What a reserve attestation does not prove

A reserve attestation reports the procedures an accountant performed, often on assets at one moment. It does not, by itself, prove that liabilities are complete or that a firm is solvent.

What a token approval allows a contract to do

A token approval is a standing permission for a contract to move that token up to the amount you set. Closing the website does not cancel it.

What gas measures on Ethereum

Gas is a measure of computation and storage, not a second coin. Since EIP-1559, the fee has a protocol base fee and a tip.

An Ethereum account is not a Bitcoin UTXO

Ethereum keeps accounts with a balance, a nonce, and, for contracts, code and storage. That is a different record from Bitcoin’s unspent outputs.

How to read an ERC-20 approval

An ERC-20 approval lets a named contract move up to a stated amount of your tokens. It is not a payment, and “unlimited” means the cap was set extremely high.

A market-cap figure is not cash on hand

A crypto market cap multiplies a price by a supply figure. It is not cash in a treasury and it is not a bid for every coin.

What a funding rate describes

A funding rate is a periodic payment between longs and shorts on a perpetual contract. The sign says who pays. It is not a forecast and not a dividend.

What “a layer 2 inherits security” should mean

A layer 2 inherits a base chain’s security only to the extent that its data, its proof, and its exit rules are actually enforced there. The slogan is not a property of every network that says “L2.”

Bitcoin dominance is a ratio, not a verdict

Bitcoin dominance divides one market cap by another. Change the denominator and the ratio changes. It does not decide what bitcoin is worth.

A mempool is local, not global

Each node keeps its own pool of unconfirmed transactions. There is no single global mempool that every transaction enters.

A connect screen can be copied

Any website can imitate a wallet connection screen. The request that matters is the one your wallet itself displays, and connecting is not the same as signing.

How to read a transaction you did not expect

An unexpected transaction is a set of fields you can read: what moved, who was paid, which contract ran, and which earlier permission it used.

A seed phrase is not a screenshot

A seed phrase is a backup of the keys that can spend the coins. A photo, a cloud file, or a chat message is a copy of that backup.

What “qualified custodian” is claiming

“Qualified custodian” is a defined term in the U.S. rule for investment advisers who hold client funds or securities. A platform’s promise that it stores coins is a different sentence.

A securities question is not the same question as a commodity question

U.S. law asks a securities question under the Securities Acts and a commodity question under the Commodity Exchange Act. One answer does not automatically decide the other.

A 24-hour volume number is not one marketplace

A 24-hour volume figure adds up trades under somebody’s rules. It is not a single marketplace, and it is not a measure of how much you can sell without moving the price.

#Markets

[BlockWorld Media @BlockWorldMedia]

Spot markets and perpetual futures make different claims

A spot trade moves the asset. A perpetual futures contract creates a bet that is kept near an index by funding payments. The two prices can diverge.

Full nodes and lightweight clients

A full node checks the rules for itself. A lightweight client asks for evidence that a payment is in a block, and it trusts other people for the rest.

[BlockWorld Media @BlockWorldMedia]

A smart contract is deployed bytecode

Ethereum stores and runs bytecode. Solidity, the compiler, and an explorer’s “verified source” are tools around that bytecode, not the thing the chain executes.

What a spot Bitcoin ETF application is asking a regulator to allow

A spot bitcoin ETF application asks a U.S. regulator to allow an exchange to list shares of a trust that holds bitcoin. It does not ask the regulator to approve bitcoin.
