Welcome to the 0xProcessing blog. We discuss crypto payment processing, share our clients’ successful cases, and talk about the cryptocurrency market here. Really, that’s mostly what we are interested in.

What Is a Crypto Payment Gateway and How Does It Work?

"Seen" and "settled" are different states, and shipping on the first one is how merchants lose goods. Bitcoin is visible in seconds and final in an hour. Solana is sub-second confirmed, finalized in thirteen. This guide walks a crypto payment from checkout to settlement, then covers the decisions that follow: custodial or non-custodial, and who holds your money before it lands; five integration routes ranked by developer effort; static versus dynamic addresses and what breaks with the wrong choice; whether to settle in crypto, stablecoin or fiat. Plus the edge cases nobody mentions until they happen – underpayment, overpayment, duplicate, wrong network – and a pre-integration checklist of eight things to confirm before signing.

MiCA Regulation and EU Crypto Rules: A Practical Guide for Merchants

If you accept crypto as payment, MiCA almost certainly doesn't license you. It licenses the provider processing, holding or converting it on your behalf – and most coverage misses that distinction because it's written for exchanges. This guide answers "does this apply to me" first, then covers what changed on 1 July 2026 when grandfathering ended with no transitional cover left anywhere in the bloc. Which stablecoins survived: 17 authorized issuers as of April, 22 by August, USDC and EURC clean, USDT delisted but not banned. Inside: where a merchant crosses into CASP territory without noticing; the fiat leg nobody mentions, where a separate PSD2 licence sits in your payment chain; and a five-minute provider check against the ESMA register that's the single most useful thing you can do after reading.

Crypto Liquidity Providers

Sell 10 BTC into an order book that shows $100,000 and you don't get $1,000,000. You get $991,200 – the book thins out as you eat through it, and the last coin clears at $99,300. For a miner selling production every month, that gap compounds into a number worth managing. This guide walks the order book arithmetic, then the four ways around it: market makers, liquidity providers, OTC desks and prime brokers, which are not interchangeable despite being used that way. Inside: what an OTC trade actually costs versus the spread you're quoted; how algorithmic orders split a position so it doesn't move the price; settlement and counterparty risk when the desk holds your coins; and the volume threshold below which a payment processor covers the same requirement at lower overhead.

iGaming Payment Solutions in 2026: What Operators Actually Need

Gateway, PSP, orchestration platform – operators use the three words interchangeably and then buy the wrong thing. They solve different problems, and the gap shows up six weeks into integration. This guide separates them, then walks the full payment path from the moment a player taps deposit to the moment records reconcile, in parallel for traditional and crypto rails. Where it breaks is the useful part: declined cross-border cards, rolling reserves an acquirer imposes on a licensed operator, payouts that clear the risk check and then wait for a banking window. Inside: the real cost stack on both rails, including the lines that don't appear in a quote; four setups compared, from crypto as a cashier option to a dedicated crypto-native gateway; build versus buy, honestly; and eight claims providers make – "we support USDT", "low fees", "AML included" – with the follow-up question that makes each one mean something.

Crypto in iGaming Payment Solutions: Deposits, Payouts, Rules

A card rail costs an operator 5–9% all-in once the rolling reserve, chargebacks and FX spread are counted. The headline rate is the smallest part of that, and VAMP tightened the rest in 2026. This guide prices both rails side by side, then gets practical. Why TRC-20 dominates player deposits and what happens when someone sends on the wrong network. How closed-loop withdrawals work and where the manual review threshold should sit. What actually happens when KYT flags a deposit — who decides, where the funds sit, and when the player hears back. Inside: the metrics that tell you the rail is working, and nine questions to put to any provider claiming they onboard iGaming — starting with which licence and which jurisdictions.
