@ -175,7 +175,7 @@ As a result, a multitude of new token standards were and are still being develop
Like ERC20, ERC777 is a standard for <<different-kinds-of-tokens,_fungible_ tokens>>, and is focused around allowing more complex interactions when trading tokens. More generally, it brings tokens and Ether closer together by providing the equivalent of a `msg.value` field, but for tokens.
The standard also bring multiple quality-of-life improvements, such as getting rid of the confusion around `decimals`, minting and burning with proper events, among others, but its killer feature are *receive hooks*. A hook is simply a function in a contract that is called when tokens are sent to it, meaning *accounts and contracts can react to receiving tokens*.

A hook is simply a function in a contract that is called when tokens are sent to it, meaning *accounts and contracts can react to receiving tokens*.
This enables a lot of interesting use cases, including atomic purchases using tokens (no need to do `approve` and `transferFrom` in two separate transactions), rejecting reception of tokens (by reverting on the hook call), redirecting the received tokens to other addresses (similarly to how xref:api:payment#PaymentSplitter[`PaymentSplitter`] does it), among many others.
