Simple examples that show how to use Arweave

See https://pencilflip.medium.com/how-to-use-arweave-to-store-and-access-nft-metadata-823552293f62 for a more in-depth walkthrough.

Setup

In order to run this code, you need to generate a new Arweave wallet. Follow https://docs.arweave.org/info/wallets/arweave-web-extension-wallet#new-users-generating-your-wallet in order to do this. Once you do it, create a .env file and set KEY=YOUR_KEY.

Running the code

There are five scripts.

1. yarn readAccount—this is a simple example of how to read basic data about your Arweave wallet.
2. yarn readTx TX_ID—reads the data of a transaction.
3. yarn txStatus TX_ID—this gets the status of a single transaction.
4. yarn submitTx—shows how to submit a transaction using arweave.transactions.post and read the data back.
5. yarn arbundles—shows how to submit a transaction using arbundles (which is more robust than arweave.transactions.post) and read the data back.
