​
Mainnet Account Creation

DEVELOPMENT ACCOUNT:Go to the Hedera Portal to create an account on testnet and use that for development (it’s free and you don’t need to buy hbar). If/when you need a mainnet account (where transactions cost real hbar), it’s best to create that mainnet account through one of the supported wallets.EXAMPLES & DOCUMENTATION:We have SDKs for Java, Javascript, Go, and .NET. There are examples in the GitHub repositories for the SDKs. Technical documentation is available online.HELP FROM HEDERA & COMMUNITY:Reach out any time to the community of developers and Hedera/Hashgraph team members in the Hedera Discord server.ADDITIONAL LEARNING RESOURCES:
Please visit the Hedera buying guide for a list of known third-party wallets across mobile (iOS / Android), desktop, hardware, and custodial, which support HBAR cryptocurrency and instant Hedera account creation.Hedera does not endorse or recommend any specific wallet provider.
Yes, many applications are currently deployed on the Hedera mainnet, generating millions of transactions per day. However, we recommend starting application development on the Hedera testnet, before migrating to the mainnet.To get started building on the Hedera testnet or mainnet, please visit the official developer documentation.The Hedera developer quick-start guide is also available.
The Hedera mainnet supports developers using all of Hedera’s network services.The network services on the Hedera mainnet are throttled.The Hedera developer quick-start guide is also available.
During the mainnet beta period, it is expected that the network will experience very brief periods of scheduled downtime for maintenance.Anticipated maintenance activities include adding additional nodes to the network and updating the core software running on mainnet (beta) nodes. The network’s consensus state will remain unchanged in the case of any downtime or network failures, and any transactions sent to the network during periods of downtime will be rejected.The status of Hedera’s mainnet and testnets is publicly available at status.hedera.com.

Testnet Account Creation

To start building and testing your application on the Hedera testnet, you’ll need to create a Hedera account.Step 1: Create a Hedera Developer Portal profile and confirm your email address.Step 2: After logging into the Hedera Developer Portal, select “Testnet” from the network drop-down menu.Step 3: Click or tap the “Create Account” button to generate your public / private key pair and account ID for use with the Hedera SDK — the public / private key and Hedera account ID will appear in a moment.Step 4: Start building on the Hedera Testnet by visiting the official documentation and selecting your language.
You’ll first need to follow these instructions to create an account on the Hedera testnet.After you’ve created your account, visit the official documentation and select your language to get started building.
The Hedera testnet supports developers using all of Hedera’s network services.The network services on the Hedera testnet are throttled.The Hedera developer quick-start guide is also available.
Applications built on Hedera testnets require testnet cryptocurrency to utilize the Hedera services for application development. Testnet cryptocurrency does not have any value.Fees on the Hedera testnet are the same as the mainnet; you can find the fee schedule and estimator here.

​
Previewnet Account Creation

The Hedera developer community and our ecosystem partners have expressed interest in early access to Hedera codebase features and functionality, prior to their release on the Hedera testnet and mainnet. In response to this feedback, we started looking into the idea of a second testnet — the “previewnet” — which would run a development version of the Hedera codebase.The Hedera previewnet is designed to offer developers in the Hedera community early exposure to features coming down the pipe. It’s not always stable and accounts / data are likely to be lost when the network codebase is upgraded.As of right now, you’ll need to use the latest version of the SDK in the language of your choice to interact with the previewnet. You can find all of the Hedera SDKs in our documentation.The source of truth for Hedera network, mirror node, and planned network upgrades for Hedera’s mainnet, testnet, and, now, previewnet, will always be available at status.hedera.com.
The Hedera previewnet supports developers using all of Hedera’s network services — it will be the first to support any up-and-coming services, as well.The network services on the Hedera previewnet are throttled.The Hedera developer quick-start guide is also available.
First, follow these instructions to create a previewnet account in the developer portal.Once your accounts are ready, head to Getting Started to begin building.
To build and test your application on the Hedera previewnet, you’ll need a Hedera account.
