onchain logic
BNB smart contract
kernel
a Solidity contract deployed to BNB Smart Chain Testnet via MetaMask private key, then verified on BscScan
how it drives the UI
a 'verified onchain' badge with the live contract address and a BscScan link
Four onchain primitives, demystified.
Every idea in this repo leans on one of four web3 primitives. Each one runs against BNB Smart Chain Testnet (a free, real testnet) so you can ship a verifiable demo with zero hosting and zero gas spent by your users.
The five secrets

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 plus an auto-provisioned wallet on BNB Smart Chain Testnet
how it drives the UI
a one-click 'Sign in with Google' that drops the user straight into the app with an onchain identity
onchain authorship
NFT provenance mint
kernel
a BEP-721 (ERC-721) contract on BNB Smart Chain Testnet that mints a creator-owned token pointing at an IPFS CID, verified on BscScan
how it drives the UI
a 'mint to claim authorship' button that returns the tokenId, owner address, and BscScan link
