Burner
Project Links
Description
Burner is a compact, secure computer designed to protect digital assets and identities. It operates with secure chips similar to those in hardware wallets but is user-friendly and open source. Burner can be used with any dapp via Wallet Connect and is pin-code protected. It simplifies gifting crypto with its USD II stablecoin and includes features for power users like NFT storage and multisig linking.Kong

Description
KONG Land is a metanation that interacts with the real world through diplomatic relations, economic covenants, state functions, and social services. It embeds HaLo chips in merchandise, art, and collectibles to link them to NFTs, tokens, and experiences.LibHaLo
Project Links
Description
LibHaLo is an npm/Yarn-installable library for interacting with HaLo NFC tags in web browsers, React Native/Expo applications, and desktop PC/SC applications. It provides APIs to scan tags, execute HaLo commands, and return results, supporting signing, key generation and management, NDEF configuration and reading, and firmware-version checks. The project also includes HaLo Bridge for connecting USB NFC readers to web applications and HaLo Gateway for using a smartphone as a remote NFC reader.Category: Developer Tooling
HaLo
Project Links
Description
Released in 2022, HaLo (“Hardware Locked Smart Contracts”) chips generate non-extractable secp256k1 ECDSA keypairs during manufacture. A holder can instruct a chip to generate signatures for on-chain or off-chain authentication, asset transfers, address whitelisting, and related uses; signatures support standards including EIP-191 and EIP-712. HaLo chips provide NFC/NDEF, browser-based Credentials API, and proprietary APDU interfaces.Category: Hardware Wallet
Ethereum Reality Service
Project Links
Description
Ethereum Reality Service (ERS) is a smart-contract protocol for decentralized authentication, claims, and redirection for secure chips. It supports tracking chip provenance across manufacturer enrollment, brand or creator distribution, and end-user authentication. ERS also enables brands and creators to attach chip-linked experiences that end users access in a decentralized manner, reducing reliance on centralized authentication and experience-delivery services.Category: Decentralised Identity
