Coinage: Stablecoins, Bitcoin, Chains, and the Rules
Coinage is a sourced educational library on stablecoins, bitcoin, blockchain networks, spending methods, and the regulation that governs each of them.
Coinage explains stablecoins, bitcoin, blockchain networks, spending methods, and regulation in plain language. Every figure carries its date and source. Every page names the documents behind its claims. Six hubs hold the library. Start with the topic you need; the trail of sources is the same everywhere.
Stablecoins
The stablecoins hub: how USDT and USDC back their tokens, how to read a reserve attestation, what happens in a depeg, and where the risks really sit.
Crypto Basics
The basics hub: what cryptocurrency is, how blockchain settlement works, the stablecoin types one by one, and a glossary that defines each term precisely.
Bitcoin
The bitcoin hub: how the network works, what mining actually does, where the price history sits, and how bitcoin compares with stablecoins for payments.
Spending & Use
The spending hub: how crypto-linked cards work, what off-ramps charge, which merchants take stablecoins directly, and how the six spending rails differ.
Regulation & CBDC
How stablecoin regulation works across jurisdictions: the US GENIUS Act, the EU MiCA framework, UK final rules, and the second wave now in consultation.
Chains & Infrastructure
The chains hub: eight networks compared on the facts that matter for moving stablecoins, from Ethereum and Tron to Base, Arbitrum, and Hyperliquid today.
What this site is
Coinage is a library about digital money: the tokens, the networks they run on, the ways to spend them, and the rules that govern all of it. It is built as six hubs, and every hub opens onto topic pages that carry their own sources and dates. Nothing here asks you to trust the site over the document.
The method is short to state. Every factual claim traces to a primary document. Statutes are read from the text as published on congress.gov, not from coverage of the text [2]. Reserve figures come from the reports accounting firms sign, under standards published by the AICPA [1], and this site reads those reports as issuer-commissioned attestations, not audits. Volatile figures carry the date they were true. Pages carry a last reviewed date that moves when the facts move.
The six hubs
Stablecoins is the largest subject. The stablecoins hub covers USDT and USDC in full, token by token, then the questions that apply to every token: how attestations work, how the majors compare, and what a safety review checks.
Bitcoin gets its own hub: how the network settles, what mining does, the price record with no predictions, and the comparison with stablecoins.
Eight networks carry nearly all stablecoin movement, from Ethereum and Tron through Base, Arbitrum, and Hyperliquid. The chains hub compares them on finality, fees, and design. The cost of sending register there holds the dated fee pull across all eight networks.
The spend hub covers the six rails that turn a stablecoin into a payment: cards, gift cards, direct merchant payment, peer-to-peer transfer, bill pay, and the on-ramps and off-ramps at both ends. It is an education hub; it recommends nothing.
The cryptocurrency hub holds the basics: what cryptocurrency is, how a blockchain settles, and the glossary.
Rules get their own trail, from the primary texts. The regulation hub carries the United States GENIUS Act, the EU MiCA framework, the UK final rules, and the second wave behind them, plus the central bank digital currency pages.
How to read any page here
Every page on this site works the same way. A summary answer sits at the top for readers in a hurry. The body explains, in sections, what the summary compresses. Sources sit at the foot of the body. A claim in the prose links to the entry it rests on, so a reader moves from a sentence to its document in one click. Data pages lead with tables whose rows carry their own dates. Token pages carry verified fact tables above the prose.
Two standing rules cut across every page. No page gives financial advice. No page predicts a price. No page recommends a product. And no figure appears without its date. A number without a date is a rumor with formatting.
Where to start
If you hold a stablecoin and want to know what backs it, start at stablecoins. If you want to move one, start at chains or spend. If the words themselves are the problem, start at cryptocurrency and work outward from the glossary. If the rules are the subject, start at regulation. Wherever you start, the sources follow you.
What this site is not
This is not a trading desk. There are no prices to watch here, no alerts, and no account. It is not an exchange review site. No issuer or vendor paid for placement, and none is asked to. It is not advice. Every page that touches money states facts and stops, because a reader’s decision belongs to the reader. The library exists so that decision, if made, is made against documents instead of marketing.
