Shadow turns data consumers into data producers.

Write custom events into any contract, with full access to the entire state of the chain. Get everything in one table and export to your data tool of choice.
data_array
Access to any mainnet state
Emit data directly in shadow events that usually requires making separate RPC calls.
library_books
Access peripheral contract data
Get aggregator, fees, collection, and ENS data with simple view function calls.
history
No logs? No problem
Backfill historical event data going back to contract creation, even if logs are missing.
desktop_access_disabled
Reduce data engineering time
Eliminate the need to build and maintain data pipelines to merge onchain datasets.
cloud_off
Save on compute costs
Eliminate expensive multi-join queries by emitting shadow events in usable schemas.
deselect
No more tracing
Protocol doesn't emit an event you need? No problem. Emit a shadow event yourself.
price_change
Interest calculations made easy
Call contract view functions in events for data that requires onchain computation.
schema
Rapidly iterate on schemas
Shadow events frontfill instantly, and full historical backfills take less than 15 minutes.
multiple_stop
Standardize schemas across protocols
Create unified event schemas for similar protocols to reduce data transformations.

Clean onchain data ready for analysis. No pipelines needed.

Emit custom event logs for any contract, with powerful access to any mainnet state data. Get usable data exported fast – no extra engineering needed.
