⚡ Lightspeed
One request. We build the trade, sign it with your Lightspeed wallet, which lives on our server, and hand it to every one of Robinhood's addresses at the same instant. No unsigned transaction comes back to you, no second call to send it, no RPC on your side, and none on ours either: the whole path from request to Robinhood runs on what the box already knows.

Why it lands first
- No round-trip. The Buy & Sell API needs three hops: build, sign on your machine, send. Here it is one process on a box that peers with the chain, and building and signing take about a millisecond.
- Nothing asked of the chain on the way. Every Pons launch, every curve's reserves, every graduated pool's price and liquidity live in memory, kept current from Robinhood's feed and the chain's logs. The quote, the minimum out, the nonce and the gas price are all local. A trade does zero reads.
- Every Robinhood address at once. The signed transaction goes to every one of Robinhood's addresses in parallel; the first acceptance answers your request and the others finish in the background. One transaction, one nonce, one fill: there is nothing to race against yourself.
- Asset-priced tokens in one transaction. A token priced in USDG, NVDA, ORBIO or any other quote asset is bought with ETH and sold back to ETH in a single transaction through the Lightspeed router, with the ETH leg routed over the best of Uniswap v4 and v3.
- The tape, as Robinhood orders it. The stream fans out every Pons launch and trade from the same box the moment Robinhood orders it, before any node serves the block, with the launch's token and curve address predicted from the launch call.
What it covers
Pons v2 tokens: on the bonding curve and in the Uniswap v4 pool after graduation, priced in ETH or in any of the quote assets Pons supports. Anything else on Robinhood Chain (Pons v1, Flap, Bags, a plain Uniswap token) is built by the Buy & Sell API next door and signed and sent the same way; the response says so with "engine": "builder".
