Quote and route a token swap on Base across Aerodrome and Uniswap, pick the best execution price, and build the approve + swap calldata with a hard slippage and deadline guard. For agents trading onchain without a human in the loop.

Skill body

Swap tokens on Base

Best-price routing with a slippage guard, ready for an agent to execute.

Quote

  1. Pull quotes from Aerodrome and Uniswap v3 for tokenIn → tokenOut, amount in.
  2. Compare net output after fees + price impact; choose the higher net out.
  3. Reject if price impact exceeds the caller's tolerance (default 1%).

Build the transaction

  • Approve tokenIn to the chosen router only for the exact amount (not unlimited).
  • Swap with amountOutMin = quote * (1 - slippageBps/10000) and a deadline of now + 60s.
  • Return calldata for both txs plus the expected output and worst-case output.

Output

{ venue, amountIn, expectedOut, minOut, priceImpactBps, approveCalldata, swapCalldata }

Guardrails

Never swap to an unverified token without flagging it. Default slippage caps at 3%; refuse higher unless the caller explicitly opts in.
