What it does
Use Circle Wallets is an agent skill from circlefin/skills. Choose and implement the right Circle wallet type for your application. Compares developer-controlled, user-controlled, and modular (passkey) wallets across custody model, key management, account types, blockchain support, and use cases. Use whenever blockchain wallet integrations are required for onchain application development. Triggers on: which wallet, choose wallet, wallet comparison, EOA vs SCA vs Modular Wallet, custody model, programmable wallets.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/example-scenarios.md`).
It sits in Security, covering Cryptography. It works with Circle USDC. The repository describes itself as: Circle's open source skills for AI-assisted development. The licence is Apache-2.0.
When your agent uses it
- Blockchain wallet integrations are required for onchain application development
- Wallet comparison
- EOA vs SCA vs Modular Wallet
- Programmable wallets
Example prompts
- “/use-circle-wallets”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Who controls the keys / who is the custodian?
- Auth method?
- Account type?
- Chain check (Modular wallets)
What it can do on your machine
Read from SKILL.md and the folder at commit 58ab864. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
developers.circle.comconsole.circle.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Use Circle Wallets loads about 1.3k tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 120 tokens; SKILL.md has 565 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Choose and implement the right Circle wallet type for your application. Compares developer-controlled, user-controlled, and modular (passkey) wallets across custody model, key management, account types, blockchain support, and use cases. Use whenever blockchain wallet integrations are required for onchain application development. Triggers on: which wallet, choose wallet, wallet comparison, EOA vs SCA vs Modular Wallet, custody model, programmable wallets.
Overview
Circle offers three wallet types -- developer-controlled, user-controlled, and modular -- each with different custody models, account types, key management, and capabilities. This skill helps you pick the right one.
Quick Comparison
| Developer-Controlled | User-Controlled | Modular (Passkey) | |
|---|---|---|---|
| Custody | Developer | User | User |
| Auth | API key + entity secret (backend) | Social login / email OTP / PIN | Passkey (WebAuthn) |
| Account types | EOA, SCA | EOA, SCA | Modular Wallet SCA (ERC-6900) |
| Gas sponsorship | SCA via Circle Paymaster | SCA via Circle Paymaster | Circle Paymaster or third-party paymaster |
| Custom modules | No | No | Yes |
| Architecture | Backend SDK only | Backend + frontend SDKs | Frontend SDK only |
Decision Guide
For the latest supported account types on different blockchains: https://developers.circle.com/wallets/account-types
For the latest supported features on different blockchains: https://developers.circle.com/wallets/supported-blockchains
- Who controls the keys / who is the custodian?
- Developer controls -> Developer-controlled wallets -> step 3
- End user controls -> step 2
- Auth method?
- Passkey (WebAuthn biometric) with extensible modules -> Modular wallets -> step 4
- Social login, email OTP, or PIN -> User-controlled wallets -> step 3
- Account type?
- Solana, Aptos, or NEAR -> EOA (only option)
- Ethereum mainnet -> EOA (SCA gas costs prohibitive, Modular Wallet not supported)
- L2 (Arbitrum, Base, Polygon, Optimism, etc.) -> EOA if max TPS needed; SCA if gas sponsorship or batching needed; Modular Wallet if passkey or other modular plugins needed
- Chain check (Modular wallets)
- Supported: Arbitrum, Avalanche, Base, Monad, Optimism, Polygon, Unichain
- NOT supported: Ethereum, Solana, Aptos, NEAR. Fall back to user-controlled wallets with SCA.
Example scenarios
READ references/example-scenarios.md for common scenarios mapped to a wallet-type decision and the skill to implement it.
Implementation Patterns
Once a wallet type has been determined, TRIGGER the corresponding skill:
- Developer-controlled ->
use-developer-controlled-walletsskill - User-controlled ->
use-user-controlled-walletsskill - Modular (Passkey) ->
use-modular-walletsskill
Strict Rules
- ALWAYS select the wallet type before starting implementation using the comparison table and decision guide above.
- ALWAYS use EOA on Ethereum mainnet (SCA gas prohibitive, Modular Wallet not supported) and on Solana, Aptos, NEAR (SCA/Modular Wallet not available).
- ALWAYS prefer SCA or Modular Wallet on L2 chains (Arbitrum, Base, Polygon, Optimism, etc.) when gas sponsorship or batch operations are needed.
- NEVER mix wallet types in a single user flow -- pick one and use its corresponding skill.
- ALWAYS delegate to the specific wallet skill (
use-developer-controlled-wallets,use-user-controlled-wallets, oruse-modular-wallets) for implementation.

Safety & Escalation
This skill only recommends a wallet type; it performs no on-chain writes, transfers, signing, or key operations itself. Every side effect — creating a wallet, signing, sending funds, deploying a contract — happens in the delegated implementation skill, which owns confirmation for those actions.
Escalate before delegating when:
- Missing context — the custody model, target chain, or auth method is unclear. Ask the user; do not guess a wallet type.
- Missing access — the user lacks a Circle account, an API key + entity secret (developer-controlled), or a configured passkey domain (modular). Direct them to set that up first.
- Unsafe effects — the selected path will move real funds on mainnet. Flag that the implementation skill must obtain explicit user confirmation before any mainnet transaction.
- User approval — confirm the chosen wallet type with the user before handing off to the implementation skill.
