Substreams Ethereum Ambient Module

Modules Description

map_pool_changes

• Type: Map
• Purpose: This module detects new pools within the Ethereum blockchain and balance changes.
• Inputs: Ethereum block data (sf.ethereum.type.v2.Block).
• Output: Emits data of type proto:tycho.evm.state.v1.BlockPoolChanges.

store_pools_balances

• Type: Store
• Purpose: Accumulates and stores the balances of pools detected by map_pool_changes. It uses an additive update policy, implying that new values are added to existing balances.
• Inputs: Data mapped by map_pool_changes.

store_pools

• Type: Store
• Purpose: Maintains a store of pool information using the ProtocolComponent data structure. This store is updated whenever map_pool_changes emits new pool data.
• Inputs: Data mapped by map_pool_changes.

map_changes

• Type: Map
• Purpose: This module integrates all the processed information to generate comprehensive BlockContractChanges. It considers new pools, balance changes and contract changes.
• Inputs:
  • Ethereum block data (sf.ethereum.type.v2.Block).
  • Data from map_pool_changes.
  • Data from store_pools_balances.
  • Data from store_pools.
• Output: Emits proto:tycho.evm.state.v1.BlockContractChanges.
