🤖 How to build your first AI agent from scratch in 2026 — a complete thread for developers No hype. No fluff. Just the real steps. 🧵 1/8 #AIAgents #DevTutorial #BuildInPublic

Following the Espresso docs walkthrough in real time is one of the clearest ways to understand how the network actually delivers fast confirmations across chains. Spinning up a testnet client lets you see the system from the ground up. You initialize the node, connect to peers, watch the sequencing logic activate, and observe how blocks get propagated through the network. Once you send your first block through the testnet flow, the picture becomes even clearer. You can literally watch the lifecycle of a transaction as it moves from local submission to network broadcast to confirmation by Espresso. The confirmation flow is where builders start to understand the real power of Espresso. Instead of waiting for slow L1 finality or relying on trusted centralized relayers, the network gives you a cryptographically verifiable confirmation that other chains can rely on within seconds. This is what enables trust minimized composability. It is the missing piece that makes cross chain design more predictable and far more secure. If your team wants to follow the same steps, I will share the full walkthrough so you can boot a client, send your own block, and observe confirmations exactly as the network sees them. Hands on testing reveals more than any explanation ever could. It shows why fast confirmations matter, why the ordering layer is so important, and why Espresso is becoming essential infrastructure for anyone building across multiple chains. This is how cross chain development becomes easier, faster, and safer. Real confirmations. Real interoperability. Real onchain composability. @espressosys @espressofndn #DevTutorial #Testnet #Web3Dev #Espresso #EspressoNetwork
