One-line SOL transfer from JSON wallet files on Solana

A minimalist Python package that enables sending SOL (Solana's native token) from a JSON-formatted private key file (exported from wallets like Phantom, Solflare, Backpack, etc.) using a single function call.

Perfect for automation scripts, bots, CLI tools, testing utilities, or any scenario requiring simple programmatic SOL transfers.

Features

• Extremely simple API: send_sol(json_path, to_address, amount_sol)
• Automatically handles rent-exempt minimum balance for new/uninitialized accounts
• Uses modern VersionedTransaction (MessageV0)
• Built-in sender balance check before transaction
• Supports custom RPC endpoints (mainnet, devnet, testnet, private nodes)
• Configurable commitment level for confirmation
• Prints Solscan link and user-friendly messages
• Optional automatic adjustment for rent-exempt amount

Installation

From PyPI (recommended for end users)

pip install easysolpay

Quick Start

from easysolpay import send_sol

# Basic transfer
tx_signature = send_sol(
    json_path="~/my-wallet.json",
    to_address="9xY8zQw...RecipientPublicKeyHere",
    amount_sol=0.42
)

print(f"Transaction sent: https://solscan.io/tx/{tx_signature}")

Sending to a new (uninitialized) account

# Small amount → automatically adjusted to rent-exempt minimum (~0.00089088 SOL)
send_sol(
    json_path="wallet.json",
    to_address="NewAccount11111111111111111111111111111",
    amount_sol=0.0001,                     # will be raised if needed
    # auto_adjust_for_rent=True            # this is the default
)

Testing on devnet (highly recommended before mainnet)

send_sol(
    json_path="devnet-wallet.json",
    to_address="RecipientOnDevnet...",
    amount_sol=1.0,
    rpc_url="https://api.devnet.solana.com"
)

Function Signature

send_sol(
    json_path: Union[str, Path],
    to_address: Union[str, Pubkey],
    amount_sol: float,
    rpc_url: str = "https://api.mainnet-beta.solana.com",
    commitment = Confirmed,
    auto_adjust_for_rent: bool = True
) -> str

Returns: the transaction signature as a string.
