Tokenized Block

Build a block — name, symbol, colour, supply — and it becomes a B-20 native token on Base with a permanent Uniswap v4 market.

What a block is

• No administrator, no minter. No account holds DEFAULT_ADMIN_ROLE or MINT_ROLE — at any point, creation included.
• Supply is final at birth. It is minted inside the creation transaction and equals the cap, so no further unit can ever exist. Not for the creator, not for us.
• The market is permanent. Liquidity is deposited to the dead address. Nobody can withdraw it, and therefore nobody can collect LP fees — which is why the LP fee is set to 0.

This page holds no key, has no backend that can move funds, and presents transactions for your wallet to sign. Every state it shows is re-read from the chain: a green result means a receipt with status 0x1 was read back, never that a transaction was merely broadcast.

What it costs

moment	cost	where it goes
create a block and open its market	0.001 ETH, once, in one signature	the fee wallet, in full
every swap afterwards	0.5 % of the swap	the fee wallet, in full

Fee wallet, and the only one: 0xa6cF99D35949c6cB911adB910078F4Ca46F0f5d4 — feeWallet() on the hook returns it.

Why 0.001 ETH, and why it changed on 2026-09-21

Opening a market used to cost 0.0003 ETH — not by choice. That was a floor inherited from an older contract, and a $1 target in ETH falls below it at current prices, so the floor applied to every launch, silently. Nobody had picked that price.

prix-du-lancement.mjs then read the 103 markets opened in one day by the busiest hook on Base: 43 distinct creators, median sent 0.001001 ETH. We were asking three times less than the market, from the only side that actually pays. The new price is that median, rounded down.

⛔ This is not a revenue forecast. It aligns our price with the market's; it brings in no creator by itself. The effect will be measured — creations before and after — and published either way.

Where the fees go if you fork this

The hook declares address public immutable feeWallet. Written once, in the constructor. No setter, no owner, no admin role of its own.

	can a fork change it	why
where the fees land	no, on our hooks	immutable feeWallet, no setter
the 0.5 % swap rate	no, on our hooks	uint24 public constant HOOK_FEE = 5_000
how much is sent at launch	yes	the hook only requires msg.value >= fraisVie, and fraisVie() reads 0.0003 ETH. The 0.001 ETH is our app's choice
all of it, by deploying its own hook	yes	nothing prevents it — DEPLOY.md has the recipe

Editing FEE_WALLET in this repository changes what the app displays. It changes nothing on chain, because the app does not route the fee — the hook does.

⛔ This section used to say a fork "cannot redirect the fees". That was an overclaim twice over, and it is retracted rather than softened: a fork can deploy its own hook, and even on ours it can send the on-chain minimum instead of what we ask — 70 % less. Measured on 2026-09-21 by calling fraisVie(). test-frais-vont-au-wallet.mjs now fails if this page claims otherwise.

node test-frais-vont-au-wallet.mjs   # reads feeWallet() on 4 deployed hooks + checks the source
node preuve-frais-arrivent.mjs       # simulates a stranger opening a market, traces every transfer

The second one reports the path hop by hop rather than trusting a green status:

inconnu → hook : 1000000000000000 wei = 0.001000000 ETH
hook → a6cf    : 1000000000000000 wei = 0.001000000 ETH
rien ne reste au hook : ✅ oui

DEPLOY.md explains how to make the fees go to you instead. We would rather write that down than have you discover it.

What the chain says

Read on 2026-09-21. Every figure below is reproducible with the scripts in this repository.

The hook, read on chain

call	value
HOOK_FEE()	5000 / 1e6 = 0.5 %
feeWallet()	0xa6cF…f5d4
fee split	100 % to the fee wallet
currencies a block can be priced in	17 — ETH, TBLOCK, USDC, cbBTC + 13 tokenized stocks

The currency list lives in a deviseAdmise mapping written only in the constructor. It cannot be extended after deployment — a constraint on us, and exactly what makes it trustworthy.

Fees collected — 14 days, 1818 log windows, zero missed

fee collections	41 (2.93 / day)
ETH reaching the fee wallet	0.002798464 ETH
paid by addresses that are not ours	32.8 %, from 5 distinct addresses

Where B-20 volume actually lives — 1 day, 100 % of blocks read

	pools	swaps	distinct addresses	swaps per address
pools with no hook	20	282	19	4.3
pools with a hook	242	25 395	35	725.6

A hook does not repel traders — hooked pools get far more swaps. But 725 swaps per address is automation, not demand. Across the whole of Base, in one day, 54 distinct addresses touched a newly-born B-20 pool at all.

For scale — same day, same method

token	distinct addresses	transfers
USDC	329 365	3 610 687
cbBTC	10 816	583 892
NVDAc	2 158	35 403
TBLOCK (ours)	0	0

What is not true yet

Published here because a page that only lists its wins is marketing, not evidence.

• Two thirds of the ETH collected came from our own wallets trading our own blocks.
• Total revenue to date is well under one cent per day. This is not a business yet.
• TBLOCK, our own token, had zero transfers in 24 hours.
• There is no bridge to a bank account. Selling a block returns USDC to a wallet, not to an IBAN.
• There is no tokenized yuan or rouble on Base. We looked; what exists has a supply of zero.
• Hooks V6, V7 and V8 sat at zero markets for days. Not from lack of demand — the app's fast Create path had the hook written as a constant. Fixed 2026-09-21, and a test now refuses a second copy of that decision.

Corrections

Every claim this file got wrong, kept next to what replaced it.

what was said	what is true
"Nothing above has been done on Base mainnet"	41 fee collections were measured over 14 days
"Real Create charges a 0.001 ETH service fee"	utiliseCreateRouter() returns false; Create went to the factory at value zero
"Create is free"	true of one call, false for anyone reading it — opening a market cost 0.0003 ETH
"B-20 tokens do get traded, at scale"	43 263 swaps looked like a crowd; the address column said 35 addresses
"main holds the retired GitHub Pages stub"	Pages reports status: built and is still serving
"a fork cannot redirect the fees"	it can, two ways: its own hook, or sending the on-chain minimum (0.0003 ETH) instead of the 0.001 our app asks

Run the instruments

Each script states, in its own header, the bound of what it can prove — and several refuse to give a verdict rather than publish a biased one.

node devises-admises.mjs          # what a deployed hook accepts as a pair currency
node ou-vit-le-volume.mjs 1       # hooked pools vs free pools, by swaps AND by addresses
node bridge-devises-liquidite.mjs # how much each admitted currency actually moves
node prix-du-lancement.mjs        # what creators pay to open a market elsewhere on Base
node reference-frais.mjs          # fees now, against a reference frozen before the V6 hook existed

for f in test-*.mjs; do node "$f"; done   # 37 files, all green on 2026-09-21

Two of these instruments were rebuilt after being caught measuring badly:

• ou-vit-le-volume.mjs first read 19 windows out of 303 and would have published a ratio built on 6 % of the period — and the windows that failed were the busiest ones, so the bias ran toward the conclusion. It now splits a window in half on failure and refuses any verdict if a single block stayed unread.
• test-texte-a-l-ecran.mjs first scanned one page while the defect it was written for sat on four.

No undated figures. No ARR, MRR or projection appears anywhere in this repository. A number that was not measured is not written down, and a measurement that went against us is printed next to one that did not.
