Sato Whitepaper 2.0 Released Amid Market Confusion as Sat1 Fork Emerges

Original author: KarenZ, Foresight News

On the evening of May 7, 2026, amid market concerns regarding pricing drift in Sato’s Curve trades and divergence from secondary market prices, the Sato official website updated its whitepaper link to “Whitepaper 2.0,” and the frontend trading interface was simultaneously changed from “Buy/Sell” to “Mint/Burn.”

This is not a routine wording revision. Comparing 1.0 with 2.0, it’s clear that the official rewrite overnight focused not on sentiment or storytelling, but on clarifying market misunderstandings regarding how Sato is traded, under what circumstances it is burned, and why the official price differs from the secondary market price.

Meanwhile, Sato's market cap has dropped from yesterday's high of nearly $40 million to $14.4 million. On the other hand, the clone project Sat1 has also released its whitepaper and frontend website, with its market cap briefly reaching $10 million at noon and currently declining to around $5.2 million.

Please note that both Sato and Sat1 are currently in a phase of high volatility and strong emotional influence. Although the mechanisms appear sophisticated, this does not guarantee that the market will behave as designed. No mechanism innovation can replace risk management—please carefully assess your own risk tolerance before participating.

The core of version 1.0 consists of an index issuance curve, self-deprecation of the minting function at 99% supply (permanently disabling buying and minting), no pre-mine, no allocations, no admin role, no upgrade path, and a burn mechanism on sell.

Version 2.0 uses a different structure, breaking it down into clearly defined sections: Issuance, Pools as Reserves, Curve Mathematics and Constraints, Minting Stop, Trading Phase, Routing, and Trade Selection.

In the new version, a very important addition is the complete presentation of the three core formulas for sato in curve:

• The minted supply when accumulated ETH is e: q(e) = K · (1 − e^(−e/S)), where K = 21,000,000 and S = 500 ETH
• Price per unit at position e: p(e) = (S / K) · e^(e/S)
• When the current supply is q and the burned amount is b, the ETH to be refunded: Δe(q, b) = S · ln((K − q + b) / (K − q))

These three formulas clearly explain the logic behind Sato’s curve: the first defines how the cumulative supply is generated, the second determines the price during minting, and the third determines how much ETH the curve should return during burning. In other words, Sato’s issuance, pricing, and exit are not three separate systems—they are three facets of the same curve.

The most important changes also include the following:

First, version 2.0 explicitly recognizes the secondary market as a core component of the market structure. The bonding curve is a Uniswap V4 pool with a hook, while the sato/usdt secondary market is another separate V4 pool. Both share the PoolManager but are not the same pool.

Second, "sell" has been completely rewritten as "burn." Although the previous version mentioned that selling back to Hook would burn tokens, version 2.0 clarifies this as a distinct mechanism: token burning—and thus a reduction in total supply—occurs only when users swap sato back to ETH via the Curve pool. Conversely, if users trade through the secondary sato/USDT pool, they are simply engaging in an AMM transaction with liquidity providers; no tokens are burned, and no Curve reserves are utilized. This distinction is critical: only sales into the Curve pool trigger burning.

Third, 2.0 has formalized the "router" in its whitepaper. The official website now clearly states that all minting and burning on this site directly invoke the satoSwapRouter router and are mandatory to route through the Curve pool, without automatically switching to secondary pools for better prices. In other words, the official website frontend is not a "market-best execution engine," but rather a "dedicated entry point to Curve."

Fourth, the new frontend has separated the three prices: market, burn, and mint. The new frontend now visually represents these differences. Based on the current data on the official website, as of this writing, the market price is approximately $0.7241, the burn price is approximately $0.7066, and the mint price is approximately $1.20. This means that, currently, minting via the official website’s Curve costs about 65% more than the secondary market price, while the burn price is very close to the secondary market price. It essentially lays out an overnight controversy in plain sight: the mint price, burn price, and market price of the secondary pool are fundamentally not the same thing.

Fifth, version 2.0 rephrased the description of the "minting termination line." Version 1.0 defined the minting termination line as: 99% of K represents the minting termination line, approximately 20.79 million sato, equivalent to about 2,302 ETH. Version 2.0 shifted the wording to resemble a "market-accessible boundary," stating: "The actually attainable supply volume hovers around 20.5 million sato," and added that this accessible supply will slightly decrease as burns occur. In other words, version 2.0 downplays the intuitive notion that users will naturally drive supply to 20.79 million sato, instead emphasizing that this is a market-influenced attainable curve rather than a linear process that must inevitably be completed.

Meanwhile, the clone project SAT1 has also launched a new whitepaper and frontend website with a similar structure.

The core concepts of both are very similar:

• All are ERC-20 tokens on Ethereum, issued directly via on-chain smart contracts without reliance on team custody, upgrades, governance, or admin privileges.
• All minting, burning, and reserve operations are tied to the same curve mechanism;
• All use the same type of asymptotic issuance curve: as cumulative ETH increases, minting additional tokens becomes progressively harder, with prices rising exponentially, approaching but never reaching the 21 million limit;
• Both sides are charged a 0.3% friction fee, and the fees are not distributed to the team but retained within Hook/Curve;
• They position themselves as "operator-less issuance machines," rather than traditional projects with roadmaps, upgrades, and team treasuries.

The main difference between the two lies in how state variables are stored.

sat1 points out in the whitepaper that the issue with sato is that it uses two sets of states to drive the mechanism:

• ethCum: Cumulative ETH in Curve;
• totalMintedFair: The issued supply in the curve.

The buy path relies more on ethCum, while sell and self-deprecation (99% threshold) rely more on totalMintedFair. After adding random multipliers during the early stage, these two values no longer strictly maintain the same invariant, resulting in “one contract, two curve positions.”

This can cause ethCum to increase faster than totalMintedFair, and repeated buying and selling will exacerbate this discrepancy.

In contrast, sat1's design rule is to retain only one main state.

• The contract stores only one curve state: ethCum.
• Fair supply = Curve.totalMinted(ethCum).
• Price = Curve.marginalPrice(ethCum).
• The sell quote is also derived from this same level.
• selfDeprecated is also determined directly from this same curve position.

So the fundamental difference in mechanism is:

• Sato: In practice, the judgments for issuance, withdrawal, and cessation have resulted in a "state split."
• sat1: Enforce "unified state," deriving all critical logic from the same curve position.

Regarding Curve fees, although both charge a 0.3% fee, the whitepaper for Sato states that a 0.3% fee is charged on every mint and burn, and the fee remains permanently in the hook. The issue is that Sato maintains two critical state variables—ethCum and totalMintedFair—which diverge after the initial random multiplier. As a result, the observed "thickening of reserves" is not solely due to the 0.3% fee but also includes an additional offset caused by state drift. In other words, the fee itself has not changed, but it has been conflated with state inaccuracies.

And in sat1:

• When buying 1.000 ETH, the mint quote is calculated based on 0.997 ETH, but the full 1.000 ETH is deposited into the reserve.
• When selling, users receive 0.3% less, with the deducted ETH retained in the Hook.

In other words, 0.3% of sat1 is also "kept in the fee pool," but it is designed solely to increase reserves without affecting the main curve's state, as all core logic recognizes only ethCum as the state.

Finally, it must be emphasized that no mechanism innovation can replace risk management—please carefully assess your own risk tolerance before participating.
