Can you support a BCB-regulated virtual asset service provider in São Paulo?

Yes, we build the technical infrastructure and AML/KYC controls commonly expected under Brazil's BCB crypto-asset oversight regime.

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's the difference between custodial and non-custodial wallets?

Custodial wallets hold private keys on your behalf with easier recovery; non-custodial wallets give users full control of their private keys.

Which blockchains can the wallet support?

Bitcoin, Ethereum and EVM-compatible chains, Solana, Tron and others based on your product's needs.

Can the wallet include staking or in-app swaps?

Yes, staking, swap and on/off-ramp features are common additions we build directly into the wallet.

How long does it take to build an MVP wallet?

A focused MVP wallet typically launches in 8–12 weeks; a full-featured multi-chain wallet with swap and staking takes longer.

Cryptocurrency Wallet Development in São Paulo

Q: Do you support Pix integration for Brazilian payment platforms?

Yes, we integrate Pix alongside card and wallet payment methods within a unified orchestration and reconciliation layer.

Generic wallet apps rarely fit a specific product's compliance model or user experience needs. Hurain Technologies builds custodial, non-custodial, hybrid and smart-contract (ERC-4337) crypto wallets tailored to exchanges, Web3 platforms, gaming ecosystems and remittance products — with multi-chain support, in-app swap/staking, and full white-label branding. In São Paulo, that means building to the technical expectations of the local market.

São Paulo Market Landscape

Why wallet development is critical in São Paulo

São Paulo hosts the B3 stock exchange and the largest concentration of fintech unicorns and scale-ups in Latin America.
Brazil's Pix instant-payment system has driven exceptional real-time transaction volume, raising the bar for fraud detection and settlement infrastructure.
São Paulo-based crypto businesses now operate under Brazil's 2023 crypto-asset law, giving the BCB direct oversight of virtual asset service providers.

The Challenge

Problems we see teams struggling with

Limited wallet options for your product

Off-the-shelf wallets don't match your compliance model, supported assets, or UX requirements.

Custody security and key management

Keys must be secured on-device or on your infrastructure without exposing users to loss.

Multi-chain complexity

Supporting multiple blockchains from one wallet interface multiplies engineering effort.

User recovery and support friction

Seed phrase recovery is user-hostile; social recovery and secure enclave options solve this.

Poor UX driving support ticket volume

Confusing transaction confirmations, unclear gas fee estimates, and cryptic error messages generate a disproportionate share of support load for consumer wallet products.
