Text Swap

Problem

Buying memecoins or swapping assets directly from chat applications (Twitter, Discord, etc.) is cumbersome and error-prone.

Solution

Leverage ERC-7710 & ERC-7715 to delegate spending permissions to an on-chain Delegate Locker contract.
The contract may spend a user's funds only when presented with a valid zkTLS proof that the user actually posted the required chat message.

The current demo:

• Network: Sepolia
• Flow: Buy any token with ETH through CoW Swap

End-to-End Flow

1. User opens the site; prompted to install MetaMask Flask if needed.
2. User connects to Twitter with OAuth.
3. The UI shows the Delegator/Gator smart-account address — user funds it with ETH.
4. A UserOperation creates an ERC-7715 delegation that allows Text Swap's Delegate/session account to spend up to a defined limit.
5. A background service watches Twitter for messages of the form:

   @locker_money buy token: 0xTokenAddress amount: 1
   

6. When a matching tweet is found, Reclaim Protocol is used to generate a zkTLS proof of the tweet's existence.
7. The proof is submitted (via another UserOperation) to the Delegate/session account which, after verification, swaps the user's ETH for the requested token on CoW Swap (Sepolia).
8. The purchased tokens are transferred back to the user's Delegator/Gator account.

Roadmap

• OAuth flow for Twitter and Discord.
• Integrate zkTLS prover service.
• Support arbitrary ERC-20 amounts & decimals.
• Extend beyond ETH→Token swaps.
• Production deploy & audits.

Developer Quick-Start (Sepolia)

pnpm i
pnpm dev

1. Set .env.local with:

   NEXT_PUBLIC_BASE_URL=https://<your-ngrok>.ngrok.app
   NEXT_PUBLIC_TWITTER_CLIENT_ID=...
   TWITTER_CLIENT_SECRET=...
   

2. Run an ngrok tunnel to expose port 3000.
3. Configure the same callback URL in the Twitter Developer Portal.
