Hashio

A JSON-RPC Relay Community Service

Hashio is a Swirlds Labs hosted service based on the open-source Hedera JSON-RPC-Relay. It provides a JSON-RPC API interface, on top of Hedera’s native API transactions, that offers a familiar Ethereum-like API.

The Hashio JSON-RPC relay implementation is in beta, offers limited functionality today, and is only available to developers. To contribute feedback or log errors, please submit them as issues in the GitHub repository.

Wallet Support

Use existing JSON-RPC supported wallets, such as Metamask, with the public Hedera previewnet, testnet, and mainnet. Hashio supports cryptocurrency transfers and transaction signing, enabling developers to test their EVM-based applications with ease.

Developer Tooling & Environments

Implement the public Hedera previewnet, testnet, and mainnet into JSON-RPC-supported development tools and environments. Hashio enables developers to utilize familiar toolsets for building new or porting existing EVM-based applications faster. Review a list of supported endpoints here.

Open Source

The JSON-RPC Relay is open source — anyone can review, compile, fork, and contribute back to the codebase.
