The 100ms Spec, in Robinhood’s Own Words
Robinhood built its own chain, and it published a number to go with it. Per the spec Robinhood publishes at robinhood.com/us/en/chain, Robinhood Chain targets 100ms blocks.
That figure is Robinhood’s, stated by Robinhood, about Robinhood Chain. Nobody else gets to claim it.
The chain is a Layer 2 built on Arbitrum Orbit. It is not the Robinhood brokerage app, and it is not stocks. It is a separate piece of infrastructure with its own block cadence, and that cadence is the whole story here.
Per Robinhood’s own spec, 100ms is fast by any chain’s standard. Fast blocks change what a trader can reasonably expect from the tools sitting between them and the chain.
What Fast Blocks Change for a Trader
Block time sets the rhythm of the chain. A 100ms rhythm, again per Robinhood’s own spec, means state updates arrive in a tighter loop than most traders are used to.
That does not automatically make anyone a better trader. It changes what the surrounding tools need to handle without falling behind the chain’s own pace.
Price can move across a handful of blocks. On a chain built around Robinhood’s 100ms cadence, a handful of blocks is not much time at all, which is exactly the point of publishing that number in the first place.
A trader watching a chart and typing an order by hand is working against whatever blocks passed while they typed. That is not a knock on manual trading. It is just math about what a fast block time does to a reaction window.
A trading bot pointed at a chain like this needs order types that do not require a human to watch every block. It needs to sit in the same place traders already are, so there is no extra hop between decision and execution.
For most active traders on Robinhood Chain right now, that place is Telegram.
Limit Orders on a Chain That Does Not Wait
Banana Gun‘s Telegram bot supports Robinhood Chain, and limit orders are part of that support. You set a price, the bot watches, the order fires when the market reaches it.
That matters more on a chain moving in 100ms increments, again Robinhood’s stated figure, because the gap between “I should sell” and “I actually sold” is where discretionary traders lose ground to the clock.
A standing limit order does not blink. It sits there through however many blocks pass, at whatever pace Robinhood’s own 100ms spec sets for them, until price meets condition.
The same idea covers an exit as much as an entry. Set a target before you close the laptop, or set automated buying on liquidity detection to catch a launch as it forms.
Either way, the order sits ready instead of waiting on you to be at your screen for the right block.
“Faster execution” also came up when Banana Gun’s Robinhood Chain support went live, as a feature label describing that support. It is not a number, and it is not a race against Robinhood’s own block spec.
Robinhood Chain trades run through the Telegram bot right now, one interface, one order flow, no separate app to juggle mid-trade.
I have watched enough chains launch to know the tooling gap shows up fast. Either the bot supports the order type you need on day one, or you are manually timing entries against a clock you cannot see.
What Keeping Up Means Here, and What It Does Not
Keeping up with a chain running on Robinhood’s own 100ms cadence, in this context, means one thing: Banana Gun‘s Telegram trading bot is live on Robinhood Chain with limit orders working today, not on a roadmap.
It does not mean Banana Gun has published a matching millisecond figure of its own. It has not, and this piece is not going to invent one to sit next to Robinhood’s, or turn “keep up” into a stopwatch comparison.
There is no lap-time claim here. Robinhood’s 100ms describes its chain’s blocks. Banana Gun’s contribution is availability, working order types, and a bot that meets traders where they already are.
If you want to see the order types in question, a browser-based terminal lays them out alongside the Telegram flow. Either way, the chain moves at Robinhood’s stated 100ms. The bot’s job is to be present and ready when it does, nothing faster claimed.
Start with Banana Gun if you are setting up on Robinhood Chain for the first time.
