Storage Slot Explorer

This tool provides a visual representation of a smart contract's storage layout, accepting either an on-chain address or the contract's code as input. It effectively handles all variable types, including complex structures like arrays,structs, and mappings.

Use it to precisely calculate the storage slot for any variable and obtain the corresponding Solidity or TypeScript code for that calculation.

Additionally, the explorer can fetch the value stored in a specific slot for both the current and historical blockchain states.Start Exploring

Fact Hash Calculator

This utility computes the fact hash for program executions, compatible with both the L1 Sharp Verifier and the L2 Integrity Verifier.

It offers valuable visualizations detailing how the hash is constructed, covering scenarios like bootloaded versus non-bootloaded executions.

The calculator is particularly useful when working with Atlantic service. Its seamless integration with Atlantic streamlines the process of verifying program execution integrity.Start Hash Calculation

Merkle Mountain Range Visualizer

Explore the structure and mechanics of Merkle Mountain Ranges (MMRs) with this interactive visualization tool.

Since our Storage Proofs service relies heavily on MMRs, this tool offers crucial insights into their functionality. Understanding how MMRs append data and generate proofs becomes much clearer through visualization.

Complementary articles are also available, delving deeper into MMR concepts and the workings of specific internal functions.Visualize MMRs
