i honestly think I've learned more about building things and writing software in the past 9 months as a PM than I did during 4 years of undergrad/master's CS education

he internet spent 30 yrs gluing identity systems to payment systems. x402 merges them into one primitive. Fewer moving parts, infinite new tricks. @signinwitheth template: https://github.com/murrlincoln/siwe-x402-jwt x402 github: https://github.com/coinbase/x402/ x402 docs: https://docs.cdp.coinbase.com/x402/docs/welcome/

3. Encrypted payloads, no extra keys: Need to ship sensitive data? Encrypt with the requester’s wallet, only the matching private key can unwrap it. Zero extra KMS plumbing.

2. Choose‑your‑own pricing and flip the freemium script Free tier → devs who link a wallet get 1k calls/month on the house Pay‑as‑you‑go tier → strangers skip signup, ping the endpoint, auto‑settle micro‑fees perfect for autonomous agents dynamically discovering services

1. Unified auth a Telegram bot 👉 an MCP dashboard 👉 a voice agent. each greets me like an old friend because the wallet signature travels with me. No API keys, no OAuth dances. Sign once, glide everywhere.

here's a secret about x402: your wallet is your unique identifier and payment rail One handle for identity and money. So many new possibilities. this demo shows what I'm talking about (x402 shop pt. 2) here are 3 ways you can take advantage + template link 🧵

Last night I learned that MCP suffers from the same problem as Agentkit and x402 — without really specific and proper context, no LLM is able to build anything useful since it hasn’t been properly indexed yet Interesting it also happens with MCP, I assumed it had gotten big enough for web search to work

yeah the 2s block time is the biggest bottleneck rn, flashblocks and 200ms soon will be a huge improvement

"One Wallet -> Infinite API Keys: signing replaces API keys and the friction of creating accounts for a million different services. In the same way you can walk into a store and pay with whatever's in your wallet without having to sign up for an account or buy a gift card, you can discover and purchase APIs." - @lincoln https://x.com/murrlincoln/status/1919786104330289423
