--- name: bridge-tokens description: Bridge tokens from one chain to another without swapping. Simplified cross-chain transfer where the output token is the same as the input token. Use when the user wants to move tokens between chains. model: opus allowed-tools: [Task(subagent_type:cross-chain-executor), mcp__uniswap__getSupportedChains, mcp__uniswap__getTokenInfo] --- # Bridge Tokens ## Overview Bridges tokens from one chain to another — a simplified cross-chain operation where the token stays the same (e.g., USDC on Ethereum to USDC on Base). Delegates to the `cross-chain-executor` agent with `tokenOut = tokenIn` to streamline the workflow. This is the simpler sibling of `cross-chain-swap`. Use this when the user just wants to move tokens, not swap them. ## When to Use Activate when the user asks: - "Bridge 1000 USDC from Ethereum to Base" - "Move my ETH to Arbitrum" - "Transfer USDC to Optimism" - "Send tokens to another chain" - "Bridge tokens" - "Move all my USDC from Polygon to Base" ## Parameters | Parameter | Required | Default | Description | | ---------------- | -------- | ---------- | ----------------------------------------------------- | | token | Yes | — | Token symbol or address to bridge | | amount | Yes | — | Amount to bridge (human-readable) | | sourceChain | Yes | — | Source chain name (e.g., "ethereum") | | destChain | Yes | — | Destination chain name (e.g., "base") | | recipient | No | Same wallet| Recipient address on destination chain | ## Workflow 1. **Extract parameters** from the user's request. Identify: - Which token to bridge. - The amount. - Source and destination chains. - Resolve the same token's address on both chains via `mcp__uniswap__getTokenInfo`. 2. **Validate inputs**: - Verify both chains are supported via [REDACTED_SECRET]. - Verify the token exists on both chains. - If source and destination chain are the same: inform the user no bridge is needed. 3. **Delegate to cross-chain-executor**: Invoke `Task(subagent_type:cross-chain-executor)` with: - tokenIn = token (on source chain). - tokenOut = same token (on destination chain). - amount, sourceChain, destChain, recipient. - The agent handles quoting, safety, execution, monitoring, and confirmation. 4. **Present results**: Format the bridge report for the user, highlighting: - Amount sent and received (should be very close, minus bridge fee). - Bridge fee. - Settlement time. ## Output Format ```text Bridge Complete Token: USDC Sent: 1,000.00 USDC on Ethereum Received: 999.50 USDC on Base Bridge Fee: 0.50 USDC ($0.50) Settlement: 1 min 48 sec Source Tx: 0xabc...123 Bridge ID: 0x789...abc Dest Tx: 0xdef...456 Risk: LOW | Safety: APPROVED ``` ## Important Notes - Bridge operations transfer the same token between chains. The received amount will be slightly less due to bridge fees. - Settlement times vary by chain pair (typically 1-10 minutes). - Not all tokens are bridgeable between all chains. The executor will check availability. - For moving tokens AND swapping to a different token, use `cross-chain-swap` instead. ## Error Handling | Error | User-Facing Message | Suggested Action | | ---------------------------- | ---------------------------------------------------------------- | -------------------------------------- | | Token not available on dest | "[Token] is not available on [destChain]." | Use cross-chain-swap to swap to a native token | | Same chain | "Source and destination are the same chain. No bridge needed." | No action needed | | Unsupported chain | "Chain [name] is not supported." | Check supported chains | | Safety veto | "This bridge was blocked by safety checks: [reason]." | Reduce amount or check configuration | | Bridge stuck | "Bridge settlement is delayed. Monitoring continues." | Wait — recovery instructions provided | | Insufficient balance | "Not enough [token] on [chain]." | Check balance and reduce amount |

content: # Bridge Tokens

Bridge tokens from one chain to another without swapping. The same token is sent on the source chain and received on the destination chain.

## Installation

Install into Claude Code or Cursor with:

```bash
npx skills add https://github.com/wpank/Agentic-Uniswap/tree/main/.ai/skills/bridge-tokens
```

Or via Clawhub:

```bash
npx clawhub@latest install bridge-tokens
```

## When to use

Use this skill when:

- You want to **move a token from one chain to another** without changing it (e.g., USDC Ethereum → USDC Base).
- You need **simple bridging only**, not a swap plus bridge.
- You want safety checks around **bridge choice, limits, and completion status**.

## Example prompts

- "Bridge 1,000 USDC from Ethereum to Base."
- "Move my WETH from Arbitrum to Optimism without swapping."
- "Bridge 500 USDT from Polygon to Ethereum and confirm when it arrives."
