Most tutorials are using algodv2.
If you find a tutorial that is using algodv1, let us know on this thread so that we can fix it.
To get started, there are many ways:
- Go over “Start Building” and “Explore Features” sections of 1. Workspace Setup - Algorand Developer Portal
- Read Getting Started on Algorand | Algorand Developer Portal
- If you are more hands-on and want a very step-by-step tutorial, do: GitHub - algorandfoundation/buildweb3: Repository for the Algorand class of the "Building with Blockchain for Web 3.0" course (https://buildweb3.org)
Specifically for:
- transaction fee/read/write txs: 3. Your First Transaction - Algorand Developer Portal
- indexer: Searching the Blockchain (Indexer V2) - Algorand Developer Portal
- hash time lock seems still in v1.
