Robinhood Chain, from a launcher's point of view

A token launch costs roughly three and a half million gas here, and the bill lands in fractions of a cent. A simple transfer is cheaper still. On Ethereum mainnet that same launch would be a serious expense; here it is a rounding error.

The practical consequence is that operations nobody would attempt on mainnet become ordinary. Sweeping dust off a dozen wallets, splitting a position across sixteen addresses, retrying a failed buy — all of it is affordable, so the design constraint moves from cost to time.

This is the part that surprises people who came from Ethereum. The sequencer processes transactions first-come, first-served. Paying more gas does not move you up the queue, because there is no queue to bid on.

Every optimisation therefore aims at latency rather than price. Sign transactions before you need them. Send without waiting for a receipt. Keep the network round-trips out of the critical path. A strategy built on priority fees simply has nothing to grip here.

Funds arrive over the canonical Arbitrum bridge and take roughly ten minutes. The address is the same one you use everywhere else, which is exactly the trap: the same address on Ethereum, Arbitrum and Robinhood Chain holds three separate balances, and sending to the wrong one puts the money somewhere the tools on this chain cannot see.

It is recoverable — the keys are the same — but it is an afternoon of annoyance that a moment of attention avoids.

Cheap gas plus arrival-ordered execution favours preparation over spending. The team that has signed everything in advance lands ahead of the team that is still calling the network when the moment arrives, regardless of what either is willing to pay.
