Cardano (ADA): questions and answers
Every answer below is written from the sources listed at the end of this page, with the date each one was checked.
The question that decides how you read Cardano
Cardano's defenders and critics agree on the facts and disagree about one thing: whether publishing the proof before shipping the code is discipline or delay. That is the question worth examining.
Cardano exists because of an argument inside Ethereum. In 2014 the founding group split over whether the project should be a commercial company or a non-profit foundation. Charles Hoskinson, briefly Ethereum's chief executive, left during that dispute — a sequence he has described in interviews, and which secondary accounts repeat, though no primary foundation record sets out the reasons.
What followed was a deliberate inversion of the prevailing method. Instead of shipping first and formalising later, Cardano would specify a protocol, submit it to academic peer review, and only then implement it.
What is still unsettled
The open criticism is not technical, it is commercial. Cardano has a rigorous protocol, a long publication record and a large delegating community; whether that has converted into application activity proportional to its size is disputed, and the answer depends heavily on which metric you pick. The research-first method also concentrates influence with the people who can read the research — a quieter centralisation than validator counts, and harder to measure.
What this means when you swap ADA
Modern Cardano addresses are Bech32 strings beginning `addr1`, and no memo or tag is used. Older Byron-era addresses still exist and look completely different; some services no longer accept them, so prefer the current format.
Two details catch people out. Cardano uses a UTXO model with a minimum-ADA rule: any output carrying native tokens must also carry a small amount of ADA, so a wallet holding tokens and no ADA cannot send them. And delegation never moves your coins — staking ADA leaves it in your own wallet and spendable, which is safer than it sounds but does mean rewards and balances update on epoch boundaries rather than instantly.
Common ADA questions
- How do I swap Cardano (ADA) instantly on Monivo?
- Pick ADA as the asset you want to receive, choose what you're paying with, paste your wallet address, and confirm. Monivo routes your order to the provider offering the best rate, and most swaps complete in under 10 minutes — no account needed.
- Can I swap ADA with no KYC?
- Yes. Crypto-to-crypto swaps of ADA on Monivo require no identity verification and no sign-up. Only fiat purchases (card or bank transfer) require KYC, because banks and payment processors mandate it.
- Is swapping Cardano on Monivo non-custodial?
- Yes. Monivo never holds your funds. ADA is sent directly to the wallet address you provide, so you stay in control the whole time.
- Which network does ADA use here?
- Monivo supports Cardano on the Cardano network. Always double-check that your receiving wallet supports this network before confirming.
- What fees apply when I swap ADA?
- Monivo adds zero fees on top. The quote you see already reflects the best aggregated rate across connected providers, including their network and processing costs — all fees are included in the shown amount.
- Does staking ADA lock my coins?
- No. Delegating to a stake pool assigns your balance's voting weight to that pool but leaves the ADA in your own wallet, spendable at any time. There is no bonding period and no slashing on Cardano, though rewards are paid per epoch rather than continuously.
- Why does sending a Cardano token also require ADA?
- Every transaction output on Cardano must carry a minimum amount of ADA, and outputs holding native tokens need slightly more. If your wallet has tokens but no ADA, it cannot construct a valid transaction — keep a small ADA balance for fees and the minimum-output rule.
- Do I need a memo to deposit ADA?
- Generally no — a Cardano address is self-contained. A small number of platforms still issue shared deposit addresses with a reference, so follow the instructions shown by the receiving service rather than assuming.
