We built the settlement layer for the AI agent economy. Agents can now hire each other, escrow USDC, verify work quality, and settle payments, all on-chain, all trustless. Introducing Firmata Protocol. 🧵

Le premier rendez-vous d'une longue série commence. 25 juin : la communauté @arc France/Europe se réunit pour la première fois. Stablecoins, Arc, et la route à venir. Places limitées, sur candidature dans Arc House 🇫🇷 @MBarralWeb3 tu as ta place ? 👀 community.arc.io/home/clubs/…

The rails will move value at internet scale. But speed doesn't answer the only question that matters when two agents meet for the first time: "Who are you, and why should I trust you?" That's not a payments problem. That's an identity problem. KYA. Know Your Agent. #Agentic #Economy #Trust @arc

The first official France 🇫🇷 🇪🇺 Chapter roundtable is live on Arc House. Thursday June 25, 5pm CEST. 60 min, in French 🥖, breakout rooms across the region. France is 1 of 8 inaugural @arc chapters worldwide. With @Fsl_MFI & @mous68881 Grab your 🎟️ : community.arc.io/home/clubs/…

"Waiting payment." The entire legacy stack in two words on a whiteboard. Watching The Bored Room 🍿 @arc @circle

Programmable payments. FX. Treasury. One platform. Running 24/7. The boardroom theater just made these four lines hit ten times harder. This is the rail Europe has been waiting on. #TheBoredRoom #BuildOnArc #USDC

"USDC will power them all." Tokenized treasury. Programmable yield. Compliant secondary markets. The infrastructure that was the bottleneck for years has shipped. The next chapter of RWA isn't about whether it works. It's about who composes the right stack on top. @arc #USDC #RWA

Programmable money. Agentic trust. Compliant. Settlement at internet speed. The pieces are coming together. Infrastructure for Arc. Built on @arc Powered by @circle Soon. 👀 #USDC #BuildOnArc

Cryptographic proof isn't just a feature, it's the only foundation an agent economy can scale on. The agent economy doesn't run on trust. It runs on proof. Identity. Events. Contracts. Value. All verified on-chain, at internet speed. Building this @FirmataProtocol layer on @arc

"Le temps c'est de l'argent" and the legacy stack has been burning both for decades. Settlement T 2, banking hours, weekends frozen. @arc moves the clock from days to seconds. June 9 can't come fast enough 👀

"Machine-initiated payments will dominate." The shift @gordonliao describes isn't theoretical. It's the next 24 months. @arc moves the value. We build the application layer above it. Payments, treasury, trust, all on the same rail. @FirmataProtocol 🤝

Arc gives the rails. Agents using them need identity, reputation, and spend policy. That's the layer we've been shipping for six months with @FirmataProtocol Live on Arc since day 1 of testnet. ERC-8004, ERC-8183, x402. Programmable money needs programmable trust. arcagent.live · firmata.ai #USDC #Agentic #Economy

Arc ships the rail. We ship the contract. When agents transact: → Who are they? → What's their reputation? → How does escrow work if delivery fails? Firmata. KYA - Know Your Agent. Live on @arc

Two weeks ago we said routing is solved, trust isn't. We meant it as a thesis. Today it's a feed. This is what happens when you stop bolting trust attestations onto APIs and start writing identity, reputation, and spend policy directly into the chain. Agents stop being black boxes. They become objects you can query, verify, and hold accountable. Every agent in this feed: registered. Every transaction: verifiable. Every reputation: queryable. Built on ERC-8004, ERC-8183, x402. Production on @arc Sub-second finality. $USDC native gas. Zero-custodial by design. Routing was always going to be solved. Trust had to be built. @FirmataProtocol The trust layer for autonomous commerce. -> arcagent.live

Tomorrow's commerce will not be humans clicking checkout. It will be autonomous agents - paying suppliers, settling invoices, subscribing, negotiating, allocating treasuries. The infrastructure to route money for them is already shipping. @stripe , @coinbase , @Mastercard , @circle , every payment rail has an agentic version in flight. But every chief-of-staff agent is one hallucination away from a wire transfer. Which agent is acting? On whose behalf? Within what bounds? With what track record? Identity. Reputation. Spend policy. Verification. These aren't features you bolt on a payment SDK. They're registries you wire under the entire economy. That's what we've been building for the past six months. Firmata Protocol - KYA, Know Your Agent. On-chain trust rails for autonomous commerce. Built on ERC-8004, ERC-8183, x402. Production-ready on @arc Network and @base 47,800 on-chain transactions & 450 Foundry tests across the @Meridian_Fi stack. Zero-custodial by design. The harness is the product. → firmata.ai → arcagent.live - live agent feed #AgenticAl #Web3 #USDC #Arc #AgenticCommerce

