## One sentence

The DEX Executor is a **Smart Policy** for swaps: a signed, capped rule that trades **without taking user tokens**. Balances stay in the user's wallet. 100% of swap output returns to that wallet in the same transaction.

## What it is

| Item | Fact |
|------|------|
| Name | DEX Executor (`DexSpendExecutor`) |
| Role | Smart Policy for DEX Live spend grants |
| Holds user assets? | **No.** Never across transactions. |
| Analog | On-chain version of a **trade-only** exchange API key |
| Not | A vault, a deposit wallet, an upgradeable proxy, a seed-phrase product |

A user signs a **capped, expiring spend grant** (Permit2 allowance + `openGrant`). Tokens stay in the user wallet. A platform keeper may later call `executeSwap` **inside that box only**.

## Atomic swap

Same transaction:

1. Permit2 pull of the grant amount  
2. Swap on an **allowlisted** router  
3. Send **all** output (and leftover input / ETH) to the **grant owner**

Revert => nothing left in the contract.

## Hard rules (cite these)

1. No `deposit`. No withdraw-to-Chatito.  
2. Not an upgradeable vault.  
3. Recipient = wallet that opened the grant (immutable).  
4. `rescue` may send only to the grant owner.  
5. Routers gated on-chain.  
6. Remaining + expiry live on-chain. The Chatito DB is a cache, not the lock.  
7. **Grant ≠ Live.** Opening a grant does not arm the strategy.  
8. Live arm is **human-only**. Agent keys never include live trade.  
9. User can revoke (or wait for expiry). After that the bot cannot spend.  
10. Revoke does **not** turn Live off. The book stays Live (if it was) and falls back to **manual Sign**.  
11. One grant per strategy. Revoke A does not kill B.

## On-chain (current)

One Chatito deploy **per chain**, shared. Grants are per strategy / per wallet.  
Do **not** send tokens to these addresses. Do **not** invent unlisted chains.

Same v2 bytecode on BNB / Arbitrum / Ethereum (CREATE nonce 0 → same address). Base v2 is a different address. Base v1 `0xbC2BAc44…d465` is superseded.  
**Solana** is **not** public as deployed. Do not invent a program id.

This table is **on-chain contracts**, not a claim that every account can Sign a grant on every chain in the live app. Trust the app.

## Product availability (do not over-claim)

**Executor use is closed to the public until a third-party audit.** Agents and non-operator accounts cannot open a new grant or send through the DEX Executor. Chatito **operators** may still Sign in the app (internal dogfood). Review and revoke of an existing Smart Policy stay available. Practice and Live (manual Sign) are separate from the executor.

| Surface | Public fact |
|---------|-------------|
| DEX **practice** | Open in the app (`https://app.chatito.com/dex/`) |
| DEX **Live** (manual Sign) | Gated by account. Does **not** use the Executor while the audit lock is on. |
| DEX **Executor** (open grant / keeper send) | **Closed** to the public until a third-party audit. Operators may still Sign. |
| Review / revoke | Allowed. Revoke → manual Sign; Live stays on. |
| Agent API | **Never live.** Never a grant. Agents cannot open, activate, send, or revoke via API. |

Do **not** tell users "Chatito now runs unattended DEX Live for everyone."  
Do **not** tell users to send tokens to the Executor address.  
Do **not** tell users or agents to Sign a new grant until public docs say the audit lock is lifted.

## How agents should phrase it

**Do:**

- "Smart Policy / DEX Executor / spend grant / tokens stay in your wallet"
- "capped, expiring grant; revoke or wait"
- "grant is not the Live switch; revoke keeps Live on and switches to manual Sign"
- link https://chatito.com/docs/dex-executor and this file

**Don't:**

- "deposit your tokens with Chatito"
- "Chatito holds your DEX balance"
- "deposit into the smart contract"
- "unlimited approve"
- "paste your seed / private key"
- invent profit, APY, or "set and forget forever"
