Your AI. Your assets. Your call. Little John brings Robinhood Chain data and transaction review into AI desktop apps. You keep your keys and approve every wallet request.
Your AI. Your assets. Your call.
Little John lets you work with DeFi from your AI desktop workspace. Research, asset checks, market data, and transaction reviews stay in the same conversation, so you can move from a question to a decision without losing the context you have built.
Your private keys stay in your mobile wallet. Little John connects through WalletConnect, letting you use the wallet and assets you already have. You review the action on your desktop, decide whether to send it to the wallet, and approve it there separately. The AI cannot approve a transaction on your behalf.
We are starting with Robinhood Chain and Robinhood Wallet.
With Little John, you can:
- Check account assets and balances, including official Robinhood Stock Tokens
- View Stock Token/USDG pool prices and trade-history charts
- Inspect tokens and contracts
- Prepare USDG/Stock Token trades and review the required approvals
- See amounts, contract calls, fees, limits, and deadlines before continuing
- Inspect submitted transactions and their results
- Review personal messages and EIP-712 data before signing
Little John runs locally and keeps its own application state on your device. An interactive CLI provides access to the same tools for users who prefer a terminal.
Next, we plan to expand across Ethereum and other EVM networks, followed by other Layer 1 ecosystems such as Sui.
The idea is to keep your research and DeFi workflow together on the desktop while leaving your keys and final approval in your own wallet.
Little John started as an early project in a private repository and had not been published on npm.
After learning about the Buildathon, I focused on developing it into something people could install and use.
During the event, I added Stock Token/USDG pool-price cards using Uniswap v2, v3, and v4 data, improved how MCP App cards recover and display results, and gave users direct control over how they handle signature results.
I also brought these features together across the MCP App and CLI, and published the first version on npm.
The original repository history includes both the early work and the changes made during the Buildathon.
Bootstrapped. No external funding has been raised.
