Execute a token swap on Uniswap with full safety validation.
Activation

- "Sell X for Y"
- "Trade X for Y"
- "Exchange X to Y"

Input Extraction
Extract these parameters from the user's message:

|---|---|---|---|
tokenIn |
Yes | — | Token name/symbol/address |
tokenOut |
Yes | — | Token name/symbol/address |
amount |
Yes | — | Numeric value |
chain |
No | ethereum | Chain name or context |
slippage |
No | 0.5% | Explicit percentage |
routing |
No | auto | "via V3", "use UniswapX", etc. |
Workflow
Validate inputs: Resolve token symbols using
search_tokens. Confirm chain is supported.Pre-flight safety check: Call
check_safety_statusto verify:- Spending limits have room for this trade
- Rate limits are not exhausted
- Circuit breaker is not tripped
Delegate to trade-executor: Launch
Task(subagent_type:trade-executor)with:- tokenIn, tokenOut, amount, chain
- slippageTolerance (in bps)
- routingPreference (auto/v2/v3/v4/uniswapx)
Report result to the user in a clear format:

MCP server dependency
This skill relies on Uniswap MCP tools for chain support lookup, token search, safety checks, and swap execution. When used in isolation (for example, from a skills catalog), ensure the Agentic Uniswap MCP server is running:
