TL;DR: GAIMIN scaled onboarding by making crypto invisible at first touch: seedless sign-in, gasless first actions, no chain picker, one app surface—which helped them activate 415k+ gamers. This post tears down that flow and shows how to ship the same UX with Openfort (embedded wallets, passkeys, 4337/7702, Paymasters), plus what to measure so finance sees payback—not just gas bills.
The problem GAIMIN solved (and you probably have too)
Players arrive to play, not to install extensions, write seed phrases, or pre-fund gas. Every extra step kills momentum. GAIMIN’s launcher solved this by keeping the first action Web2-simple and surfacing crypto only when it adds value. Result: over 415k users onboarded.
The pattern
- Seedless creation at sign-in (passkeys/social).
- Gasless first actions (sponsored via Paymaster).
- No chain picker up front (defaults first).
- One surface: wallet + marketplace + inventory inside your launcher.
Ship it with Openfort (practical map)
1) Seedless sign-in → wallet silently ready
Use passkeys/social login to create an embedded, non-custodial wallet at auth time.
- Openfort for Gaming overview (Unity/Unreal support, gas sponsorship):
- Passkeys primer, why passkeys reduce bounce.
2) Make the first mile gasless
Start users with sponsored transactions so they feel progress before they learn gas.
- Recipes (ready-to-copy): EIP-7702 + Paymaster, swaps, Solana, x402, etc.
- Gaming page explains Paymasters & batching benefits for retention.
3) Don’t ask for networks (yet)
Default to one network; surface choices only when relevant (e.g., bridge or marketplace context).
- 7702 lets an EOA temporarily “borrow” smart logic without moving assets—great for keeping an EOA address while adding smart features.
4) Keep everything in your launcher
Minimize tab hops. Keep marketplace, inventory, wallet inside your shell for consistent context and fewer drop-offs.
- Openfort Gaming shows in-app flow patterns + engine support.
Architecture choices (without the jargon)
- ERC-4337 smart accounts: full programmability, strong policy controls, and paymaster-sponsored gas. Good when you need rich rules and session keys from day one. (Openfort supports 4337, entry points, bundlers.)
- EIP-7702 “smart EOAs”: keep your EOA address and temporarily attach smart behavior for specific actions (batching, sponsorship, scoped keys) with lower overhead. Ideal for mass onboarding and compatibility. (Openfort 7702 guides + delegator account.)
Pragmatic rule: start with 7702 to minimize deploy costs; switch to 4337 where you need richer, persistent policies.
What changed in the funnel (and why it converts)
Before: sign-up → install wallet → seed phrase → buy gas → (maybe) return.
After: sign-in → wallet exists → click → success → explain crypto after the win.
That re-ordering is the whole game. GAIMIN’s numbers prove it at scale.
Guardrails & metrics to defend the spend
Track three numbers by cohort (OS, device, geo):
- Time-to-first on-chain action (target: seconds).
- Gasless success rate (by method/API route).
- D1/D7 retention after first success (sponsored vs. unsponsored).
Tie sponsorship cost to these cohorts so finance sees CAC payback, not just a gas line item.
Implementation checklist (Openfort links)
- Auth → Wallet: wire passkeys/social to embedded wallet creation.
- Sponsorship: enable a Paymaster; start with allow-listed methods + daily caps; expand with ROI. (See Recipes.)
- 7702 or 4337: pick per-flow; mix if needed (7702 for day-0, 4337 for advanced).
- Launcher UX: keep marketplace/inventory/wallet in one surface (Unity/Unreal supported).
