Non-custodial RWA + yield service for AI agents on Solana. Compare yields, quote/buy/sell tokenized US equities (Backed xStocks: NVDAx, AAPLx, TSLAx, SPYx) and tokenized treasuries (Ondo USDY, ~4.6% APY). Funds stay in your existing Phantom wallet — we never custody, never sign. The MCP returns unsigned Solana transactions plus a one-click Phantom sign URL. You sign in your wallet, our backend broadcasts via reliable RPC. 10 tools: compare_yields, list_yield_tokens, list_xstocks, quote_tokenized_stock, get_portfolio, track_tx, build_deposit_yield_tx, build_buy_xstock_tx, build_sell_xstock_tx, build_withdraw_yield_tx. Auth: Phantom Sign-In with Solana → API key (no email, no password, no JWT expiry). Try the live e2e at https://autoyield.org

Overview

Non-custodial RWA + yield service for AI agents on Solana

You hold the wallet. We hold nothing.

autoyield gives your AI agent the tools to find best on-chain yields, build buy/sell transactions for tokenized US treasuries and US equities, and track positions — but never signs anything itself. Every action returns an unsigned Solana transaction plus a one-click Phantom sign URL. You sign in your own wallet.

What it can actually do

Tool	What it does
`compare_yields`	Rank current USDC lending + tokenized-treasury yields across Solana, Ethereum, Base, Arbitrum (DefiLlama)
`list_yield_tokens`	List supported tokenized treasuries (Ondo USDY ~4.6% APY)
`list_xstocks`	List Backed xStocks (NVDAx, AAPLx, TSLAx, SPYx) with live Jupiter liquidity
`quote_tokenized_stock`	Live Jupiter quote for buying a tokenized US equity
`get_portfolio`	Snapshot any Solana wallet — SOL, USDC, every xStock and yield token, priced
`track_tx`	Check a Solana tx's confirmation status
`build_deposit_yield_tx`	Build USDC → USDY swap, return unsigned tx + sign URL
`build_buy_xstock_tx`	Build USDC → xStock swap
`build_sell_xstock_tx`	Build xStock → USDC swap
`build_withdraw_yield_tx`	Build USDY → USDC redemption

Quick start (3 minutes)

1. Get an API key — sign in with Phantom at https://autoyield.org/account.html. No email, no password — your wallet pubkey is your identity.

2. Paste config into Claude Desktop:

{
  "mcpServers": {
    "autoyield": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://autoyield-api.fly.dev/mcp",
        "--header",
        "Authorization: Bearer ak_YOUR_KEY"
      ]
    }
  }
}

**3.** Ask Claude: *"Compare USDC yield options on Solana"* or *"Build me a buy of $10 of NVDAx"* — Claude calls our tools, gives you a sign URL, you sign in Phantom.

### Architecture: how funds stay yours

The MCP server **never** has signing keys. The unsigned tx names your wallet as fee-payer; only your private key can produce a valid signature. Our backend acts as a reliable broadcast relay (Phantom's RPC drops Token-2022 + Jupiter txs silently), and verifies the signed tx's fee payer matches the wallet we built for before broadcasting.

### Why this matters now

- **Tokenized treasuries** (Ondo USDY, BlackRock BUIDL, Franklin BENJI) put real-yield assets on-chain. Holding 10k USDC at 4.6% APY ≈ $460/year. Most stablecoin holders don't realize this exists.
- **Tokenized US equities** (Backed xStocks, Ondo Global Markets) let non-US users buy NVDA/AAPL/TSLA on-chain via Jupiter. $300K-$3M liquidity per ticker.
- **AI agents** need scoped, non-custodial access to these. Generic agent wallets that hold custody are a regulatory time bomb. autoyield never holds keys.
