toluTag

toluTag connects the physical world to the blockchain. Each toluTag is an NFC tag built around an NXP SE05x secure element that holds its own secp256k1 key, so a real object can carry a blockchain identity you can prove on-chain. With toluTag you provision that key, read the tag's public identity, and sign cryptographic proofs that smart contracts on Ethereum, Base, and other EVM chains can verify. It is the bridge between a physical item and Web3. Built for makers, brands, and developers bringing real-world objects on-chain. WHAT YOU CAN DO • Create keys: generate a secp256k1 key pair on a tag, with an optional PIN, and view its Ethereum address. Every tag becomes its own on-chain identity. • Sign a message: produce an EIP-191 signature (r, s, v) with the tag's key, so a contract or backend can verify the tag signed it. • Sign typed data: sign any EIP-712 (eth_signTypedData_v4)…
