We built the first autonomous machine-to-machine energy nanopayment. A solar panel sells electricity to a Bitcoin miner. No human involved — just two $2 chips negotiating price, streaming payments over Bluetooth on-chain. 24 payments in 4 minutes. Each from $0.00001 to $0.0001.

How it works: ☀️ eCandle broadcasts a dynamic electricity price over BLE ⛏️ Bitaxe evaluates profitability — buys when cheap, stops when expensive 💸 Each 10-second "slice" triggers an EIP-3009 signed payment 🔗 Proofs settle via @circle on Arc Testnet. Zero gas.

The "fan moment" tells the whole story: Price drops → fan spins → energy is being bought Price spikes → fan stops → pure economic logic No wallet app. No browser. No human. Just machines trading value.

This required three layers working together: 🔋 @arkreen_network eCandle — real deployable solar hardware, not a simulator 🔐 @tlay_io BoAT SDK — on-chip EIP-3009 signing on a microcontroller 💰 @circle Nanopayments — sub-cent payments + zero-gas settlement on Arc

The pattern extends far beyond energy: • EV charging — pay per kilowatt-second • Edge compute — buy GPU time per millisecond • Bandwidth — pay per megabyte • Sensor data — pay per reading Device-as-a-Wallet is the payment layer for the machine economy.

Acting autonomous! This is a game changer

Exciting to see @circle @arc pushing boundaries! Machine payments are born for this moment. x402 agentic service + Nanopayments. 🤖⚡ The future of agent economy is here.

Distributed physical infra + AI + on-chain settlement. This is the hardest and most real direction in crypto right now. Respect. ⚡

So cool - this is the stuff I got into this space to see Is the pricing negotiation dynamic? Does the miner adjust its bid based on real-time solar output or is it fixed rate?

A $2 chip just paid for its own electricity. Automatically. While you slept. This M2M demo: $0.000042 per 10-second energy slice via BLE — zero human involvement. What strikes me most: 1️⃣ The eCandle isn't just generating power — it's running a dynamic pricing engine 2️⃣ The Bitaxe isn't just mining — it's making autonomous purchasing decisions based on real-time profitability 3️⃣ The device isn't just a producer — it's also a consumer. DePIN + autonomous settlement in one chip. The pattern is universal — any device with a wallet, a local communication channel, and a settlement layer can participate. The future isn't just AI agents with wallets. It's also every device with a chip.

Wow that’s amazing !

Enabling 'Device as Wallet' via BoAT MWR SDK is how we bring the Agentic Economy to the physical edge. Huge potential here. 📟

This is crazy So you telling me we won’t have to worry about keeping up with bills anymore… wow

This is the vibe we live for 🔥 Yes—imagine your solar panel paying its own way!

How'd you build this?

An efficient system, that is the standard the new financial system requires🤯👏

programmable machine economy

But it’s paying whom?
