Fireblocks launches Liquidity Market for stablecoin trading.

Fireblocks launches Liquidity Market for stablecoin trading. B2C2 and Zodia Markets are providing liquidity at launch, with six additional trading firms expected to join. Get the hottest Fintech Singapore News once a month in your Inbox Fireblocks has launched a trading platform that allows payments companies to compare stablecoin prices from multiple liquidity providers in one place. Fireblocks Liquidity Market enables customers to request quotes from different over-the-counter (OTC) trading desks and execute transactions under existing trading and settlement arrangements. MoneyGram, OpenPayd, Reap, TapTapSend and Zepz have joined as design partners. B2C2 and Zodia Markets are available as liquidity providers, with Cumberland, FalconX, GSR, Hercle, Nonco and Wintermute expected to follow. OTC and trading firms transferred nearly US$50 billion in stablecoins to payments companies and financial institutions through the Fireblocks Network over the past 12 months. However, sourcing liquidity still requires businesses to deal with trading desks individually. "Payments companies already hold their stablecoin treasury on Fireblocks, and most of the desks they trade with do too. The one step still happening outside the platform was the price discovery itself, and execution, negotiated desk by desk over chat and email. Bringing it inside means the desks they trust can all bid for every trade, under the same controls and policies that govern the rest of their treasury." said Ran Goldi, Chief Payments & Network Officer at Fireblocks. The platform consolidates credit information and balances while enforcing trading limits and approvals through Fireblocks' Policy Engine. Fireblocks does not charge a spread or take custody during conversion. Customers settle transactions directly with liquidity providers. Liquidity Market is available to Fireblocks customers and supports major stablecoins against the US dollar, euro, British pound and other G10 currencies.

Euronet and Fireblocks launch stablecoin-funded card issuing for banks and fintechs

Euronet and Fireblocks have expanded their partnership to let banks, fintechs and other financial institutions launch stablecoin-funded card programs on Euronet's Ren and CoreCard issuing platforms. Fireblocks supplies the embedded wallets that hold and move the stablecoin balances. Each cardholder gets a wallet at onboarding, and fiat deposits convert to stablecoin before they are credited. Merchants still receive local currency. Euronet plans to offer the service as a white-label product that clients can embed in their own banking or wallet apps. The companies began working together in October 2025 on partner settlement and pre-funding. Demand is growing: more than 160 stablecoin-linked card programs were live on the Visa network in its fiscal second quarter of 2026, with payment volume up nearly 200% year over year.

Euronet and Fireblocks launch a new stablecoin-funded card solution, simplifying how consumers spend digital assets at the point of sale. Curated by Financing Your Way from original reporting by Finextra - Lending. Summary is AI-assisted and editorially reviewed - see its editorial standards. This partnership between Euronet and Fireblocks introduces a way for businesses to issue payment cards funded by stablecoins (digital assets pegged to a currency like the US Dollar). For retailers and operators, this means the infrastructure for 'crypto-to-fiat' spending is becoming more mainstream and accessible. Instead of waiting for traditional bank transfers or dealing with volatile assets, this technology allows customers to spend their digital holdings directly at the point of sale just like a traditional debit or credit card. For your business, this signals a shift in how consumers may want to access their liquidity. While it feels like a niche financial product now, the backend integration provided by Euronet simplifies the process for merchants to accept these funds without needing to manage the underlying blockchain technology themselves. As consumer interest in digital assets persists, having a payment ecosystem that bridges the gap between digital wallets and traditional merchant terminals becomes a competitive advantage. It offers a glimpse into a future where 'financing' your purchases might involve drawing from a digital asset pool rather than a traditional line of credit. Who else is covering this

Fireblocks launches stablecoin liquidity market with multi-desk OTC quotes for payments firms

Fireblocks has launched Liquidity Market, a trading environment that lets payments companies and other businesses compare stablecoin quotes from multiple over-the-counter (OTC) desks and trade without leaving the platform. Fireblocks says it takes no spread. MoneyGram, OpenPayd, Reap, TapTapSend, and Zepz are design partners. B2C2 and Zodia Markets are live as liquidity providers, with Cumberland, FalconX, GSR, Hercle, Nonco, and Wintermute to follow. Over the past 12 months, OTC and trading firms moved nearly $50 billion in stablecoins to payments companies, fintechs, and banks across the Fireblocks Network. Sourcing that liquidity is still largely manual, handled desk by desk. Customers keep their existing credit and settlement terms, and settle directly with the provider. Liquidity Market is available now to Fireblocks customers globally.

