Sentio provides a powerful, all-in-one solution for transaction debugging, simulation, data indexing, and visualization, offering complete context in a single platform.
Sentio Debugger:
Best tool to help users understand how a transaction works. It has advanced features such as:
- Simulation: Run lightning-fast simulations and inspect the simulation result in great detail
- Dynamic logging: Add custom
console.logfor transactions to extract specific information, as part of a broader contract override feature - Code Insight: Navigate through Solidity code seamlessly, just like in an IDE
Sentio Indexer:
A state-of-the-art indexing service with integrated user experience:
- Support both Sentio processor, a blazing fast data indexer powered by the Sentio SDK that streamlines data ingestion, processing, and storage—all with maximum flexibility in TypeScript, as well as hosted subgraph processor
- Query using SQL/GraphQL and visualize results with an intuitive click-and-drag interface
Getting historical data on a smart contract can be frustrating when you’re building a dapp. The Graph provides an easy way to query smart contract data through APIs known as subgraphs. The Graph’s infrastructure relies on a decentralized network of indexers, enabling your dapp to become truly decentralized.
The Graph supports both Scroll mainnet & testnet.
Quick Start
These subgraphs only take a few minutes to set up. To get started, follow these three steps:
- Initialize your subgraph project
- Deploy & Publish
- Query from your dapp
Pricing: All developers receive 100K free queries per month on the decentralized network. After these free queries, you only pay based on usage at $4 for every 100K queries.
Here’s a step by step walk through that includes screenshots: The Graph Quick Start
