Key Takeaways:
Polygon's Open Money Stack collapses fiat on-ramps, stablecoin transfers and bank off-ramps into a single API, aiming to settle payments in seconds rather than days.
Polygon launched the Open Money Stack (OMS) in technical preview on June 4, a unified application programming interface designed to move money globally using stablecoins. The stack integrates cash deposits, corporate bank accounts, custodial wallets and stablecoin transfers under one set of endpoints, with early access granted to a select group of partners.
"Moving money across borders today means navigating a system built on 50-year-old infrastructure — SWIFT, correspondent banking and legacy payment rails that are slow, expensive and opaque," Sandeep Nailwal, CEO at Polygon Foundation, said. "We built OMS on blockchain infrastructure because payments should work more like the internet: fast, global and transparent by default."
The core loop converts fiat deposits into USDC or USDT on the Polygon chain, executes transfers in seconds at fractions of a cent, and enables withdrawal via bank rails or external wallets. Cash ramps operate across 48 US states through a partnership with Coinme, while business clients receive virtual bank accounts with ACH, Fedwire and real-time payment support. Polygon's chain has processed more than $2.6 trillion in stablecoin transfer volume over six years of production.
OMS enters a market where most stablecoin infrastructure providers act as orchestrators, routing between third-party ramps, wallets and chains. Polygon built and operates the full vertical — wallets, ramps, chain, cross-chain routing and settlement — meaning clients deal with one counterparty and one service-level agreement. The company cited a payroll use case in which 200 contractor payments settled in seconds for less than one cent per transaction, compared with one to three business days on traditional rails.
What's live vs. what's coming
The technical preview includes cash ramps, bank ramps, custodial wallets (USDC and USDT on Polygon), stablecoin transfers between wallets, external wallet routing, and a full API with webhooks, role-based access control and single sign-on. A dashboard lets teams manage balances, track transactions, generate API keys and set permissions.
On the roadmap: embedded wallets, token swaps, cross-chain bridges, personal bank off-ramps and a regulatory compliance dashboard. The company said it is onboarding teams in waves and prioritizing businesses actively building payments products.
Why it matters
The global payments industry processes more than $150 trillion annually, with cross-border flows accounting for roughly $40 trillion, according to McKinsey. Traditional correspondent banking takes one to five days and costs 3% to 7% in fees and foreign-exchange spreads. By settling on Polygon in seconds at near-zero cost, OMS targets the portion of that volume that can shift to stablecoin rails — payroll, remittances, business-to-business payables and marketplace settlements.
The broader infrastructure behind OMS is already live: Polygon's embedded wallet product, the chain development kit for launching blockchains with native liquidity access, and Polygon Trails for cross-chain transactions. The company is accepting early access requests through its website.
