BNB Chain
Gnosis
You shouldn't need to build a rocket to query your own contract data.
Blockchain data is open, but accessing it shouldn't feel like rocket science. We made it simple.
Slow Development
Waiting days or weeks to deploy and map a subgraph just to get basic data.
Reorg Headaches
Constant manual handling of chain reorganizations and data integrity issues.
High Infrastructure Costs
Paying expensive RPC providers to backfill historical data again and again.
Vendor Lock-In
Being forced into proprietary solutions with limited API options and no export.
The Easiest Path from ABI to API.
Built for developers who want to build apps, not manage indexers.
Instant Indexing
Go from ABI upload to indexed API in minutes, not hours. Our optimized engine handles the heavy lifting.
Reorg-Proof
Built-in strategy handles chain reorganizations silently and automatically.
Flexible Data
Access events via REST, GraphQL, Webhooks, and WebSockets.
Pay-As-You-Go
Transparent, credit-based billing. Only pay for the resources you actually consume.
Schema Generation
Automatically map complex Solidity types like `uint256` and `address` into optimized SQL.
Custom Filtering
Powerful Query Service allows complex filtering and sorting on any event parameter.
Developer Tooling
Includes API Key management, detailed usage metrics, and webhook retry configurations.
How It Works
From contract to API in three simple steps.
Upload & Configure
Upload your smart contract ABI and specify the chain and address.
Auto-Magic Indexing
WormLayer automatically generates the schema, indexes history, and syncs real-time.
Query & Integrate
Use your auto-generated API keys to integrate real-time event data into your app.
Fair Pricing. Pay Only for What You Use.
No contracts, no fixed tiers, no hidden fees. Buy Worm Credits, use them for indexing and queries.
