How Arc Supports Treasury Management | Arc Blueprints

Arc¹  is a stablecoin-native, Layer-1 (L1) blockchain built to support real economic activity onchain. With deterministic finality, fiat-denominated gas fees, and compliance-ready programmability, Arc is designed to support the most foundational functions in finance, starting with how companies manage their cash.

Treasury management is one of the most critical and operationally demanding functions in finance, and is projected to grow rapidly over the next several years with a 13.90% CAGR. Yet even sophisticated treasury teams still rely on fragmented banking infrastructure, batch settlement, and manual reconciliation. Those gaps are becoming harder to justify as businesses (and their customers) increasingly expect real-time visibility and always-on operations.

This post explores how Arc, the Economic OS for the internet, enables a new class of real-time, programmable treasury management for startups and enterprises that brings control, speed, and automation to global liquidity management.

The challenges of traditional treasury infrastructure

Corporate treasuries today operate across a patchwork of banks, systems, and jurisdictions. Basic questions like “Where is our cash right now?” or “How quickly can we fund this account?” can be surprisingly hard to answer because cash positions, reporting, and approval controls are fragmented across various banks, ERPs/TMS platforms, and manual workflows.

Under this system, even routing operations are often slow and manual:

• Cash visibility updates in batches rather than continuously
• Reconciliation can require multiple teams and systems
• Cash sweeps, payouts, and approvals depend on cut-off times and intermediaries

For global organizations, complexity multiplies. Intercompany transfers can take days, vendor payments may settle slowly across borders, and FX introduces additional friction and risk. To compensate, teams often keep buffers across accounts and geographies — capital that is “available,” but not efficiently deployable.

In practice, this makes treasury management reactive. Cash sits idle because moving it is slow, visibility is incomplete, and automation is constrained by legacy rails.

What blockchain changes for treasury management

Blockchain infrastructure offers a different operating model: a unified ledger for money movement that is always-on, programmable, and auditable in real time. Instead of stitching together reports across institutions, treasury teams can manage capital with a consistent system of record and automate what used to require manual intervention.

This shift enables treasurers to move from operational bottlenecks to policy-driven workflows. Treasury becomes less about chasing spreadsheets and more about executing strategy: allocating liquidity, enforcing controls, and responding quickly to needs across the business.

The table below highlights some of the key differences between traditional and onchain treasury infrastructure:

Making onchain treasury work in practice comes down to settlement certainty, cost predictability, and controllable privacy — areas Arc was built to address.

How Arc supports onchain treasury management

Arc’s unique design is critical to this shift from offchain to onchain treasury management. It’s built from the ground up to support programmable money movement and provides a stable, composable foundation for treasury applications. Three Arc capabilities translate directly into better treasury operations:

• Deterministic, sub-second finality helps cash positions update instantly, enabling real-time funding and liquidity decisions.
• Fiat-denominated gas fees provide predictable, budgetable costs for high-volume treasury operations.
• Opt-in privacy can help protect sensitive details (like vendor relationships, internal transfer amounts, and entity activity) while preserving auditability and compliance controls.

Together, these features make Arc a strong foundation for always-on treasury: real-time visibility across entities, instant intercompany movement, programmable disbursements, and policy-based cash deployment.

Below are three common treasury workflows Arc can support, from creating infrastructure for moving funds between entities to automating disbursements and putting idle cash to work.

Multi-entity and cross-currency treasury operations

With Arc, companies can program moving funds instantly between entities and jurisdictions. Intercompany transfers settle in under a second, with balances updating in real time. Intercompany transfers can settle in under a second without banking cut-off times or delayed settlement.

Arc also supports stablecoin-to-stablecoin conversion (for example, USDC² to EURC³) through onchain infrastructure, enabling multi-currency treasury flows without relying entirely on traditional FX rails. Subsidiaries can transact in local denominations while headquarters consolidates liquidity, using smart contracts to automate funding, rebalancing, and policy enforcement.

Circle’s own treasury team has already proven what this looks like in production. By using stablecoins and onchain infrastructure, Circle consolidated global intercompany operations into just two smart contract-based treasury accounts. This configuration allows their finance team to initiate transfers between multiple legal entities across regions 24/7 without relying on third parties.

Automated disbursements and programmable workflows

Arc enables treasury teams to automate workflows that often require manual processing today. Smart contracts can be designed to:

• Execute scheduled payroll or recurring payouts
• Settle invoices automatically after approval
• Trigger cash sweeps when balances exceed thresholds
• Enforce multi-approver policies for high-value transfers

Because Arc features deterministic finality and stablecoin-denominated execution, payments can be predictable in cost, final once executed, and traceable in real time. This lets teams codify treasury policies (e.g., guardrails that only allow vendor payouts during specific windows or multi-sig approval for large disbursements) directly into workflows, reducing operational load while improving control.

This level of programmability unlocks a new approach to treasury strategy. One that is proactive, not reactive, and custom to each business's cash operations.

Onchain yield strategies for idle cash

Onchain treasury also expands how teams can manage idle cash. Instead of sitting in low-yield accounts by default, liquidity can be allocated into tokenized yield-bearing instruments (such as short-term T-bill strategies, regulated lending pools, or yield-bearing stablecoins) based on internal policy and risk preferences.

Because these assets are programmable and composable, strategies can be automated via smart contracts. Treasury teams can define allocation rules, thresholds, and redemption conditions to maintain capital efficiency. Whether it’s parking idle cash for 72 hours in a T-bill fund or lending to an approved pool with real-time reporting, Arc enables these strategies to be executed programmatically while maintaining full control and visibility.

Build on Arc and reinvent treasury for the internet economy

Arc gives teams the tools to move beyond spreadsheets, batch wires, and manual reconciliation into a new era of programmable capital operations. One where treasurers can manage cash with more agility, visibility, and confidence than ever before. Treasury systems built on Arc respond in real time to changing capital needs across currencies, jurisdictions, and counterparties with a stablecoin-native foundation and sub-second, deterministic finality.
