Create a QR Code

QR generation is an optional dependency so RPC-only installations stay small.

pip install "solathon[qr]"

def create_qr(
    link: str,
    size: int = 10,
    background: str = "white",
    color: str = "black",
    border: int = 4,
) -> BytesIO: ...

size is the number of pixels per QR module, not the final image dimensions. The four-module default border is the standard QR quiet zone, and high error correction protects readability around the centered Solathon logo. Use a light background and dark foreground for reliable wallet scanning.

from solathon.solana_pay import create_qr, encode_url
 
url = encode_url(recipient=recipient, amount="0.01", memo="order-1042")
qr_image = create_qr(url)
 
with open("solana-pay.png", "wb") as output:
    output.write(qr_image.getvalue())

The returned BytesIO stream is positioned at byte zero and is ready for a web-framework response or file write.