Fireblocks launches Liquidity Market, bringing streaming OTC pricing into stablecoin payments. Staff October 15, 2026 4 minutes read MoneyGram, OpenPayd, Reap, TapTapSend, and Zepz joined as design partners NEW YORK, Oct. 15, 2026 /PRNewswire/ - Fireblocks, the enterprise platform securing $16 trillion in digital asset transactions, today launched Fireblocks Liquidity Market, bringing multiple OTC liquidity providers into a single trading environment for payments companies and other businesses buying and selling stablecoins. Customers can request quotes from multiple desks, compare them side by side, and execute leveraging their existing relationships, credit terms, and settlement arrangements with each provider. Payments companies can now compare quotes from multiple OTC desks and trade stablecoins without leaving Fireblocks. MoneyGram, OpenPayd, Reap, TapTapSend, and Zepz have joined as design partners. B2C2 and Zodia Markets are live as liquidity providers at launch, with Cumberland, FalconX, GSR, Hercle, Nonco and Wintermute to quickly follow. Over the past 12 months, OTC and trading firms moved nearly $50 billion in stablecoins to payments companies, fintechs and banks across the Fireblocks Network. Sourcing that liquidity remains largely manual, handled with each desk separately through its own portal, credentials and integration. Quotes often expire before they can be compared, and teams reconcile credit limits and balances by hand. "Payments companies already hold their stablecoin treasury on Fireblocks, and most of the desks they trade with do too," said Ran Goldi, Chief Payments & Network Officer at Fireblocks. "The one step still happening outside the platform was the price discovery itself, and execution, negotiated desk by desk over chat and email. Bringing it inside means the desks they trust can all bid for every trade, under the same controls and policies that govern the rest of their treasury." Fireblocks Liquidity Market gives teams a consolidated view of available credit, margin requirements and balances across every connected desk. Trades execute through the Fireblocks Console or API, and each fill is recorded against its originating quote. Fireblocks does not take any spread. At launch, Liquidity Market supports all major stablecoins against USD, EUR, GBP, and other G10 currencies. Outside of Fireblocks, each desk grants trading permissions on its own platform, with nothing enforcing them across providers. In Liquidity Market, the Fireblocks Policy Engine enforces trading limits and execution permissions across every connected desk, and connecting an account or executing an order requires quorum approval. Fireblocks does not sit in the flow of funds or take custody at conversion. Settlement happens directly between the customer and the liquidity provider. "Payments companies have become some of the most consistent stablecoin volume in the market, and they want to trade where their treasury already sits," said Nick Philpott, co-founder of Zodia Markets. "Now that Zodia Markets is available inside Fireblocks, they can see our pricing and trade without leaving their existing workflow." "At our scale, depth of liquidity is very important, particularly in markets that aren't deeply liquid in the traditional sense. Being able to draw on multiple providers at once, rather than relying on a single desk, is how you build resilience into the hard to reach corridors." said Anthony Silva, SVP, Treasurer, at MoneyGram. "Every new dealer used to mean a procurement cycle and an integration project before we saw a single quote," said Richard Usher, Director of Trading at OpenPayd. When a new provider joins Liquidity Market, it appears alongside the desks Crypto Coins already trade with. That changes how many counterparties a desk running at its pace can keep in the mix." Liquidity Market is available now to Fireblocks customers globally, with additional liquidity providers added on a rolling basis.
