BlockBeats report, on March 20, Farcaster co-founder Dan Romero (previously joined Tempo) posted to clarify five misconceptions about MPP. Dan stated that MPP is not limited to Tempo only; the protocol is unrelated to payment methods and supports both cryptocurrencies and fiat currencies across any blockchain. It has already been extended to the Bitcoin Lightning Network, and a Solana extension draft is currently available.
In terms of cost, MPP has no inherent fees; specific costs depend on the blockchain or fiat channel used. In terms of openness, MPP is designed to be simple and scalable, and has already been submitted as a web standard to the IETF.
In addition, MPP supports both pay-per-request and session-based modes, with the latter ideal for continuous micropayments requiring high API speed; Dan also emphasized that MPP separates secure HTTP communication from payment channels, without relying on any specific smart wallet implementation or stablecoin.
