Robinhood Chain Eyes Priority Gas Auctions for Faster Trades

Robinhood Chain, the Ethereum Layer-2 blockchain designed for tokenized real-world assets (RWAs), is reportedly considering a new transaction-ordering system that would allow traders to pay additional fees for faster trade execution.

According to a person familiar with the discussions, Robinhood Chain is evaluating Priority Gas Auctions, a technology developed by Arbitrum, which provides the blockchain infrastructure supporting the network. The potential integration could introduce a new approach to transaction processing as Robinhood expands its presence in decentralized finance and tokenized securities.

Arbitrum introduced Priority Gas Auctions on September 24, replacing its previous Timeboost transaction-ordering mechanism. Timeboost allowed users to purchase a 200-millisecond advantage when submitting transactions, giving certain traders earlier access to execution opportunities.

The updated system instead enables participants to bid higher fees to prioritize individual transactions. This approach could benefit professional traders competing for opportunities where milliseconds can significantly influence trading outcomes.

Robinhood Chain currently follows a first-come, first-served transaction-ordering model and has not implemented Arbitrum's original Timeboost system. Sources indicate that discussions surrounding the newer technology remain private, with no confirmed decision regarding its adoption.

Since launching its Ethereum-compatible blockchain in July, Robinhood Chain has experienced rapid growth, securing a position among the top 10 blockchain networks by total value locked (TVL).

The potential upgrade also reflects Robinhood's broader strategy of combining traditional brokerage services with blockchain-based financial markets operating around the clock.

Robinhood's brokerage business has historically generated revenue through payment for order flow, where market makers compensate brokers for directing customer trades to their platforms.

However, blockchain-based priority auctions operate differently by allowing traders to pay directly for transaction-processing advantages rather than purchasing customer order flow.

Supporters argue that structured priority mechanisms could help manage maximum extractable value (MEV), a practice involving transaction reordering and other strategies to capture additional profits.

Such systems may also create more transparent competition for execution speed, an advantage traditionally associated with high-frequency trading firms on Wall Street.

Robinhood declined to comment on the reported discussions, while Offchain Labs, the developer behind Arbitrum, had not immediately responded to requests for comment.
