Setup & First Transaction
This is the hands-on on-ramp. By the end you will have a working environment, your tool of choice installed, and a real transaction submitted to a Cardano testnet, all without spending real ADA. It assumes you have the mental model from Cardano Fundamentals and its Core Concepts; if a concept here is unfamiliar, those pages explain it.
The path
- Choose your tools: pick an SDK for your language and get a provider key
- Networks & test ADA: pick a network, get free test ADA from the faucet, and find an explorer
- Set up your AI assistant: optionally give your AI coding assistant current Cardano context before you start writing code
- Your first transaction: build, sign, and submit a payment, then read it back from the chain
Choose your tools
Pick a Cardano SDK for your language and get a provider key, the two choices you make before building.
Networks & test ADA
Choose a Cardano network, get free test ADA from the faucet, and find a block explorer.
Set up your AI assistant
Use AI coding assistants to build on Cardano with current, authoritative context instead of stale training data.
Your first transaction
Build, sign, and submit your first Cardano transaction on testnet with Evolution, Mesh, or cardano-cli, then read it back from the chain.
Transaction building
Go beyond a simple payment: multiple outputs, coin selection, batching and airdrops, transaction chaining, resilient submission, and redeemer indexing, with Evolution and Mesh.
Query the chain
Read Cardano on-chain data (UTXOs, balances, datums, protocol parameters, delegation, and transaction status) through a provider, with Evolution and Mesh.
Transaction failures
Why Cardano transactions fail, the two-phase validation model, build-time versus submit-time errors, and which failures are retryable.
Where this leads
Once you can send and query a transaction, you are ready to build real things: mint native tokens and NFTs, or move on to smart contracts.
