Illuminating the Onchain World.
Build onchain products with limitless data, powered by an open protocol.Start Building
Onchain information is disorganized and unreadable.
The quantity of onchain applications is increasing exponentially — no centralized entity will be able to organize everything.
To solve this problem, an open network of curators contribute to the Zapper Protocol — transforming onchain data and empowering builders with an easy to use API.

An open interpretation layer, built by you.
We've created powerful tools allowing anyone to easily contribute and make blockchains human-readable. No coding is required.
Transaction Interpretation
Transaction Interpreters are used on onchain transactions to translate them into human-readable output, and augment them with contextual, and often off-chain, information.
Position Interpretation
App Token Interpreters are used to index app-centric token balances for users. This can be loans, deposits, pools, etc... The majority of these tokens do not have a market price; rather, they are priced based on the tokens they are redeemable for.

The ZAP token is central to the protocol 一 serving as an incentive to interpret onchain information and as a payment for accessing its data.
