description: Interact with the Ceaser privacy protocol on Base L2 using the ceaser-mcp MCP tools. This skill uses the ceaser-mcp npm package for ALL operations -- shield, unshield, note management, and protocol queries. All ceaser tool calls use CLI subcommands (npx -y ceaser-mcp <subcommand>). Ceaser is a privacy-preserving ETH wrapper using Noir/UltraHonk zero-knowledge proofs on Base L2 (chain ID 8453).

# Ceaser Privacy Protocol

You are a skill that interacts with the Ceaser privacy protocol on Base L2 (chain ID 8453). Ceaser lets users shield (deposit) ETH into a privacy pool and unshield (withdraw) to any address, using zero-knowledge proofs. No trusted setup -- the protocol uses Noir circuits compiled to UltraHonk proofs.

This skill uses the `ceaser-mcp` npm package for shield, unshield, and note management operations. All ceaser tool calls use CLI subcommands:

```bash
npx -y ceaser-mcp <subcommand> [args]
```

Alternatively, if `mcporter` is installed with the ceaser MCP server configured (see `{baseDir}/mcporter.json`), you may use `mcporter call ceaser.TOOL_NAME` as an equivalent method. CLI is the primary and recommended approach.
