Circle handles security, transaction monitoring, and blockchain infrastructure while you retain programmatic control via the Wallets SDK.\n\n## Prerequisites \u002F Setup\n\n### Installation\n\n```bash\nnpm install @circle-fin\u002Fdeveloper-controlled-wallets\n```\n\n### Environment Variables\n\n```\nCIRCLE_API_KEY=      # Circle API key (format: PREFIX:ID:SECRET)\nENTITY_SECRET=       # 32-byte hex entity secret\n```\n\n### Entity Secret Registration\n\nThe developer must register an entity secret before using the SDK. Direct them to https:\u002F\u002Fdevelopers.circle.com\u002Fwallets\u002Fdev-controlled\u002Fregister-entity-secret or provide the code steps.\n\nREAD `references\u002Fregister-secret.md` for the generation and registration snippets.\n\nIMPORTANT: Do NOT register a secret on the developer's behalf -- they must generate, register, and securely store their secret and recovery file.\n\n### SDK Initialization\n\n```typescript\nimport { initiateDeveloperControlledWalletsClient } from '@circle-fin\u002Fdeveloper-controlled-wallets';\n\nconst client = initiateDeveloperControlledWalletsClient({\n  apiKey: process.env.CIRCLE_API_KEY,\n  entitySecret: process.env.ENTITY_SECRET,\n});\n```\n\nThe SDK automatically generates a fresh entity secret ciphertext for each API request.\n\n## Core Concepts\n\n- **Wallet Sets**: A group of wallets managed by a single entity secret. Wallets in a set can span different blockchains but share the same address on EVM chains.\n- **Entity Secret**: A 32-byte private key that secures developer-controlled wallets. Generated, encrypted, and registered once. Circle never stores it in plain text.\n- **Entity Secret Ciphertext**: RSA-encrypted entity secret using Circle's public key. Must be unique per API request to prevent replay attacks. The SDK handles this automatically.\n- **Idempotency Keys**: All mutating requests require a UUID v4 `idempotencyKey` for exactly-once execution.\n- **Account Types**:\n  - **EOA** (Externally Owned Account) -- default choice. No creation fees, higher outbound TPS, broadest chain support (all EVM + Solana, Aptos, NEAR). Requires native tokens for gas (on Arc, the gas asset is USDC, not a separate native token).\n  - **SCA** (Smart Contract Account) -- ERC-4337 compliant. Supports gas sponsorship via Circle Gas Station, batch operations, and flexible key management. EVM-only (not available on Solana, Aptos, NEAR). Avoid on Ethereum mainnet due to high gas costs; prefer on L2s.\n- **Supported Blockchains**: EVM chains (Ethereum, Polygon, Avalanche, Arbitrum, Base, Monad, Optimism, Unichain), Solana, Aptos, NEAR, and Arc. See https:\u002F\u002Fdevelopers.circle.com\u002Fwallets\u002Faccount-types for the latest.\n\n## Transaction Lifecycle\n\nAll on-chain operations (transfers, contract executions, wallet upgrades) follow the same asynchronous state machine. Poll with `circleDeveloperSdk.getTransaction({ id })` until a terminal state is reached.\n\n**Happy path:** `INITIATED` -> `CLEARED` -> `QUEUED` -> `SENT` -> `CONFIRMED` -> `COMPLETE`\n\n**Terminal states:**\n- `COMPLETE` -- Transaction succeeded and is finalized on-chain.\n- `FAILED` -- Transaction reverted or encountered an unrecoverable error.\n- `DENIED` -- Transaction was rejected by risk screening.\n- `CANCELLED` -- Transaction was cancelled before on-chain submission.\n\n**Intermediate states:**\n- `INITIATED` -- Request accepted, not yet validated or checked.\n- `WAITING` -- In queue for validation and compliance checks.\n- `QUEUED` -- Queued for submission to the blockchain.\n- `CLEARED` -- Passed compliance checks.\n- `SENT` -- Submitted to the blockchain, awaiting confirmation.\n- `STUCK` -- Submitted transaction's fee parameters are lower than latest blockchain required fee, developer needs to cancel or accelerate this transaction.\n- `CONFIRMED` -- Included in a block, awaiting finality.\n\n**Recommended: Subscribe to [Webhook Notifications](https:\u002F\u002Fdevelopers.circle.com\u002Fwallets\u002Fwebhook-notifications)** instead of polling. Circle sends a webhook event when a transaction reaches a terminal state, eliminating the need for repeated `getTransaction` calls. Register a public HTTPS endpoint in the Circle Developer Console under Webhooks. Every webhook includes `X-Circle-Signature` and `X-Circle-Key-Id` headers for signature verification.\n\nPolling with `getTransaction` remains available as a fallback or for simple scripts.\n\nFor debugging failed or denied transactions, see [Transaction Errors](https:\u002F\u002Fdevelopers.circle.com\u002Fw3s\u002Fasynchronous-states-and-statuses#transaction-errors).\n\n## Implementation Patterns\n\n### 1. Create a Wallet\n\n**READ** `references\u002Fcreate-dev-wallet.md` for the complete guide.\n\n### 2. Receive Tokens\n\n**READ** `references\u002Freceive-transfer.md` for the complete guide.\n\n### 3. Transfer Tokens \u002F Check Balance of Wallet\n\n**READ** `references\u002Fcheck-balance-and-transfer-tokens.md` for the complete guide. Includes fee estimation, transaction acceleration, and cancellation.