Etherscan for your blockchain

Ethernal is an open source block explorer for public & private EVM-based chains.

See blocks and transactions. Interact with your contracts. Decode functions, events, and variables data.


Connects To Any Chain

Ethernal is an explorer that works with any EVM-based chains, so you can connect it to your local Hardhat or Ganache node, it supports Ethereum, Matic, BSC, Avalanche among all others...
And if your chain is running remotely, you'll be able to connect to it as well!

Automated Sync

All blocks, transactions and contracts are automatically synced with Ethernal.
The explorer then displays them all in simple UI along with relevant data such as function calls or emitted events.

Contract Interaction

Using contracts metadata, Ethernal automatically generate an interface for you to easily interact with all your read & writes methods.

Transaction Tracing

Transaction tracing displays internal calls to other contracts, as well as internal contract creations.
Contract calls are automatically decoded by matching the bytecode with your other contracts or by looking up the metadata on Etherscan.

Variables Decoder

Contract variables are automatically decoded for each block.
You can easily inspect the value of each integer, mapping, struct, etc...declared in your contracts, even private variables.

Integrates with the tools you are already using.
