Welcome to Merlin API, the first smart portfolio tracker that shows you in-depth historical and current analytics about all your DeFi assets. You'll find all the documentation you need to start interacting with our API.


Investors in DeFi protocols find it difficult to track any profit/loss they make compared to their initial investment. Our wallet reporting tool, Merlin, provides understandable data for users to view and monitor their DeFi portfolio, assets and transactions across multiple protocols and blockchains.

What is Merlin?

Merlin is VALK’s DeFi Wallet Reporting tool, which retrieves the position of each digital asset deployed across DeFi protocols such as Aave, Compound, Lido, Uniswap and many ohter to calculate their positions (vs USD or other currency) plus yield generated. Merlin’s service is designed for investors who need to view Net Asset Value (NAV), daily PNL and the success of various individual strategies on a case-by-case basis, rather than just being presented with their overall portfolio value.
