# Developer Resources

HashSpheres run the same core stack as Hedera mainnet and testnet. Most Hedera developer resources apply directly to HashSphere.

### Hedera Portal

The portal connects to testnet and previewnet. It does not connect to HashSpheres. It is still useful for learning SDKs and Solidity patterns.
