Mosta Launches MainUSD: Regulated Stablecoin for AI Agent Workflows

The distinctive angle is native support for agentic commerce. As autonomous AI agents handle procurement, supply-chain management, and automated purchasing, they need a machine-readable financial system. Through MainUSD, companies can issue controlled, automated corporate cards directly to agents connected via the Model Context Protocol (MCP). Those agents can then execute multi-step transactions, optimize outlays, and handle real-time vendor settlements under programmatic guardrails and human oversight.

Mosta operates with named, segregated accounts at Tier-1 partner banks, plus branded invoicing tools with automated reconciliation. MainUSD is designed to comply with the emerging GENIUS Act stablecoin framework as U.S. rules take effect. Brale handles reserve management, compliance, and issuance, letting Mosta clients scale on-chain operations without building that infrastructure from scratch.

“We built Brale to make it easy for companies like Mosta to launch their own stablecoins without having to build reserve management, compliance, and issuance infrastructure from scratch,” said Chase Merlin, head of product at Brale. “The demand for business-grade stablecoin settlement is accelerating, and MainUSD is a strong example of what that looks like in practice.”

The launch adds another regulated dollar token to a market already crowded with USDC, USDT, and bank-issued alternatives. What sets MainUSD apart is its explicit design for AI agent workflows – a use case that most stablecoin issuers have not addressed directly. If autonomous commerce grows as projected, the infrastructure layer that supports it could see disproportionate demand. Mosta is betting that the bottleneck is not technology but integration between stablecoins and corporate treasury systems.
