Programmable payment conditions
24/7
Settlement availability
Agents need to pay for compute, settle invoices, or purchase services. They can't open bank accounts. BRRR gives them programmable spending rails without a human in the loop.
Smart contracts set the limits: per transaction, per day, per counterparty, per geography. Cryptographic guardrails, not policy documents. Auditable, tamper-proof, real-time.
No buttons, no manual workflows. Agents execute smart contract calls that trigger fiat payments, cross-chain transfers, and reconciliation automatically. Built for machines.
BRRR's accounting network tracks input/output across multiple agents. Swarms of autonomous actors settle, split, and reconcile without a central treasury manager.
Create programmable wallets for autonomous agents without manual setup, enabling immediate participation in financial workflows.
Enforce transaction limits and permissions directly in code to ensure consistent policy execution and auditability.
Transmit transaction updates instantly so agents can operate using accurate, up-to-date financial information.
Manage funds across multiple networks from a unified treasury structure that reduces fragmentation.
MPP to 402 to cards to wires. Execute payments across blockchain and traditional rails through one programmable interface.
Everything you need to know about BRRR.
BRRR is a developer infrastructure for programmable payments. It provides APIs and SDKs for building deposit, withdrawal, and orchestration products. Through BRRR, AI platforms can give autonomous agents full control over spending, balance checks, card top-ups, fiat payments, and cross-chain transfers.
Agents call dedicated API endpoints to query balance, request funds, or make online purchases. The API handles conversion, settlement, and card loading automatically. Spending limits are set by the account holder via the dashboard, agents operate autonomously within those limits. No human approval needed at runtime.
AI platforms and agents that need to transact in both the on-chain and fiat world. Every function is an API call, no forms, no buttons, no manual workflows. Agents trigger fiat payments, cross-chain transfers, and reconciliation through standard HTTPS calls. Built for machines from the ground up.

BRRR supports USD, EUR, CHF, and GBP in fiat currencies. All major stablecoins including USDC, USDT, USDE, USDS, and RLUSD; and 30,000+ other tokens across 20+ blockchain networks.
Yes. Agentic Payments are built for fully autonomous, 24/7 operation. Agents can check balances, top up their card, and retrieve card details to complete purchases, all without a human in the loop. Each agent operates with its own bearer token and a cumulative EUR spending limit set by the account holder, so there is always a human-controlled ceiling on what any agent can spend. A ready-made MCP server is available, and any framework that makes HTTPS calls can integrate directly.
Smart contracts set the limits: per transaction, per day, per counterparty. Each agent operates with its own bearer token and a cumulative fiat spending limit set by the account holder. Cryptographic guardrails, not policy documents. Auditable, tamper-proof, real-time.
Yes. BRRR’s accounting network tracks input/output across multiple agents. Swarms of autonomous actors settle, split, and reconcile without a central treasury manager. Conditional logic, streaming payments, and multi-party splits are all encoded in smart contracts.
The SDK @holyheld/sdk and API are designed for rapid integration. Live demo apps are available for reference. The test environment is accessible immediately with the shared test key. A quickstart guide walks through the full flow from the first API call to completed flow.
Yes. On the SDK side, the $SDKTEST customer executes real on-chain transactions without triggering any fiat settlement, so you can validate the complete flow safely.
Battle-tested. In production for 3+ years across 30+ European countries. Collaboration with Visa on card network integration. Audited, open-source smart contracts.
