Dan Romero states that MPP is an open payment protocol supporting four payment methods across crypto and fiat, with no fixed 1.5% fee and an IETF web standard submission already filed.
Dan Romero further clarified that MPP is an open, scalable, payment-agnostic protocol that currently supports four payment methods across crypto and fiat. He said the system already supports Bitcoin Lightning, includes a draft for Solana expansion, and does not impose a fixed 1.5% fee. Romero also said the proposal has been submitted to the IETF as a web standard, reinforcing MPP’s positioning as a broader internet payment protocol rather than a single-network product.
