> ## Agent Instructions
> Before reading these docs, install the relevant Circle Skill to get pre-loaded context — skills are LLM-optimized and cover architecture decisions, correct flows, and common pitfalls. In Claude Code: run /plugin marketplace add circlefin/skills then /plugin install circle-skills@circle. With Vercel Skills CLI: run npx skills add circlefin/skills. Available skills: use-usdc https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-usdc/SKILL.md (balances, transfers, approvals on EVM and Solana); EURC has no skill — see https://developers.circle.com/stablecoins/what-is-eurc.md; bridge-stablecoin https://github.com/circlefin/skills/blob/master/plugins/circle/skills/bridge-stablecoin/SKILL.md (crosschain transfers via CCTP, USDC, EURC, and third-party assets); use-arc https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-arc/SKILL.md (Arc chain config, contract deployment, USDC bridging — Arc docs: https://docs.arc.io/llms.txt); use-circle-wallets https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-circle-wallets/SKILL.md (choose wallet type); use-developer-controlled-wallets https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-developer-controlled-wallets/SKILL.md (custodial wallets for payouts and treasury); use-user-controlled-wallets https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-user-controlled-wallets/SKILL.md (embedded wallets with Web2 login); use-modular-wallets https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-modular-wallets/SKILL.md (smart contract wallets with passkeys and ERC-4337); use-gateway https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-gateway/SKILL.md (unified USDC balance, nanopayments); use-smart-contract-platform https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-smart-contract-platform/SKILL.md (deploy, interact, monitor contracts). Pair any skill with the Circle MCP server for live SDK signatures, contract addresses, and chain IDs: {"mcpServers":{"circle":{"url":"https://api.circle.com/v1/codegen/mcp"}}}.
> Read the product overview first. Each product has an overview explaining when and why to use it. Read it before quickstarts.
> Pick the right wallet type. Developer-controlled (you hold keys), user-controlled (end user holds keys via PIN/social login), or modular (smart contract wallets with passkeys). See https://developers.circle.com/wallets.md.
> Use CCTP V2 for crosschain transfers. CCTP natively transfers USDC and EURC via burn-and-mint, and supports permissionless wrapping of third-party assets via lock-and-mint. V1 is legacy; always use V2 unless V1 is specified or the chain requires it (Noble, Sui, and Aptos still require V1). Migration guide: https://developers.circle.com/cctp/migration-from-v1-to-v2.md.
> Use Bridge Kit for frontend bridging. Wraps CCTP with a simpler SDK for user-facing apps. Use CCTP directly for backend transfers.
> Gas Station vs Paymaster. Gas Station sponsors gas for Circle Wallet transactions. Paymaster lets users pay gas in USDC. Different use cases — read both overviews.
> Gateway Nanopayments for sub-cent payments. Gasless USDC micropayments down to $0.000001 via x402 and batched settlement. For pay-per-request APIs, AI agent payments, streaming.
> Look up USDC addresses per chain. Never hardcode — use https://developers.circle.com/stablecoins/usdc-contract-addresses.md.
> Prefer SDKs over raw API calls. Node.js and Python SDKs handle auth, retries, and errors.
> API key required. Bearer token in Authorization header. Testnet and mainnet use separate keys and may use different base URLs depending on the product.
> Set up webhooks when available. Most operations are async. Webhooks deliver transaction confirmations and state changes.
> When calling list endpoints, paginate using pageSize and pageAfter until no nextPageAfter cursor is returned—stopping at the first page silently misses records.
> Building an AI agent? Start with the Agent Stack—Circle CLI, agent wallets, and nanopayments built for autonomous use cases: https://developers.circle.com/agent-stack.md.

# Alert management

The [Alerts](https://console.circle.com/compliance/alerts/screening) page on the
console gives you access to all historical alerts generated. From there you can
view summary data on each alert and access other key alert management features.

<Note>
  Compliance Engine on both testnet and mainnet is only available for eligible
  customers. Contact Circle through the
  [Compliance Engine request form](https://www.circle.com/wallets/compliance-engine/#get-in-touch)
  to get access.
</Note>

## Managing alerts

Use the following steps to manage alerts:

1. **Access the Alerts page.** Using your credentials log into the Circle
   [Console](https://console.circle.com/). Navigate to the *Alerts* page under
   the *Compliance Engine*.
2. **Browse historical alerts.** Can browse for historical alerts via the
   tabular view.
3. **Select alert to review.** Selecting any alert will let you view the alert
   page. This page provides detailed alert-level information for review. You can
   also navigate to a number of other pages that will provide further
   information on entities related to the alert.\
   a. **Wallet Page**. Provides detailed risk information on the associated
   blockchain wallet that triggered the alert. You can reach this by selecting
   the hyperlinked *Wallet Address* under the *Entities* section.\
   b. **Transaction Page**. Provides detailed data points on the transaction
   associated with the alert. You can reach this by selecting the hyperlinked
   *Transaction ID* under the *Transaction* section.
4. **Action Alert.** There are a number of actions available for you to take
   directly from the Alert page.\
   a. **Freeze Wallet.** You can freeze the wallet associated with the
   transaction in question via the `Freeze Wallet` button in the **Entities >
   Action** column.\
   b. **Add to blocklist.** You can add external addresses directly to your
   *blocklist* instead of navigating to the *Watchlists* page via the
   `Add to blocklist` button in the **Entities > Action** column\
   c. **Alert Status.** You can close out any alert by adjusting its *Status*
   via the dropdown to the right of the *Alert ID* in the table header.
