GBPe is Monerium's e-money-licensed pound stablecoin — the GBP counterpart to EURe, with the same direct-to-bank-rail settlement model for UK-denominated flows.
GBPe is issued by Monerium. Every USDC → GBPe swap on 4SIGHT is quoted on every connected venue at once; you always see the worst case you'll receive, and often get more.
