It's absolutely official. Lightspeed acquired Anvil last week and will keep Anvil alive for 6 months until Lightspeed has everything ex-Assent traders need in Anvil. I thought they were the obvious fit all along since they have the infrastructure to support it. I called Lightspeed and Assent and they both confirmed this with me. Call Lightspeed and they will direct you to trading groups who will be using Anvil. 100% confirmed, i did it today.
