Struct brontes_pricing::SubgraphVerifier

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

SubgraphVerifier Manages the verification of subgraphs for token pairs in the BrontesBatchPricer system. It ensures the accuracy and relevance of subgraphs, which are essential for pricing tokens on DEXs.

The struct performs several critical functions:

  • pending_subgraphs: Maintains a collection of subgraphs currently undergoing verification. These represent token pairs and are crucial for calculating accurate prices.

  • subgraph_verification_state: Tracks the state of subgraphs during the verification process. It includes information on pruned edges that did not meet liquidity parameters, helping to select edges with the highest liquidity in case of critical edges falling below the threshold.

  • create_new_subgraph: Generates new subgraphs for specific token pairs, adding them to the pending list for verification. This method is key in determining the relevant parts of the token graph for a pair.

  • verify_subgraph: Verifies subgraphs to ensure they accurately reflect the current state of the DEX, checking liquidity parameters and pool states. This method is vital in maintaining the integrity of the pricing system.
