Meet the Recipients
1Shot API
What they’re building: 1Shot API is the onchain automation layer, letting agents pay for API access directly onchain.
CDP products used: Onramp (wallet or API), x402, AgentKit
Links: Website/App · Docs/Repo
Hedwig
What they’re building: Your freelance assistant that helps manage budgets and onchain tasks.
CDP products used: CDP Wallet SDK, Onramp (wallet or API)
Wish
What they’re building: Wish turns intent into action. Shoppers save products from anywhere, and Wish converts those signals into real demand data brands can act on—think pre‑orders, drops, and back‑in‑stock pledges. The wishlist lives with the user (not a single store), so it follows them across devices and merchants. Under the hood, Wish enables micropayments and pay‑per‑action flows so fans can support launches, reserve items, or tip creators without clunky checkouts.
CDP products used: CDP Wallet SDK (embedded wallets for frictionless accounts and secure signing), Onramp (card/bank funding into stablecoins), x402 (pay‑per‑action micropayments for pledges, tips, and preorders).
Cross Post
What they’re building: Seamlessly bridge X and Farcaster with automatic cross-posting that syncs tweets to casts.
CDP products used: CDP Wallet SDK, Onramp (wallet or API)
PrediBot
What they’re building: Your AI-powered prediction market assistant with onchain settlement.
CDP products used: CDP Wallet SDK (declared)
Hydrex
What they’re building: Hydrex is a liquidity‑neutral ve(3,3) toolkit that helps protocols and LPs coordinate incentives without constant manual tuning. It curates token lists, optimizes routing across pairs, and provides guardrails for emissions so projects can bootstrap depth while protecting users from poor routes. The result is steadier liquidity and saner incentives for partners building on Base.
CDP products used: Onramp (to fund LPs and strategy addresses), Base Paymaster (gas sponsorship for smoother user flows), Data API (price/liquidity data to inform routing and list curation).
Yield Seeker
What they’re building: Yield Seeker deploys AI agents that scan DeFi markets, simulate risk, and execute yield strategies on your behalf. Agents create their own wallets, fund themselves, and periodically rebalance positions—prioritizing predictable returns and capital safety over degen swings. Ideal for power users and programmatic treasuries that need hands‑off compounding with clear audit trails and role separation.
CDP products used: CDP Wallet SDK (per‑agent smart wallets and secure signing), Onramp (seamless fiat→stablecoin funding), Swap API (rebalance/route across assets as strategies change).
PayStabl
What they’re building: Stablecoin payment platform for AI agents.
CDP products used: CDP Wallet SDK, Onramp (wallet or API), x402
MCPay
What they’re building: Usage‑based payments for MCP server tools using x402 (pay‑per‑API‑call).
CDP products used: CDP Wallet SDK, Onramp (wallet or API), x402, AgentKit
ROZO
What they’re building: Your map to spend crypto with bigger rewards.
CDP products used: CDP Wallet SDK (spend permission)
Farm Frens
What they’re building: A playful Telegram mini‑app where players collect, trade, and upgrade characters—think Animal Crossing vibes with quick mobile loops. The team focuses on low‑friction onboarding: new players can jump in, then top up when they’re ready to unlock premium items or events. Rewards and purchases are handled onchain behind the scenes so the game stays fast, friendly, and shareable.
CDP products used: CDP Onramp
Pretium Finance
What they’re building: A payment platform enabling users to pay for in‑app experiences and services.
CDP products used: Payouts on Base network (declared)