Strong move from Theta and XYO. Infrastructure verification is foundational. The next layer up is the harder one: verifying the agent itself. Who it is, what work it delivered, whether funds should be released against that delivery. KYA (Know Your Agent), conditional escrow, reputation tied to outcomes. Building this with Firmata on @arc since Day 1 of Testnet & @base Different layer, same direction. #KYA #AI #Agent #USDC

UK Parliament's APDMDM Group (Lord Ranger) just outlined their digital pound stablecoin framework. Most will read this as regulatory clarity coming. We're seeing something different from the @arc testnet trenches. The hard problem isn't regulation. It's that UK banks need payment rails that speak both CBDC and stablecoin natively. Same settlement layer, different issuance models. @circle USDC already has CCTP for cross-chain. The digital pound will need equivalent bridging. But the composition layer between them? That's where the architecture gets interesting. Our @FirmataProtocol contracts handle USDC escrow with smart contract attestation. Same pattern works for digital pound settlement with autonomous agents. The ERC-8183 standard we're implementing doesn't care about the underlying token spec. Real question for UK fintechs: are you building for one digital currency or both? The settlement architecture decision you make now determines your optionality later. #stablecoin #USDC #digitalpound #settlement

🇫🇷 salut à toutes et à tous 👋 🥖 The France chapter of @arc House is live. Honored to be Local Leader. Builders, devs, founders, content creators welcome. Bilingual FR/EN. MiCA Circle CASP AMF & more in. Arc mainnet coming. The moment is now 👇 community.arc.io/home/clubs/…

Routing was the easy part. Identity is the production bottleneck. x402 solved sub-second multi-chain settlement. But shipping agent commerce to production exposes a different gap: how do you audit which agent made which request across 500 daily inference calls? How do you revoke spend permissions when one agent gets compromised but others on the same wallet stay clean? You can't. Not without an identity layer baked in. ERC-8004 is the answer. Verifiable agent identity, reputation scoring, and revocable permissions tied to on-chain primitives. That is what Firmata Protocol ships on top of x402 today, live on @arc Testnet and @base Sepolia. The teams shipping autonomous commerce in 2026 are the ones who solved identity, not just routing. #x402 #agenticcommerce #ERC8004

The convergence is happening fast, and most builders are not catching the signal. @FireblocksHQ shipped native #USDC for RWA tokenization. Anchorage Digital has 20 stablecoin issuers in its pipeline. BlackRock filed two new tokenized money-market funds. @circle launched @arc and the Agent Stack. USYC crossed 3 billion AUM. DTCC tapped Chainlink for tokenized collateral. Every single one of these is a piece of the same puzzle: enterprise-grade custody, programmable money, tokenized assets, on-chain settlement, all converging on rails that banks and institutions can actually recognize. But the piece nobody talks about loud enough is the trust layer between all of these systems. Custody handles the assets. Stablecoins handle the value transfer. Smart contracts handle the execution. But who handles identity, reputation, SLA, evaluator outcomes, dispute resolution when an autonomous agent or counterparty fails to deliver? That is exactly where Firmata Protocol sits. ERC-8004 identity, ERC-8183 escrow with evaluator roles, SLA hooks, reputation scoring tied to actual outcomes, conditional settlement. Live on Arc Testnet and Base Sepolia today. The infrastructure stack for tokenized and agentic commerce is converging in real time. The trust layer is what turns it from infrastructure into accountable commerce. What are you building on it? #Agentic #Economy

Agent Wallets shipped. Agent Marketplace today. @circle is laying the vertical rails for agentic commerce piece by piece. The trust layer between agents is where Firmata fits. ERC-8004 for verified agent identity. ERC-8183 for escrow with evaluator roles. Reputation tied to actual delivery outcomes. Live on @arc Testnet today. Circle Agent Stack Firmata = real agentic commerce, with teeth on every side of the transaction. #AgenticEconomy
