A Uniswap v4 pool that runs the novel's rubric. Every trade gets a receipt: a 1% base, a charge for the power it exerts, a charge for the automation it shows. Small human trades pay the base. The powerful are seen, and pay. The machines pay the people.
Live from the chain once STEERING is launched.
A small trade pays 1% and nothing else. Nobody asks who you are or why you are here.
A wallet that takes more than 1% of the pool in a block pays 1–3% more, written on its receipt for everyone to read.
Turning a trade around inside a block costs 10% more; inside a longhour, 2%. Every surcharge is paid to the holders in ETH.
Veridia did not stay free by forbidding things. It priced them.
In Snowmoon, Vitalik Buterin's novel, the free republic of Veridia keeps an institution beside its parliament: the Order of Steering. It writes rubrics. Every activity gets a tier of tax, from nothing up to two-fifths, set by what it costs everyone else.
Across the sea, the Arctic Empire grows the other way: one head, many bots, no consent. The book ends on the principle that outlasts the war: privacy for the weak, transparency for the powerful.
STEERING puts that principle on a market. Its rubric is written once, in public, into an immutable hook. No key can change a tier, a split or a recipient.
Computed on chain from public facts, for every swap in every shape, and written to the chain beside the trade.
| Line | Rule | Charge | Goes to |
|---|---|---|---|
| BASE | Every trade, every size, every speed. | 1% | 0.4% owner · 0.3% graph · 0.3% holders |
| POWER | A wallet's ETH in this block, summed, against the pool's virtual ETH reserve. Under 1% → nothing · 1–3% → +1% · 3–6% → +2% · above 6% → +3% | 0 – 3% | holders |
| AUTOMATION | A wallet turning its own direction around. Same block → +10% · within one longhour (720 blocks) → +2% | 0 – 10% | holders |
| CAP | Everything included. | 15% |
Base 1%. Total 1%. Nothing else is asked.
Base 1% + power 3%. Total 4%, and the 3% goes to every holder.
The way out pays base 1% + automation 10%, plus power for its size. The bot pays the people.
Snowmoon is Vitalik Buterin's 2026 novel, released under the GPL v3 at vitalik.eth.limo/snowmoon. STEERING is a fan project, not affiliated with him. Scenes are paraphrased.
Beside Veridia's parliament sits an anonymous order that writes rubrics: a tier of tax for every activity, set by what it costs everyone else. STEERING is that rubric, on one market.
The book's tiers rise in steps by how much an actor hides and how much harm it does. STEERING's power and automation lines rise in steps too: 1, 2, 3 and 10%.
A taxi ride in Freetown comes with a receipt that lists every charge. Every STEERING trade gets one too, written to the chain.
The enemy is automation without consent. Here, the fastest turnarounds pay the most, and what they pay goes to the holders.
Under threat, Veridia survives by being many and small. STEERING's holders earn ETH on at most one million tokens a wallet.
Veridia funds public goods down a graph of weighted causes. STEERING sends 0.3% of every trade down a fixed graph, named at birth.
Dzego's decimal day has ten longhours. One longhour is 8,640 seconds: exactly 720 Ethereum blocks. That is the automation window.
The book's closing principle, and STEERING's whole design: the small pay the base and are asked nothing; the large are written down and pay.

STEERING is a token with one Uniswap v4 pool, ETH/STEERING, and a hook that prices every trade by a rubric taken from the Order of Steering in Vitalik Buterin's novel Snowmoon. The rubric has three lines (base, power and automation), and every trade gets a receipt listing them.
The fees are paid in ETH: a fixed 0.4% to the owner, a fixed 0.3% to a graph of public goods, and everything else to the people holding STEERING.
STEERING trades in its pool from the Uniswap app, any aggregator or any router. Nothing special is needed: no hook data, no allow-list. Every swap pays its rubric on its ETH side, in all four shapes: buying or selling, with the amount in or the amount out fixed.
The board shows what your trade would pay before you make it.
Each trade emits Receipt(wallet, buy, eth, base, power, automation, fee). The three lines are in millionths of the ETH side (10,000 is 1%); fee is what was paid, in wei. The board lists the latest receipts as they land.
Holding STEERING earns ETH from the moment you hold it. Call claim(to) on the token, or press Claim on the board. You keep what you earned when you sell; you earn nothing from before you bought.
The graph's ETH waits in the hook, node by node. Anyone may call fund(i) to send node i what it is owed. The board has a button for each.
1% of the ETH side of every trade. It is the only line most trades ever pay.
The pool's virtual ETH reserve is its in-range liquidity divided by the square root of its price: the ETH it would take to buy every token on the current curve. Power compares a wallet's ETH in this block, summed over all its trades in the block, with that reserve:
Summing across the block means slicing a trade inside a block doesn't hide it. The reserve is read as the trade finds it.
A wallet that trades in the opposite direction to its own last trade pays:
Trading in the same direction is never automation, and a turnaround after a longhour is just a trade.
The rubric reads the transaction's signer (tx.origin), so it works through any router. It prices the trade and decides nothing else: no permission, no list. A wallet can be split, and a split wallet pays the base like everyone; its parts still pay for the power each one takes in a block.
Of every trade's ETH side: 0.4% to the owner, 0.3% to the graph, and the rest of the fee to the holders. That is 0.3% of the base, plus every power and automation charge. The owner's part never grows with a surcharge.
The holders' part is shared at once, through an accumulator in the token, among every wallet in proportion to its STEERING, counted up to 1,000,000 STEERING a wallet. A whale earns like a person. Splitting a whale into many wallets only earns what its tokens would have earned uncapped; it never earns more. The pool, the hook and the burn address never earn.
Up to eight recipients, each with a weight out of 10,000 and a label, were written into the hook when it was deployed and can never change. Each trade's 0.3% is split among them by weight. The Contracts tab lists them.
The whole supply went into the pool in one position, one-sided, below the opening price, with no ETH in. The Uniswap app minted that position's NFT to the owner. The Contracts tab shows who holds it, read live from Uniswap's PositionManager.

WrongPool · NotOwner a pool the hook refuses to bind
NotToken only the token pays holdersNo. The rubric is the same from the first trade to the last. Large trades pay for their power whenever they happen.
Either it takes more than 1% of the pool's reserve in this block, or it turns around your own last trade within a longhour. The board shows the receipt before you trade.
No. There is no setter, no pause and no upgrade in either contract.
Every test runs on a fork of Ethereum mainnet, against the live Uniswap PoolManager, Universal Router and PositionManager.
Every line of the rubric. Each power bracket, slicing inside a block, both automation windows, and the quote matching the receipt.
The books. 128,000 random calls a run (buys, sells, exact in and out, hundreds of blocks passing, claims, graph funding, owner payouts): the hook's ETH always equals what the owner, the holders and the graph are owed, to the wei.
The cap. No trade in any run ever paid more than 15%.
The launch. Only the owner's wallet can create the one pool the hook binds.
No owner powers. The owner chose the opening price once and receives 0.4% of volume. collect pays it; anyone may call it.
No setter, pause, upgrade or withdraw in either contract. Every tier, split, cap and recipient is final.
Not audited. Read the source. Every rule is in the hook's header comment, and the narrative is in the token's.
