QR codes w/ the coin logo in the middle would be comfy, and I figure >50% of people are gonna be using mobile wallets. Catches the eye a bit more too.
Something like QRs spanning horizontally and then the plaintext addresses underneath each one.
Edit: oh yeah also if you use a Bech32 wallet (p2wpkh, address format is bc1xxxx) you’ll save like ~70% on TX fees compared to the legacy BTC address in the footer.
