AI agents are moving money autonomously.
Most of them sign with a private key in a .env file. copyable, stealable, and invisible at runtime.
I built AgentGate to fix that
AgentGate is an AI agent that sends ETH transactions but it cannot sign anything without hardware approval.
Built with:
โ @Ledger hw-app-eth SDK
โ Speculos device emulator
โ Claude AI for natural language
โ Ethereum Sepolia testnet
@Ledger The key insight:
If an attacker compromises your agent and tries to drain funds to a different address you see it on the device screen before it happens.
The agent proposes. The hardware decides.
Prompt injections end at the screen.
@Ledger The flow:
You type: "Send 0.001 ETH to 0x..."

Claude parses intent
โ
ethers.js builds the EIP-1559 tx
โ
Transaction appears on the Ledger device screen
โ
You approve. Hardware signs. Broadcast.
I recently turned 33, and every year I want to go back to 21-year-old Patrick with a list of lessons.
If you're in your 20s, these are for you.
Most lessons only land after an ass-whooping. And even then, you usually miss them the first time.
The era of "Writing Code" is slowly being replaced by the era of "Directing Intent." ๐ค๐๏ธ
โIn 2026, if youโre still hand-coding every basic CRUD operation, youโre working too hard. The top devs right now are the ones who can architect systems and let AI Agents handle the implementation, refactoring, and PRs.
โWe aren't coders anymore; we are AI Orchestrators. The syntax matters less; the logic and architecture matter more.
โAre you fighting the agents, or are you leading the team? ๐ ๏ธโจ
