Overview
Real-world Zafeguard SDK recipes — production patterns for smart accounts, DeFi integrations, and gasless transactions.
Overview
End-to-end SDK examples for real-world use cases. Each example shows the full flow — from key derivation to on-chain confirmation — using the Zafeguard component library.
Wallet Solutions
End-to-end blueprints for production wallet shapes. Pick the section that matches your product tier; each is composed from @zafeguard/mpc-sdk plus the workflow canvas.
| Solution | Description |
|---|---|
| Embedded Wallet Solution | Consumer-facing wallet — device share + cloud cohort, RecoveryKind clauses, presignature pool. Includes the Smart Account Flow production pattern (LINE LIFF / Telegram / Discord / in-game / email-login): one MPC root key, per-user BIP-44 derivation, counterfactual Gnosis Safe, gas-sponsor workflow. |
| Custody Whitelabel Solution | Institutional custody whitelabel — hot (ClusterAgent cluster), warm (server-side EmbeddedAgent online), cold (the cold-wallet flow partial-ferry). Three tiers, each with its own topology and policy posture. |
Smart Accounts
| Example | Description |
|---|---|
| Gnosis Safe — Lazy Deploy + Gas Sponsorship | Create a smart account per user that auto-deploys on first use. A relayer MPC key sponsors all gas. |
DeFi & Token Operations
| Example | Description |
|---|---|
| Gasless Transfer with Permit2 | Transfer ERC-20 tokens without a prior approve() using a Permit2 signature signed by an MPC key. |
