Learn-skills.dev opentrade-dex-swap

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. Do NOT use for general programming questions about swap code, or for analytical questions about historical swap volume.

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.

  1. 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

  2. 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.
  3. 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
    
  4. 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

Get your API token at: https://6551.io/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 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

Native Token Addresses

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

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 completedSuggest
swap quote
(not yet confirmed)
1. View price chart before deciding →
opentrade-market
2. Proceed with swap → continue approve + swap (this skill)
Swap executed successfully1. 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.

Input / Output Examples

User says: "Swap 100 USDC for OKB on XLayer"

# 1. Quote
opentrade swap quote --from 0x74b7f16337b8972027f6196a17a631ac6de26d22 --to 0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee --amount 100000000 --chain xlayer
# → 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
