//! # Abstract Api Base
//!
//! `abstract_std::adapter` implements shared functionality that's useful for creating new Abstract adapters.
//!
//! ## Description
//! An Abstract adapter contract is a contract that is allowed to perform actions on a [proxy](crate::proxy) contract.
//! It is not migratable and its functionality is shared between users, meaning that all users call the same contract address to perform operations on the Account.
//! The api structure is well-suited for implementing standard interfaces to external services like dexes, lending platforms, etc.
