Bitcoin Merchant Pubkey

[tee_vee]

Is Square using the same pubkey for all merchants in the US for Bitcoin LN payments?

@tee_vee Welcome to the community. I did a search and this was all I could find on the pubkey.

Short answer: There’s no public documentation from Square stating that they use a single Lightning pubkey for all merchants or a separate one per merchant. Square’s Lightning integration is abstracted from merchants, and they manage invoice generation and key management internally within their system.

Hi @tee_vee  - I see this is your first post in the Square Community so I'd like to officially welcome you! 🎉👏 My name is Violet and I'm one of the Community Moderators. Nice to meet you 🙂

Here's the answer I received from the Bitcoin Product Team: Square Lightning payments are a custodial design, and the pubkeys are unique to the custodian (Square), but not to each merchant. 

I hope this answers your question, but please let me know if I can help with anything else!
