JAW SDK Best Practices

Guide for building applications with the JAW SDK passkey-authenticated smart accounts on EVM chains with programmable permissions.

When to use

Reference these guidelines when:

  • Installing or setting up @jaw.id/wagmi, @jaw.id/core, or @jaw.id/ui
  • Configuring the JAW connector or provider (API key, modes, paymasters, ENS)
  • Connecting/disconnecting wallets with passkey authentication
  • Sending transactions (single or batched) through JAW smart accounts
  • Signing messages or typed data (EIP-191, EIP-712, ERC-7871)
  • Granting, querying, or revoking permissions (ERC-7715)
  • Implementing subscription payments or recurring charges
  • Setting up gas sponsoring with paymasters (ERC-7677)
  • Issuing ENS subnames to users during onboarding
  • Implementing Sign-In With Ethereum (SIWE)
  • Building headless integrations, server-side operations, or AI agent wallets
  • Using the Account class directly (no UI)
  • Upgrading EOAs to smart accounts via EIP-7702 (preserving the existing address)
  • Integrating with embedded wallet providers (Privy, Turnkey, etc) for EIP-7702
  • Building stablecoin payment flows (USDC gas, batch payouts)
  • Choosing between CrossPlatform and AppSpecific authentication modes
  • Implementing a custom UI handler for app-specific mode
  • Building React Native / Expo apps with passkey-authenticated smart accounts
  • Reviewing or debugging code that uses JAW SDK

Key facts

  • Packages: @jaw.id/wagmi (React), @jaw.id/core (vanilla JS / server), @jaw.id/ui (app-specific mode UI)
  • API Key: Required. Get one at https://dashboard.jaw.id
  • EIP-1193 compatible: Drop-in replacement for MetaMask or any wallet
  • Smart accounts: ERC-4337 with passkey signers, gasless tx, batch ops, permissions
  • EIP-7702: EOAs can upgrade to smart accounts while keeping their address via Account.fromLocalAccount(config, localAccount, { eip7702: true })
  • EntryPoint: v0.8 only (for paymasters)
