SPCX has landed on MetaMask. 🚀 Trade SPCX perps up to 10x leverage or swap into tokenized stock.

AMP on @arc this is looking good than most people think. visionaries 👀 @bobbilee @samconnerone @silencexlm

Circle Research introduces Arc Multi-Proposer Protocol (AMP), a new approach to block building. AMP introduces proposers that bundle user transactions into payloads and broadcast them directly to validators. The result: → Bounded inclusion → Fixed ordering → Application-aligned order flow For financial applications, block construction matters. Predictable settlement needs predictable transaction handling. circle.com/blog/amp-rethinki…

Neobanks on @base turn those phones into dollar access, cheaper global transfers, and yield on idle balances

The internet had its architects. They built before it was obvious…. Before it was fast…. Before it was normal…. Before the world even understood what they had in front of them…. Every era needs people willing to see first…. This one needs us… Architects

Today we published the detailed design for Arc’s upcoming privacy infrastructure. It is a major step forward in building the Internet financial system in a way that works for people, households, major, corporations, and financial institutions. We’re excited to share this with the world and ultimately bring this onchain on @arc

Something that got missed in the noise last week: Coinbase got approved to offer true global crypto perps in the US. This took many years of work, and we're the first to offer this global liquidity to US users. Backstory: For many years crypto trading has been moving offshore because the US didn't have clear rules, and perpetual futures were a superior product that traders wanted but it wasn't allowed in the US. If we're being honest, probably ~half of all perpetual futures volume was Americans using offshore products via VPN with loose KYC controls (an open secret in the industry). Penalties for this were rarely, if ever, enforced, which as you can imagine, was frustrating for us as an American company following the rules. Others set up offshore entities and found ways around it. After dozens of personal visits to DC, and many more from our policy team, I'm really proud we finally got approval to give US users access to true, global perpetual futures. This is important because we'll now see pooled global liquidity in perpetual futures, with the US and international markets being connected instead of fragmented. Coinbase is strongest in the US, and the US is the largest market for trading, so there is now a chance to build a global network effect around liquidity. And US traders can now use these products in a compliant way with a US company, which hopefully provides greater customer protection. Major credit to Chair Selig and Atkins on recognizing the importance of this for US capital markets. And we will keep working to update the system in a compliant way, and to be the best place you can trade.

Four new providers just joined MetaMask Swaps. 👀 @PancakeSwap, @CoWSwap, @Uniswap, and @Titan_Exchange are providing more competition across your quotes, which means better rates when you swap.

Base is 𝘵𝘩𝘦 chain for payments Here’s why: - Deep liquidity across 25 stablecoins - Sub-second and sub-cent settlement - 90% of agentic transaction volume - Handling $4T in monthly stablecoin volume - Fully integrated into Coinbase Payments If you need even more proof ↓

Agents can handle your travel now too @travalacom’s x402 integration on Base lets AI autonomously book hotels Book across 2.2M hotels with Travala's MCP

"Finance in and of itself is still, to this day, a trust-relationship game." The protocol alone isn't the pitch for institutional capital. The counterparty matters too. @obligatecom Co-Founder Benedikt Schuppli on why the winners in onchain credit understand fiduciary obligations, not just smart contracts.

Idle stablecoins? Meet your new runway rocket with @zothdotio . zOPAL turns them into up to 12% RWA-backed yield zero lock-ups, full liquidity on demand.

We just published @Arc's privacy whitepaper They were offchain for a reason: Payroll, positions, counterparties: none of it was meant to be a public data feed. This is an early look at a proposed design. Learn More and tell us what you think: hubs.li/Q04kXckw0

What if idle stablecoins could extend your runway? Most startups park treasury capital in low-yield positions to preserve liquidity, and leave capital efficiency behind in the process. zOPAL gives treasury teams access to up to 12% RWA-backed yield, with no lock-ups and on-demand liquidity.
