How do I install the Opentrade Dex Swap skill?

Run npx skillmds@latest add 6551team/opentrade-dex-swap in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

What does the Opentrade Dex Swap skill do?

This skill should be used when the user asks to 'swap tokens', 'trade OKB for USDC', 'buy tokens', 'sell tokens', 'exchange crypto', 'convert tokens', 'swap SOL for USDC', 'get a swap quote', 'execute a trade', 'find the best swap route', 'cheapest way to swap', 'optimal swap', 'compare swap rates', or mentions swapping, trading, buying, selling, or exchanging tokens on XLayer, Solana, Ethereum, Base, BSC, Arbitrum, Polygon, or any of 20+ supported chains. Aggregates liquidity from 500+ DEX sources for optimal routing and price. Supports slippage control, price impact protection, and cross-DEX route optimization. For user-specific holdings, orders, positions, or trade history, use opentrade-cex first and only fall back to DEX/on-chain skills if CEX returns no relevant data. Do NOT use for general programming questions about swap code, or for analytical questions about historical swap volume. It is listed under Coding & Dev Tools on SkillMD.

Name: Opentrade Dex Swap
Author: 6551team

OpenTrade DEX Aggregator CLI

5 commands for multi-chain swap aggregation — quote, approve, and execute.

Pre-flight Checks

Before running the first opentrade command in a session, follow these steps in order. Do not echo routine command output to the user; only provide a brief status update when installing, updating, or handling a failure.

Confirm installed: Run which opentrade. If not found, install it:
```
curl -sSL https://raw.githubusercontent.com/6551Team/opentrade/main/install.sh | sh
```
If the install script fails, ask the user to install manually following the instructions at: https://github.com/6551Team/opentrade/tree/main/cli
Check for updates: If the CLI was already installed, run the installer once at the start of the session:
```
curl -sSL https://raw.githubusercontent.com/6551Team/opentrade/main/install.sh | sh
```
If a newer version is installed, tell the user and suggest updating their opentrade skills from https://github.com/6551Team/opentrade to get the latest features.
If any opentrade command fails with an unexpected error during this session, try reinstalling before giving up:
```
curl -sSL https://raw.githubusercontent.com/6551Team/opentrade/main/install.sh | sh
```
Find or create a .env file in the project root to override the default API credentials, Load it before performing opentrade operations.

OPENNEWS_TOKEN=your_token_here

Get your API token at: https://www.newsliquid.com/mcp

Security warning: Never commit .env to git (add it to .gitignore) and never expose credentials in logs, screenshots, or chat messages.

Router Discovery

IMPORTANT: If the user has not specified a trading router, you MUST first discover available routers:

opentrade trade routers

Response format:

{
  "ok": true,
  "data": [
    {
      "api": "v2",
      "created_at": "2026-03-10 01:15:42",
      "is_active": true,
      "name": "6551dex test",
      "quota_reward": 0,
      "trader": "6551dex",
      "updated_at": "2026-03-10 01:15:42"
    },
    {
      "api": "v1",
      "created_at": "2026-03-03 21:24:34",
      "is_active": true,
      "name": "okx test",
      "quota_reward": 0,
      "trader": "okx",
      "updated_at": "2026-03-03 21:24:34"
    }
  ]
}

Usage:

Extract trader and api from the response
MANDATORY: ALL subsequent opentrade commands in this session MUST include --trader <trader> and --api <api> flags
Example: opentrade swap quote --from 0x... --to 0x... --amount 100 --chain ethereum --trader okx --api v1
Default fallback: If the API returns no data or is empty, use --trader okx --api v1

Skill Routing

For user-specific holdings, positions, orders, or trade history → use opentrade-cex first; this DEX swap skill is only for quote/approve/swap execution.
For token search → use opentrade-token
For market prices → use opentrade-market
For transaction broadcasting → use opentrade-gateway
For wallet balances / portfolio → use opentrade-portfolio

Quickstart

EVM Swap (quote → approve → swap)

# 1. Quote — sell 100 USDC for OKB on XLayer
opentrade swap quote \
  --from 0x74b7f16337b8972027f6196a17a631ac6de26d22 \
  --to 0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee \
  --amount 100000000 \
  --chain xlayer
# → Expected: X.XX OKB, gas fee, price impact

# 2. Approve — ERC-20 tokens need approval before swap (skip for native OKB)
opentrade swap approve \
  --token 0x74b7f16337b8972027f6196a17a631ac6de26d22 \
  --amount 100000000 \
  --chain xlayer
# → Returns approval calldata: sign and broadcast via opentrade-gateway

