membership's own wallet. Nothing to claim.

How your rate is set

Your weight is where your row meets your column: stage points plus rarity points, plus the early build bonus below if you earned it. Bigger weight, more rain.

Stage + rarity★★★★★★★★★★★★★★
Fortress678910
Towered wall56789
Reinforced wall45678
First row of bricks34567
Foundation23456
Not activated00004

Five stars are the only rarity that rains without activation - the card itself carries its 4 points, even through a sale.

The early build bonus

Until Aug 17, 4:43 PM ET (block 39,132,747), nobody knew which memberships were rare - every card's star rating was drawn at once, in a single public transaction. Members who activated before that draw paid in with no idea what they held.

The bonus rides with the membership for as long as the rain falls, sized by the stage held at the draw - a Fortress built early outranks even a five-star that got lucky. Sell the membership and the bonus dies with the sale.

The dice

Who gets the next slab is fixed in advance. Which slab it is, nobody controls - including us.

1 · The recipient is already fixed

The queue above names every recipient in advance, in public.

2 · The vault is a numbered list

Every slab in the vault, sorted by token number - a fixed, on-chain ordering anyone can reproduce at any block.

3 · A future block rolls the dice

The chain stamps every block with a hash, an unpredictable serial number that does not exist until the block is mined. When a drop is due, the hash of the next block picks the slab off the vault list. Formula: slot = keccak256(blockHash ‖ dropNumber) mod vaultSize.

In plain words: the formula takes two ingredients, the block's hash and the drop number, scrambles them into one giant number, then divides by how many slabs are in the vault. The remainder points at one position on the list, and that slab is the one that falls. It works like dice nobody owns: we cannot choose the block, cannot predict its hash, and cannot reroll it, so there is no way for anyone to steer a rare slab to a friend. And because the formula is public, anyone can redo the math on any past drop and confirm the same slab comes out.

Two edge rules, so every past drop re-derives exactly: if the vault was empty when a drop came due, the dice wait and roll on the first block after the deposit that refills it. And each drop's roll always uses a block after the previous drop's delivery, so no block is ever used twice.

How hard it rains

The schedule is set once, at midnight UTC, from the vault as it stands at that moment. Start at 8 drops. Add one for every 7M $WALL activated yesterday - the busier the wall, the harder it rains. Two caps: never more than 24 a day, never faster than the vault can sustain. The smallest number wins; drops fall evenly spaced through the day.

Slabs added during the day load quietly and count at the next midnight, so the day's number never moves once published. If a setting changes, it changes here first, in public, never retroactively.

Slab Rain is a member rewards program funded by protocol activity. What falls, and how fast, depends on what the vault holds - no particular pace, card, or value is promised. The mechanics on this page are the program as it runs today, and every drop it has ever made is on-chain to check.
