Token Swap Skill

Execute token swaps on Uniswap (V2/V3) and PancakeSwap (V2/V3) across multiple EVM chains.

Overview

Swap tokens using dedicated DEX tools that automatically compare V2 and V3 quotes to find the best price. Uses the active wallet for signing transactions.

Supported DEXes

BSC: PancakeSwap V2 + V3
Ethereum: Uniswap V2 + V3
Polygon: QuickSwap V2 + Uniswap V3
Arbitrum: Uniswap V2 + V3
Optimism: Uniswap V3
Base: Uniswap V3

Tools Used

```
swap_get_quote
```
- Get best swap quote across V2/V3 with estimated output and price impact
```
swap_execute
```
- Execute the swap (auto-approves token spending if needed)
```
swap_check_allowance
```
- Check if token is already approved for the router
```
swap_supported_dexes
```
- List available DEXes and fee tiers for a network
```
get_erc20_token_info
```
- Look up token name, symbol, decimals by contract address

Workflow

User requests a swap → call
```
swap_get_quote
```
with tokenIn, tokenOut, amountIn
Present quote: input amount, estimated output, minimum output, slippage, DEX name, version
If price impact is high or slippage > 1%, warn the user
Ask user for explicit confirmation before proceeding
Call
```
swap_execute
```
with same parameters

Security Rules

ALWAYS show the swap quote before executing
ALWAYS warn if estimated output seems low (possible low liquidity)
NEVER execute swaps without explicit user confirmation
Default slippage: 0.5% — warn if user sets above 3%
For large swaps, suggest splitting into multiple smaller trades
Run
```
security-check
```
on the target token before executing a swap to detect honeypots and high taxes

V3 Fee Tiers

When using V3, the fee tier affects which liquidity pool is used:

0.01% (100) — stablecoin pairs
0.05% (500) — stable/common pairs
0.3% (3000) — most common, default
1% (10000) — exotic pairs

The tool auto-selects the best fee tier by default.

Example Interactions

User: "Swap 1 BNB for USDT on BSC" → Call

swap_get_quote

with tokenIn="native", tokenOut="0x55d398326f99059fF775485246999027B3197955", amountIn="1" → Show: "PancakeSwap V3: 1 BNB → ~590.23 USDT (min: 587.28 USDT, 0.5% slippage)" → After confirmation: call

swap_execute

User: "What would I get for swapping 100 USDT to ETH on Ethereum?" → Call

swap_get_quote

only, display result without executing

User: "What DEXes work on Arbitrum?" → Call

swap_supported_dexes

with network="arbitrum"
