What happened with the InfStones security issue?

In 2023 external researchers found a platform vulnerability that could have exposed customer keys. It was patched with no reported exploitation, but it was disclosed by outsiders rather than by the company.

How many networks does InfStones support?

Dozens, including many that larger operators do not cover, with both staking and node API services.

What does InfStones charge?

Typically 8–10% of staking rewards, with infrastructure and API services priced separately.

Is InfStones custodial?

It depends on the network and product; both custodial and non-custodial arrangements exist, so confirm which applies before staking.

InfStones Review 2026: Wide Coverage, Late Disclosure

Name: InfStones review
Item: InfStones
Rating: 7.7
Author: OBOL

InfStones serves developers as much as stakers: node APIs, RPC endpoints and validator operation across dozens of networks, with pricing below the institutional norm and tooling that is genuinely good for building on.

The 2023 vulnerability

External researchers identified a platform vulnerability that, if exploited, could have exposed customer keys held by the service. It was remediated and no exploitation was reported. What the incident says about the operator is not that a vulnerability existed — they always do — but that it was found and reported by outsiders rather than surfaced by internal review or a bug bounty. That gap in security process is why disclosure and operational transparency score lower here than at the top-tier operators.

Performance and coverage

Above-average uptime across the networks it supports, with a very wide list including many chains the major operators ignore. Both custodial and non-custodial options exist depending on the network.

Pricing

Typically 8–10% of rewards, with infrastructure services priced separately. Competitive for the coverage on offer.

Who should use it

Developers needing node infrastructure alongside staking, and delegators on networks where better-documented operators are absent. For core allocations on major chains, operators with stronger disclosure practices are the safer choice.
