How Crossmint Supports Stablecoin Apps and the Agentic Economy on Arc

Most teams building with stablecoins don’t want to become infrastructure companies. They want to ship a product that offers benefits like fast remittances, simple checkout, dollar-denominated accounts that work across borders, or agents that can complete purchases autonomously within defined controls. But before their first customer can transact, they may need to integrate wallets, key management, on/offramps, compliance screening, multiple blockchains, and financial products.

Each component may come from a different provider, leaving it up to the team to create a coherent customer experience. Crossmint was built to solve that fragmentation. Its core principle is that onchain products should feel like modern fintech products.

Crossmint provides an all-in-one platform spanning wallets, money movement, compliance tooling, embedded finance, and infrastructure for AI agents. As an Arc partner, Crossmint is bringing that comprehensive approach to a stablecoin-native environment built for payments, financial applications, and agentic economic activity.

How Crossmint evolved into a full-stack stablecoin platform

Crossmint began with a familiar blockchain problem. Co-founders Rodri Fernández Touza and Alfonso Gómez-Jordana Mañas were experimenting with digital assets in 2021 when they saw how difficult it was for a person to transact. A customer might need to create a wallet, secure a recovery phrase, pass identity checks, acquire tokens, and obtain a second token for gas fees.

Their initial answer was a checkout that let people use familiar payment methods (e.g., Apple Pay, Google Pay, credit cards) without needing to understand the infrastructure beneath the experience. 

Today, Crossmint offers embedded and treasury wallets, on/offramps, stablecoin payouts, compliance workflows, and connectors for users to access yield, tokenized assets, DeFi, and more. These modules can be packaged for remittances, payroll, marketplaces, neobanks, and agentic economic activity. Instead of spending time coordinating vendors, a team can start with an integrated stack designed around the product it wants to launch.

Compliance tooling built into money movement

Wallets and payments can involve licensing, identity, transaction monitoring, and other compliance requirements. Crossmint invested in licensing and compliance early, based on the view that stablecoins could only reach mainstream use if these responsibilities were built into the infrastructure.

Supported money movement flows can therefore include relevant checks rather than leaving developers to coordinate separate compliance providers. That consolidation can shorten time to market: MoneyGram, for example, used Crossmint’s infrastructure to bring a stablecoin-powered remittance experience to production in roughly two months — a timeline that reflects how much integration work the platform handles out of the box.

How USDC, CCTP, and Arc support Crossmint’s platform

Crossmint’s work with Circle spans three connected layers. The first is stablecoins like USDC, used for onramps, payouts, treasury operations, remittances, and settlement — the programmable money underneath a familiar financial experience.

The second is Cross-Chain Transfer Protocol (CCTP), which moves native USDC between supported blockchains without wrapping or bridging. It helps Crossmint create smoother multichain experiences while connecting Arc to the broader USDC ecosystem.

The third is Arc itself. Crossmint is preparing its technology to support developers building on Arc. Both platforms focus on fintechs and enterprises that value simple experiences, reliable settlement, privacy, compliance, and scale. Arc’s stablecoin-native design can reduce friction that Crossmint would otherwise need to abstract away at the application layer.

USDC-denominated gas

On many networks, someone spending stablecoins also needs a separate native token for transaction fees — another balance to acquire, manage, and explain. On Arc, gas is paid in USDC. Products can be designed around a dollar-denominated asset without introducing an unrelated token into the user journey, supporting the goal of making blockchain mechanics disappear into the background.

Deterministic finality

Payments and automated workflows need a clear answer: did the transaction settle? Arc provides sub-second deterministic finality. That matters for checkout and software that must decide what to do next. An agent making a purchase or an application updating a balance needs to know when it can safely continue.

Privacy for commercial use

Public transaction histories can expose suppliers, transaction sizes, treasury activity, or a user’s broader wallet history. Crossmint has identified privacy as an important enterprise requirement, making Arc’s planned approach to configurable privacy relevant to the applications it helps companies build.

Building where stablecoins solve visible problems

Crossmint is seeing strong adoption where existing financial infrastructure creates the most friction. Across many emerging markets, users face depreciating currencies, costly transfers, and limited access to US dollars.

Stablecoin-native apps can offer dollar balances, remittances, cards, investment products, and international payments through familiar interfaces. Crossmint sees remittances and cross-border payments as a leading category, followed by stablecoin-native neobanks, global payroll, and cross-border marketplaces.

Making onchain value useful

Getting money onchain is only part of the challenge. Keeping it there requires practical ways to use it. If customers must offramp before every purchase, a stablecoin remains a temporary transfer mechanism.

Merchant acceptance, QR payments, online checkout, and debit cards can help bridge that gap. Embedded finance gives users another reason to retain balances by letting them save, invest, transfer, and spend within one application. Crossmint supplies the product layer; Arc provides a predictable environment for the transactions underneath.

Giving AI agents the ability to transact

Crossmint is extending this infrastructure to software. AI agents can already research, write code, and complete complex tasks. To become economic actors, they need to hold funds, make purchases, pay for services, and operate within clear controls.

Agentic commerce

For transactional use cases (e.g., buying a flight below a set price, ordering workplace supplies, paying per call for APIs and data, or completing procurement within company policies), Crossmint gives agents access to wallets, stablecoin payments, cards, and purchasing infrastructure through APIs. The goal is to let software interpret intent and complete the economic action that follows.

Agentic finance

For financial management use cases (e.g., treasury management, investing, yield, and portfolio rebalancing), agents need tighter controls because mistakes can be costly. Crossmint’s smart-wallet architecture supports transaction limits, approved destinations, signer policies, and gas sponsorship. Arc complements those controls with USDC-denominated execution and deterministic settlement, so agents can participate in financial workflows within boundaries defined by a user or business.

What Crossmint and Arc mean for builders

The next generation of onchain products will be judged like any financial product: Does it solve a real problem, feel intuitive, and scale responsibly? Crossmint addresses those questions at the product layer; Arc addresses them at the execution layer.

Together on Arc, they can support embedded wallets, fiat and stablecoin access, crosschain USDC transfers, integrated compliance workflows, predictable gas, fast settlement, and programmable infrastructure for agents. With Crossmint on Arc, builders can reduce the work involved in stitching together separate wallet providers and compliance vendors, gas token management, and manage settlement finality.

The value of the infrastructure is measured by what it enables: fast remittances, simple checkout, financial accounts that work across borders, and agents that can complete purchases safely and autonomously within defined controls.
