In the case of individuals or legal entities that are not considered cryptoasset exchanges, they will only need to provide information <mark style="background-color:purple;">when the monthly value of transactions carried out with cryptoassets exceeds R$ 30,000.00 (thirty thousand reais)</mark>, even if the transactions occur in a peer-to-peer (P2P) manner.

The Instruction sets out various information that must be reported, such as the date of the transactions, the holders, the cryptoassets used, among others.

The information must be provided <mark style="background-color:purple;">monthly</mark>, and, in the case of exchanges, they will only need to provide information about their users on December 31 of each year.
