Can you build infrastructure aligned with BCB's new VASP licensing regime?

Yes, we build the custody, reporting, and audit-logging infrastructure commonly expected under BCB's 2023 crypto-asset licensing framework.

What is a DeFi platform?

A DeFi (decentralized finance) platform offers financial services — trading, lending, staking, yield — through smart contracts instead of a centralized intermediary.

How are DeFi protocols secured against exploits?

Through audited smart contracts, reentrancy and flash-loan protections, rate limiting, multi-sig admin controls and an ongoing bug bounty program.

What is a typical build timeline?

A single-product DeFi platform typically takes 3–5 months including audit time.

Do you build cross-chain bridges?

Yes, though bridges carry higher exploit risk industry-wide, so we apply additional security review.

DeFi Development Services in Brazil

Decentralized finance lets businesses offer trading, lending, staking and yield products without traditional intermediaries — but it also means the smart contract is the product, mistakes are public, and attackers actively probe protocols. Hurain Technologies builds DeFi platforms with security woven into the architecture from day one, drawing on real-world exploit patterns. In Brazil, that means building to the technical expectations of Americas: Brazil's 2023 crypto-asset law gives the Banco Central do Brasil (BCB) direct authority to license and supervise virtual asset service providers, a significant shift from the prior unregulated environment.

The Challenge

Problems we see teams struggling with

Smart contract exploits

Reentrancy, flash-loan attacks, and oracle manipulation drain protocol funds.

Thin initial liquidity

New protocols struggle to offer tight spreads without market-maker integration.

Protocol parameter tuning

Tokenomics and incentive models need to be modeled and tested against edge cases before launch.

Regulatory uncertainty

DeFi governance and token structure must be designed with legal counsel from day one.

Oracle manipulation risk

Protocols relying on a single or thinly liquid price source are vulnerable to attackers temporarily distorting the price feed to their advantage.

Governance capture risk

Token-weighted voting without safeguards can let a large holder or coordinated group push through protocol changes that benefit them at the expense of other participants.
