✤ SybilDAO

Defending DeFi From Sybil Attacks

Verify your address at https://sybildao.com/#verify

Contracts are currently deployed on the Ethereum Goerli Testnet.

Main Contract Address: 0x7927BEa1eA84614DCeAECa1710cea8a7DeAa1d25

Developer Examples

For developers there are some integration examples at: https://github.com/0xD185/SybilDAO/tree/main/contracts/examples

ERC20 Airdrops
NFT Mints (ERC721 & ERC1155)
Simple Checks

Explainer

SybilDAO solves the problem of mass sybil attacks in DeFi in a streamlined way that is simple for blockchain developers to implement and has a great UX for end users.

A 3rd party developer can link off to https://sybildao.com/#verify from their dApp and then check to see if the users has verified their wallet address with a simple look up in solidity.

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.17;
 
interface ISybil {
    function check(address) external view returns (bool);
}
 
contract SybilDeveloperExample {
    address constant sybil = 0x7927BEa1eA84614DCeAECa1710cea8a7DeAa1d25;
 
    function test(address _address) external view returns (bool) {
        require(ISybil(sybil).check(_address),"Visit: https://sybildao.com/#verify");
        return true;
    }
}

Bot Protection

The system is designed to prevent mass bot attacks which plague airdrops and NFT mints. Here are some of the protections implimented:-

Cloudflare BOT protection
VPN/ToR/Botnet blacklists
Client side analysis
Transactional cost + gas fee
IP Restrictions
hCaptcha integration
ML Risk Analysis (TBC)

Once the frontend challenge has been completed an API provides a one time authorization code to the clients web browser. This authorization code along with a cryptographic proof enables the verification within the SybilDAO smart contract.

Partnerships

3rd party DeFi protocols can look up on-chain verified addresses from within their smart contract and get a true/false boolean response.

Whitelisted addresses are immutable and verifiable from any smart contract, these can be used across various DeFi partner promotions and campaigns.
