# 404 · SERVER ROOM 404

4,444 recovered agent records. 404 free mints, 4,040 paid in BNB or USDT. BSC mainnet, chain 56.

## Status

CONTRACT: 0x5e6c042535db3fe1a686f238621ccbef17eaa51f (BSC mainnet, deployed 2026-11-13).
BASE URI: https://404genesis.pages.dev
TREASURY: 0x30362DcbeE6d377E7f8A92e07a01627EDA8CDd1b — set at deploy, immutable.

## Eligibility — mandatory

Every mint path requires a Binance Agent ID held by the signing wallet. The contract reads the
SPACE ID Agent ID registry directly, in the same transaction:

REGISTRY         0x60B9262456dE011F7d15a54CdD8c48bAaa8B022F   (name "SPACE ID Agent ID", symbol "AI")
handle           registry.handleOf(wallet)                    bare handle, e.g. "usii"
agentTokenId     uint256(keccak256(bytes(handle)))
eligible         registry.ownerOf(agentTokenId) == wallet

A wallet with no handle, or whose handle is owned by another wallet, gets NoAgentId() from
freeMint, mint and mintWithU. Check with agentIdOf(wallet) or getMintQuote(wallet, qty) first.

## $404 airdrop for holders

Every minted unit, free or paid, is allocated $404 at token launch. The amount follows the rank
of the dossier bound to the unit:

RANK 1-44        200,000 $404 each   44 units     8,800,000
RANK 45-444       70,000 $404 each   400 units    28,000,000
RANK 445-1444     34,000 $404 each   1,000 units  34,000,000
RANK 1445-4444    16,800 $404 each   3,000 units  50,400,000

TOKEN            $404, BEP-20 on BSC
SUPPLY           404,000,000
AIRDROP POOL     121,200,000  (30.0% of supply)
CLAIM            one claim, opened at token launch (snapshot = launch block)
PER UNIT         16,800 floor, 200,000 max (average 27,273)
ALLOCATION       airdrop 30.0% · liquidity 30.0% (LP burned) · treasury 30.0% (locked 12 months)
                 · team 10.0% (12-month linear)
RANK SOURCE      dossierOf(id) -> metadata/rarity.json; not the mint order
SNAPSHOT         token launch block; allocation follows the unit, not the original minter

On-chain status: the token is NOT deployed and the NFT contract has no airdrop function. This is a
launch commitment executed off-chain at the snapshot block, not a guarantee enforced by the
collection contract. Do not represent it as claimable from 0x<contract>.

## Free mint

to       contract
value    0
data     0x5b70ea9f

One per wallet, while freeMinted < 404. value must be exactly 0.

## Paid unit, BNB lane

to       contract
value    qty * 1500000000000000
data     0xa0712d68 + qty as a 32-byte word

## Paid unit, USDT lane

1. allowance(wallet, contract) must be at least qty * priceU. If not, send
   approve(contract, qty * priceU) to the token first (selector 0x095ea7b3), wait for the receipt.
2. to       contract
   value    0
   data     0xf86dd506 + qty as a 32-byte word

mintWithU pulls the tokens with transferFrom straight to treasury and checks that the treasury
balance grew by exactly qty * priceU; fee-on-transfer tokens and empty-return failures revert
with PaymentFailed. No token ever sits in the contract.

## Rarity

Six slots: CHASSIS, FINISH, FAULT, DRIVE, BAY, TAG.
Score = exact integer product of the six trait counts of an item.
Rank = ascending score, 1 = rarest. Integers only, no floats.
4,444 units, 4,444 distinct scores, zero ties. Every rank is unambiguous.
Rarest: case #3367, odds 1 in 505,833. Most common: case #3634, odds 1 in 3,581.

Per-trait counts and shares: metadata/trait-freq.json and docs/RARITY.md
Full rank list: metadata/rarity.json
Browser payload: web/data/collection.json

Every slot sums to exactly 100.00% (largest-remainder allocation).

## Files

metadata/NNNN.json      ERC-721 metadata, attributes + Rarity Rank + exact score and odds
web/art/NNNN.svg        1024x1024 artwork, deterministic from the case number
web/data/collection.json  id, 6 trait indices, rank, score, odds for all 4,444

tokenURI(id) = baseURI + NNNN + '.json'   (baseURI must end with '/')

NNNN is the dossier drawn at mint, not the token id. Each mint mixes the parent block hash
(blockhash(block.number - 1)) with the token id, draws one dossier from the still-unminted
pool, and removes it. The draw is uniform, without replacement, and O(1): every dossier is
issued exactly once, but which token gets which dossier is unknown until the mint transaction
is included. dossierOf(id) returns the dossier number of a minted token.

## Verify

node generator/verify.mjs

Re-derives all 4,444 records from the weights, recomputes counts, ranks and
percentages, compares every file, and rewrites docs/RARITY.md. Exits 1 on any
mismatch. Last run: all checks passed.
