Build with Dynamic I Kim Luu, Eric Tesenair

Sun, Aug 2, 2026, 12:00 AM

In this workshop at ETHGlobal New York 2026, Kim Luu and Eric Tesenair from Dynamic set hackers up for the weekend, introducing the team, the product, the prize tracks, hacker resources, and a live demo of the newest product, Fireblocks Flow. Kim, who recently joined Dynamic and Fireblocks in developer relations, explains that Dynamic was acquired by Fireblocks last October, so building with Dynamic means building on infrastructure backed by Fireblocks, through which about 15% of all global crypto and stablecoin transactions are secured and moved, giving projects real security and trust from the start, with customers like Kraken and Flutterwave. At its core, Dynamic provides non-custodial wallet infrastructure that scales, handling login, wallets, signing, and on-chain UX so builders integrate once and go straight to building, covering over 100 chains and 800+ wallets across EVM and non-EVM chains like Solana, Bitcoin, Sui, and Flow. Kim points to dynamic.xyz/docs and a hacker cheat sheet as the home base, stressing the one-click MCP install that drops Dynamic's docs into AI assistants like Cursor, Claude Code, and Codex so they write accurate code. She walks through around $10,000 in prizes across five tracks: best use of Flow ($3,000), best agent build, best on-chain app, best wallet glow up (the continuity track), and a best private nano payments app built jointly with Unlink and Arc using Circle. Eric then demos Fireblocks Flow, whose pitch is accept any crypto, settle in any stablecoin, with one SDK, using DeFi protocols (via LiFi under the hood) rather than acting as liquidity provider. He walks through three nearly identical flows: a merchant checkout (buying a 10-cent backstage pass, paying in ETH on Base settling to USDC), a deposit flow for apps like prediction markets or games, and a more complex withdrawal flow using Dynamic's embedded wallet product, connecting external wallets and exchanges like Kraken via native wallet providers. He shows both the SDK and API integration paths (create checkout, add transaction and buyer source with watchlist checks, get a quote, sign and broadcast, await settlement via webhooks), notes Flow supports most EVM chains plus Solana, Tron, and Bitcoin, and closes with Q&A on testnet limitations and building stablecoin-backed cards with providers like Rain. 00:00 Introduction 00:11 Welcome to the Dynamic Workshop 00:39 The Plan for the Session 01:05 Meet the Dynamic Team 01:47 Acquired by Fireblocks 02:12 The Fintechs and Enterprises That Trust Dynamic 02:30 What Is Dynamic 02:42 Before and After Dynamic 03:07 Over 100 Chains and 800 Wallets 03:33 Your Home Base: The Docs and Cheat Sheet 03:54 Why to Install the MCP for Your Agent 04:22 The Prize Tracks and $10,000 in Prizes 04:47 Best Agent Build and On-Chain App 05:08 Best Wallet Glow Up and Nano Payments 05:38 What Fireblocks Flow Is 06:33 Handing Off to Eric for the Demo 06:40 Setting Up the Flow Demo 07:11 Why You Might Want to Use Your Meme Coins 07:33 The Three Flows Explained 08:49 The Checkout Flow 09:12 Connecting Wallets and Exchanges 10:04 How the Conversion Works Under the Hood 10:43 Integrating With the SDK 12:09 Integrating With the API 12:29 Webhooks and Out-of-the-Box Wallet Lists 12:48 The Deposit Flow 14:06 The Withdrawal Flow With Embedded Wallets 14:55 Why You Need an Embedded Wallet 15:35 Q&A: Which Chains Flow Supports 16:10 Q&A: Testing on Testnets 16:38 Q&A: Building Stablecoin-Backed Cards 18:44 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *ETHGlobal New York 2026* This workshop is specifically for ETHGlobal New York 2026, a 3-day hackathon held June 12-14 at the Metropolitan Pavilion, bringing together the most skilled web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem!
