Multi-chain DEX swap aggregation with quote, approval, and execution across 500+ liquidity sources.
Works with
Supports 20+ blockchains including Solana, Ethereum, Base, BSC, Arbitrum, Polygon, and XLayer with automatic chain name resolution
Generates swap transaction data with autoSlippage optimization, price impact assessment, and MEV protection for large trades
Handles EVM token approvals with merged approve+swap flow to reduce transaction steps; native tokens skip approval automatically
AI-first code editor with Composer
Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionokx-dex-swapExecute the skills CLI command in your project's root directory to begin installation:
Fetches okx-dex-swap from okx/onchainos-skills and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate okx-dex-swap. Access via /okx-dex-swap in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

| # | Command | Description |
|---|---|---|
| 1 | onchainos swap chains |
Get supported chains for DEX aggregator |
| 2 | onchainos swap liquidity --chain <chain> |
Get available liquidity sources on a chain |
| 3 | onchainos swap approve --token ... --amount ... --chain ... |
Get ERC-20 approval transaction data (advanced/manual use) |
| 4 | onchainos swap quote --from ... --to ... --readable-amount ... --chain ... |
Get swap quote (read-only price estimate). No --slippage param. |
| 5 | onchainos swap execute --from ... --to ... --readable-amount ... --chain ... --wallet ... [--slippage <pct>] [--gas-level <level>] [--mev-protection] |
One-shot swap: quote → approve (if needed) → swap → sign & broadcast → txHash. |
| 6 | onchainos swap swap --from ... --to ... --readable-amount ... --chain ... --wallet ... [--slippage <pct>] |
Calldata only: returns unsigned tx data. Does NOT sign or broadcast. |

Display: expected output, gas, price impact, routing path. Check isHoneyPot and taxRate — surface to user. Perform MEV risk assessment (see MEV Protection).

CLI handles approve (if needed) + sign + broadcast internally.
Returns: { approveTxHash?, swapTxHash, fromAmount, toAmount, priceImpact, gasUsed }
If swap execute returns an error, it may be caused by a preceding approval transaction that has not yet been confirmed on-chain. Handle as follows:
| Chain | Typical Wait |
|---|---|
| Ethereum | ~15 s |
| BSC | ~5 s |
| Arbitrum / Base | ~3 s |
| XLayer | ~3 s |
| Other EVM | ~10 s (conservative default) |
token advanced-info; warn if devRugPullTokenCount > 0 or tokenTags contains lowLiquidity.Enabled only when the user has explicitly authorized automated execution. Three mandatory rules:
Use business-level language: "Swap complete" / "Approval and swap complete". Do NOT say "Transaction confirmed on-chain" / "Successfully broadcast" / "On-chain success".
Suggest follow-up: explorer link for swapTxHash, check new token price, or swap again.

💡 Pro Tips
✓ Use when
Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.
✗ Avoid when
Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.
