WalletConnect
The QR-code protocol that taught crypto wallets to talk is becoming a payment rail for stores, apps and AI agents. Its advantage is not a new wallet - it is the network already hiding behind hundreds of them.
Fireblocks
Fireblocks began with a $200 million crypto heist and a stubborn question: how do you move digital money without handing attackers the keys? Eight years later, its answer has become an operating system for institutions moving value onchain.
dtcpay
dtcpay is a Singapore-headquartered, regulated payments company that lets merchants, consumers and financial institutions move money in stablecoins as easily as in dollars. Founded in 2019 as Digital Treasures Center by Alice Liu and Band Zhao, it runs a real-time swap engine that converts stablecoins to fiat at the moment of payment, so a shopper can pay in USDC while a merchant is settled in Singapore dollars. The company holds a Major Payment Institution licence from the Monetary Authority of Singapore plus licences and registrations in Hong Kong, Australia, the United States, Canada and a Luxembourg EMI licence covering the European Economic Area. In January 2025 it dropped volatile cryptocurrencies entirely and became stablecoin-only. Its product line spans in-store POS+ terminals, online checkout, payment links, multi-currency wallets, a Visa Infinite "Digital Treasures Card", corporate cards and stablecoin-as-a-service APIs for institutions. dtcpay raised a US$10M Series A led by Vertex Ventures Southeast Asia & India in March 2026, bringing total disclosed funding to roughly US$26.5M.
KAST
KAST is a stablecoin-powered global money app that lets people store, earn, send and spend digital dollars. Founded by former Circle executive Raagulan Pathy and ex-Quona Capital partner Daniel Bertoli, the company issues Visa cards that convert USDC, USDT and other stablecoins into local currency at more than 150 million merchants across 170+ countries. KAST layers yield-bearing vaults, instant transfers, cashback and SOL staking rewards on top of a neobank-style account, positioning itself as a financial platform for globally mobile users and, increasingly, businesses.
Thunes
Thunes is a Singapore-headquartered cross-border payments company that operates a proprietary Direct Global Network connecting businesses to bank accounts, mobile wallets, cards and stablecoin wallets in more than 130 countries and 80-plus currencies. Spun out of TransferTo in 2016 and led by co-founder and CEO Peter De Caluwe, Thunes powers real-time money movement for gig-economy platforms, super-apps, banks, remittance companies and PSPs, backed by its in-house SmartX Treasury System and Fortress Compliance Platform. In 2026 Juniper Research ranked it among the top three cross-border payments leaders alongside Swift and Visa.
Triple-A
Triple-A is a Singapore-based, globally licensed payments institution that lets businesses accept and send money in stablecoins and local currencies without ever holding, converting, or managing crypto themselves. Founded by serial fintech entrepreneur Eric Barbier, it settles merchant payments in fiat (USD, EUR, and 30+ local currencies) with next-day bank settlement, handling custody, conversion, and compliance behind the scenes. It became the first digital-currency payment company licensed by the Monetary Authority of Singapore and serves merchants including Farfetch, Razer, Charles & Keith, Grab, and the Singapore Red Cross.
Wayex
Wayex is a Sydney-based fintech that lets people hold a single US dollar balance, fund it with bank transfers or stablecoins, and spend it worldwide on a Visa card. Founded in 2018 as CryptoSpend by two University of Technology Sydney students, it issued Australia's first crypto-linked Visa card in 2021, rebranded to Wayex in 2024, and in 2025 launched Wayex Global across 160+ countries. The platform supports USDC, USDT, DAI and PYUSD across 10+ blockchains, pays yield on stablecoin balances, and processes conversions in real time at checkout.
Sphere Labs
Sphere Labs is a Boston- and Delaware-based fintech building the payments infrastructure for the stablecoin economy. Founded in 2022 by Arnold Lee and Luigi Charles, the company runs two products: SpherePay, a B2B cross-border payments API that moves money using a 'stablecoin sandwich' - converting local currency into a stablecoin, routing it across borders, then settling into the destination currency in 15-30 minutes; and SphereNet, a 'sovereign-grade' settlement ledger built on the Solana Virtual Machine for regulated financial institutions. Often described as a 'Stripe for crypto,' Sphere pairs developer-friendly APIs and SDKs with embedded compliance to help fintechs, institutions and businesses in emerging markets move value fast, transparently and legally. It raised a $5M strategic round in December 2024 led by Coinbase Ventures and Kraken Ventures.
