The problem Blockspect solves

Blockspect helps crypto investigators analyze data of a particular address(criminal) from the blockchain. It visualizes transaction flow and makes it easy to understand what is happening in the wallet and where the funds are flowing.
Not only it visualizes erc20 tokens but also nft transactions.

We also have added two tools till now-
Spam Nfts: To detect whether an nft is fake or original.
Whale Transactions: To Monitor large and interesting transactions as they happen

Challenges we ran into

We tried to get more data on each transaction like the owner of the address (eg exchange name or defi protocol) but couldn't find a good API.
