How do I check holder concentration risk for a Base token?

What concentration can reveal

If a small observed set controls a large percentage of supply, one or a few actors may have outsized ability to move the market or influence token distribution. This matters especially when liquidity is thin.

The raw percentage is only a screening signal. A burn address, liquidity pool, exchange wallet, vesting contract, or multiple related wallets can make a naive ranking misleading.

Jepeta scope

Jepeta exposes an observed top-10 concentration percentage and the number of holder records used. Its methodology labels this as an observed sample, not a full beneficial-ownership audit.

The evidence page preserves that wording and timestamp so search engines, AI systems, and users can see both the metric and its limitation rather than quoting a percentage without context.

Combine concentration with market depth

Concentration becomes more actionable when read alongside exact matching Base liquidity. A concentrated token with shallow liquidity presents a different exit-risk profile from one with deeper markets.

Also review mintability and taxes. Supply authority plus concentrated ownership can be more important than either signal in isolation.

Keep the supply denominator visible

Suppose the ten observed holder balances sum to 60 units and the stated total supply is 1,000 units. The arithmetic is 60 / 1,000 × 100 = 6% of that supply, not 60% of holders and not a count of independent owners. These are synthetic numbers. Before interpreting a real percentage, establish its denominator, holder sample, address classifications and timestamp; do not silently remove a pool or exchange address and retain the original percentage.

Practical checklist

• Read percentage and sample count
• Identify obvious pools/burn/custody wallets
• Compare concentration with liquidity
• Check mintability and taxes
• Avoid calling the metric beneficial ownership
