The biggest winner of the neobank takeover is @raincards. From $100 in processed volume in April 2023 to $300,000,000 in April 2026. One of the biggest & underrated growth stories in crypto.

Public blockchains are great for auditability but different use cases need different levels of confidentiality. Now Rain customers have a choice. Today we're announcing our integration with @payy_link bringing configurable on-chain privacy to Rain's stablecoin card programs. Payy Network uses ZK cryptography to keep transaction details private by default, with selective disclosure for compliance and transaction monitoring. @sidgandhi_xyz @calummoore and the @payy_link team were early Rain customers and proved out the tech and demand themselves. Now we're making it available to everyone else.

Last year we proved onchain privacy can work for 80K KYC’d users with the Payy Visa Card. Now for the first time we’re bringing that capability to EVERY Rain card program. That’s millions of cards and billions of dollars in real world stablecoin spending. Incredible push by both teams on this and we couldn’t be more excited.

I chose @FirstMarkCap to lead our recent round because they have the confidence and conviction to back and grow generational startups across every vertical. Every company using ACH and SWIFT today, will be defaulting to stablecoins in a few years. But what blockchain will they use? They will choose one that is built from the ground up for safety, security and privacy. These principles have motivated me across my career starting with my time at Apple. Now we’ve instilled this philosophy into Payy’s products and technology. Some of the largest stablecoin infra providers are partnering with us to finally enable default confidential payments on EVM — never before achieved. I’m incredibly excited for this next chapter of Payy supported by @FirstMarkCap, @robotventures, @dba_xyz and all our other investors.

FirstMark backed Shopify before anyone bought anything online. Discord before anyone gamed with strangers. Airbnb before anyone turned their home into a hotel. Now they're betting privacy onchain is next. We raised $6M led by @FirstMarkCap to make private transactions the default. Joined by @dba_xyz & @robotventures. Investors who understand that privacy isn’t a feature, it's the foundation.

Stablecoins are emerging as the future of payments, but imagine your bank account was public.... That’s basically how stablecoins work today. @sidgandhi_xyz @calummoore are fixing that with @payy_link , all the benefits of on chain payments with the benefits of institutional grade privacy. Already live, global, real usage. Proud to lead their $6M seed round alongside our friends at @robotventures and @6thManVentures

Payy is built on Ethereum. @payy_link is a privacy-first stablecoin chain designed so your transactions aren’t exposed to the world. It brings programmable payments to Ethereum, without sacrificing privacy by default.
