Blockchain Developer Business Cards

Oval 2.5×3.5 on 38pt Trifecta Red feels deliberate sliding across hackathon tables and investor pitch folders when every engineer hands a white rectangle. The crimson core seam reads bold before VCs see your protocol line. Thirty-eight-point stiffness survives laptop bags and coworking folios through conference season. The oval silhouette photographs cleanly beside architecture diagrams founders already screenshot for Telegram groups.

For a smart-contract lead testing one ETHGlobal circuit, three VC partner desks, and a targeted DAO outreach push, 100 cards validates layout before scaling to 250 or 500 across a growing client roster. Starter pricing keeps indie builder budgets lean while still delivering a tactile follow that outlasts buried Discord DMs after a booth chat. Scale quantity once portfolio URLs and direct lines prove stable.

One labeled QR to GitHub highlights, audit intake, or a flagship dApp demo outperforms cluttered social icon rows on a red-core oval face. We test scans under expo hall LEDs and hotel Wi-Fi during proofing. Keep email and mobile lines larger than the QR because fund managers often reach out from back rooms when they want to lock a security review slot before launch week. Many shops start near 100 pieces at 2.5x3.5.

Lock studio palette, oval die, and Trifecta Red stock, then swap developer name, chain cue such as EVM or Solana, and direct mobile from a spreadsheet. A 100-count starter per engineer validates layout before you scale. Shared visual identity with personal callability converts accelerator referrals faster than one generic OTA screenshot after a demo day.

Lead with legal name, one specialty line such as smart contracts or indexing, and the best direct contact path. Skip long whitepaper paragraphs that belong on the website. Free Design Setup balances hierarchy so GitHub handles stay readable on the oval 2.5×3.5 red-core face without crowding the number partners dial during due diligence.

Yes. The triple-layer core resists curl when cards ride beside charging bricks through multi-day hackathons. Gloss faces keep accent colors vivid under bright sponsor hall lighting. Human inspectors check stiffness on every 100-count oval run before boxes ship to your coworking desk.

Production typically runs a few business days after digital proof approval. Ground transit from the nearest CA, OH, TX, FL, or NJ plant usually delivers in about 3-5 business days depending on carrier routes. Rush tiers appear at checkout when a mainnet launch or token event is tighter than standard ground allows. Checkout separates production from shipping so sprint calendars stay honest.

The printed QR points to the URL established at production time. If your portfolio vendor changes later, use a stable landing page that redirects to the new tool so existing cards keep working. We recommend that pattern during Free Design Setup so contacts scanning cards from last year's conference lanyard still reach live repos without forcing a mid-sprint reprint. Many shops start near 100 pieces at 2.5x3.5.

Regional hubs in Rhode Island, Texas, Ohio, Florida, California, and Kentucky shorten ground miles for most tech-event markets. Northeast builders from RI, Texas for Gulf fintech corridors, Ohio for Midwest enterprise pilots, Florida for Southeast crypto summits, California for West Coast protocol launches, and Kentucky for mid-South incubator partners. Checkout shows honest calendars before you commit to a demo week. Many shops start near 100 pieces at 2.5x3.5.
