Python binding to the Solana Rust SDK

---

Solders

solders is a Python binding to the Solana Rust SDK. It provides robust, high-performance solutions to core Solana tasks such as transaction signing and serialization, and saves us from reimplementing Solana logic in pure Python.

Installation

pip install solders

Note: Requires Python >= 3.7.

Example Usage

>>> from solders.message import Message
>>> from solders.keypair import Keypair
>>> from solders.instruction import Instruction
>>> from solders.hash import Hash
>>> from solders.transaction import Transaction
>>> from solders.pubkey import Pubkey
>>> program_id = Pubkey.default()
>>> arbitrary_instruction_data = bytes([1])
>>> accounts = []
>>> instruction = Instruction(program_id, arbitrary_instruction_data, accounts)
>>> payer = Keypair()
>>> message = Message([instruction], payer.pubkey())
>>> blockhash = Hash.default()  # replace with a real blockhash
>>> tx = Transaction([payer], message, blockhash)

Development
