I need to call Lit Protocol from the Polygon chain purely for data encryption and decryption, while signing every interaction with an ordinary Ether wallet—no dedicated Lit wallet should ever be required. Here is what I have in mind: • A minimal smart-contract setup on Polygon that can trigger Lit’s JS SDK for encrypting and later decrypting data. • Front-end or script examples that let me sign those calls with any standard EVM wallet (MetaMask, Trust Wallet, etc.) so long as the user never has to create or fund a Lit wallet. • Clear, step-by-step deployment notes so I can replicate the flow in testnet and mainnet, plus concise code comments referencing the Lit nodes, auth sig generation, and the specific Polygon RPC endpoints used. Acceptance criteria 1. I can encrypt an arbitrary string from the UI or script, store the ciphertext on-chain or off-chain, and later decrypt it back using the same wallet signature. 2. Transactions confirm on Polygon without re-prompting for a Lit login. 3. A short readme walks through setup, environment variables, and contract verification. I’m open to recommendations on tooling (Hardhat, Foundry, [login to view URL], wagmi, etc.) as long as the final workflow stays lightweight and developer-friendly.

Hello, your "Polygon Lit Encryption Integration" project is right in my wheelhouse. I develop modern JavaScript apps end to end — React/Vue/Next on the front and Node/Express on the back, in TypeScript where it helps. Working with javascript, cryptography, ethereum, smart contracts, hardhat, I focus on responsive, fast UIs, clean component structure, and reliable APIs — no page-builder shortcuts. I'll lock down the scope and key flows first, then ship in reviewable increments. Let's hop on a quick chat to align on your requirements? ⭐ 5.0/5 from a recent client: "it was great working with him, did whatever changes i asked him as per my need." Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

Hi, I can build the Polygon-to-Lit integration you described—encryption and decryption triggered from a minimal on-chain contract, with every interaction signed by a standard EVM wallet and no Lit wallet needed. I’ll deliver a working script and a lightweight front-end example. Two concrete steps I’ll include: first, generating an auth sig from your MetaMask or Trust Wallet and using it to obtain a session signature from the Lit nodes; second, encrypting a test string via the Lit JS SDK, storing the ciphertext, then decrypting it back with the same wallet signature to confirm the round-trip works on Polygon testnet. One question: do you prefer the ciphertext stored on-chain in the contract, or off-chain (e.g., IPFS or a simple JSON file) with just a reference kept on-chain? I’ll provide clear deployment notes and commented code for both testnet and mainnet. I can complete this in around 10 days for INR 1500.
