toluTag

toluTag is an open-source project providing tooling and apps to provision, inspect, and use passive NFC tags containing NXP SE05x secure elements for Ethereum-compatible cryptographic signing directly on the tag, bridging the physical world to on-chain validation without centralized servers. It supports iOS and Java CLI clients for managing key pairs, signing messages, and interacting with the tags, alongside hardware designs for custom tag form factors like cards, stickers, and textiles.
