Are Nano transactions really feeless?

Yes. Nano transactions require no fees. The sender performs a small proof-of-work computation (anti-spam), but no monetary fee is paid to validators or miners.

Can I swap XNO without KYC?

Yes. SyntheticSwap supports XNO swaps with no registration or identity verification.

How was Nano distributed?

Nano's entire supply was distributed for free via a CAPTCHA-solving faucet between 2015 and 2017. There was no ICO, no mining, and no pre-allocation to founders.

What is the block-lattice architecture?

In Nano's block-lattice, every account has its own blockchain. Send and receive are separate blocks, allowing parallel processing and instant, asynchronous transactions.

Is Nano environmentally friendly?

Yes. Nano uses no mining — Open Representative Voting requires only negligible energy. Nano's total annual energy consumption is estimated to be less than that of a single Bitcoin transaction.

About Nano

Nano (XNO, formerly NANO) is a cryptocurrency designed for instant, feeless digital payments. Originally distributed for free via a CAPTCHA faucet between 2015 and 2017, Nano uses a block-lattice architecture where each account has its own blockchain. Transactions are confirmed in under 1 second with zero fees, making Nano ideal for microtransactions and everyday payments. Nano uses Open Representative Voting (ORV) consensus — an asynchronous Byzantine Fault Tolerant protocol — rather than mining, giving it an extremely low environmental footprint. The entire supply of ~133 million XNO was distributed via the faucet with no pre-mine.

How to Swap XNO

Swapping Nano (XNO) on SyntheticSwap is simple and requires no registration or KYC. Connect your personal crypto wallet, select XNO as your source or destination asset, enter your receiving wallet address, and confirm the live exchange rate. Once you send XNO to the deposit address provided, SyntheticSwap processes the exchange automatically and delivers the destination asset directly to your wallet. No personal information is collected — fully non-custodial from start to finish.

How to Store XNO

XNO can be stored in wallets supporting the Nano network. Natrium (iOS/Android) is the most popular mobile wallet. Nault is a feature-rich web/desktop wallet. The official Nano Wallet Company app is also available. Ledger hardware wallets support XNO. Never store Nano on exchange wallets that charge withdrawal fees.
