White Paper 2.0, Two-State Fork, Clone Project Surge: What Happened with Sato Overnight?

Original author: KarenZ, Foresight News

On the evening of May 7, 2026, amid market concerns regarding the pricing drift of sato on Curve, its divergence from the secondary market price, and other issues, the sato official website updated the whitepaper entry to "whitepaper 2.0". The front-end trading panel has also been simultaneously updated from "buy/sell" to "mint/burn".

This is not an ordinary revision of wording. Comparing version 1.0 with 2.0 reveals that the focus of the official overnight rewrite was not on sentiment or narrative, but on clarifying market understanding of how sato is actually traded, under what circumstances it is burned, and why the official website price differs from the secondary market price.

Meanwhile, sato's market capitalization has dropped from a high of nearly $40 million yesterday to $14.4 million. On the other hand, the copycat project sat1 has also released its own whitepaper and front-end website. Its market capitalization briefly reached $10 million at midday but has now fallen to around $5.2 million.

It is important to note that both sato and sat1 are currently in a phase of high volatility and high emotion-driven activity. The mechanisms may seem intricate, but this does not mean the market will operate as designed. Mechanism innovation cannot replace risk management. Participation still requires careful decision-making based on one's own risk tolerance.

What changed in the sato Whitepaper 2.0?

The core of version 1.0 described an exponential issuance curve, the selfDeprecated mechanism (permanent closure of the buy/mint function) at 99% supply, no premine, no allocation, no admin role, no upgrade path, and the rule that selling triggers a burn.

Version 2.0 adopts a different approach. It is divided into several clear chapters: Issuance, The Pool as a Reserve, Curve Mathematics and Constraints, Mint Cessation, Trading Phases, and Routing and Trade Execution.

A very important addition in the new version is the explicit listing of the three core formulas governing sato's Curve:

• Minted supply when cumulative ETH is e: q(e) = K · (1 − e^(−e/S)), where K = 21,000,000, S = 500 ETH
• Price per unit when at position e: p(e) = (S / K) · e^(e/S)
• ETH returned when current supply is q and burn amount is b: Δe(q, b) = S · ln((K − q + b) / (K − q))

These three formulas clearly articulate the operating logic of sato's Curve: the first defines how cumulative supply is generated, the second determines the price at minting, and the third determines how much ETH the Curve should return upon burning. In other words, sato's issuance, pricing, and redemption are not three separate sets of logic, but three facets of the same curve.

The most significant changes include the following:

First, version 2.0 explicitly recognizes the existence of a secondary market as a core part of the market structure. The bonding curve is a Uniswap V4 pool with hooks, while the sato/USDT secondary market is another independent V4 pool. Both share the PoolManager but are not the same pool.

Second, "sell" has been completely rewritten as "burn". Although the old version mentioned swapping back to the Hook triggering a token burn, version 2.0 isolates this point for clarity: a supply-reducing burn is only triggered when a user converts sato back to ETH via the Curve pool. Conversely, if a user transacts through the secondary sato/USDT pool, it is merely an AMM trade with LPs, which does not burn tokens or utilize the Curve reserve. This is a critical distinction; only selling into the Curve triggers a burn.

Third, version 2.0 introduces "routing" into the whitepaper. The official website now clarifies that minting and burning on this site will directly call the satoSwapRouter, which forces transactions through the Curve pool and will not automatically route to the secondary pool for better pricing. In other words, the official front-end is not a "market-wide optimal executor" but rather a "directed entry point into the Curve."

Fourth, the new front-end separates three distinct prices: market, burn, and mint. The updated front-end visualizes this difference. Based on current data from the official website, at the time of writing, the market price is approximately $0.7241, the burn price is approximately $0.7066, and the mint price is approximately $1.2. This means that minting via the official Curve currently costs around 65% more than the secondary market price, while the burn price is very close to the secondary market price. This effectively presents the overnight controversy upfront: the Curve mint price, the Curve burn price, and the secondary market price are inherently different concepts.

Fifth, version 2.0 revises the description of the "mint termination line". Version 1.0 described the mint termination line as 99% of K, approximately 20.79 million sato, corresponding to about 2302 ETH. Version 2.0 rephrases this as a "market-accessible boundary," stating that "the practically attainable supply scale will likely plateau around 20.5 million sato," and adds that this attainable supply will slightly decrease as burns occur. This means version 2.0 diminishes the intuitive notion that "users will naturally push the supply to 20.79 million sato," emphasizing it as an attainable curve influenced by market behavior rather than a linear process destined to complete.

What are the similarities and differences between the copycat sat1 and sato?

Concurrently, the copycat project sat1 has also launched a structurally similar new whitepaper and front-end website.

Their core concepts are very similar:

• Both are ERC-20 tokens on Ethereum, issued directly via on-chain contracts, without reliance on team custody, upgrades, governance, or admin keys;
• Both bind minting, burning, and reserves within the same Curve mechanism;
• Both employ the same type of asymptotic issuance curve: as cumulative ETH grows, minting new tokens becomes increasingly difficult, prices rise exponentially, approaching the 21 million cap asymptotically without ever reaching it;
• Both charge a bilateral 0.3% friction fee, which remains within the Hook/Curve rather than being directed to the team;
• Both position themselves as "operator-less issuance machines," unlike traditional projects with roadmaps, upgrades, and team treasuries.

The primary difference lies in "how state variables are tracked."

The sat1 whitepaper points out that sato's problem is using two sets of states to drive its mechanism:

• ethCum: cumulative ETH in the Curve;
• totalMintedFair: issued supply within the Curve.

The buy path relies more heavily on ethCum, while selling and the self-deprecation (99% threshold) rely more on totalMintedFair. When combined with the initial random multiplier, these two quantities no longer strictly maintain the same invariant, resulting in "one contract, two Curve positions."

This can cause ethCum to advance faster than totalMintedFair, with back-and-forth trading exacerbating this divergence.

In contrast, sat1's design rule is to maintain only one primary state.

• The contract stores only one Curve state: ethCum.
• Fair supply = Curve.totalMinted(ethCum).
• Price = Curve.marginalPrice(ethCum).
• Sell quotes are also derived from this same position.
• SelfDeprecated status is also determined by this same Curve position.

Thus, the essential mechanism difference is:

• sato: Issuance, redemption, and mint cessation decisions suffer from "state fragmentation" in practice.
• sat1: Enforces a "unified state system", deriving all critical logic from the same single Curve position.

Regarding Curve fees, while both charge a 0.3% fee, in sato, the whitepaper states a 0.3% fee is charged on each mint and burn, with the fee permanently remaining in the hook. The issue is that sato simultaneously uses ethCum and totalMintedFair as two crucial states, which diverge after the initial random multiplier. Consequently, the observed "thickening reserve" stems not only from the 0.3% fee but also incorporates extra deviation from state drift. In other words, the fee itself remains unchanged, but it becomes conflated with state errors.

In sat1:

• When buying 1.000 ETH, the mint quote is calculated using only 0.997 ETH, but the full 1.000 ETH enters the reserve.
• When selling, the user receives 0.3% less, and the deducted ETH remains in the Hook.

So, sat1's 0.3% fee also "stays in the pool," but is designed solely to thicken the reserve without interfering with the main Curve state, as all core logic recognizes only ethCum as the single state.

Finally, it must be reiterated that mechanism innovation cannot replace risk management. Participation still requires careful decision-making based on one's own risk tolerance.
