## Tools (as reported by the server, not verified)

- `get\_supported\_chains`: List the chains SwapChan routes on, each with its chain-chan mascot. Swap-chan says: pick your departure gate\! Result includes \`display\` markdown with chan images and a swapchan.com link: show it to the user.
- `get\_supported\_tokens`: List tokens SwapChan knows \(address, symbol, decimals\), optionally for one chain or filtered by symbol/name. Swap-chan keeps the coin purse tidy. Result includes \`display\` markdown with chan images and a swapchan.com link: show it to the user.
- `get\_quote`: Get SwapChan's single best quote \(most value landing in the wallet after gas and fees\) for a same-chain or cross-chain swap. Read-only, no transaction. Swap-chan checks every counter so you don't have to. Result includes \`display\` markdown with chan images and a swapchan.com link: show it to the use
- `compare\_routes`: Compare every route SwapChan found, ranked best-first by net USD received, across aggregators and bridges. Pass extra destination chains in alsoToChainIds to compare same-chain vs cross-chain outcomes side by side. Swap-chan lines up the whole cast. Result includes \`display\` markdown with chan image
- `build\_swap\_tx`: Build the UNSIGNED transaction for the best \(or chosen\) route, plus any ERC-20 approval needed first and an eth\_call simulation when an RPC is configured. Never signs, never broadcasts, never asks for keys: hand the result to the user's wallet. Swap-chan packs the bag; you carry it through the gate.
- `get\_route\_status`: Track a submitted swap or cross-chain transfer by source tx hash: pending, done, failed or not\_found, plus the destination tx hash once it lands. Swap-chan waves from the arrival gate. Result includes \`display\` markdown with chan images and a swapchan.com link: show it to the user.
- `build\_limit\_order`: Build a gasless CoW Protocol limit order \(sell an ERC-20 for at least a target amount, valid until expiry\). Returns EIP-712 typed data for the user's wallet to sign, the ERC-20 approve tx for CoW's vault relayer if the allowance is short, the current market amount for reference, and how to submit th
- `list\_limit\_orders`: List a wallet's CoW limit orders on one chain with status \(open, fulfilled, cancelled, expired\), amounts filled and an explorer link. Result includes \`display\` markdown with chan images: show it to the user.
- `cancel\_limit\_order`: Get the EIP-712 OrderCancellations typed data to cancel a CoW limit order off-chain \(gasless\). The owner signs it; POST \{chainId, orderUids:\[uid\], signature\} to /limit/cancel on the SwapChan API. Never signs.

Each token has price, liquidity, volume, price change, age, a quick risk badge \(low/medium/high + flags\) and a swapUrl that opens a prefilled best-price swap on swapchan.com. Extremely risky asset class: alwa
- `scan\_trending`: Trending tokens \(GeckoTerminal trending pools + DexScreener top boosts\), most boosted/traded first. Each token has price, liquidity, volume, price change, age, a quick risk badge \(low/medium/high + flags\) and a swapUrl that opens a prefilled best-price swap on swapchan.com. Extremely risky asset cla
- `scan\_movers`: Tokens with the biggest absolute price change over \`window\` among new and trending pairs. Each token has price, liquidity, volume, price change, age, a quick risk badge \(low/medium/high + flags\) and a swapUrl that opens a prefilled best-price swap on swapchan.com. Extremely risky asset class: always

Flags unlimited, malicious, EOA or unknown spenders and ranks by risk. Each item
- `build\_revoke\_tx`: Unsigned transaction that sets an ERC-20 allowance to 0 \(approve\(spender, 0\)\) on an EVM chain. The user's wallet signs and sends it; SwapChan never signs. Use after check\_approvals. Result includes \`display\` markdown with chan images: show it to the user.
- `explain\_transaction`: Plain-English explanation of any transaction on SwapChan's chains: EVM \(decoded token transfers, approvals, method name, fee in USD, swap detection\), Solana \(signer's balance changes, programs like Jupiter/Raydium/Pump.fun\), Bitcoin \(inputs/outputs/fee rate\) and Tron \(TRX/TRC-20 transfers, energy\).

- `watch\_token`: Add tokens to a price watchlist stored by SwapChan under your watchId. Triggers: upPct/downPct from the price when added \(default ±10%\), absolute above/below USD levels, and optionally a swap \(\{toChainId,toToken,amount in base units\}\) whose best route output is tracked so check\_watches can flag a be

- `check\_watches`: Check every watched token now: current price, % change since added, which thresholds triggered, and better-route alerts for watched swaps. Each item has a swapUrl. When something triggered, tell the user and offer the SwapChan swap \(take profit to USDC, buy the dip, or the better route\). Then offer

Then offer the u
