A novel network saturation vector that exploits gas price mechanics through ERC721 tokens. The attack leverages market psychology and memetic value to transform network congestion into a desirable token property.

Value Mechanics

The Ethereum Thermal Index (ETI) creates a tradable representation of network congestion state. Each token’s ETI score - derived from the gas price at transfer - serves as an immutable proof of network state capture. The mechanism exploits the scarcity of high-congestion network states, creating a feedback loop where value derives from the very congestion the trading creates.

    mapping(uint256 => uint256) public lastTradeGasPrice;
    mapping(uint256 => uint256) public tokenValue;

    uint256 public constant ETI_MULTIPLIER = 100;

        _updateETI(tokenId);
    }

    function _updateETI(uint256 tokenId) private {
        lastTradeGasPrice[tokenId] = block.basefee;
        tokenValue[tokenId] = block.basefee * ETI_MULTIPLIER;
    }

    function getTokenMetrics(uint256 tokenId) public view returns (uint256, uint256) {
        require(_exists(tokenId), "Token does not exist");
        return (lastTradeGasPrice[tokenId], tokenValue[tokenId]);

}

Attack Vector

The mechanism exploits three core properties of the Ethereum network:

1. Base Fee Mechanics
   • EIP-1559 base fee as network congestion oracle
   • Automatic value adjustment through transfer hooks
   • Built-in market signal amplification
2. Market Psychology
   • ETI as proof of network state capture
   • High ETI scores as status markers
   • Natural market formation around congestion events
3. Network Effects
   • Self-reinforcing trading incentives
   • Positive feedback between congestion and value
   • Cross-market arbitrage opportunities

Execution Path

Deploy → Initial Distribution → Natural Price Discovery → Trading Cascade → Network Saturation

The attack progression is market-driven, requiring only initial deployment and basic liquidity. Network effects and trading psychology drive the subsequent stages autonomously.

Network Impact

The saturation effect scales with:

Impact = ƒ(token_supply, trading_frequency, gas_cost)

Critical mass achieved when ETI-driven trading consumes sufficient network capacity to drive sustained congestion, creating a persistent high-value state for existing tokens.

Attack Surface

Key characteristics that make this vector resilient:

1. Protocol Compliance
   • Standard ERC721 implementation
   • No consensus/protocol exploits
   • Difficult to justify protocol-level intervention
2. Market Camouflage
   • Indistinguishable from normal trading
   • No clear attack attribution
   • Resistant to targeted mitigation
3. Autonomous Operation
   • Self-sustaining after deployment
   • Driven by natural market forces
   • No ongoing attacker participation required

Mitigation Vectors

Limited by attack characteristics:

• Protocol-level gas mechanics modifications required
• Market interventions likely ineffective
• Social coordination defence impractical

Conclusion

The ETI mechanism demonstrates how market psychology can be weaponized to create network-wide attack vectors without protocol exploitation. The attack’s insight lies in transforming network congestion from a cost into a valued commodity, creating a self-reinforcing cycle of network degradation through standard market operations.
