Validators

Polygon PoS has 100+ active validators. POLTRACK tracks all of them with snapshots, scoring, and analytics.

POLTRACK Score

Each validator receives a composite score (0–100) based on:

Score badges:

• 90–100 Excellent
• 75–89 Good
• 50–74 Fair
• 25–49 Poor
• 0–24 Critical

Scores update every 4 hours. See all scores at /validators.

Commission

Validators charge a commission on staking rewards. The rate is set on-chain and can change.

• 0% = delegator keeps 100% of rewards
• 5% = validator takes 5%, delegator gets 95%
• 100% = delegator gets nothing

POLTRACK tracks commission changes and alerts you when your validator changes rates.

Commission cost calculation

Annual commission cost = your_stake × commission_rate × network_apy

Example: 100,000 POL staked on a 5% commission validator at 5.5% APY = 275 POL/year (~$26 at $0.096).

Performance

Performance is measured by checkpoint participation on Ethereum L1.

• performance_index: % of checkpoints signed (0–100)
• Validators must sign checkpoints to earn rewards
• Missing checkpoints reduces rewards for all delegators

POLTRACK shows:

• Current performance index
• Missed checkpoints (total and recent streak)
• Jail status and deactivation epoch

PIP-65 & PIP-85

PIP-65 (Priority Fee Sharing)

Validators receive a share of priority fees from Polygon PoS transactions. POLTRACK tracks PIP-65 batch payments and estimates per-validator income.

PIP-85 (Staker Fee Share)

Under PIP-85, stakers receive 37% of priority fees (50% of the 74% PIP-65 pool). POLTRACK estimates this as fee_income × 0.37 per validator.

Stake flows

Daily validator snapshots track delegated_wei changes. POLTRACK computes:

• Net inflows and outflows per validator over rolling periods
• Top movers (largest gains and losses)
• Commission changes and status changes trigger personal alerts via Telegram
