Robinhood Chain, the popular Layer-2 blockchain tailor-made for tokenized real-world financial assets, is evaluating a transaction-ordering system that would allow users to pay a fee to prioritize certain trades, according to a person familiar with the matter.

The technology is being developed by Arbitrum, which provides the infrastructure behind Robinhood Chain. The system, which isn’t affiliated with the chain, had been offering a paid-for transaction-ordering technology called “Time Boost” that gives users a priority-sequencing advantage in the form of a 200-millisecond head start. However, on September 24, Arbitrum replaced its Time Boost transaction-ordering system with a new model, Priority Gas Auctions, that allows traders to pay higher fees to have individual transactions processed ahead of others.

It is this newer version of the tech that Robinhood Chain is understood to be evaluating, the person said, under the condition of anonymity because the matter is private.

Currently, Robinhood Chain uses a first-come, first-served transaction ordering policy and has so far not availed itself of Arbitrum’s original Time Boost application.

Since launching its Ethereum-compatible network back in July, Robinhood Chain has surged in popularity, entering the top 10 list of blockchains ranked by total locked value.
