sato mechanism design

According to an Odaily report, sato is an ERC-20 token deployed on the Ethereum mainnet, built based on the Uniswap v4 Hook architecture. It has no pre-mining, no team allocation, no administrator privileges, and also no upgrade or pause functions; the system operates automatically through on-chain contracts.

sato uses a Bonding Curve issuance mechanism. After users pay ETH to the Hook contract, the system automatically mints tokens according to a fixed mathematical formula. ETH is permanently stored in the Hook contract as system reserves. sato’s theoretical maximum supply is 21 million tokens. When the supply reaches 99% (8B minus 8B, i.e., 20.79 million), the system stops further minting. After that, users can still sell sato back to the system to receive ETH, and the sold-back sato is directly burned. The system charges a 0.3% fee on buy and sell transactions; the fee is permanently stored in the Hook contract and cannot be withdrawn.

According to a BlockBeats report on May 8, 2026, sat1 is described as an improved version of the sato mechanism, and it also uses the Uniswap v4 Hook architecture.

BlockBeats: On-chain rotation trend and liquidity constraints

According to a BlockBeats report on May 8, 2026, uPEG, sato, and sat1 have appeared one after another on the Ethereum mainnet. BlockBeats noted that the rapid rotation of these third-generation tokens makes it difficult for the market cap of any single token to continuously expand. Ethereum mainnet gas fees and the scale of on-chain liquidity, therefore, impose constraints on the market-cap ceiling for tokens of this type.
