Robinhood Chain weighs paid transaction priority with Arbitrum's PGA
- —Arbitrum replaced Timeboost with PGA on September 24, 2026
- —Timeboost gave payers a 200 ms edge; PGA auctions queue position
- —Robinhood Chain has ranked in the top 10 chains by TVL since July 2026
- —PGA is pitched as MEV protection, but critics warn of retail disadvantage
Why it matters: Adoption would set a precedent for paid priority on L2s and reignite debate over fairness in on-chain trading.
