Build crypto wallets using Circle Modular Wallets SDK with passkey authentication, gasless transactions, and extensible module architecture. Use when: creating crypto wallets with passkey-based (WebAuthn) registration and login, sending gasless transactions using Circle Gas Station paymaster, batching multiple transactions into a single user operation, implementing passkey recovery using BIP-39 mnemonic phrases, building advanced onchain wallets with custom modules (multisig, subscriptions, session keys). Triggers on: modular wallet, smart account, MSCA, passkey authentication, WebAuthn, gasless, paymaster, Gas Station, bundler client, user operation, userOp, ERC-4337, ERC-6900, account abstraction, toCircleSmartAccount, toPasskeyTransport, toModularTransport, sendUserOperation, batch transactions, 2D nonce, passkey recovery, EIP-1193 provider.

5 red flags 5 cleared 1 not measured

Capabilities below are detected automatically by an open-source scanner that reads the skill's text and scripts (see how this is computed). Not measured means the scanner couldn't make a confident call — it is NOT a green check, and you should treat it as a possible red flag until a human or a stronger scanner has measured it.

5 Red flags things this skill can do that affect your security or funds

⚠
Requires private key you must hand over a private key, mnemonic, or wallet config
⚠
Requires hosted operator depends on a third-party hosted service to function
⚠
Mutable remote runtime runs remote code that can change behavior without a local diff
⚠
Can install code installs software at setup time (npx, pip, brew, etc.)
⚠
Can execute shell runs arbitrary shell commands on your machine

5 Cleared by scanner we scanned the skill's text & scripts and found no evidence of these

✓
Can move funds this skill can sign and send transactions on your behalf
✓
Uses remote install script setup pipes a remote shell script (curl | sh class)
✓
Can browse the web fetches arbitrary URLs at runtime
✓
Can write files writes to your local filesystem
✓
Can spawn sub-agents delegates to other skills or sub-agents

Ingredients (services this skill talks to)

External services this skill needs in order to work. The skill's behavior depends on these services being up, honest, and unchanged. Today we only show services we recognize from a curated list of ~50 well-known hosts (exchanges, RPC providers, data APIs); a complete dependency list — including every package, library, and binary the skill installs or imports — is on the roadmap.
