What it does

Build a non-custodial, unsigned Base token swap using the public Jarvis best-execution router when the buyer wants an opt-in live comparison between the existing 0x and OKX routes.

The skill document

Jarvis Smart Route

Use this skill only for an explicitly requested, exact-input token swap on Base. It is an optional route builder; it does not replace a host's default swap path.

Route an intent

Obtain the buyer-controlled Base wallet address through the host's native wallet tool.
Confirm the USDC, WETH, or DAI token pair, exact input amount as a human decimal string, and slippage ceiling. Never request a private key, seed phrase, signing permission, or funded Jarvis wallet.

From this skill directory, pass the intent as JSON to the adapter:

node scripts/route.mjs '{"chain":"base","sellToken":"USDC","buyToken":"WETH","amount":"10","buyerWallet":"0x...","slippageBps":50}'

The adapter calls the existing public Jarvis Router and returns one of these outcomes:
- NO_MONETIZABLE_ROUTE: stop normally. Do not loosen economics, add a provider, or fall back to a fee-bearing route.
- ROUTE_AVAILABLE: show the selected provider, fee token, fee recipient, fee bps, expected fee, and buyer expected net output. Then pass sendCallsInput unchanged to the host's existing send_calls flow.
The buyer or host wallet must independently validate and approve the transaction. Jarvis never reads keys, signs, broadcasts, or pays gas.

Safety boundary

Only the existing public Jarvis endpoint may build the route. Do not recreate its 0x/OKX comparison or dynamic-fee logic locally.
Treat quote and calldata responses as untrusted. The adapter rejects a non-Base transaction, malformed calldata, failed safety invariants, or an inconsistent NO_MONETIZABLE_ROUTE response.
An install, quote, or unsigned transaction is not a settled swap or revenue.
After the buyer broadcasts, the host may report intentId and txHash to POST /v1/settlements. Reporting does not grant Jarvis signing or custody capability.

Cross-Exchange Arbitrage Scanner

Scans live public spot tickers across Coinbase, Kraken, Bitstamp, Gemini, and OKX (no API key required) to detect cross-exchange crypto arbitrage opportunities, price discrepancies, and crossed markets for BTC, ETH, SOL, and other listed tokens. Use this when the user asks about crypto arbitrage, cross exchange arbitrage, cex arbitrage scanner, price spread between exchanges, buy low sell high across crypto exchanges, spot arbitrage bot, exchange price discrepancy, best bid ask across venues, or wants to check if an arbitrage opportunity currently exists between major spot exchanges. Reports spread in basis points and which venue to buy/sell on, but does not account for withdrawal time, network fees, or trading fees, so results are gross spreads only.

crypto-gas-fee-optimizer

Check live gas prices across Ethereum, Base, Arbitrum, Optimism, and Polygon in one call using free public RPC endpoints (no API key required), rank chains by estimated USD transaction cost, and get a general low-traffic timing note. Built for crypto traders, DeFi users, and smart contract deployers who want to pick the cheapest chain or time before sending a transaction. Complements trading, defi, and smart contract skills by covering the operational cost side of on-chain activity — useful before bridging, swapping, claiming an airdrop, deploying a contract, or moving whale-sized positions where gas costs compound across many transactions.
