RadUp.io is a validator on the Radix network. Its site describes a high-performance node serving the Radix community, and says the Radix team chose RadUp to run a validator on the betanet before mainnet, after which it kept a node on Stokenet, Radix’s public test network.
Website
radup.io serves a one-page site again. This page recorded Cloudflare errors there from July to August 2026, 522 and then 523, both meaning Cloudflare could not reach the server behind the domain; on 15 September 2026 it answered with the site. www.radup.io, the address the validator’s on-ledger metadata links, still returned 522.
The site gives the Babylon validator address and links the node’s Radix Dashboard page. Its text is the Olympia-era copy: six promises, one of them “No fee increases for the duration of Olympia”, and an answer to what RadUp charges that points readers to the dashboard. Olympia ended when Radix moved to Babylon in July 2023, and the fee the node charges today is set out under On-ledger status below.
Staking with RadUp
XRD is staked to RadUp from the Radix Wallet or from its Radix Dashboard page, using the address validator_rdx1s0drhvkx30k62zu0usnzxzwuh0qcsqwlc2n2kfyexlyghqpctuy2fx. The archived Olympia-era site gave rv1q2twz…250d832l, which does not resolve on Babylon. The current site asks delegators to follow what it calls the Radix team’s 5-by-5 rule: spread stake across five validators that each hold less than 5% of the total, and stake elsewhere if RadUp passes 5%.
History
On Olympia, RadUp’s fee page set a fixed fee of 1.95%, so that stakers kept more than 98% of their rewards, and promised no fee increase for the rest of that network. The old site told stakers to use the Radix desktop wallet, which Babylon replaced with the Radix Wallet and liquid stake units.
On-ledger status (September 2026)
Read from the Radix Gateway at epoch 340,947 on 15 September 2026, the RadUp.io validator is registered and accepts delegated stake. It holds the 42nd-largest stake of the 186 registered validators, down from 36.3m XRD and 36th place on 6 August. From 16 August to 15 September it missed 16 of its 60,714 proposals, and none since mainnet restarted on 11 September after the Hyperlane asset drain halt.
The node charges 15%, not 1.95%. Its stored fee factor is still 0.0195, but a fee change to 15% took effect at epoch 312,126 on 27 May 2026, and the effective rate is the one applied to rewards. A delegator going by the old fee page, or by the new site’s promise against fee increases, would expect about an eighth of what the node takes. Its on-ledger info_url is https://www.radup.io. Stake units are resource_rdx1t47…xqv3mxu and unstake claims resource_rdx1nfp…l6tlhqy.
