Nubank Cripto: Brazilian app trading, spreads, transfers and custody

The conflict policy identifies the tension created when the same business quotes the price, supplies the asset and holds the resulting balance. Its stated controls include independent price references, separation of dealing and custody responsibilities, and review of provider relationships. These are disclosed controls, not an independently measured execution-quality result.[7]

A programmed purchase is an instruction to transact on its schedule. Its purpose differs from a desired-price order, which waits for specified execution conditions. Before comparing the two, separate the trigger, the amount committed and the price actually obtained; none is equivalent to a guaranteed investment return.

Ordinary purchases, sales and swaps can include a 0–3.5% NuCrypto spread. Limit-swap fees are charged on registration; cancellation, expiry or rejection refunds the unexecuted portion.[4]

Hypothetical purchase, assuming the 0.4% rolling-volume tier applies: R$2,000 less R$8 leaves R$1,992. At an assumed executed BTC price of R$402,000, the purchase yields 0.00495522 BTC.[4]

NuCrypto’s staking service fee can reach 20% of gross rewards. The app specifies the applicable terms.[4]

The economic comparison is the asset quantity received for the total reais paid, followed by the net reais obtainable on sale. A percentage labelled “fee” captures only part of that comparison when the dealing price includes a spread. Price movement between the two trades can exceed either explicit charge.

The current product FAQ says an incoming blockchain transfer remains pending until the customer supplies the required origin-of-funds declaration. A blockchain confirmation and an available app balance are therefore different events. The declaration is reached through the pending-transfers notice in the crypto area.[2]

The destination network, asset identifier and recipient details should be taken from the actual transfer screen. The number of coins advertised for buying is not a network-support matrix. A wrong-network transfer can also require cooperation from a recipient platform that NuCrypto does not control.

NuCrypto says its reserve arrangement covers customer obligations one-for-one and refers to independently audited proof-of-reserves reporting. This review did not establish a specific inspected audit’s date, scope, liabilities calculation or exclusions. That disclosure should not be presented as a verified current solvency opinion.[5]

The custody appendix describes multi-factor authentication, distributed control of key material, redundancy and recovery procedures. Such controls address different failure modes: a secure key system does not prevent a customer from authorizing an incorrect transfer, and operational recovery does not guarantee a particular execution price after an interruption.[6]

These inactivity provisions concern account functionality and termination. They should not be converted into an invented monthly inactivity charge. A client who expects to leave assets untouched needs to distinguish continued ownership from immediate ability to send them elsewhere.

USDC rewards have narrower eligibility than ordinary crypto access: an active account, age 18+, at least 10 USDC held at NuCrypto, and no US citizenship or residence, including temporary residence. Dropping below the qualifying balance suspends participation until the balance recovers.[9]

Nubank’s contact page links the Me Roubaram recovery service for a stolen phone, including account access, card blocking and password changes. The ombudsman route is for cases already raised with ordinary support. Neither published availability nor a recovery link establishes a tested response time or telephone execution service.[11]

The product FAQ explicitly describes operation under the transitional regime of BCB Resolution 520/2025. That wording is the relevant current status here; it is not evidence of a completed authorization decision. Crypto balances are expressly outside FGC, FGCoop and similar guarantee funds.[2]

Nubank reported more than seven million crypto clients on 17 March 2026. This is a useful measure of the service’s reach, but the announcement does not define it as monthly active traders or disclose an independently comparable exchange-volume series. The same release’s planned expansion of Earn Crypto is not evidence that every proposed asset or account has since been enabled.[10]

The conflicts disclosure acknowledges that NuCrypto can receive payments associated with stablecoin balances or issuer relationships. Its stated policy is to assess assets using objective criteria and disclose relevant arrangements. A reward paid by the platform should therefore be evaluated under its programme contract rather than assumed to be a blockchain-native yield.[7]

The tax-document guide describes a change to average-cost calculations from 2024, replacing its earlier last-in-first-out presentation. Retaining acquisition, sale, transfer and fee records is consequently useful when reconciling older holdings or assets moved between providers. This profile does not apply a tax threshold to a particular reader.[12]

No customer trading API, copy-trading mandate or autonomous AI execution service was established in the reviewed NuCrypto product and contractual materials. The documented automated feature is a customer-programmed purchase. A future interface or general Nubank AI announcement should not be treated as a crypto dealing permission without its own terms.
