How it works

Three steps from PIX to USDT

No manual reconciliation, no external dashboard. Every charge is one HTTP call.

  1. 01

    Create a charge via API

    POST /v1/charges with amount and externalId. Response includes QR code, copy-paste payload and brcode in base64.

  2. 02

    Customer pays PIX

    The payer scans or pastes the code in their bank app. You receive an idempotent webhook when payment is confirmed.

  3. 03

    USDT in your balance in 30s

    Conversion is automatic. The workspace's USDT balance is credited, fee is deducted, dashboard updates in real time.

Features

Everything you need to run PIX↔USDT

PIX In

Receive PIX payments with dynamic QR codes. Confirmation by central bank webhook in seconds.

PIX Out

Send PIX debiting from USDT balance. Conversion at the current rate, with transparent per-operation fee.

USDT on-chain withdraw

Withdraw to external wallet on Tron or Polygon networks. Gas covered, no surprise at the destination.

Multi-member workspaces

Invite your team with OWNER, ADMIN or MEMBER roles. Custodial balances isolated per workspace.

Idempotent webhooks

Every event carries externalId. Reprocess freely without double-crediting or triggering conversion twice.

Real-time dashboard

Live balances, transactions and metrics. Export CSV, audit per user, configure alerts.

Developer-first

One HTTP call. Without becoming an exchange.

Forget custody, exchange KYC, PSP integration. You talk to a REST API; we handle PIX, conversion and USDT.
