01node is a Bucharest-based blockchain infrastructure provider focused on sovereign, bare-metal operations. Founded in 2019, the company says it runs its own hardware and network rather than relying on cloud services or colocation. Its infrastructure includes AMD EPYC processors, enterprise NVMe storage, hardware security modules, and network operations under AS41536, with direct peering and global anycast routing. 01node reports 99.99% uptime, more than $540 million in assets managed, and over 50,000 delegators across 40-plus networks.

Its services cover the full lifecycle of blockchain infrastructure. These include Proof-of-Stake validator operations, low-latency RPC and API endpoints, automated ledger snapshots, seed and sentry node setups, and whitelabel infrastructure for organizations launching validators. The company also provides chain-launch support, including genesis assistance, parameter tuning, and infrastructure bootstrapping. Security measures include HSM-backed key custody, isolated environments, failover systems, monitoring, and double-sign protection. 01node lists support for networks such as Ethereum, Solana, Cosmos, Celestia, Sui, and Aptos, and cites ISO 27001 and ISO 9001 credentials.
