On October 14, 2026, Polygon Labs announced that it had completed its acquisition of Coinme. The company did not give a completion time or a standalone purchase price in the announcement. The transaction adds a regulated U.S. payments business to Polygon Open Money Stack, the company’s system for accounts, wallets, cross-chain routing, settlement, banking connections and payouts.
Polygon says the acquired business gives it coverage across 48 states through 37 state money transmitter licenses and 11 applicable exemptions. The business is also registered with the Financial Crimes Enforcement Network as a money services business. That coverage is the regulated entry and exit layer for dollars moving through banks, cards or cash deposits before value moves onchain or reaches a recipient.
The announcement names Tazapay, Mesh, Toku and Kira as early adopters. Their uses cover cross-border business payments, account funding, global payroll and access to U.S. dollars. Polygon says Open Money Stack is live now. It does not give transaction volumes, commercial pricing or a schedule for moving each customer from integration to full production.
What Coinme adds to the stack
Open Money Stack already combines accounts and wallets with infrastructure for routing payments across chains and settlement rails that operate around the clock. Polygon says it connects those components to banking and payout infrastructure through one integration. Coinme changes the U.S. side of that arrangement by putting licensed money transmission coverage inside Polygon’s payments business.
For a payments operator, the immediate change is organizational as much as technical. A team building a stablecoin flow can source the account, wallet, routing, settlement, banking and payout components from the same stack. Polygon presents this as an alternative to managing each handoff through a separate provider. The license footprint does not make every feature available everywhere, however. Polygon’s disclaimer says features and use cases remain subject to applicable law and may not be available in every jurisdiction.
The stack is designed to connect money in motion with balances that remain available after a transfer. Polygon describes a flow in which dollars enter through banks, cards or cash deposits, move onchain, and arrive where a recipient can use them. A customer can start with a transfer, then add accounts, balances and payout functions around that transfer.
This arrangement separates the payment path into functions that an operator can inspect. Pay-in methods bring fiat into the system. Wallets hold the resulting balance. Routing infrastructure moves value between chains, while settlement rails complete transfers outside banking hours. Banking and payout connections return value to the local systems a recipient uses. Polygon’s announcement presents these functions as one product stack, but each customer example uses a different subset. Tazapay focuses on conversion and wallets, Mesh on account funding, Toku on payroll payouts, and Kira on banking access.
Coinme’s addition also changes what operators need to diligence. The relevant counterparty is no longer only blockchain infrastructure. A team using the U.S. payment path must also assess the licensed entity, the states covered by licenses or exemptions, the banking partners behind a flow and the availability limits attached to its specific use case. Polygon says users and institutions remain responsible for complying with the rules in their jurisdictions.
How the first customers plan to use it
Tazapay is using Open Money Stack’s on-ramp, off-ramp and wallet infrastructure to connect stablecoins with local currency. Tazapay already serves more than 1,000 enterprises and fintechs across more than 30 countries, using local payment and SWIFT rails. The integration is intended to let its customers receive, hold and pay out funds across markets with fewer intermediaries in each transaction.
Mesh is adding Polygon’s on-ramps to a network that connects more than 300 wallets, exchanges and financial services. Its customers can fund accounts from wallets and exchanges they already use. The operator implication is that a business connected to Mesh can add Polygon’s regulated on-ramp path without building another direct integration for every source account.
Toku is applying the wallet and payout functions to payroll. The company operates in more than 100 countries and handles employment contracts, tax withholding, benefits and local filings. Its planned flow lets workers paid in stablecoins hold earnings in a wallet and convert them to local currency within the same payroll process. Polygon says this work builds on Toku’s stablecoin payroll launch in January.
Kira is using the stack to expand the stablecoin options offered alongside U.S. banking. Kira’s service opens U.S. dollar accounts at multiple banks, supports ACH, Fedwire and FedNow, pays overseas suppliers through SWIFT, and converts between stablecoins and dollars. The company says accounts open within 72 hours after it receives a client’s documents and that 9 of 10 payments pass the first review. Humans approve every decision made through its AI-agent workflow.
What remains unresolved
The four customer examples show distinct routes into the same regulated layer, but the announcement does not say which states rely on exemptions, which banks support each flow or when every integration will handle live customer volume. Those details determine whether a payment operator can use the stack for a specific corridor without retaining another provider.
Polygon also reserves the right to modify, suspend, restrict or discontinue Open Money Stack or any component. Its legal notice identifies technical vulnerabilities, regulatory uncertainty and possible loss of funds as risks associated with blockchain systems and smart contracts. Operators therefore still need contingency paths for account access, conversion and payouts even when the primary flow uses one integration.
The next observable milestone is production use by Tazapay, Mesh, Toku and Kira. Polygon says Open Money Stack is live today, while its announcement leaves each customer’s rollout date and transaction volume unspecified.
