mwbpNFTechnology/toluTag
Open-source passive NFC tag signing ECDSA, bridging the physical world to on-chain validation.
About the project
Open tooling for provisioning and using NXP SE05x secure elements as NFC-readable Ethereum signers: the key is generated on-chip and never leaves it, and signatures verify directly against the chip's address with no server in the trust path.
Useful for
- Provision a batch of SE05x NFC tags via the Java CLI to bind physical objects to Ethereum addresses
- Sign an EIP-191 or EIP-712 message from a phone with the iOS app by tapping the tag to the reader
- Verify a tag's signature in a smart contract to unlock a product's digital twin
