Doom, explained.

Doom AI is an AI trading agent for Robinhood Chain — an Ethereum L2 (Arbitrum Orbit, chain id 4663, gas paid in ETH). It turns a sentence into a ready-to-sign swap or bridge, so you can move between crypto and tokenized US stocks without hunting for pools, routes or contract addresses.

Doom is non-custodial. It never holds funds, never sees your private keys and never sends a transaction on its own — every action is signed by you, in your wallet.

Doom is a conversational layer on top of the best on-chain liquidity available to Robinhood Chain:

• Swaps — crypto ⇄ crypto, crypto ⇄ Stock Tokens (NVDA, AAPL, SPY…) and stock ⇄ stock, routed through Uniswap v2/v3/v4 pools.
• Bridges — Robinhood Chain ⇄ Ethereum, Arbitrum, Base, Optimism, Polygon and BNB Chain via LI.FI (Across, Relay, Stargate and more), including bridge-and-swap in one step.
• Safety by default — ambiguous tickers are never guessed, decimals are read on-chain, and approvals are for the exact amount only.

1. You type a request. “Swap 0.05 ETH for NVDA” or “Bridge 50 USDC from Arbitrum and swap it into AAPL”.
2. Doom resolves tokens. It searches the token lists, shows you candidates if a ticker is ambiguous, and reads decimals directly from the contract.
3. Doom checks balances and quotes. Uniswap's Trading API for same-chain swaps (LI.FI as a fallback), LI.FI for bridges.
4. You review a plan card. Amount in, expected and minimum out, price impact, fees, gas, ETA and any warnings (balance shortfall, impact > 3%, third-party recipient).
5. You sign. Approve (exact amount) → sign the Permit2 message if needed → send the swap or bridge. For bridges, Doom tracks the transfer until it lands.

Doom adds nothing on top of the route today. Every cost is shown on the plan card before you sign — the number you see is the number you pay.

Contracts Doom interacts with

Uniswap Universal Router · Robinhood Chain

0x204FAca1764B154221e35c0d20aBb3c525710498

Any swap transaction that does not target this router is refused before it reaches your wallet. Bridge transactions use the contract returned by the selected LI.FI route, shown in your wallet before signing.

DoomAI is the chat app where it all happens. Connect a browser wallet (MetaMask, Rabby, Robinhood Wallet extension), switch to Robinhood Chain when prompted, and tell Doom what you want.

Stock Tokens are tokenized exposure to US equities, not brokerage shares, and may be unavailable in your jurisdiction. Doom does not give investment advice.
