How to pay with crypto: a step-by-step guide

Pick a coin, copy the address (or scan the QR), send the exact amount, wait for confirmations. The full New-U crypto checkout flow with the common first-timer mistakes called out.

What is Bitcoin? Digital gold, explained

A 21-million-coin supply cap, no central issuer, settlement without a bank. What Bitcoin is, why people call it “digital gold,” and what it is and isn’t good at as a payment method.

What is Ethereum? Programmable money, explained

More than a coin: a global computer that runs smart contracts. What ETH is, what “gas” means, and why most stablecoins live on Ethereum.

What is Solana? The fast payment rail, explained

Sub-second settlement and fractions-of-a-cent fees. Why Solana is often the cheapest way to send a payment, and the trade-offs versus Bitcoin and Ethereum.

Crypto wallets & seed phrases, explained

Hot vs cold, custodial vs self-custody, and the one rule that protects everything: never share your seed phrase. A jargon-free walk-through for first wallets.

Stablecoins explained: USDC, USDT & the dollar on-chain

A coin pegged 1:1 to the US dollar, so the price doesn’t move while you check out. What backs USDC and USDT, the networks they run on, and why they suit payments.
