What Onyxcoin is

Onyxcoin grew out of Chain, a company that spent years building blockchain infrastructure for financial institutions before turning toward open, community-run protocols. The XCN token became the thread tying that new direction together: it is used to vote on how the Onyx ecosystem changes and to pay for activity on the network.

Onyx Protocol started with lending markets where people can supply assets to earn interest or borrow against collateral, with XCN holders deciding which markets exist and how their risk settings are tuned. Proposals are raised and voted on through Onyx governance, and holders can delegate their votes to another address.

The project then built Onyx, its own chain designed around decentralised finance. The official documentation describes it as a Layer 3 network that settles to a larger chain, uses XCN as its gas token, and aims to give applications fast, inexpensive transactions while staying compatible with Ethereum tools. Its long-term bet is that finance apps work best on infrastructure tuned specifically for them.

For a buyer, SwapRocket delivers XCN as an ERC-20 token on Ethereum. Moving it onto the Onyx chain for gas or apps uses the project's own bridge, a separate step from buying.

How to buy XCN step by step

  1. 1

    Set up a wallet that can receive XCN

    Any Ethereum wallet works and the address starts with 0x. No memo is needed. Bridge to Onyx separately if you want to use XCN there. SwapRocket never holds your coins: they go straight to the address you enter.

  2. 2

    Pick the coin you will swap from

    Card and bank payments are temporarily offline, so you buy by swapping crypto you already hold, such as BTC or USDT. SwapRocket supports 1,000+ assets.

  3. 3

    Check the network and paste your XCN address

    SwapRocket delivers XCN as an ERC-20 token on Ethereum mainnet, not on the Onyx chain.

  4. 4

    Compare live quotes and send your deposit

    The swap box compares live rates from several exchange partners, with zero added fees from SwapRocket. Send the exact deposit amount to the one-time address shown.

  5. 5

    Receive your XCN

    Most swaps complete in under 10 minutes, depending on network confirmations. If anything looks stuck, 24/7 live support can check the order with you.

Häufig gestellte Fragen

What is XCN used for?

XCN is used to vote in Onyx governance and serves as the gas token on the Onyx chain.

Will my XCN arrive on the Onyx chain?

No. SwapRocket sends ERC-20 XCN on Ethereum. Moving it to the Onyx chain is a separate bridging step.

Can I buy XCN with a card on SwapRocket?

Not right now. Card and bank payments are temporarily offline, so you buy XCN by swapping another cryptocurrency, such as BTC or USDT.

Do I need an account to buy XCN?

No. Crypto-to-crypto swaps need no account and no KYC from SwapRocket; you only enter the address that will receive your XCN.

What fees does SwapRocket charge?

SwapRocket adds zero fees. The rate you see comes from the exchange partner, and the blockchain network charges its own transaction fee.

How long does a XCN swap take?

Most swaps complete in under 10 minutes, depending on how quickly the networks involved confirm the deposit.
