On-chain finance fears more than just high transaction fees. Even if you place an order first, bots can outbid you on Gas to cut in line, and prices might get manipulated before execution. Robinhood Chain uses a 'first-come, first-served' ordering system: the order in which transactions reach the sequencer determines their priority—paying extra won’t let you jump the queue. This makes scenarios like stock tokens, lending, and staking more predictable in terms of execution outcomes, while reducing the layer of bidding wars. But this doesn’t mean MEV disappears. Bots can still compete on network latency, and the sequencer must undergo public verification. What it solves is pay-to-front-run, not all forms of front-running. For on-chain finance to embrace traditional assets, beyond speed, transaction ordering needs to feel like rules—not auctions.
