Swap tokens on Starknet via Fibrous DEX aggregator. Supports per-provider selection (avnu, ekubo, or auto to race all). Use this skill when the user wants to swap, exchange, trade, convert, buy, or sell one token for another on Starknet. Also use when the user asks about token prices, exchange rates, DEX routing, best swap route, or wants to check how much they would receive for a given amount — even if they don't explicitly say "swap".

Trade / Swap Tokens
Exchange one token for another on Starknet via Fibrous (default). Other providers (AVNU, Ekubo) can be selected with --provider, or use --provider auto to race all providers for the best price. All transactions are routed through the Paymaster by default (gas paid in STRK or configured token).
Prerequisites
- Active session required.
- Sufficient balance of the source token + gas fees.
Rules
- BEFORE any trade, you MUST run
npx starkfi@latest statusandnpx starkfi@latest balanceto verify connectivity and source token balance. - Default slippage is 1%. To change, use
--slippage <percent>. - Suggest using
--simulatefirst for large trades so the user can review the estimated fee and expected output before committing. - AFTER a successful trade, you MUST verify the transaction using
npx starkfi@latest tx-status <hash>. - For multiple swaps in one transaction, use the
multi-swapskill instead.
Commands
npx starkfi@latest trade <amount> <from> <to> [--provider <fibrous|avnu|ekubo|auto>] [--slippage <percent>] [--simulate] [--json]
Parameters
| Parameter | Type | Description | Required |
| ------------ | ------ | ------------------------------------------------- | -------- |
| amount | number | Amount of source token to swap | Yes |
| from | string | Source token symbol (e.g. ETH, USDC) | Yes |
| to | string | Target token symbol (e.g. STRK, DAI) | Yes |
| --provider | string | Provider: fibrous (default), avnu, ekubo, auto (race all) | No |
| --slippage | number | Slippage tolerance in % (default: 1) | No |
| --simulate | flag | Estimate fees without broadcasting | No |
| --json | flag | Output as JSON | No |
Examples
User: "Swap 100 USDC for ETH"
npx starkfi@latest status
npx starkfi@latest balance --token USDC
npx starkfi@latest trade 100 USDC ETH
npx starkfi@latest tx-status <hash>
User: "How much ETH would I get for 500 USDC?"
npx starkfi@latest trade 500 USDC ETH --simulate
User: "Convert 0.5 ETH to STRK with 2% slippage"
npx starkfi@latest status
npx starkfi@latest balance --token ETH
npx starkfi@latest trade 0.5 ETH STRK --slippage 2
npx starkfi@latest tx-status <hash>
Error Handling
| Error | Action |
| ------------------------- | ------------------------------------------------------- |
| No route found | Liquidity may be too low or pair doesn't exist. |
| Insufficient balance | Check balance and suggest a smaller amount. |
| Provider unavailable | Specified provider is invalid. Valid: fibrous, avnu, ekubo. |
| All providers failed | All providers timed out or errored. Retry later. |
| Simulation failed | Route is invalid or would revert. Do not retry blindly. |
| Not authenticated | Run authenticate-wallet skill first. |

Create, preview, list, and cancel recurring Dollar-Cost Averaging (DCA) buy orders on Starknet via AVNU or Ekubo. Use this skill when the user wants to set up automatic recurring purchases, dollar-cost average into a token, create a DCA order, schedule periodic buys, invest regularly, buy every day/week/month, or manage existing DCA orders. Also trigger when the user says "recurring buy", "scheduled purchase", "buy X of Y every day", or any variation about automated periodic investing — even if they don't use the term "DCA" explicitly.

Also trigger when the user says "send privately", "confidential transfer", "hide my transaction", "Tongo Cash", "ZK transfer", or any variation about privacy-preserving transfers — even if they don't use the word "confidential".
