"Who knows how much innovation we\u2019re going to stifle, who knows what kind of new apps never emerge," said Senator Pat Toomey. A compromise which proposed amending provisions in the bipartisan infrastructure deal on crypto failed to meet the requirements of a unanimous consent request in the Senate, making the bill likely to go to a full vote without additional changes.This afternoon, Senator Tom Carper, the Democratic floor manager for infrastructure bill HR 3684,\u00a0put forth the compromise amendment agreed upon earlier today by Senators Pat Toomey, Cynthia Lummis, Rob Portman, Mark Warner, Kyrsten Sinema and Ron Wyden on providing clarity for what defines a crypto broker. However, Alabama Senator Richard Shelby objected when Carper did not agree to add Shelby\u2019s own unrelated amendment to the bill \u2014 a proposal which would add $50 billion in defense funding.In just two words \u2014 \u201cI object\u201d \u2014 the Alabama lawmaker seems to have single handedly stopped the crypto amendment from being incorporated into the bill before a final vote. Though the infrastructure deal could still be modified in the House of Representatives if passed in the Senate, any amendment would require different lawmakers and likely different compromises.

The senator said miners, stakers, hardware and software providers, and software developers would likely be required to \u201cprovide information that they don\u2019t have and they can\u2019t get.\u201d\u201cAll I want to do is have a vote on an amendment that fixes this in a way that has bipartisan agreement, in a way that constrains this to apply narrowly to the people who are actually the intermediaries, running a centralized exchange, who have this information,\u201d said Toomey.He added:\u201cWe\u2019ll be back on this, because we\u2019ll do a lot of damage. Who knows how much innovation we\u2019re going to stifle. Who knows what kind of new apps never emerge. It\u2019s hard to predict what kind of completely impossible mandate results in, but it\u2019s not good, and it\u2019s going to bring us back here trying to clean up a mess which we could have prevented.\u201dIt\u2019s unlikely there is a path forward for the crypto amendment in the Senate before going to a final vote this week. Should the bill pass, it would still need to go through the House before being signed into law by President Biden.
