16//! DeFi (Decentralized Finance) domain model.
17//!
18//! This module gathers all constructs required to model on-chain markets and decentralised
19//! exchange (DEX) activity.
20//!
21//! • `chain`    – Blockchain networks supported by Nautilus (Ethereum, Arbitrum, …).
22//! • `token`    – ERC-20 and other fungible token metadata.
23//! • `dex`      – DEX protocol definitions (Uniswap V3, PancakeSwap, …).
24//! • `data`     – Domain events & state snapshots that flow through the system (Block, PoolSwap).
25//! • `types`    – Numeric value types (Money, Quantity, Price) shared across the DeFi layer.
26//! • `rpc`      – Lightweight JSON-RPC helpers used by on-chain adapters.

56/// Number of decimal places used by the native Ether denomination.
57///
58/// On the EVM all ERC-20 balances are expressed in **wei** – the
59/// smallest indivisible unit of Ether, named after cryptographer
60/// Wei Dai. One ether equals `10^18` wei, so using 18 decimal
61/// places is sufficient to represent any value expressible on-chain.
62///
63/// Tokens that choose a smaller precision (e.g. USDC’s 6, WBTC’s 8)
64/// still fall below this upper bound.
