Startup GTM work is often expensive and manual. Founders and sales teams need audience research, public profiles, contact enrichment, email verification, outreach copy, and delivery, but these steps usually require many tools, subscriptions, credits, API keys, and spreadsheets. In this tutorial, Blessing Adesiji from the Circle DevRel team shows how to build a GTM lead research agent with Circle Agent Wallet and Circle Agent Marketplace. The agent gets a product description, a target LinkedIn URL, a small USDC budget, and a clear task. It can pay for useful services, enrich contact data where available, send the final brief by email, and return a spend log. This episode covers: - Why GTM research is a strong use case for agent payments - How to give an agent a product, target profile, budget, and goal - How Circle Agent Wallet and Marketplace services support paid workflows - How to structure a prompt for lead enrichment and outreach - How to review services used, total spend, and payment receipts Explore more content for building on Circle and Arc: https://developers.circle.com/ https://docs.arc.network/

CCTP upfront fees let you send an exact USDC amount when a transfer uses Fast Transfer or the Forwarding Service. The fees are quoted and collected upfront on the source blockchain instead of being deducted from the transferred USDC. In this Release Notes episode, HJ from Circle DevRel explains the new quote and contract flow, why it matters for exact destination amounts, and the integration detail that can make a quote-bound transaction revert.
