1//! `no_std` Solana SDK for ESP32 microcontrollers.
2//!
3//! Wallet creation (BIP39/SLIP-10), Ed25519 signing, transaction building,
4//! and JSON-RPC — all in ~163KB of flash on ESP32-C3.
5//!
6//! # Quick start
7//!
8//! ```toml
9//! [dependencies]
10//! esp-solana = { version = "0.1", features = ["wallet"] }
11//! ```
12//!
13//! ```rust,ignore
14//! use esp_solana::prelude::*;
15//! use esp_solana::wallet::Wallet;
16//! use esp_solana::instruction::system_transfer;
17//! use esp_solana::message::Message;
18//! use esp_solana::transaction::Transaction;
19//!
20//! let wallet = Wallet::generate_12(&entropy).unwrap();
21//! let keypair = wallet.keypair(0).unwrap();
22//!
23//! let ix = system_transfer(keypair.pubkey(), recipient, 1_000_000);
24//! let msg = Message::compile(keypair.pubkey(), &[ix], blockhash).unwrap();
25//! let tx = Transaction::new(msg, &[&keypair]).unwrap();
26//! let b64 = tx.to_base64();
27//! ```
28//!
29//! # Features
30//!
31//! - **`crypto`** (default) — Ed25519 signing via `ed25519-compact`
32//! - **`wallet`** — BIP39 mnemonic + SLIP-10 key derivation (enables `crypto`)
33//! - **`std`** — enables std for host-side testing
