Description

Chord: Trade every asset with superintelligence.
A trading app for humans and their AI agents, built on Robinhood Chain.

Stocks are on-chain now, but buying one still takes a wallet, a bridge, gas, a DEX and a dozen news tabs. Chord turns that into one balance and one slide.

- Cash: one dollar balance, USDG on Robinhood Chain. Add USDC or USDG from Arbitrum and other networks with one signature. The wallet stays the user's own.
- Any asset: buy 192 of Robinhood Chain's 195 stock tokens, plus crypto and memes, straight from Cash with one slide. No gas, no wallet pop-up.
- AI Copilot beside the Buy button: ask why a price moved and get an answer from the news, X and on-chain trades, every claim dated and sourced. Set alerts in a sentence, or have it draft an order you approve.
- The same Cash goes further: long or short on perps (Lighter on Robinhood Chain) and Earn on idle Cash (Morpho USDG vault).

Our own engine underneath: a live index of every swap on Robinhood Chain, a DEX aggregator that splits each order across 17 DEXs on Robinhood Chain and Arbitrum, and our verified ChordRouter. A $1,000 Tesla buy moves the price 0.03%, the best route takes 0.04 s, and a real order went from slide to bought in 3.4 s. Other apps and AI agents use the same APIs (REST, MCP, Agent Skill).

Progress During Hackathon

- Shipped the Chord iOS app alongside the web app. - Moved Cash to USDG on Robinhood Chain: every user holds USDG, and a stock buy is one swap. - Cross-chain trading through Arbitrum: deposits from Arbitrum in one signature ($20 USDC in, $19.95 USDG out), and Arbitrum tokens trade from the same Cash. - Deployed ChordRouter on Arbitrum One and extended the DEX aggregator to 17 DEXs on Robinhood Chain and Arbitrum. - Added Perps on GMX V2 (Arbitrum) to the app: long or short 100+ markets up to 10x, paid from the same Cash. A $4 ETH long opened in about 10 seconds and closed back to Cash in about 8. We first built Perps on Lighter (Robinhood Chain), then moved them to GMX. - Added Earn (Morpho USDG vault) to the app. - Put an AI Copilot on every token page. - Fast trades: no wallet pop-up, gas covered, and a stock buy lands in under a second.
