OpenTrade DEX Aggregator CLI

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

Pre-flight Checks

Every time before running any opentrade command, always 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/openskills/main/skills/opentrade/install.sh | sh
```
If the install script fails, ask the user to install manually following the instructions at: https://github.com/6551Team/openskills
Check for updates: Read ~/.opentrade/last_check and compare it with the current timestamp:
```
cached_ts=$(cat ~/.opentrade/last_check 2>/dev/null || true)
now=$(date +%s)
```
- If cached_ts is non-empty and (now - cached_ts) < 43200 (12 hours), skip the update and proceed.
- Otherwise (file missing or older than 12 hours), run the installer to check for updates:
```
curl -sSL https://raw.githubusercontent.com/6551Team/openskills/main/skills/opentrade/install.sh | sh
```
  If a newer version is installed, tell the user and suggest updating their opentrade skills from https://github.com/6551Team/openskills 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/openskills/main/skills/opentrade/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.

OPEN_TOKEN=your_token_here

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:

{
  "data": [
    {
      "name": "okx test",
      "router": "okx",
      "version": "v1",
      "quota_reward": 0,
      "is_active": true,
      "created_at": "2026-03-03 21:24:34",
      "updated_at": "2026-03-03 21:24:34"
    }
  ],
  "success": true
}

Usage:

Extract router and version from the response
MANDATORY: ALL subsequent opentrade commands in this session MUST include --trader <router> and --api <version> 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 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.

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.

# → Expected output: 3.2 OKB, Gas fee: ~$0.001, Price impact: 0.05%

# 2. Approve (ERC-20 token needs approval)
opentrade swap approve --token 0x74b7f16337b8972027f6196a17a631ac6de26d22 --amount 100000000 --chain xlayer
# → Returns approval calldata → user signs → broadcast

# 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
