SEALCOIN AG develops a decentralized platform and peer-to-peer protocol for autonomous machine-to-machine transactions. Built on Hedera DLT and supported by smart contracts, PKI-based device identities, post-quantum cryptography, secure hardware, and non-custodial wallets, the platform enables devices and AI agents to negotiate, execute, and settle service-for-payment exchanges without human intermediaries. Use cases include peer-to-peer energy trading, decentralized data marketplaces, AI-agent transactions, smart-city infrastructure, industrial IoT, and satellite-enabled transactions. The platform is aimed at professional and individual users, enterprises, infrastructure operators, and public-sector organizations.
