Delegate OSMO to a bare-metal validator running on owned hardware in two Tier III datacenters since 2019. The address below is on-chain verifiable on the listed explorer.
osmovaloper17mggn4znyeyg25wd7498qxl7r2jhgue8td054xOsmosis (OSMO) is the largest DEX in the Cosmos ecosystem and the routing hub for inter-chain liquidity via IBC. Mainnet launched in June 2021. The chain hosts hundreds of liquidity pools, has integrated with Revolut for fiat ramps, and serves as the de-facto trading venue for nearly every Cosmos-native asset.
OSMO holders stake their tokens with validators to secure the chain and earn inflation rewards. The active set is fixed at the top 150 validators by stake. Osmosis governance has been particularly active — a long history of community proposals around tokenomics, fee policy, and protocol upgrades.
On March 6, 2025, our original Osmosis validator was tombstoned after a Horcrux v3.3.1 race condition produced two near-simultaneous signatures for block 30968345 (1.5 ms apart). The bug was disclosed by Strangelove Ventures in GHSA-6wxf-7784-62fp and patched in v3.3.2 within 28 hours. We reimbursed all 4,650 affected delegators in full from our operational reserve and launched the current validator. Full post-mortem at /blog/one-point-five-milliseconds-osmosis-horcrux-incident.
01node has run Osmosis since the 2021 mainnet launch. The March 2025 Horcrux incident (vendor bug, fully reimbursed) is documented at /security#disclosed-incidents — zero net delegator loss.
Same threshold-signing architecture as Cosmos Hub, on the patched Horcrux version that eliminates the race condition exposed in March 2025.
We vote on every Osmosis proposal with published rationale. Verifiable on Mintscan governance.
Competitive commission for the top-tier operator group. Live rate always shown in your wallet before signing.
Osmosis block times reward operators with low-latency peering. Our 20 Gbps+ AS41536 transit is built for this.
Osmosis is supported natively in all major Cosmos wallets.
Deep-links to Keplr with our current Osmosis validator pre-selected on osmosis-1 (the old validator was tombstoned in March 2025; this is the new address).
Leave a small buffer for transaction fees and future actions. The unbonding period is 14 days, faster than Cosmos Hub.
Osmosis distributes rewards continuously. Claim or restake at any point — there is no cliff.
14-day unbonding window during which OSMO earns no rewards and cannot be moved.
Standard Cosmos slashing model — 5% for double-sign, smaller for downtime. One disclosed slashing incident on Osmosis (March 2025, Horcrux v3.3.1 vendor bug), fully reimbursed. All 4,650 affected delegators were made whole from our operational reserve.
If we drop below the top 150, rewards stop until we re-enter. Continuous active-set presence since the new validator launched in March 2025.
14 days. Faster than Cosmos Hub’s 21 days. During this window OSMO earns no rewards and cannot be transferred.
On March 6, 2025, our original Osmosis validator was tombstoned after a race condition in Horcrux v3.3.1 produced two signatures 1.5 ms apart for the same block. Strangelove Ventures (Horcrux maintainer) disclosed the bug in GHSA-6wxf-7784-62fp and patched it in v3.3.2. We reimbursed all 4,650 affected delegators in full from our operational reserve. The current validator on this page is the replacement validator launched after the incident. Full post-mortem: /blog/one-point-five-milliseconds-osmosis-horcrux-incident.
Yes. 4,650 delegator addresses received refunds totaling 75,305,896,736 uOSMO (~75,306 OSMO) — the exact amount slashed by the protocol. Refunds were issued from 01node’s operational reserve as direct on-chain transfers.
Osmosis has reduced its inflation target over time as the chain matured and fee revenue from DEX activity grew. The current APR reflects that lower inflation; chains with higher inflation (Babylon, Lava) compensate validators differently.
OSMO stakers vote on proposals proportional to their stake. Validators vote on behalf of their delegators by default; delegators can override with their own vote at any time. We publish rationale for every vote.
5% — verifiable on Mintscan and in your wallet before signing.
On March 6, 2025, our Osmosis validator double-signed at block 30968345. Two signatures, 1.5 milliseconds apart, exposed a Horcrux race condition that had been latent in production for 20 months. We were one of hundreds of operators running the affected version — and the only one fast enough to hit the bug. This is what happened, why it happened to us specifically, and how we reimbursed every affected delegator in full.
12 MIN READ→EngineeringFive years ago a validator was a server. Today it is a cluster of signers, and the math is the entire reason solo operators still slash themselves. A focused walk-through of the 2/3 signing architecture, the slashing-protection check that runs before every block, and the key-sharding property that makes a single compromised node useless.
7 MIN READ→EngineeringIn June 2019 we published our validator architecture on Medium — YubiHSM dual-DC, VPN-only access, sentries per network. Seven years and forty mainnets later, here is what we kept, what we changed, and what we would do differently if we started today.
