Robinhood Chain Evaluates Paid Transaction Priority System
Robinhood Chain weighs paid transaction ordering
Robinhood Chain, the blockchain built by Robinhood for tokenized financial assets, is evaluating a system that would let traders pay a fee to get their transactions processed ahead of others. The technology is being developed by Arbitrum, which provides the infrastructure behind Robinhood Chain.
According to a person familiar with the matter, Robinhood Chain is looking at Arbitrum's newer Priority Gas Auctions model. This system replaced Arbitrum's original "Time Boost" technology on September 24. The source spoke on condition of anonymity because the matter is private.
How paid priority ordering works
Robinhood Chain currently uses a first-come, first-served system for ordering transactions and has not used Arbitrum's original Time Boost offering.
Paid transaction priority works differently from Robinhood's traditional brokerage business, which earns money through "payment for order flow" — a practice where market makers pay brokers to route customer trades to them. On a blockchain, paid priority gives traders a speed advantage by enabling faster transaction processing.
Arbitrum's original Time Boost gave users a 200-millisecond head start in transaction sequencing. The new Priority Gas Auctions model instead allows traders to pay higher fees to have individual transactions processed ahead of others.
Competitive advantage and MEV protection
A faster trading connection could help professional firms compete for trading opportunities that can disappear in fractions of a second. Such speed advantages have long existed in high-frequency trading on Wall Street.
The article also notes that applying fee-based transaction ordering to blockchains could help prevent "maximum extracted value" (MEV), a form of frontrunning on transparent blockchains where traders exploit knowledge of pending transactions. This could level the playing field for entities seeking faster execution.
Robinhood Chain's rapid growth
Since launching its Ethereum-compatible network in July, Robinhood Chain has surged in popularity and entered the top 10 list of blockchains ranked by total locked value.
No comment from Robinhood or Arbitrum
