Alright frens, its official.
I will be speaking at @EFDevcon

On x402 agentic markets:
- what's wrong with open agentic commerce
- why x402 merchants are gonna die
- how we can fix this

see you all in Mumbai,
Thanks @EFDevcon

If you are a programmer, stop obessing over what is optimal to study/upskill in.

Engineers with staying power have depth in a lot of areas.

The goal is to have a deep and wide understanding of software engineering, not to pick a "shortcut subject"

Pick a subject and stick with it for 90 days.

Be a learning machine, not a short term knowledge day trader.

Low level programming, distributed systems, ML, networking, math, file system design, cryptography, computer vision, formal verification, technical writing, etc etc

all of those are good choices. Keep moving. Learning is never wasted.

Endlessly scrolling to figure out where the winds will blow tomorrow is a waste of time.

Success comes from preparation, not anticipation.

the "tech bro" dilemma in 2026

what should I learn bro?

"Learn a programming language"
– which one bro

"Depends. What's your goal?"
– I wanna be AI-proof bro

"Then start with Python"
– Python is too easy bro. AI writes it better than me

"Then learn Rust"
– Rust is too hard bro. AI writes it anyway, what's the point

"If AI writes everything, learn how AI works"
– that needs math bro

"Learn math"
– shut d fck up bro

"Fine, skip the math. Just build AI agents"
– the framework I learned got deprecated last Tuesday bro

"Then learn the fundamentals. Those don't get deprecated"
– that takes 4 years bro

"That's literally what a CS degree is for"
– I have one bro. I learned Java applets

"Then do a master's"
– 2 more years and a loan bro

"Skip college. Take online courses"
– recorded three model releases ago, bro

"Learn by building projects then"
– what do I build bro, everything already exists

"Clone something that exists"
– I asked Claude to clone it. Done in 10 minutes. Learned nothing bro

"Contribute to open source"
– every good first issue gets claimed in 4 minutes bro

"Just grind LeetCode and get a job"
– Claude solves hards in 4 seconds bro

"Then why do interviews still ask LeetCode"
– because the interviewer grinded it in 2019 and wants revenge bro

"Aim higher. Learn system design"
– bro my app has 12 users

"Get more users. Learn marketing"
– I'm an engineer bro, I don't do marketing

"Build in public then"
– I have 43 followers and 38 of them are bots bro

"Join a startup, learn on the job"
– they want 3 years of experience for an intern role bro

"Then start your own startup"
– I don't have an idea bro

"Build an AI wrapper"
– OpenAI will ship it as a feature next week bro

"Build in crypto"
– crypto is dead bro

"Crypto isn't dead"
– my portfolio is bro

"So what are you learning right now?"
– watching a 3-hour video on what to learn bro

[Zaryab @zaryab_eth]

Learning never goes in vain

software builders today r painfully anxious - wasting hours/weeks on “what to learn if AI can do it all”

“Learning” - the act in itself is a super valuable skill.

if for nothing else, learn how to learn efficiently, from first principles

use create-8004-TAP-agent to create new TAP agents or register/bind existing ones.

shoutout to @VittoStack for create-8004-agents scaffold CLI tool.

https://t.co/2a3dKgmUgD

[Zaryab @zaryab_eth]

ERC-8004 gave us Trustless Agents.
I built Trustless Agents Plus - TAP

A solution for fragmented multi-chain ERC8004 AI Agents.

With TAP, your multi-chain Agent acts like ONE.

One aggregated reputation.
One canonical identity.
On-chain verifiable.
Soulbound.

[Zaryab @zaryab_eth]

built a dedicated claude-code plugin for solidity gas optimizations.

- skills: deep domain knowlegde solidity evm opcodes & gas mechanics
- watch mode: to catch gas leakages in real time.
- analyzes, optimizes and also compares gas improvement for your contract.

[Solidity @solidity_lang]

Solidity v0.8.34 out now.

This release fixes a high-severity bug in the IR pipeline affecting versions 0.8.28 through 0.8.33 (`--via-ir`, not enabled by default).

If your code does not use both `--via-ir` and delete on a transient state variable, your contract is not affected.
