onchain logic
Plasma smart contract
kernel
a Solidity contract deployed to Plasma Testnet via MetaMask private key, then verified on Plasmascan
how it drives the UI
a 'verified onchain' badge with the live contract address and a Plasmascan link
Four onchain primitives, demystified.
Every idea in this repo leans on one of four web3 primitives. Each one runs against Plasma Testnet (chain ID 9746, native token XPL, ~1s blocks, full EVM) so you can ship a verifiable demo with zero hosting and free faucet gas.
The four secrets
Add these in your Lovable project (Settings → Secrets) before pasting any mega-prompt:
- METAMASK_PRIVATE_KEYExported from MetaMask. Fund on Plasma Testnet via openfaucet.org (free XPL).open ↗
- PRIVY_APP_IDGoogle sign-in and an embedded wallet auto-provisioned on Plasma.open ↗
- PINATA_JWTPin to IPFS.open ↗
- PLASMA_RPC_URLOptional. Defaults to https://testnet-rpc.plasma.to (public, rate-limited).

decentralized storage
IPFS via Pinata
kernel
a Pinata JWT upload that pins images / JSON / manifests to IPFS and returns a permanent CID
how it drives the UI
a 'pinned to IPFS' chip with the CID and an ipfs.io gateway preview
wallet UX
Privy social sign-in
kernel
Privy embedded wallet bootstrapped with PRIVY_APP_ID — Google sign-in creates an EOA on Plasma Testnet; users top up XPL from openfaucet.org
how it drives the UI
a one-click 'Sign in with Google' that drops the user straight into the app with an onchain identity on Plasma
onchain authorship
NFT provenance mint
kernel
an ERC-721 contract on Plasma Testnet that mints a creator-owned token pointing at an IPFS CID, verified on Plasmascan
how it drives the UI
a 'mint to claim authorship' button that returns the tokenId, owner address, and Plasmascan link
