Blockshard is a Switzerland-based, non-custodial Web3 staking and validator provider that ran a validator node on the Radix network. Headquartered in Zug (registry CHE-140.033.377) and formerly known as LetzBake, Blockshard is a founding member of the UnitedBloc DAO, an alliance of professional validator organisations.
Overview
Blockshard runs professional, enterprise-grade validator infrastructure across a range of proof-of-stake networks, prioritising high uptime, security, and a fully non-custodial model in which delegators retain ownership of their assets at all times. Through its membership in UnitedBloc, Blockshard also contributes to shared RPC endpoints, white-label nodes, and custom infrastructure for the wider validator community.
Radix validator
On Radix, Blockshard ran a validator node, until it unregistered in September 2026, that secured the network under its delegated proof-of-stake consensus. Because staking on Radix is non-custodial, holders keep custody of their tokens and delegate XRD to a validator directly from the Radix Wallet – there is no account to create and no deposit to Blockshard. Validators and their fees can be browsed on the Radix Dashboard, and stakers earn a share of network emissions proportional to the XRD delegated.
Supported networks
Alongside Radix (XRD), Blockshard's current network coverage includes:
- Tezos (XTZ)
- Ethereum (ETH)
- Moonbeam (GLMR) and Moonriver (MOVR)
- EigenLayer
- SSV Network (SSV)
- Avail (AVAIL)

Validator on the ledger
Blockshard's Radix node is validator_rdx1svudtxxkegaeg6ks0qgjujfp8g80de2f63ygvfqug6zv987e99jk3q, and on the ledger it does not carry Blockshard's name alone. Its name metadata reads Blockshard 🇨🇭|🇧🇬 RadixUID and its description metadata describes it as a collaboration between Blockshard and RadixUID. RadixUID is the Sofia-based Bulgarian community project already covered on this wiki, whose blog published “Stake to Blockshard” staking guides — the two flags in the node's name are Blockshard's Zug and RadixUID's Sofia. RadixUID's own validator is no longer registered and has since been renamed on-ledger, so this joint node was the part of that collaboration still running, until it unregistered as well (below).
Read at epoch 335,694 (state version 550,831,708, 17 August 2026), the validator was registered and sat inside the active set with 12,252,454.55 XRD of delegated stake — 66th of the 188 registered validators by stake, and 0.257% of the XRD staked to registered validators network-wide. The active set is the top 100 registered validators by stake each epoch, and only stake delegated inside it earns emissions, so delegators were being paid.
The node's fee is 1%, and the fee it charges matches the fee stored in its own substate with no pending fee-change request — worth checking rather than assuming, because the two diverge on a substantial minority of Radix validators. A further 313,400.04 XRD sits in the validator's pending withdraw vault (stake unbonding, in flight to unstake claims rather than lost), and 14,756.44 of the operator's own stake units are held in its locked owner-stake vault. Current figures for stake, fee and registration can be read at any time from the validator's page on the Radix Dashboard.
Unregistered after the restart
The node left the validator set two days after mainnet restarted on 11 September 2026. At 07:17:49 UTC on 13 September its owner badge was used to call unregister on the validator, in txid_rdx12qg9p4f…. Read at epoch 340,515 (state version 558,049,585, 15:06 UTC the same day), the validator reports registered: false and 0% uptime, while 13,999,244.68 XRD is still delegated to it – more than the 12.25 million it held in August. Only registered validators can enter the active set, so that stake earns no emissions until the node registers again or delegators move it. The fee stays at 1% and the node still accepts delegated stake, which means a new delegation would be accepted and would earn nothing.
It was one of three validators to unregister in the first two days after the restart, together holding about 38.2 million XRD; the other two are listed on Radix Ecosystem Operational Status.
