Polygon Expands Open Money Stack to Solana to Route Payments from Banks to Banks
Key Facts
Polygon announced on October 29, 2026, that Open Money Stack is available to businesses operating on Solana, allowing them to manage an end-to-end stablecoin payment flow that starts with a bank deposit and ends with a bank payout. The company said the platform connects bank money and stablecoin balances along this flow, enabling businesses to keep Solana at the center of their products while adding the infrastructure needed to move money in everyday use. Polygon said these businesses can "keep the network their users know and add the financial infrastructure that makes the product work in the real world." The announcement expands the platform from serving businesses on the Polygon network to supporting products that operate on other networks. The infrastructure aims to bring deposits, conversion, custody, routing and payouts together in one experience.
Polygon said its options for receiving funds include bank transfers, cards, cash and cryptocurrencies. After receipt, fiat currencies can be converted into digital assets on Solana, and funds can be held in custodial wallets or wallets embedded in apps. The platform supports routing USDC, USDT, PYUSD, SOL and wrapped SOL between Solana, TRON and EVM networks in a single transaction. Its functions also include converting funds back into fiat currencies, then paying them out to bank accounts, cards, cash or wallets. This allows businesses to integrate payment stages connected to users and banks with digital-asset flows across multiple networks, according to the company’s description of the service.
Polygon says Solana moves more than $2 trillion in stablecoins each quarter, pointing to the scale of activity the platform aims to connect with. The Solana Foundation had said the network surpassed $5 trillion in stablecoin transfers during 2026 through September 30. This figure measures transfers of stable assets, not their trading in markets, which differs from the description in the initial version of the story. On the Polygon network, cumulative stablecoin transfers exceeded $3 trillion from September 2020 through September 29, 2026. The periods are not comparable: Solana’s figure covers the year through September, while Polygon’s is cumulative since 2020.
Polygon said stablecoin transfers on its network reached $933 billion in 2025, compared with $276 billion in 2024, while volume reached $741 billion during 2026 through September 29. These figures put annual and cumulative transfer activity in the context of the platform’s expanding use, but on their own they do not measure the payment volumes Open Money Stack will process on Solana. In September, stablecoin supply on Solana reached a record $17.51 billion, according to the Solana Foundation. The number of daily active stablecoin addresses also reached 888,000 during the month, up 269% from 333,000 in September 2025. These indicators show the breadth of activity on the network, alongside the transfer volume Polygon cited to explain its support.
The Solana Foundation said 6.2 million people transacted in USDC on the network over 30 days, representing 42% of USDC senders across all networks and 2.5 times the number of senders on the next-largest network. In September, completed non-vote transactions exceeded 3.18 billion, up 8.3% from August, while the third-quarter total reached 8.78 billion transactions. Polygon announced in August that its Trails routes allow SOL, wrapped SOL, USDC, USDT and PYUSD to be transferred between Solana and more than 20 EVM networks. In September, the company described Open Money Stack as a single API connecting wallets and deposit, withdrawal and settlement routes, with functions being rolled out gradually. Making the platform available to businesses on Solana adds a bank-payment route to that multi-network infrastructure.
The expansion of Open Money Stack to TRON was announced on October 8, three weeks before the announcement of Solana support. On October 14, Polygon announced it had completed its acquisition of Coinme, saying the deal adds regulated money-movement operations in the United States. The company said its U.S. coverage includes 48 states, through 37 money transmitter licenses and 11 applicable exemptions, and that it is registered with FinCEN as a money services business. It also said Tazapay, Mesh, Toku and Kira are among the platform’s early adopters. The expansion brings together support for additional networks, regulatory infrastructure and early customers, according to Polygon’s announcements during October.
Polygon announced on October 12 a feature for running automated stablecoin payouts, allowing recipients, budgets and execution windows to be set in advance, with each payout checked against its scope, spending limit and expiration. On October 21, it unveiled spending controls for agent-executed payments, including a defined budget, approved actions and an expiration date. The company says teams can use specific parts of the platform, such as wallets, a compliance provider or a ledger, or run the entire flow through a single product experience. Polygon said Solana would not be the last addition and that it would continue expanding Open Money Stack support to other networks. The company did not specify in its announcement when the next networks would be added.
