Autonomous DeFi.

Otto X is an agent-native DeFi platform. AI agents can swap, bridge, and invest on your behalf with a single wallet signature. No seed-phrase exposure. No gas management. No intermediate custody by Otto. The infrastructure composes three existing primitives — x402 + OKX Onchain OS + EIP-3009 — and the user feels magic.

Recipes — new

We chain the endpoints —
one payment, one dose of alpha.

Recipes chain multiple of Otto's live X Layer endpoints into one high-signal report. You sign once — Otto runs the chain server-side and returns one answer.

The one-call flow

Five steps → one HTTP call.

Traditional agent-driven DeFi is a five-step gauntlet of approvals, gas estimations, and failure modes. Otto X collapses it into a single request with one wallet confirmation.

Before · Legacy flow

Agent tries to swap 10 USDC → WETH for you

1
Expose your private key to the agent somewhere it can reach. Immediate fail.
2
Approve the token to the router. Separate tx, user pays gas.
3
Submit the swap. Another gas fee. Agent or user signs.
4
Track the tx, handle reverts, monitor slippage, watch for frontrunning.
5
Every approval stays open forever. Every step is a failure mode.
5 moving parts · seed exposure · open-ended allowances · manual gas
After · Otto X

Same agent. Same swap. One HTTP call.

1
Bootstrap (once per payer). A paid GET /sub-wallet ($0.01) provisions your TEE sub-wallet and returns its address. Cache it — same payer, same sub-wallet, forever. No provisioning without a real payment behind it.
2
One wallet confirmation. Sign x402 fee + an EIP-3009 TransferWithAuthorization note — exact amount, short time window, to = your sub-wallet. Modern wallets batch both into one prompt.
3
POST /auto-swap. Server pulls your USDC → your sub-wallet direct, tops up dust gas, executes via OKX DEX. HTTP 200 with every tx hash.
✓ No seed phrase. ✓ No open allowances. ✓ No gas management. ✓ Otto never holds funds.
Custody model

Three layers. Zero Otto-held funds.

The key insight: principal moves user → user's own sub-wallet, never through Otto. Otto pays gas + orchestrates, nothing more. You can empty the sub-wallet at any time via the escape hatch.

1
Your wallet
Holds your USDC / USDT principal. Your seed phrase, your keys — Otto cannot see or touch it. You sign EIP-3009 authorizations off-chain from here.
Self-custody · EOA / hardware wallet
2
Your Otto X sub-wallet
TEE-custodied inside OKX Onchain OS. The key never leaves the Trusted Execution Environment — neither Otto nor OKX staff can export it. Receives principal, executes ops, holds residuals.
TEE · idempotent · deterministic per payer
3
Otto X operator
Pays gas to broadcast your EIP-3009 authorization and dust gas top-ups. Never takes custody of your principal. The transfer is user → sub-wallet direct.
Hot wallet · gas-only · orchestration
✓
Signer binding. principalAuth.from must equal the x402 payer. No impersonation.
✓
Destination locked. principalAuth.to must equal your own sub-wallet. No drains.
✓
Amount + time bound. Exact value, specific time window. No open allowances.
✓
Replay protection. Nonce uniqueness enforced in DB + on-chain authorizationState.
✓
Protocol allowlist. Sub-wallets can only touch Aave V3, Lido, Compound V3, Morpho on vetted chains.
✓
Escape hatch. POST /auto-withdraw sweeps sub-wallet funds to any address, anytime.
✓
Idempotency. Every op has a (payer, op_type, body_hash) key. Safe to retry.
✓
409 fallback. Clients without EIP-3009 support still get a working two-step funds-required path.
See the power yourself

Feel what your agent just learned.

Every endpoint below is a new skill an AI agent can earn the right to use for a fraction of a cent. Connect a wallet, sign one tiny USDT0 payment on X Layer, and watch the superpower light up in real time — live news, KOL sentiment, on-chain research, a TEE-custodied sub-wallet, even a DEX swap — all behind a single signature.

USDT0 balance (X Layer)
—
Need USDT0 on X Layer? Bridge from any chain via OKX Bridge, or deposit from your OKX exchange account. Payments are ~$0.001–$0.01 each; a few dollars goes a long way.
Payment
$0.001 USDT0 (once)
The full one-call flow, end-to-end

Swap USDT0 → any X Layer asset.

Two prompts in your wallet, one HTTP call. The first signs an EIP-3009 principalAuth note that pulls your USDT0 principal directly into your TEE sub-wallet — never through Otto's hands. Otto checks it before asking for payment; the second prompt then signs the x402 fee — $0.05 USDT0 to Otto. The server tops up dust gas, executes via OKX DEX, and returns every tx hash. Connect above first.

Sub-wallet (X Layer)
—
We look up your sub-wallet via free /sub-wallet/preview as soon as you connect. If you don't have one yet, the panel above can provision it for $0.01 (select GET /sub-wallet and Pay & call).
USDT0 — X Layer's EIP-3009 principal asset
You'll sign
$0.05 fee + 1.00 principal = 1.05 USDT0 total

Yield Watch — Otto rebalances for you.

One signature, 30 days of autonomous rebalancing. Under a signed delegation, Otto moves your USDC between Aave V3 and Compound V3 on Base and Ethereum when the other venue sustains a meaningful APY gap. You stay in control: cap the maximum per move, cap the number of moves, pause or revoke any time. The delegation is scoped, on-chain-verifiable, and the worker only signs from your TEE sub-wallet (never from your external wallet).

Wallet
Connect above ↑
Sub-wallet
—
Same TEE sub-wallet as Swap. Yield Watch operates ON your sub-wallet's existing positions (deposit via /auto-defi-invest first if you haven't yet). Otto's worker runs hourly; auto-mode broadcasts only fire when a hysteresis-confirmed APY gap clears your signed thresholds.
Notify only. Otto Telegrams you when there's a better venue. You click the suggested two-call switch yourself. No on-chain delegation, no spending limits — just alerts.
You'll sign
Just a POST — no signature needed for Notify mode.
Pause / revoke an existing subscription
Auto mode requires a signed revoke (EIP-712); notify mode just sends a DELETE.

Free endpoints, right here.

All three below run against the live Otto X server — no API key, no payment, just click. Perfect for sanity-checking the service is alive before you wire up a paid call.

Look up a sub-wallet

Free · GET /sub-wallet/preview

Read-only DB lookup. Paste any EVM address to see whether Otto has already provisioned a TEE sub-wallet for it. Nothing is provisioned here — provisioning is tied to a real paid /auto-* call, not a button click.

Service health

Free · GET /health

One-click ping. Returns service name, chain, x402 network, and a timestamp. Useful as a canary during stress tests.

X Layer curated tokens

Free · GET /tokens

The on-the-house token registry Otto X uses for swap quoting on X Layer. Small, curated list with the native assets and stablecoins.

Full endpoint catalog

64 endpoints. One payment standard.

Every paid endpoint honors x402 Payment Required. Send a request with its inputs and without payment, receive a 402 with exact price + payment address. A missing or invalid input gets a 400 first, before any payment. Pay, retry, get data. No API keys.
