While there exists many DIDs, this tutorial will focus only on
ethr DID. At the moment, OpenAttestation only supports
The creation of an
ethr DID is identical to the creation of a wallet, as it relies entirely on the ethereum architecture. Once the wallet will be created, we will need to retrieve its private key:

There are two information to keep very importantly for the next steps:
- the wallet address (
0xaCc51f664D647C9928196c4e33D46fd98FDaA91Din the example above)
- the private key (
0x7b227ac59116f3eeb2b265422cf3cbfbd244c525961fb297eb52153ec62aa845in the example above)
Please note that you will definitely get different values.
In order to make the tutorial easier to follow, we decided to reveal all the information about the wallet we used, including the private key. We used a throw-away wallet for that purpose. That means that we will never use this wallet again. It's very important that you NEVER SHARE THE PRIVATE KEY of your wallet.
