If you work in payments, you know the pain. You've sent the payment. The customer says it never arrived. You're now combing through transaction hashes trying to figure out which onchain transfer corresponds to which invoice. But @Arc just shipped something that fixes this: Transaction Memos are now live on Arc Testnet. Here's what that actually means: Every payment rail in traditional finance has some form of structured reference (like an invoice number). Onchain payments have never really had this in a native way. Memo-enabled calls change that: → Attach invoice IDs, payout references or customer IDs directly to a contract call → Preserve sender attribution at the protocol level → Memo events only emit when the contract call actually succeeds This sounds like a small feature but it's not. It's the difference between a payment that says "0.5 ETH moved from address A to address B" and a payment that says "Invoice #4471, paid in full, from this customer, confirmed onchain."

Ethereum is the neutral rails that makes this possible. https://t.co/S3hsnKi77k

CZ: Ethereum's L2 strategy has a problem... "The L2s are extremely centralized. And the L2s don't contribute to the L1's."