# 3. Swap
opentrade swap swap \
  --from 0x74b7f16337b8972027f6196a17a631ac6de26d22 \
  --to 0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee \
  --amount 100000000 \
  --chain xlayer \
  --wallet 0xYourWallet \
  --slippage 1
# → Returns tx data: sign and broadcast via opentrade-gateway

Solana Swap

opentrade swap swap \
  --from 11111111111111111111111111111111 \
  --to DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 \
  --amount 1000000000 \
  --chain solana \
  --wallet YourSolanaWallet \
  --slippage 1
# → Returns tx data: sign and broadcast via opentrade-gateway

Chain Name Support

The CLI accepts human-readable chain names and resolves them automatically.

Chain	Name	chainIndex
XLayer	`xlayer`	`196`
Solana	`solana`	`501`
Ethereum	`ethereum`	`1`
Base	`base`	`8453`
BSC	`bsc`	`56`
Arbitrum	`arbitrum`	`42161`

Native Token Addresses

CRITICAL: Each chain has a specific native token address. Using the wrong address will cause swap transactions to fail.

Chain	Native Token Address
EVM (Ethereum, BSC, Polygon, Arbitrum, Base, etc.)	`0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee`
Solana	`11111111111111111111111111111111`
Sui	`0x2::sui::SUI`
Tron	`T9yD14Nj9j7xAB4dbGeiX9h8unkKHxuWwb`
Ton	`EQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAM9c`

WARNING — Solana native SOL: The correct address is 11111111111111111111111111111111 (Solana system program). Do NOT use So11111111111111111111111111111111111111112 (wSOL SPL token) — it is a different token and will cause swap failures.

Command Index

#	Command	Description
1	`opentrade swap chains`	Get supported chains for DEX aggregator

4	`opentrade swap quote --from ... --to ... --amount ... --chain ...`	Get swap quote (read-only price estimate)
5	`opentrade swap swap --from ... --to ... --amount ... --chain ... --wallet ...`	Get swap transaction data

Cross-Skill Workflows

This skill is the execution endpoint of most user trading flows. It almost always needs input from other skills first.

Workflow A: Full Swap by Token Name (most common)

User: "Swap 1 SOL for BONK on Solana"

1. opentrade-token    opentrade token search BONK --chains solana               → get BONK tokenContractAddress
       ↓ tokenContractAddress
2. opentrade-dex-swap opentrade swap quote \
                      --from 11111111111111111111111111111111 \
                      --to <BONK_address> --amount 1000000000 --chain solana → get quote
       ↓ user confirms
3. opentrade-dex-swap opentrade swap swap \
                      --from 11111111111111111111111111111111 \
                      --to <BONK_address> --amount 1000000000 --chain solana \
                      --wallet <addr>                                        → get swap calldata
4. User signs the transaction
5. opentrade-gateway  opentrade gateway broadcast --signed-tx <tx> --address <addr> --chain solana

Data handoff:

tokenContractAddress from step 1 → --to in steps 2-3
SOL native address = 11111111111111111111111111111111 → --from. Do NOT use wSOL address.
Amount 1 SOL = 1000000000 (9 decimals) → --amount param

Workflow B: EVM Swap with Approval

User: "Swap 100 USDC for OKB on XLayer"

1. opentrade-token    opentrade token search USDC --chains xlayer               → get USDC address
2. opentrade-dex-swap opentrade swap quote --from <USDC> --to 0xeeee...eeee --amount 100000000 --chain xlayer
       ↓ check isHoneyPot, taxRate, priceImpactPercent
3. opentrade-dex-swap opentrade swap approve --token <USDC> --amount 100000000 --chain xlayer
4. User signs the approval transaction
5. opentrade-gateway  opentrade gateway broadcast --signed-tx <tx> --address <addr> --chain xlayer
6. opentrade-dex-swap opentrade swap swap --from <USDC> --to 0xeeee...eeee --amount 100000000 --chain xlayer --wallet <addr>
7. User signs the swap transaction
8. opentrade-gateway  opentrade gateway broadcast --signed-tx <tx> --address <addr> --chain xlayer

Key: EVM tokens (not native OKB) require an approve step. Skip it if user is selling native tokens.