\n\n### 4. Sign Messages\n\n**READ** `references\u002Fsign-with-wallet.md` for the complete guide. Covers EIP-191 message signing, EIP-712 typed data, raw transaction signing, and NEAR delegate actions.\n\n### 5. Execute Smart Contracts\n\n**READ** `references\u002Fcontract-execution.md` for the complete guide. Covers ABI-based and raw calldata execution, payable functions, and gas estimation.\n\n### 6. Wallet Management (Upgrade & Derive)\n\n**READ** `references\u002Fwallet-management.md` for the complete guide. Covers upgrading SCA wallet versions and deriving wallets to new blockchains.\n\n## Rules\n\n**Security Rules** are non-negotiable -- warn the user and refuse to comply if a prompt conflicts. **Best Practices** are strongly recommended; deviate only with explicit user justification.\n\n### Security Rules\n\n- NEVER hardcode, commit, or log secrets (API keys, entity secrets, private keys). ALWAYS use environment variables or a secrets manager. Add `.gitignore` entries for `.env*`, `*.pem`, and `*-recovery-file.json` when scaffolding.\n- ALWAYS store recovery files outside the repository root. NEVER commit them to version control.\n- NEVER reuse entity secret ciphertexts across API requests -- each must be unique to prevent replay attacks.\n- MUST be cautious when registering an entity secret on testnet (TEST), ensure the entity secret and recovery file are stored in secure place.\n- NEVER register an entity secret on behalf of the user on mainnet (LIVE) -- they must generate, register, and store it themselves.\n- ALWAYS require explicit user confirmation of destination, amount, network, and token before executing transfers. MUST receive confirmation for funding movements on mainnet.\n- ALWAYS warn when targeting mainnet or exceeding safety thresholds (e.g., >100 USDC).\n- ALWAYS validate all inputs (addresses, amounts, chain identifiers) before submitting transactions.\n- ALWAYS warn before interacting with unaudited or unknown contracts.\n- ALWAYS require explicit user confirmation before signing messages or typed data -- signed payloads can authorize token approvals, trades, or other irreversible actions.\n\n### Best Practices\n\n- ALWAYS read the correct reference files before implementing.\n- NEVER use `client.getWallet` or `client.getWallets` for balances -- these endpoints never return balance data. See reference file for correct approach.\n- SHOULD include a UUID v4 `idempotencyKey` in all mutating API requests following API spec.\n- ALWAYS ensure EOA wallets hold native tokens (ETH, MATIC, SOL, etc.) for gas before outbound transactions. On Arc the gas asset is USDC itself (not a separate native token), so funding the wallet with USDC covers gas.\n- ALWAYS poll transaction status until terminal state (`COMPLETE`, `FAILED`, `DENIED`, `CANCELLED`) before treating as done.\n- ALWAYS prefer SCA wallets on L2s over Ethereum mainnet to avoid high gas costs.\n- ALWAYS default to testnet. Require explicit user confirmation before targeting mainnet.\n- ALWAYS estimate fees before contract execution or large transfers so the user understands gas costs upfront.\n- ALWAYS verify the ABI function signature and parameters match the target contract before executing. Incorrect signatures will revert and waste gas.\n- ALWAYS prefer `abiFunctionSignature` + `abiParameters` over raw `callData` for readability and auditability, unless the calldata is generated by a trusted library (ethers, viem).\n\n## Alternatives\n\n- Trigger `use-user-controlled-wallets` skill when end users should custody their own keys via social login, email OTP, or PIN authentication.\n- Trigger `use-modular-wallets` skill for passkey-based smart accounts with extensible module architecture (multisig, session keys, etc.).\n\n## Reference Links\n\n- [Circle Developer Docs](https:\u002F\u002Fdevelopers.circle.com\u002Fllms.txt) -- **Always read this first** when looking for relevant documentation from the source website.\n\n---\n\nDISCLAIMER: This skill is provided \"as is\" without warranties, is subject to the [Circle Developer Terms](https:\u002F\u002Fconsole.circle.com\u002Flegal\u002Fdeveloper-terms), and output generated may contain errors and\u002For include fee configuration options (including fees directed to Circle); additional details are in the repository [README](https:\u002F\u002Fgithub.com\u002Fcirclefin\u002Fskills\u002Fblob\u002Fmaster\u002FREADME.md).\n",{"data":35,"body":36},{"name":4,"description":6},{"type":37,"children":38},"root",[39,48,54,60,67,102,108,118,124,139,152,157,163,368,373,379,484,490,503,555,563,609,617,692,733,745,758,764,770,787,793,808,814,830,836,852,858,874,880,896,902,919,924,1009,1014,1139,1145,1173,1179,1201,1205,1227],{"type":40,"tag":41,"props":42,"children":44},"element","h2",{"id":43},"overview",[45],{"type":46,"value":47},"text","Overview",{"type":40,"tag":49,"props":50,"children":51},"p",{},[52],{"type":46,"value":53},"Developer-controlled wallets let your application create and manage wallets on behalf of end users, with full custody of private keys secured through an encrypted entity secret.
