1//! The [`Client`] an app trades through, and what it stands on.
2//!
3//! - [`config`]: the venue endpoints, the clock and randomness.
4//! - [`relayer`]: relayer requests as values, their answers, and the sender.
5//! - [`chain`]: contract reads on HyperEVM.
6//! - [`deployment`]: contract addresses, the relayer origin and the EIP-712 domains.
7//! - [`error`]: why a client call failed.
8//!
9//! The client's reads are here too. Its writes live with their domains: the session key in
10//! [`crate::account::session`], trades and staking in [`crate::trade::writes`], deposits in
11//! [`crate::transfer::deposit`].
