Kolibrio is an independent Solana validator operated by Kolibrio, a web3 infrastructure company focused on transaction execution and order-flow services for wallets and dApps; the validator carries 243,929 SOL of activated stake (0.0158% of network stake) and a 98.66 Wiz Score as of epoch 971 (per Stakewiz).

Identity

Kolibrio operates this validator as part of its broader Solana infrastructure stack. The operator self-describes (Stakewiz description field) as "a web3 infra company focused on improving transaction execution" that helps "wallets and dApps unlock the maximum value from their orderflow on Solana." The validator's identity account is KoLibrJsbABbtmtFPc7nPvDxT81rc4UPM7mY9xSLjpo; the vote account is 34mSDco9FM8599y4QF1GJvyWUrPixeT3zRNZAvzNXF6x. The operating jurisdiction is not publicly disclosed by the operator. The node itself is hosted in the Netherlands (see Infrastructure below).

Performance metrics

  • Wiz Score 98.66 (epoch 971, per Stakewiz).
  • 30-day trailing skip rate 0.00% vs. 0.14% network median at epoch 971 (Stakewiz wiz_skip_rate field and cluster_stats).
  • Vote success 99.59% with credit ratio 99.7% of cluster average (epoch 971, Stakewiz). Both figures sit above the SFDP per-epoch vote-credit threshold of 97% of cluster average.
  • Uptime 100% at the current Stakewiz snapshot.
  • Delinquent: no at epoch 971 (Stakewiz delinquent field). A delinquent validator is one whose last vote lags the ledger tip by more than ~128 slots; Kolibrio's last vote is current.

Kolibrio's first epoch with stake was epoch 794, giving it 177 epochs of recorded mainnet history at epoch 971 — roughly 12 months. The 30-day skip-rate window therefore covers a meaningful share of the validator's total operating period, and longer-horizon comparisons against multi-year operators in this directory should be made with that caveat in mind. Newer validators have less data to assess.

Economics

  • Base commission 0% (epoch 971, Stakewiz). Sits at the SFDP base-commission cap of ≤5%.
  • Jito MEV commission 0% (jito_commission_bps: 0, epoch 971). Below the SFDP Jito MEV cap of ≤10%.
  • Total APY 6.02% including Jito MEV rewards (epoch 971, per Stakewiz total_apy). Components: 5.89% base staking APY and 0.13% Jito MEV APY.

Total APY sits above the Stakewiz network average of ~4.4% (epoch 971, cluster_stats), which reflects Kolibrio's 0% base commission — stakers retain the entire inflation payout the validator receives.

Infrastructure

  • ASN: AS58061 — Iroko Networks Corporation.
  • Location: Meppel, Netherlands.
  • Software version: Agave 3.1.13 (version_valid: true at epoch 971, Stakewiz).

The hosting provider is a small Dutch network operator outside the major Solana ASN clusters; Iroko Networks does not appear in the top-concentration ASNs flagged by SFDP's May 1, 2026 infrastructure thresholds.

Decentralization signals

  • ASN concentration: 0.06% of network stake on AS58061 (Stakewiz asn_concentration).
  • City concentration: 0.01% of network stake in Meppel (Stakewiz city_concentration).
  • ASN+city concentration: 0.01% (asncity_concentration).

Both figures sit well below SFDP's effective May 1, 2026 thresholds: ≤25% ASN concentration and ≤15% data-center concentration (per Solana Foundation delegation criteria). Kolibrio's hosting choice contributes positively to network ASN dispersion.

MEV policy

Kolibrio runs the Jito client (is_jito: true, Stakewiz, epoch 971) — the MEV-aware Agave-derived validator software fork. The 0% Jito MEV commission means all Jito Block Engine tip distribution captured by Kolibrio passes through to stakers, with no operator skim. Stakers receive the full 0.13% Jito APY component on top of the 5.89% base staking APY.

Delegation programs

  • SFDP status: Kolibrio's metrics (skip rate 0.00%, base commission 0%, Jito MEV commission 0%, ASN concentration 0.06%) satisfy current SFDP performance and infrastructure thresholds; explicit enrollment status should be verified against the Solana Foundation delegation dashboard.
  • Marinade SAM participation: Public bid status is published per epoch on Marinade Finance; consult marinade.finance for the current epoch's auction state.
  • Stake pool inclusion: Observable Jito Stake Pool and SolBlaze inclusion changes per epoch — verify against the respective stake-pool dashboards.

Stake history

Kolibrio holds 243,929 SOL active stake (0.0158% of network) at epoch 971 (Stakewiz). The validator's first epoch with stake was epoch 794, putting its on-chain history at 177 epochs — substantially shorter than several multi-year operators elsewhere in this directory. For staking decisions where stake-history stability is part of the evaluation, Kolibrio's record covers fewer epochs of mainnet performance than veteran validators.
