Understand the project
Practical overview
When it fits
Use Otterscan when blockchain inspection should run locally alongside an Erigon node, particularly when reducing external query exposure and network round trips matters.
Who it is for
- Ethereum developers and operators running Erigon infrastructure
- Teams needing a locally queried blockchain inspection interface
- Builders adapting a local-node explorer for private or internal use
Documented uses
- Inspect Ethereum blocks and transactions
- Look up addresses and related blockchain data
- Query an operator-controlled node instead of an external third-party node
- Build a local explorer interface around Erigon node data
Before you choose
Requirements & limits
The repository is public and the software is open source under the MIT license. The documented setup is self-hosted and requires an Erigon node companion; no pricing or account requirement is documented.
- Whether the operator can provide the documented Erigon node companion
- Whether a self-hosted interface is preferable to an external explorer
- Whether local queries and custom client-level methods fit the intended data workflow
- Whether Optimism Superchain support through OP-Erigon is relevant
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
