Struct brontes_pricing::SubGraphRegistry

source · 
pub struct SubGraphRegistry { /* private fields */ }
Expand description

Manages subgraphs in the BrontesBatchPricer module, crucial for DEX pricing.

SubGraphRegistry handles dynamic management and maintenance of verified subgraphs, representing various token pairs. It responds to changes in the DEX, like new liquidity pools or updates in existing ones, by extending or updating subgraphs accordingly.

The registry facilitates accurate price retrieval for specific token pairs based on their subgraphs. It also addresses situations where a pool in a subgraph is compromised, ensuring the integrity and accuracy of pricing information.

Mainly functioning within the BrontesBatchPricer system, it plays a key role in providing up-to-date and reliable pricing data in the decentralized exchange context.
