Why keep patching the card scheme? Wallets replace accounts. Smart contracts replace protocols + fee splits. Stablecoins replace closed bank ledgers. OpenPasskey is rebuilding the retail rail from the tap moment up.

🛍️ What's the future of crypto retail payments? @flexaHQ CEO @dannymccb says It's not $BTC or stablecoins. He predicts the "underdog" winner will be loyalty points and merchant tokens. He explains why "folks are still spending Bitcoin more than anything else," but that's

Trying to optimize stablecoins by running them solely on legacy fiat rails is a dead end. It just adds extra steps, costs, and friction through wrapping and on/off-ramps. 🐌 To unlock their true potential for speed and efficiency, stablecoins need their own dedicated native rails
Stablecoins lost to fiat. In speed and in cost. Here's a good example on why Stablecoin is too hyped. I had to pay rent, so I tested both rails instead of repeating slogans. Transfer w/@Wise (USD → EUR): Sent $3,600 Fee (included): $10.97 → converts $3,589.03 FX rate: 0.8527

@ShanAggarwal When payments become the on-chain bus, loyalty, marketing, and financing plug in on the same rail. Smart contracts encode the rules and fee splits, routing value back to the participants who create it. Can @base get us there? @ShanAggarwal @sfrankel9 @jessepollak

@jessepollak @base @Shopify In the US alone, merchants paid a staggering US$ 125.87 billion in in-person card payment fees in 2024. If we removed banks (issuers), networks like Visa and older acquirers, that money could be more effectively distributed.

"Stablecoins don’t win on fees anymore. They win on distribution." What’s the real bottleneck for stablecoin payments in the real world? A) Fiat conversion (AUD↔stable) B) Merchant acceptance / POS C) UX + habit formation D) Privacy + compliance

100 % Agree. That's why we are building an on-chain card scheme for crypto, providing an alternative rail for merchants and consumers who care about ownership, fees, settlement time, UX and privacy.
Hot take: If your crypto card settles on Visa or Mastercard, it’s not a real crypto card...

The harsh truth about credit card rewards: Small businesses foot the bill for fees, but it's the banks that cash in on customer loyalty.

I’m pretty good to be one of the 50 finalists from Batches 002!
Here’s what happened in November @Coinbase: • Introduced ETH-backed loans in the U.S. (ex-NY), allowing users to borrow USDC against their Ethereum while retaining ownership. • Acquired @VECTORDOTFUN, an onchain trading platform built on @Solana, to strengthen Coinbase’s

We’re building OpenPasskey—the card scheme for crypto, like Visa is for fiat. We start in one vertical – cafés – by fixing offline loyalty with an all-in-one NFC terminal and Apple/Google Wallet cards; over time the same hardware and wallet identity give merchants a clean path

local stablecoins are the future👇 Payments are the bus that connects every business system. Once payments really penetrate retail, blockchains stop being just payment rails and become the integration layer for how commerce fits together. Local-currency stablecoins are a must

The fatal flaw of Visa/Mastercard isn't fees—it's that they are Information Silos. They know the 'Who' and 'How Much', but lose the 'What' (SKU and ….). Crypto restores the link between Money and Data. That’s the real alpha.
1/5 🧵 Unpopular opinion: The biggest opportunity in crypto payments isn't "uncensorable money" or "lower fees." It's Integration. Here is why the next payment giant won't be a bank, but a protocol. 👇

5/5 🚀 The 100x Efficiency: Why would a merchant switch to crypto? Not to "accept USDC." They switch to get rid of the 5 other SaaS tools they hate. We aren't building a new way to pay. We are building a new way to settle business logic. Payment is just the carrier.

4/5 ⚡️ The Crypto "Unfair Advantage": True crypto payments are Programmable Money + Programmable Data. On-chain, we don't just move value; we move context. One tap can be the Payment AND the Membership AND the Receipt. All in a single atomic transaction.

3/5 🧱 This creates friction. Loyalty points? Separate app. Receipts? Paper waste or email spam. Data analytics? Fragmented. Merchants are drowning in disconnected systems because the payment layer is "dumb."

2/5 💳 The Problem: Visa & Mastercard are information silos. Look at your bank statement: "Starbucks - $5.00." That's it. They tell you how much you spent, but they have no idea what you bought (SKU). In traditional rails, the Money Flow is severed from the Information Flow.