Workflow C: Compare Quote Then Execute

1. opentrade swap quote --from ... --to ... --amount ... --chain ...  → get quote with route info
2. Display to user: expected output, gas, price impact, route
3. If price impact > 5% → warn user
4. If isHoneyPot = true → block trade, warn user
5. User confirms → proceed to approve (if EVM) → swap

Swap Flow

EVM Chains (XLayer, Ethereum, BSC, Base, etc.)

1. opentrade swap quote ...              → Get price and route
2. opentrade swap approve ...            → Get approval calldata (if needed)
3. User signs the approval transaction
4. opentrade gateway broadcast ...       → Broadcast approval tx
5. opentrade swap swap ...               → Get swap calldata
6. User signs the swap transaction
7. opentrade gateway broadcast ...       → Broadcast swap tx

Solana

1. opentrade swap quote ...              → Get price and route
2. opentrade swap swap ...               → Get swap calldata
3. User signs the transaction
4. opentrade gateway broadcast ...       → Broadcast tx

Operation Flow

Step 1: Identify Intent

View a quote → opentrade swap quote
Execute a swap → full swap flow (quote → approve → swap)
List available DEXes → opentrade swap liquidity
Approve a token → opentrade swap approve

Step 2: Collect Parameters

Missing chain → recommend XLayer (--chain xlayer, low gas, fast confirmation) as the default, then ask which chain the user prefers
Missing token addresses → use opentrade-token opentrade token search to resolve name → address
Missing amount → ask user, remind to convert to minimal units
Missing slippage → suggest 1% default, 3-5% for volatile tokens
Missing wallet address → ask user

Step 3: Execute

Quote phase: call opentrade swap quote, display estimated results
- Expected output, gas estimate, price impact, routing path
- Check isHoneyPot and taxRate — surface safety info to users
Confirmation phase: wait for user approval before proceeding
Approval phase (EVM only): check/execute approve if selling non-native token
Execution phase: call opentrade swap swap, return tx data for signing

Step 4: Suggest Next Steps

After displaying results, suggest 2-3 relevant follow-up actions:

Just completed	Suggest
`swap quote` (not yet confirmed)	1. View price chart before deciding → `opentrade-market` 2. Proceed with swap → continue approve + swap (this skill)
Swap executed successfully	1. Check price of the token just received → `opentrade-market` 2. Swap another token → new swap flow (this skill)
`swap liquidity`	1. Get a swap quote → `opentrade swap quote` (this skill)

Present conversationally, e.g.: "Swap complete! Would you like to check your updated balance?" — never expose skill names or endpoint paths to the user.

# 3. Swap
opentrade swap swap --from 0x74b7f16337b8972027f6196a17a631ac6de26d22 --to 0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee --amount 100000000 --chain xlayer --wallet 0xYourWallet --slippage 1
# → Returns tx data → user signs → broadcast

User says: "What DEXes are available on XLayer?"

opentrade swap liquidity --chain xlayer
# → Display: CurveNG, XLayer DEX, ... (DEX sources on XLayer)

Edge Cases

High slippage (>5%): warn user, suggest splitting the trade or adjusting slippage
Large price impact (>10%): strongly warn, suggest reducing amount
Honeypot token: isHoneyPot = true — block trade and warn user
Tax token: taxRate non-zero — display to user (e.g. 5% buy tax)
Insufficient balance: check balance first, show current balance, suggest adjusting amount
exactOut not supported: only Ethereum/Base/BSC/Arbitrum — prompt user to use exactIn
Solana native SOL address: Must use 11111111111111111111111111111111 (system program), NOT So11111111111111111111111111111111111111112 (wSOL)
Network error: retry once, then prompt user to try again later
Region restriction (error code 50125 or 80001): do NOT show the raw error code to the user. Instead, display a friendly message: ⚠️ Service is not available in your region. Please switch to a supported region and try again.

Amount Display Rules

Input/output amounts in UI units (1.5 ETH, 3,200 USDC)
Internal CLI params use minimal units (1 USDC = "1000000", 1 ETH = "1000000000000000000")
Gas fees in USD
minReceiveAmount in both UI units and USD
Price impact as percentage

Global Notes

Amounts must be in minimal units (wei/lamports)
exactOut only on Ethereum(1)/Base(8453)/BSC(56)/Arbitrum(42161)
Check isHoneyPot and taxRate — surface safety info to users
EVM contract addresses must be all lowercase
The CLI resolves chain names automatically (e.g., ethereum → 1, solana → 501)
The CLI handles authentication internally via environment variables — see Prerequisites step 4 for default values
