White Paper 2.0, Two State Forks, Imitation Projects Emerge: What Happened to Sato Overnight?

Original author: KarenZ, Foresight News

On the evening of May 7, 2026, amid market skepticism regarding the pricing drift of sato's trading on Curve and its divergence from secondary market prices, the sato official website has updated its whitepaper portal to "whitepaper 2.0," and the front-end trading panel has simultaneously changed from "buy/sell" to "mint/burn."

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

At the same time, sato's market cap has fallen from its peak of nearly $40 million yesterday to $14.4 million. Meanwhile, the fork project sat1 has also released its own whitepaper and front-end website, reaching a market cap of $10 million at midday before falling to around $5.2 million.

It is important to note that currently both sato and sat1 are in a highly volatile, sentiment-driven phase. The mechanisms may appear clever, but this does not guarantee they will operate as designed. No mechanism innovation can substitute for risk management; participants should still make cautious decisions based on their own risk tolerance.

What Changed in the Sato Whitepaper 2.0?

The core of version 1.0 described an exponential issuance curve, a selfDeprecated mechanism at 99% supply (permanently disabling the mint function), no pre-mining, no allocation, no admin role, no upgrade path, and a rule that selling triggers burning.

Version 2.0 adopts a different writing approach. It is broken down into several distinct chapters: Issuance, Pool as Reserve, Curve Math & Constraints, Mint Halt, Trading Phases, Routing, and Trade Selection.

A crucial addition in the new version is the complete exposition of the three core formulas governing sato's Curve:

• Minted supply at accumulated ETH e: q(e) = K · (1 − e^(−e/S)), where K = 21,000,000, S = 500 ETH
• Unit price at position e: p(e) = (S / K) · e^(e/S)
• ETH to return when supply is q and burn amount is b: Δe(q, b) = S · ln((K − q + b) / (K − q))

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

The most important changes also include the following:

First, version 2.0 explicitly defines the existence of the 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 a separate V4 pool. Both share the PoolManager but are distinct pools.

Second, "sell" has been completely redefined as "burn." Although the old version mentioned that selling back to the Hook would burn tokens, version 2.0 highlights this separately: a supply reduction (burn) is triggered only when a user swaps sato -> ETH via the Curve pool. Conversely, if a user trades on the secondary sato/USDT pool, it is a standard AMM trade with LPs, which does not burn tokens or deplete the Curve reserve. This is a critical point: burning only occurs when selling into the Curve.

Third, version 2.0 incorporates "routing" into the whitepaper. The official website now clearly states that minting and burning on this site will directly call the satoSwapRouter, which is forced to interact with the Curve pool and will not automatically route to the secondary pool for a better price. This means the official front-end is not a "market-best price executor" but a "dedicated entry point into the Curve."

Fourth, the new front-end separates the three types of prices: market, burn, and mint. The new front-end visualizes these differences. Based on current official website data at the time of writing, the market price is approximately $0.7241, the burn price is about $0.7066, and the mint price is roughly $1.2. This means that minting via the official site's Curve today costs approximately 65% more than the secondary market price, while the burn price is very close to it. This effectively highlights the overnight controversy: the Curve mint price, Curve burn price, and secondary market price were never intended to be the same thing.

Fifth, version 2.0 revises the description of the "minting termination line." Version 1.0 explained the minting termination line as 99% of K, approximately 20.79 million sato, corresponding to about 2302 ETH. Version 2.0 rephrases it to sound more like a "market-accessible boundary," stating that "the practically attainable supply scale settles around 20.5 million sato," adding that this accessible supply decreases slightly as burning occurs. In other words, version 2.0 downplays the intuition that "users will naturally push supply to 20.79 million sato," emphasizing it as an attainable curve influenced by market behavior, rather than a linear process that must be completed.

What are the Similarities and Differences between the Fork Project sat1 and sato?

Meanwhile, the fork project sat1 has also launched a new whitepaper and front-end website with a similar structure.

Their core concepts are very similar:

• Both are ERC-20 tokens on Ethereum, issued directly via on-chain contracts, independent of team custody, upgrades, governance, or admin permissions;
• Both bind minting, burning, and reserves within the same curve mechanism;
• Both adopt the same type of asymptotic issuance curve: as cumulative ETH increases, new tokens become harder to mint, prices rise exponentially, approaching a 21 million cap without ever reaching it;
• Both charge a bilateral 0.3% friction fee, with the fee remaining within the Hook/Curve rather than going to the team;
• Both position themselves as "operatorless issuance machines," unlike traditional projects with roadmaps, upgrades, or team treasuries.

The key difference between them lies in "how state variables are recorded."

sat1's whitepaper points out that sato's issue is using two sets of states to drive the mechanism:

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

The buy path relies more on ethCum, while selling and self-deprecation (99% threshold) rely more on totalMintedFair. Compounded by an early-stage 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, and repeated buying and selling can exacerbate this drift.

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 single position.
• Self-deprecation is also determined directly from this single curve position.

Therefore, the essential mechanical difference is:

• Sato: In practice, issuance, exit, and halt determinations experience a "state split."
• sat1: Enforces a "unified state system," deriving all critical logic from a single curve position.

Regarding curve fees, while both charge 0.3%, in Sato, the whitepaper states that 0.3% is charged on every mint and burn, with fees permanently staying in the hook. The problem is that Sato has two key states – ethCum and totalMintedFair – which diverge after the early random multiplier. Consequently, the perceived "thickening of the reserve" is not solely due to the 0.3% fee but also includes an additional drift caused by the state discrepancy. In essence, the fee itself hasn't changed, but it has become conflated with state errors.

In contrast, in sat1:

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

This means sat1's 0.3% fee is also "kept in the pool," but it's designed solely to increase the reserve without interfering with the main curve state, as all core logic relies only on the single ethCum state.

Finally, it must be reiterated that no mechanism innovation can substitute for risk management. Participants should still make cautious decisions based on their own risk tolerance.
