Robinhood Chain is reportedly considering a system that would let traders pay extra to move transactions ahead in the processing queue. The Ethereum-based network is examining Arbitrum’s Priority Gas Auctions, according to an unnamed source cited on October 9. Robinhood has not announced a decision to adopt the technology.
Robinhood Chain is evaluating the newer ordering system developed for Arbitrum, the technology behind its network. The information came from a person familiar with the discussions who requested anonymity since the matter is private. Robinhood declined to comment, while Arbitrum developer Offchain Labs did not immediately respond.
Robinhood Chain currently handles transactions on a first-come, first-served basis. Under that approach, paying more does not move a trade ahead of an earlier submission. The network also never adopted Arbitrum’s previous paid-priority system, known as Timeboost.
If Robinhood adopts Priority Gas Auctions, users could attach an additional fee to individual transactions to compete for earlier processing. However, the report does not establish whether the company has approved the change or when a launch might occur. No proposed fee schedule for Robinhood Chain has been disclosed.
Arbitrum introduced Priority Gas Auctions on September 24, replacing Timeboost on Arbitrum One. The earlier model auctioned access to an express lane, giving successful bidders a 200-millisecond timing advantage. The replacement lets users bid for priority separately on each transaction instead of buying advance access.
On Arbitrum One, a typical 250-millisecond block has two ordering rounds lasting about 125 milliseconds each. Transactions already waiting at the start of a round compete according to their priority fees. A new transaction must wait for the next round, even if it offers a higher fee.
The rules also protect transactions carrying little or no priority fee from being delayed indefinitely. Arbitrum increases their place in the queue as they continue waiting. Its documentation identifies arbitrage trades, loan liquidations and other time-sensitive activity as common reasons to pay for faster ordering. Users can still submit ordinary transactions without paying an additional fee for priority.
Robinhood launched the public mainnet of Robinhood Chain on July 1 to support financial services and tokenized assets. Its network allows developers to build trading, lending and other applications using blockchain infrastructure. Tokenized stocks are one part of Robinhood’s broader move toward around-the-clock financial markets.
According to DefiLlama, Robinhood Chain held approximately USD 1.04 billion in decentralized finance total value locked on October 10. It ranked among the ten largest blockchains by this measure, with activity spanning trading and lending applications. Any change in transaction ordering would therefore affect an active network rather than a planned launch.
Robinhood’s brokerage business also earns money through payment for order flow, where market makers pay for customer trade orders. Priority fees work differently since traders pay to improve their position in a blockchain transaction queue. Arbitrum says its private transaction queue prevents users from moving ahead of trades after their ordering becomes public.
For now, the potential switch remains a reported internal evaluation, not a confirmed Robinhood Chain upgrade. Neither a rollout date nor details of how any priority fees would be distributed have been made public.
