What Is Cardano (ADA)?
Cardano is a proof-of-stake blockchain, and ADA is its native asset. ADA supports functions such as transaction fees and network participation; it is not a share in every company or application using Cardano.
Follow a transaction through the EUTXO model
Cardano's ledger represents spendable value through outputs. A transaction consumes permitted existing outputs and creates new outputs, with the extended model supporting assets and smart-contract conditions.2 This explains why a wallet's total balance and a proposed transaction's actual inputs and outputs deserve separate attention. The wallet prepares the action; the ledger enforces the rules.
Delegation is not the same as handing over keys
Cardano's staking design separates network participation from ordinary asset transfers.1 Read the actual wallet and delegation process rather than assume every service using the word ‘staking’ works the same way. An external operator offering a custodial product can introduce obligations and risks that are not properties of protocol-level delegation itself.
Understand what governance can change
Cardano governance has defined participation roles and decision procedures.3 An ADA holder should distinguish the right or ability to participate from a promise that a preferred proposal will pass. Treasury and protocol decisions are collective processes. Neither a governance role nor an application launch grants guaranteed income or immunity from network and market uncertainty.
Frequently asked questions
Is ADA an ERC-20 token?
No. ADA is native to Cardano, not an Ethereum token.1
Does Cardano host assets other than ADA?
Yes. Its ledger and EUTXO design support multi-asset and application functionality.2
Can a wallet's brand certify every token it displays?
No. Asset identity and application trust need separate checks.
