In 2021, friends at @opensea told me to move into crypto; it’s been a fun 5 years since. I’ve launched: NFT portfolio management, E2EE file storage, intent orchestration @TrailsHQ, and Open Money Stack @0xPolygon. My passion: accelerating crypto adoption through lovable UX.
If you see this tweet, this is your sign to remember why you got into crypto.

We have waited almost a month for the @tempo team to merge a PR so that we can integrate Trails with Tempo and offer their users and our customers a better cross-chain experience. Trails is built to make it as easy as possible to bring assets to chains and move money between them, and given that Tempo launched recently, it needs assets on the chain. I'm surprised this has been such a long process. If anyone has a connection to facilitate this PR being merged, then please let me know. So far we've been pinging @gakonst and @liamihorne unsuccessfully.

$13. The average cost to send $200 from the US to Mexico. We mapped nine companies moving the same money on stablecoin rails for under 1% in fees. The companies, the corridors, the economics. 📄 Download the free LATAM payments report: share-eu1.hsforms.com/2gtNXM…

As a growth PM who is fortune to work with a talented designer (AI could never: IA, user research, comp analysis, mood boards, nomenclature, DesSys, reusable components, progressive disclosure) — hard agree. Design is more necessary than ever.

When it comes to moving money, the method matters. It's not our first trillion.

CDP 🤝 Polygon
Excited to announce that the Coinbase x402 Facilitator officially supports @0xPolygon. 🚀 This adds to our Base and Solana support, so AI agents can pay for APIs, data, inference, and more across all three ecosystems. The agentic economy is going multichain! 🟣

Mastercard's Crypto Partner Program is live, connecting onchain infrastructure to global payments. Polygon is helping shape that ecosystem, backed by trillions in onchain stablecoin volume and six years of production infrastructure. For Polygon, this program means bringing our onchain payments infrastructure closer to Mastercard's global network. We're connecting with more enterprises, banks, and merchants, so digital assets work for real people, at global scale. Proud to join @Mastercard in turning onchain innovation into trusted, everyday payments.

Polygon tokenomics changed dramatically. For most of 2025 the network generated around 20–30–50k POL per day. Now it’s closer to: • ~2M POL per day • ~50M POL per month And all of it goes back into the ecosystem: • burned • paid to validators (soon to stakers) • protocol rebates for direct incentives This is what sustainable tokenomics looks like. But remember: token data ≠ market data. Price moves when buyers appear, not just when tokenomics looks good.

Rare, special, legit: $2 bills, and $2 trillion of payments on Polygon.
$2.4 trillion is more than the GDP of Brazil. It’s larger than the entire market cap of the S&P 500 healthcare sector. It’s roughly what the U.S. federal government collects in individual income tax in a year. That’s how much value has settled through Polygon’s network in stablecoin transfer volume.
