Watching incoming USDC & USDT: NestJS + viem and the potholes of free RPCs

I had a deceptively simple task: watch a set of addresses and push a Telegram notification the moment a stablecoin lands on one of them. The classic "a freelancer got paid and found out instantly, instead of when they next opened an explorer." I started with USDC on Base, then added USDT (TRC-20) on Tron — and the second chain slotted into the same architecture almost for free, viem included. I'll get to that too. Stack: NestJS + viem + BullMQ. You'd think: subscribe to the ERC-20 Transfer event

GitHub Actions SEO: gate PRs on broken links and schema

Originally published on the Lyra blog. Code review is good at catching logic bugs.

I recently looked at the stats for every game played and stumbled on a number that surprised me: real players win only 25% of matches. When I wrote the bot logic, I never expected this outcome. They were meant to fill empty lobby slots and give people a chance to practice before playing against humans, not to become the final b

Next.js App Router Caching: What Actually Gets Cached (and What Doesn't)

You deployed a Next.js App Router app, called revalidatePath() after a mutation, and the page still shows stale data. Or you disabled caching on a fetch call and the page is somehow still cached. Or you migrated from Next.js 14 to 15 and everything that was working broke silently. All of these happen because the App Router has four separate caching layers, and they each have their own invalidation story. Developers hit these bugs constantly because the mental model of "there is one cache" is wro
