SAGE is a Claude-powered DeFi agent in WhatsApp. Text it to trade tokenized stocks on-chain - no app, no wallet, no gas. Funds live in a smart account you can self-custody. Built on Robinhood Chain.
SAGE is a Claude-powered DeFi agent that lives in WhatsApp. You text it like a friend and it lets you trade tokenized stocks - TSLA, AMZN, PLTR, NFLX, AMD - on-chain on Robinhood Chain. No app to install, no seed phrase, no gas, no crypto knowledge required. It even replies in your language.
Crypto's real blocker has never been features - it's onboarding. Installing a wallet, backing up a seed phrase, buying gas, learning a dApp: every step loses people. The apps that smooth the UX usually cheat on safety, becoming custodial hot wallets. SAGE refuses that trade-off - it deletes the friction and keeps the security on-chain.
One message creates your on-chain wallet. Before you can trade, SAGE walks you through securing it: you set a password on a one-time web page, a key is generated in your own browser (SAGE never sees it), and on-chain ownership becomes yours. From that moment, SAGE can trade on your behalf but can never withdraw your funds - only you can. Self-custody, set up in seconds, with no secret ever typed into a chat.
What makes it work:
- Smart-account wallets with an on-chain Risk Guard. Your funds live in a contract that enforces trading limits in Solidity, so a compromised server can't drain a single wallet.
- Verified-token allowlist. SAGE only swaps a fixed set of verified tokens and refuses scam or unknown ones - enforced by the agent and on-chain by the wallet contract.
- Gasless. SAGE sponsors every transaction. You hold one address and never need ETH.
- Withdraw or export your key any time from a secure page, signed in your browser. Your key never leaves your device.
- An AI market analyst. The DEX analytics page gives a live market read and an "Ask SAGE" copilot that answers questions grounded in real on-chain pool data.
- Plain English, any language. Buy, sell, set alerts, and place limit orders just by chatting.
It runs on on-chain infrastructure we built and deployed on Robinhood Chain: SageDEX, a Uniswap-V2-style AMM; SageOracle, our own spot and TWAP price oracle; and SageAccount, per-user smart-account wallets - plus the Claude-powered WhatsApp agent. Not a wrapper over a custodial hot wallet; the trust lives on-chain.
Roadmap: fiat on/off-ramp so users fund with a card and cash out to a bank through a licensed partner - the last barrier, removed.
SAGE: DeFi that onboards like WhatsApp and secures like a smart contract - built so the next billion users don't have to learn crypto to use it.
Week 1:
- Deployed SageDEX on Robinhood Chain - SageFactory, SagePair, SageRouter (custom AMM)
- Integrated Meta WhatsApp Cloud API with a webhook server
- Built AI intent parsing with Claude tool-use
- Automatic wallet creation with encrypted key storage on first message
Week 2:
- Built SageOracle - original on-chain TWAP price oracle for 5 tokenized stock pairs
- Added the SAGE Risk Guard - price-impact, concentration, and spending-limit checks before every trade
- Wrote 23 Hardhat tests across SageFactory, SagePair, SageRouter, and SageOracle
- Added full NatSpec documentation to all contracts
- Built and deployed the live SAGE DEX frontend on GitHub Pages
- Deployed the backend on Railway with a real-time price keeper
Week 3:
- Built and deployed SageAccount + SageAccountFactory - per-user on-chain smart wallets with trading limits enforced in Solidity
- Moved every user's funds into their own on-chain smart account, with the Risk Guard enforced at the contract level
- Added gas sponsorship - SAGE covers all fees, so users hold a single address and never need ETH
- Shipped the self-custody claim flow - users take full on-chain ownership of their wallet from a WhatsApp message
- Added order management (limit orders, price alerts) and per-user spending limits
- Wrote on-chain test scripts validating the smart-account model end to end
