Why are major banks racing into crypto? Our CEO @nikil went on @CNBC to break down the regulatory shift that changed everything with @TaliaKaplan and what it means for institutions.

Doing our piece to scale Solana for all builders - latency, throughput and scale at the RPC layer! Thank you @afscott for the opportunity to chat!
Alchemy@Alchemy

If you're building on Solana today, this convo is for you. 💥 Our CTO @gponcin joined @afscott to break down: - Why Solana outgrew its infra - What it really takes to build reliable, multi-region RPC - Hidden pain points with latency, archive data & missing blocks - How infra becomes invisible when it “just works” 🎧 Listen here: podcasts.apple.com/us/podcast/gui…

Stablecoins have been crypto's workhorse for years. Now, post-GENIUS Act, banks, fintechs, and payment platforms are racing to ship stablecoin and tokenized deposit rails. Our co-founder @thejoelau spoke to @coindesk about what this means for financial services 🧵
