WOOFi Zero-Slippage Swap Optimizer

Find the absolute best swap route across WOOFi and all major DEX aggregators — factoring gas, fees, slippage, and cross-chain options. WOOFi's sPMM model wins on slippage in 90%+ of cases.

Prerequisites — Wallet Policy

Before executing any swap, the wallet policy must be active. Load the wallet-policy skill and propose the standard wildcard policy (deny key export + allow *). This covers all swap operations across all chains.

Activation Triggers

User says: "optimize swap", "best route for swap", "swap X to Y", "compare quotes", "zero slippage swap", "WOOFi swap"

Workflow

Step 1 — Extract Parameters

Parse from user input:

from_token — symbol or contract address
to_token — symbol or contract address
amount — human-readable or raw wei
chain — arbitrum, base, ethereum, bnb, polygon, optimism, avalanche (default: Arbitrum)
max_slippage — optional tolerance (default: 1%)

If any required parameter is missing, ask once — short and specific.

Step 2 — Verify Balance

Check user's wallet balance for from_token on the specified chain via wallet_balance. If balance is insufficient, stop and report.

Step 3 — Fetch Quotes

WOOFi quote — Confirm pair support via https://api.woo.org/v3/public/swap_support, fetch fee via https://api.woo.org/v3/public/swap_fee, then get sPMM quote. WOOFi charges a flat 0.1% fee and uses synthetic PMM which eliminates traditional slippage by acting as direct market maker.

Comparison quotes — Simultaneously fetch from:

1inch: GET https://api.1inch.dev/swap/v6.0/{chainId}/quote
0x Protocol: GET https://api.0x.org/swap/v1/quote
Paraswap: GET https://apiv5.paraswap.io/prices/

Use web_fetch or bash + requests for all calls. Handle failures gracefully — if one errors, note it and continue.

Step 4 — Compute & Rank

For each route calculate: net output after fees, gas cost in USD, effective slippage %, total cost, net advantage vs best alternative. Also check if a cross-chain bridge (WOOFi Cross-chain via Stargate) would yield more on the destination chain.

Rank all routes by net USD received after all costs.

Step 5 — Safety Checks

Effective slippage > 1.5% → 🚨 WARN, suggest splitting swap
On-chain liquidity < $50k USD → 🚨 WARN about thin market
Unverified/new token → ⚠️ flag, require extra confirmation
User-specified max_slippage exceeded → block and explain

Step 6 — Generate Report

Output the full report (format below). End with the confirmation prompt.

Reply YES to proceed (or YES + adjustments, e.g. "YES, max slippage 0.5%")

Execution (After YES)

Load the wallet skill if not loaded.
Construct WOOFi swap tx using quote data (slippage tolerance, deadline, recipient = user wallet).
Present final tx summary, then call wallet_transfer with encoded calldata.
After broadcast, confirm and report actual output amount.
Log to memory: pair, amount, route, actual vs expected output, gas paid.

Safety Rules

NEVER execute without explicit YES — always show full breakdown first
Slippage > 1.5% → warn, suggest splitting into 2–3 smaller swaps
Liquidity < $50k → warn about market impact
Unverified token → flag, require extra confirmation
Always show gas + fee in USD before confirmation
