What is dune ?
Dune is a powerful tool for blockchain research, complete with all the tools you need to discover,explore,and visualize vast amounts of blockchain data. We can get data via a sql query and then present data as
- Bar charts
- Area Charts
- Scatter Charts
- Line Charts
- Pie Charts
- Counters
- Tables
Sql guides
Before we get into sql. In case you have no background on relational databases like mysql, let's break down what are relational databases.Relational databases contain a set of data tables so that a user can query some combination of tables to get only the subset of data (rows) they need.
Above is an example of a relational database.
With sql query we can get the data we need fast and efficiently.
Data sets
- Ethereum
- Gnosis chain
- Polygon
- Optimsm
- BNB smart chain
Create an dashboards via sql
WITH token_names as (
select * from
nft."tokens"
)
select name, symbol, count(*) as number_of_nfts
from erc721."ERC721_evt_Transfer" as scam_transfers
join token_names on token_names.contract_address = scam_transfers.contract_address
where scam_transfers."to" = '\x3E0DeFb880cd8e163baD68ABe66437f99A7A8A74'
AND scam_transfers."from" != '\x0000000000000000000000000000000000000000'
group by name, symbol
order by 3 desc
