Upnode | 0% Fee Staking Provider

ZERO FEE until January 2028. We reimburse the fee every month. Professionally managed, institutional-grade blockchain infrastructure. Beyond offering top-tier validator and staking services, we deploy and monitor your web3 API seamlessly on your servers, bringing true decentralization to web3 apps.

We are a team of experienced node operators and blockchain developers with over 30 years of combined experience in Web 2.0 and Web 3.0 deployments. We have a track record in the development of and contributions to multiple tools to support our node operations. We were awarded the Optimism Grant to build Upnode Deploy, an all-in-one API Deployment Tool for web3 developers.

Upnode employs an Active-Standby validator system across multiple regions for maximum availability, protected by a VPN network managed by a Fortigate firewall. Servers maintain advanced firewalls with limited port exposure to prevent unattended access. Private keys are stored securely using YubiHSM2; if not supported, we use YubiKey for the SSH key of the validator node. We employ two different OS for each of our datacenters, one relies on Proxmox VMs for node isolation, while the other relies on Ubuntu bare metal for optimal performance, which is our primary active node. We have an intensive monitoring and alerting stack with Tenderduty, Grafana, Loki, Prometheus Alertmanager, and more with alerts directed to our engineer 24/7 through PagerDuty for incident management.

We always vote 'NO' on spam proposals. We generally vote 'YES' on protocol upgrade proposals from official sources. For other types of proposals, we review evidence of discussions from the related governance forums before making our decision.
