IExecutionAdapter
IExecutionAdapter
Interface for execution adapters that handle asset trading operations
Execution adapters are responsible for converting between the Orion protocol's underlying token and various asset types (ERC-4626 vaults, ERC-20 tokens, etc.). All buy/sell operations use the Orion underlying token as the base currency, regardless of the token standard of the target asset. The underlying token is defined in the OrionConfig contract and serves as the protocol's base asset.
