UnblockPay

UnblockPay is a stablecoin banking API that bridges blockchain rails and traditional financial infrastructure, giving businesses a single integration point for cross-border payments, fiat-to-stablecoin conversion, and on-chain disbursements — with Latin America as its primary focus.

What Problem It Solves

Cross-border payments into and out of Latin America are expensive, slow, and operationally complex. Businesses that want to use stablecoins for international settlement face a fragmented stack: they need blockchain wallets, compliance infrastructure, liquidity providers, and connections to local payment rails like Brazil's Pix or Mexico's SPEI — all managed separately. UnblockPay collapses that stack into a single API, positioning itself as "BaaS for stablecoins" (Banking-as-a-Service for stablecoins), so that currency exchange brokers, payment companies, small banks, and fintechs can integrate stablecoin-powered international payments without building the underlying infrastructure themselves.

Core Mechanism

UnblockPay's API orchestrates four layers simultaneously: blockchain networks, liquidity providers, compliance tooling, and local payment rails. When a business initiates a cross-border payment, UnblockPay handles the conversion between fiat and stablecoins (USDC or USDT), routes funds through the appropriate local rail on the destination side, and manages the on-chain settlement — all within a single API integration.

Supported blockchains include Solana, Ethereum, Base, and Polygon PoS. Solana is a first-class network on the platform: UnblockPay supports native USDC-to-USDC transfers on Solana for automated payouts, treasury rebalancing, and crypto-native disbursements. All stablecoin-to-stablecoin transfers occur within the same network (cross-chain swaps are not supported at this time), which keeps each transaction path simple and auditable.

On the fiat side, the platform integrates with Pix (Brazil), SPEI (Mexico), SEPA (Europe), SWIFT, ACH, and Fedwire, enabling direct connectivity into local banking infrastructure across 150+ countries.

Key Products and Features

Global Payments — Cross-border money movement leveraging local rails in Latin America, the US, and Europe. UnblockPay supports both first-party and third-party payment flows, meaning businesses can send funds on behalf of their own accounts or programmatically route payments to end recipients.

Virtual Accounts — Businesses can provision USD and EUR virtual accounts with dedicated bank details for collections, alongside segregated stablecoin wallets on each supported blockchain. Fiat deposits can be auto-converted to stablecoins upon receipt, enabling ongoing treasury management in stablecoin form.

On/Off-Ramps — Businesses operating in Argentina, Brazil, Chile, Colombia, and Mexico can convert between local fiat currencies (BRL, MXN, and others) and USDC or USDT. This covers use cases including payroll to local employees, B2B supplier payments, and payment settlement for platforms operating across multiple Latin American countries.

Developer API — A single REST API covers the full range of operations: wallet creation, stablecoin transfers, fiat withdrawals, collections, and account management. The platform operates 24/7, includes a sandbox environment for testing, and delivers webhooks for event-driven integrations. Revenue for platform operators comes through configurable spreads and fees on transactions.

Compliance Layer — UnblockPay embeds KYC, KYB, and AML checks directly into the customer onboarding flow, integrating Sumsub for identity verification. Real-time transaction monitoring, counterparty screening, and per-customer transaction limits are included out of the box, reducing the compliance burden for businesses that would otherwise need to build or license this infrastructure separately.

Supported Assets and Markets

Stablecoins: USDC and USDT across Solana, Ethereum, Base, and Polygon PoS.

Fiat currencies: Brazilian Real (BRL), Mexican Peso (MXN), US Dollar (USD), and Euro (EUR).

Active Latin American markets: Argentina, Brazil, Chile, Colombia, and Mexico.

Team and Background

UnblockPay was founded in 2025 by three Brazilian fintech veterans. CEO Lucca Freire and CTO Pedro Henrique Braz previously co-founded Trampolin, a banking-as-a-service platform that was acquired by Stone — one of Brazil's largest payment processors — in 2021. COO Fabio Thiele brings a capital markets background from M&A work at BNP Paribas. The team's prior experience building regulated financial products within Brazil directly shapes UnblockPay's approach: compliance and local-rail expertise is baked into the product rather than bolted on.

In April 2026, UnblockPay closed a $4.5 million seed round led by Prelude, with participation from Plug and Play, Wintermute (a major crypto market maker), Reverie, Signature Ventures, Triaxis Capital, and Crescera Capital, plus angel investors from Stone, Zoop, and iFood. Capital is earmarked for geographic expansion, product development, and strengthening its regulatory and compliance framework. In its first year of operation, the company processed over R$300 million in transaction volume. Clients include Mercado Bitcoin, one of Brazil's largest cryptocurrency exchanges.

Circle Alliance and Ecosystem Position

UnblockPay is a member of the Circle Alliance, reflecting its deep integration with USDC as a primary settlement asset across all supported chains including Solana.

Within the Solana ecosystem, UnblockPay functions as a liquidity bridge: it brings institutional-grade, compliant fiat on/off-ramp infrastructure to Solana-based USDC flows, which is a persistent gap for businesses that want on-chain settlement without building compliance plumbing themselves. Solana's low fees and fast finality make it structurally attractive for cross-border payment use cases in Latin America, and UnblockPay addresses the last-mile problem for those flows — converting on-chain USDC into local fiat via Pix or SPEI, or collecting local fiat and settling on Solana. By abstracting regulatory, liquidity, and rail-connectivity challenges behind a single API, UnblockPay lowers the barrier for businesses to use Solana-native stablecoins in markets where dollar access is valuable but regulatory complexity is high.
