Sendero is a vertical AI agent that replaces the entire travel operations software stack with a single agent runtime powered by Google Gemini. The travel industry runs on six disconnected vendors: GDS, TMC, CRM, expense tools, payment rails, and human agents. A single expense report still takes hours. Sendero collapses this into one AI agent that handles the full trip lifecycle in under ninety seconds. How Gemini powers Sendero: Gemini 2.5 Flash drives sub-second OCR for passports, receipts, invoices, and boarding passes with Zod-pinned structured extraction. Gemini Flash Image generates collectible trip stamp artwork in parallel with agent workflows. Gemini Pro handles complex multi-step reasoning for policy evaluation and itinerary optimization. Enterprise-grade architecture: Multi-tenant by design with isolated workspaces, scoped API keys, and HMAC-signed requests. Durable Vercel Workflows checkpoint every booking step, surviving deploys and resuming days later. Column-level encryption protects traveler PII. Langfuse and Arize Phoenix provide LLM-as-Judge evaluation and full agent observability. Four channels, one runtime: Travelers interact via WhatsApp. Operators manage via Slack. Finance reviews on the web dashboard with Liveblocks collaboration. Other AI agents call Sendero through MCP, OpenAPI, and llms.txt, paying per-call via x402 nanopayments. 128 production tools spanning flights, hotels, ground transport, visa eligibility, eSIM provisioning, FX quotes, document scanning, and settlement. Real supplier integrations via Duffel across 500+ airlines. Won Best Google Gemini Implementation at the Arc Hackathon. Google invited us to TechEx on that win. Built on Y Combinator’s thesis that vertical AI agents replace SaaS. Harvey did it for legal. Sierra for customer service. Travel ops is the open seat.

Sendero turns messy travel requests into quotes, bookings, refunds, invoices, and on-chain settlement trails. Agent layer on Vercel Workflows + Fluid Compute (durable, encrypted, resumable). Money layer on Arc. Two revenue legs from day one. Clerk Billing gates SaaS tiers; x402 nanopayments meter every search, policy check, and tool call in micro-USDC, batched and settled on Arc L2 in one userOp that atomically fans funds to vendor + agency commission + Sendero fee + reputation tip. Card rails can't do atomic multi-leg settlement — Arc unlocks it. On-chain core: SenderoGuestEscrow (0x640e15B2B7cBa421c93dA1514f8E6Ba3e11f8515, Arc Testnet, chain 5042002, verified). Peanut-style payment links plus a travel state machine — reserve → commit → confirm → settle — with recipient-bound ECDSA signatures, optional OTP claimCodeHash, upper-bound reservations for fare drift, buyer reclaim on timeout. Sits beside ERC-8183 escrow and ERC-8004 agent identity/reputation. Self-hosted Ponder indexer keeps events in Postgres + GraphQL. Wallets: Circle Modular Wallets (passkey MSCAs for travelers and guests) + Circle Developer-Controlled Wallets (treasury), both on Arc. Circle App Kit powers swap (USDC↔EURC), CCTP bridge, send, and unified balances across testnets. Settlement uses Circle Nanopayments + Gateway to batch thousands of off-chain signatures into one on-chain tx, eliminating per-payment gas. Souvenir NFTs ship via Circle's SCP ERC-1155 template + Gas Station; Webhooks + Event Monitors feed the indexer. Beyond flights and hotels: visa-aware quotes via Sherpa with MRZ-validated PassportVault (pgcrypto AES-256, per-tenant DEK), Gemini OCR with Zod-pinned outputs, Google Maps travel-safety briefs, and an MCP + llms.txt + OpenAPI surface so other agents can book through Sendero by spec.

WhatsApp Agentic Financial Workspaces — a next-generation framework for conversational finance that allows individuals and teams to manage their entire financial life directly inside a WhatsApp chat. By combining AI automation, Circle’s USDC/EURC stablecoin infrastructure, and Kapso’s WhatsApp Cloud API, we transforms WhatsApp into a secure, AI-powered Financial Operating System (OS) on Arc's Gateway. This Proof of Concept showcases how users can seamlessly send and receive payments, manage payroll, handle invoicing, pay utilities, open and track multi-chain wallets, and monitor business metrics — all through natural chat interactions. Under the hood, it integrates Anthropic Claude for intelligent financial conversation orchestration, Circle SDK for programmable stablecoin operations, and a serverless Cloudflare Workers deployment for global, low-latency access. Using payment gateway users can sweep funds across all the wallets on testnet or mainnet for a unified USDC balance and being able to transfer cross-chain via the gateway contract to any recipient. We also support as can be seen in our packages/transfer-core split payments between different whatsapp numbers, ERC-681 payment link, gas, transfer, bridge, swap and other services and protocols built using USDCKit. Our Whatsapp UI package is the base for beautiful future guiding principles for multi-party interactions were everything must be Native WhatsApp UI. We have a separate modular architecture (Motora Open Finance Engine + Shiva SDK) that empowers developers to build and extend agentic financial workflows, proving the potential for stablecoin-first, AI-driven financial operations accessible to anyone with WhatsApp — the world’s most widely used communication platform with +3b ACTIVE USERS making it the best distribution channel for stablecoins in regions such as Latam and beyond.

In this hybrid hackathon powered by Arc and Circle, developers will build the next generation of Agentic economic applications using Circle’s Nanopayments infrastructure with settlement on Arc in USDC. For the first time, high-frequency, usage-based transactions between users, APIs, and AI agents can operate without gas overhead eroding margin. Arc provides stablecoin-native settlement with predictable, dollar-denominated USDC fees and deterministic, sub-second finality — enabling real-time coordination and economically viable per-action pricing at scale. 📅 April 20 – 26, 2026 • Apr 20 – 25 (Online): Submit projects by Apr 25. • Apr 25 (On-site Build – SF, CA): Teams refine projects. • Apr 26 (On-site Demos & Awards – SF, CA): Live pitches & winners announced.
