Chainlink Holder Analysis Using SQL Parameters | Crypto SQL Advanced #8
In this video, we go beyond simple token balances and explore who actually controls the LINK supply.
Using SQL on Dune, we reconstruct wallet balances, analyze the largest Chainlink holders, and visualize how the token supply is distributed across wallets.
We also make the query reusable by introducing SQL parameters, allowing the same logic to work for any ERC-20 token.
This is where on-chain analytics becomes more than just data — it becomes a way to understand ownership, concentration, and power inside crypto ecosystems.
What you’ll learn:
How to reconstruct ERC-20 balances
Using UNION ALL for inflow/outflow logic
Creating reusable SQL queries with parameters
Ranking token holders by balance
Analyzing token distribution
Visualizing holder concentration with charts
