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.
