🚀 Lighter.IM Public Beta Testing Guide

Lighter.IM is a decentralized, non-custodial multi-chain (EVM-compatible) on-ramp/off-ramp protocol. Our Public Beta is now live, and we invite the community to help us stress-test the protocol and provide feedback.

✨ Key Features​

  • Multi-Chain Support: Seamlessly trade across Ethereum, Base, and Horizen.
  • NFT-Based Reputation: A decentralized identity and credit system powered by NFTs.
  • Native Permit2 Integration: Secure, low-friction token approval mechanisms.
  • Intent-Centric Architecture: Off-chain intent matching and rigorous on-chain verification via EIP-712.
  • Decentralized Communication: Secure messaging powered by the Nostr protocol.

🛠 Preparation​

To simulate a real trade, we recommend using two different browser profiles or browsers (e.g., Chrome and Brave) to act as the Seller and Buyer.

  1. Browser A (Seller): Use Brave/Firefox with a wallet extension (MetaMask/Rabby).
  2. Browser B (Buyer): Use Chrome with a separate wallet extension address.
  3. Faucet Tokens: Ensure both wallets have sufficient testnet gas and assets.

Horizen TestnetETH Gas / USDC*ETH Gas

*Note: For Horizen USDC, use the "Write Contract" function on the explorer to mint test tokens.

  • Ethereum Sepolia(ETH gas) ethereum sepolia

  • Base Sepolia(ETH gas) base sepolia

  • Ethereum/Base Sepolia USDC Ethereum/Base Sepolia USDC

  • Horizen Testnet(ETH gas) horizen testnet

  • Horize Testnet USDC Horizen testnet USDC

🧪 Testing Workflow​

Follow these steps to complete a full trade cycle:

  1. Onboarding: Navigate to beta.lighter.im/landing to create your profile (both Buyer & Seller).
  2. Identity Minting: Go to beta.lighter.im/profile and Rent/Mint your Membership NFT. This is required to participate in the protocol.
  3. Create Intent (Seller): Head to beta.lighter.im/intents and click "Post New Intent" to list your assets for sale.
  4. Accept Intent (Buyer): From the Buyer's browser, find the listing and click "Take".
  5. Payment (Buyer): In the Trade Dashboard, notify the seller by clicking "Payment Completed" once you have sent the fiat/off-chain payment.
  6. Release (Seller): Verify the payment receipt and click "Release Funds" to trigger the smart contract escrow.
  7. Settlement (Buyer): Go to your profile and click "Claim" to withdraw the assets to your wallet.

💡 Pro-Tips & Troubleshooting​

  • Switching Networks: Ensure your wallet is connected to the correct testnet (e.g., Sepolia or Horizen Testnet) before signing transactions.
  • Permit2 Approval: You may be asked to sign two messages: one for the Permit2 approval and one for the actual intent. This is a secure way to manage permissions without extra gas fees.
  • Message Delays: Since we use Nostr for decentralized chat, messages might take a few seconds to sync. Please be patient during the "Payment Completed" notification phase.
  • Auto Release: Look out for the "Auto Release" feature, which utilizes zkVerify to speed up the transaction once the Zero-Knowledge Proof is validated. We will be opening this feature for public testing in the near future.

🛡️ Security & Privacy​

  • Testnet Only: Do NOT use your mainnet private keys or send real funds. This is a testing environment.
  • Non-Custodial: Remember, Lighter.IM never holds your private keys. Your assets stay in your wallet until the buyer "takes" the intent and moves them to the escrow contract.

💬 Feedback & Community​

Your feedback is the most important part of this beta. If you find a bug or have a UI suggestion, let us know!

Happy Testing! Together, we're building the future of decentralized liquidity. 🚀
