Uzuras Crypto Reference is a small, plain-English reference site about cryptocurrency fundamentals. This domain has a history in the crypto world, and the site continues in that spirit: explaining what tokens are, how wallets and keys work, what actually happens when a transaction is sent, and which U.S. agencies oversee different parts of the space.
Everything here sticks to durable, well-documented ground. Where a page leans on a specific claim, it links the primary source — the ERC-20 specification, the NIST blockchain overview, official Ethereum wallet documentation, and U.S. regulator pages — rather than paraphrasing secondhand summaries.
The most-used part of the site is the wallet types at a glance table on this page. It lays out the main categories of crypto wallets — hardware devices, app wallets, browser extensions, custodial accounts, and multi-signature setups — side by side: who holds the keys in each model, how recovery works, and what each is commonly used for. If you're trying to understand the difference between "the exchange holds it" and "I hold it," the table is the fastest way to see it.
From there, the guides go one question at a time: what an ERC-20 token is, how wallets and recovery phrases work, what happens when you send a transaction, and who regulates crypto in the U.S.. None of it is investment advice — it's the vocabulary and mechanics you need before any of the rest makes sense.
