Identification Methods

Identification Events

*Pseudocode
Name - Unisocks Edition 0 holders
ID - (Base64 string)
Project Name - Uniswap
Contract - 0x23b608675a2b2fb1890d3abbd85c5775c51691d5
Original Data registry - Ethereum
Analyzing Method - > if(asset balance >0){isOwner = true;} else {isOwner = false; }
*Pseudocode
Name - Transaction times with UniswapV2Router02
ID - (Base64 string)
Project Name - Uniswap
Contract - 0x8ad599c3A0ff1De082011EFDDc58f1908eb6e6D8
Original Data registry - Ethereum
Analyzing Method -> {return Interaction times with 0x8ad599c3A0ff1De082011EFDDc58f1908eb6e6D8 of this wallet}

Identity Scoring Algorithm

*Pseudocode
Name — Uniswap loyal user score
ID — (Base64 string)
Formular - f(x)= if(Event1_value=true,100,0) +10*Event2_value
