Grassets Tech is an independent Solana validator hosted in Prague, Czech Republic, carrying 178,833 SOL of activated stake (0.0116% of network stake) and a 99.31 Wiz Score as of epoch 971 (per Stakewiz).

Identity

Grassets Tech is an independent validator operation; its Stakewiz display name carries the suffix tags "Jito-BAM | IBRL" — referencing its participation in Jito-related MEV infrastructure ("BAM" = Block Assembly Marketplace, a Jito Labs product) and the "Increase Bandwidth, Reduce Latency" (IBRL) community grouping. The operator self-describes (Stakewiz description field) as "running Jito MEV + highly reliable and cutting edge hardware to maximize stakers rewards and support decentralization." The identity account is 9FXD1NXrK6xFU8i4gLAgjj2iMEWTqJhSuQN8tQuDfm2e; the vote account is 2g2QU1NDRax6i2mKzRwgRfdBFoDkMC6bj7Zp5Q3i8sCq.

Performance metrics

  • Wiz Score 99.31 — the highest score in this directory tier (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 99.71% with credit ratio 99.8% of cluster average (epoch 971, Stakewiz). The highest credit ratio in this directory tier and 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; Grassets Tech's last vote is current.

Grassets Tech's first epoch with stake was epoch 150, giving it 821 epochs of recorded mainnet history at epoch 971 — among the longest in the directory.

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 runs above the Stakewiz network average of ~4.4% (epoch 971, cluster_stats). With both commission components at 0%, the entire inflation and MEV payout the validator receives passes to stakers.

Infrastructure

  • ASN: AS201265 — Anafra A.S.
  • City and country: Prague, Czech Republic.
  • Software version: Agave 3.1.13 (version_valid: true at epoch 971, Stakewiz).

Anafra A.S. is a small Czech network operator; Prague is an uncommon Solana validator location, which is the structural contribution this validator makes to network geographic dispersion.

Decentralization signals

  • ASN concentration: 0.00% of network stake on AS201265 (Stakewiz asn_concentration).
  • City concentration: 0.27% of network stake in Prague (Stakewiz city_concentration).
  • ASN+city concentration: 0.00% (asncity_concentration).

All three figures sit well below SFDP's effective May 1, 2026 thresholds of ≤25% ASN concentration and ≤15% data-center concentration (per Solana Foundation delegation criteria). Among EU-hosted validators in this directory, Grassets Tech, Code-Breader, and polkachu.com each occupy a different small ASN — together they contribute to network ASN dispersion. The low single-ASN concentration figure is itself the decentralization signal.

MEV policy

Grassets Tech runs the Jito client (is_jito: true, Stakewiz, epoch 971) and participates in the Jito Block Engine MEV auction. The operator's Stakewiz name flags involvement in Jito's Block Assembly Marketplace product family. With Jito MEV commission at 0%, the validator retains no operator skim on Jito Block Engine tip distribution — stakers receive the full 0.13% Jito MEV APY component (epoch 971).

Delegation programs

  • SFDP status: Grassets Tech's metrics (skip rate 0.00%, base commission 0%, Jito MEV commission 0%, ASN concentration 0%) satisfy current SFDP performance and infrastructure thresholds; explicit enrollment status should be verified on the Solana Foundation delegation dashboard. Validators with multi-year mainnet histories and stake significantly above the 5,000 SOL retention threshold are generally outside the SFDP cycling window in any event.
  • Marinade SAM participation: Per-epoch auction state on marinade.finance.
  • Stake pool inclusion: Jito Stake Pool and SolBlaze inclusion vary per epoch — verify on the respective stake-pool dashboards.

Stake history

Grassets Tech holds 178,833 SOL active stake (0.0116% of network) at epoch 971 (Stakewiz). First epoch with stake was epoch 150; on-chain history is 821 epochs — placing Grassets Tech among the multi-year veterans in this directory rather than the newer cohort.
