metaflux-client 0.9.0

//! Place a resting BTC bid against a local devnet node and print the returned
//! per-order status (oid if it rested, fill detail if it crossed).
//!
//! Targets a node at `http://127.0.0.1:8080`. The SDK signs against the
//! MTF testnet/devnet EIP-712 domain chain id (`MTF_CHAIN_ID` = 114514;
//! mainnet is 8964); signing against the wrong chain id makes the node
//! recover a different address and reject (401).
//!
//! Dev key (address `0x17c5185167401ed00cf5f5b2fc97d9bbfdb7d025`): pass
//! `MTF_PRIVATE_KEY=0x4242424242424242424242424242424242424242424242424242424242424242`.
//!
//! ```bash
//! MTF_PRIVATE_KEY=0x4242...4242 cargo run --example submit_limit_order
//! ```
