I. Authentication

⚠️ SECURITY: All credentials below are 🔴 Secret-level. They MUST be loaded from environment variables via process.env.*, NEVER hardcoded in source, logged, or transmitted in chat. See §XVI for the complete credential registry and agent rules.

OKX (HMAC-SHA256)

text

Headers: OK-ACCESS-KEY, OK-ACCESS-SIGN, OK-ACCESS-PASSPHRASE, OK-ACCESS-TIMESTAMP
SIGN = Base64(HMAC-SHA256(timestamp+method+requestPath+body, SECRET))

II. Chain ID Mapping

Chain	OKX	Binance	K-Line Platform	Native Token Address
Ethereum	1	1	eth	0xeeee...eeee
BSC	56	56	bsc	0xeeee...eeee
Solana	501	CT_501	solana	11111111111111111111111111111111
Base	8453	8453	base	0xeeee...eeee
Arbitrum	42161	—	—	0xeeee...eeee
Polygon	137	—	—	0xeeee...eeee

CRITICAL: Solana native SOL uses 11111111111111111111111111111111. Do NOT use wSOL (So111...112) — causes custom program error: 0xb. Exception: candles and trades endpoints require the wSOL address. Binance Solana chainId is CT_501, not 501.

Wrapped Native: BSC 0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c | ETH 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 | Base 0x4200000000000000000000000000000000000006

V. Domain 3 — Security Audit & Safety Scoring

Binance Token Audit

POST bapi/.../security/token/audit Body: { "binanceChainId": "56|8453|CT_501|1", "contractAddress": "...", "requestId": "uuid" } Results valid ONLY when hasResult=true AND isSupported=true riskLevel: 0-1=LOW 2-3=MEDIUM 4=HIGH 5=BLOCK TRADE

Production 10-Point Safety Scoring

#	Check	Safe Threshold
1	LP Lock Rate	≥80%
2	Top10 Holder Concentration	≤45%
3	Liquidity (USD)	≥$15,000
4	Market Cap (USD)	≥$20,000
5	Holder Count	≥150
6	Insider Holding %	≤10%
7	Sniper Holding %	≤8%
8	24h Transaction Count	≥80
9	Dev Rug-Pull History	= 0
10	Dev Coins Launched	≤5

Score = passedCount / totalChecks × 100. Pass requires: all checks passed AND totalChecks ≥ 3.

Honeypot Detection (Round-Trip Simulation)

1. Simulate BUY: WNATIVE → Token (record amountOut)
2. Simulate SELL: Token → WNATIVE (use amountOut as input)
3. Recovery ratio = sellOut / originalAmount × 100
4. <50% = honeypot (85% confidence) | =0 = honeypot (90%) | 50-80% = suspicious | >80% = normal

Contract Risk Flags

isHoneypot → BLOCK | hasMintMethod → HIGH risk | isLpNotLocked → Rug risk | hasNotRenounced → MEDIUM | isInBlacklist → MEDIUM

---

VI. Domain 4 — Wallet & Portfolio

API	Method	Path
OKX Total Value	GET	/api/v6/dex/balance/total-value-by-address?address=&chains=
OKX All Balances	GET	/api/v6/dex/balance/all-token-balances-by-address?address=&chains=
OKX Token Balance	POST	/api/v6/dex/balance/token-balances-by-address
Binance Positions	GET	bapi/.../address/pnl/active-position-list?address=&chainId=&offset=0

Note: OKX excludeRiskToken is Boolean for total-value but String("0"/"1") for token-balances. Native token: tokenContractAddress = "" (empty string).

---

VII. Domain 5 — DEX Swap Execution

OKX Aggregator (all GET)

Endpoint	Purpose
/api/v6/dex/aggregator/quote?chainIndex=&fromTokenAddress=&toTokenAddress=&amount=	Get quote
/api/v6/dex/aggregator/approve-transaction?chainIndex=&tokenContractAddress=&approveAmount=	ERC20 approval
/api/v6/dex/aggregator/swap?chainIndex=&...&slippagePercent=1&userWalletAddress=	Swap calldata
/api/v6/dex/aggregator/swap-instruction?chainIndex=501&...	Solana deserialized instructions

Amount must be in minimal units (wei/lamports). Default slippage: 1%.

Smart Router (V2/V3 Auto-Selection)

Query all routes in parallel → pick highest amountOut:

1. V2 Router getAmountsOut(amountIn, [tokenIn, tokenOut])
2. V3 Quoter quoteExactInputSingle across ALL fee tiers (100, 500, 3000, 10000)
3. Sort by amountOut descending → select best

V2 Routers: BSC 0x10ED43C718714eb63d5aA57B78B54704E256024E | ETH 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D | Base 0x4752ba5DBc23f44D87826276BF6Fd6b1C372aD24 V3 Routers: ETH 0xE592427A0AEce92De3Edee1F18E0157C05861564 | Base 0x2626664c2603336E57B271c5C0b26F421741e481 | BSC 0x13f4EA83D0bd40E75C8222255bc855a974568Dd4 V3 Fees: 100 (0.01% stables), 500 (0.05%), 3000 (0.3% most pairs), 10000 (1% exotic)

Turbo Direct Pool (~15k-30k gas savings)

Bypass router, call pool contracts directly:

• V2: transfer token to pair → pair.swap(amount0Out, amount1Out, to, 0x)
• V3: fallback to SwapRouter exactInputSingle (EOA can't call pool.swap callback)
• V2 formula: amountOut = amountIn×997×reserveOut / (reserveIn×1000 + amountIn×997)

Solana Auto-Dispatch

isPumpToken? → Pump.fun direct buy/sell : Jupiter aggregator

Safety Patterns

• Approve ONLY required amount — never maxUint256
• Quote failure → BLOCK trade (prevents sandwich attacks)
• Slippage: amountOutMin = expectedOut × (10000 - slippageBps) / 10000

RPC Health-Aware Failover

Per-chain node health map: { url, healthy, latencyMs, failCount }

1. Select: healthy nodes → sort by latency → return lowest
2. All unhealthy: return node with fewest failures (graceful degradation)
3. On success: reset failCount, update latencyMs
4. On failure: failCount++; ≥3 consecutive → mark unhealthy
5. Background probe every 30s: eth_blockNumber to all nodes, 5s timeout

---

Risk Gates

Condition	Action

Error Handling

Source	Code	Meaning	Action
OKX	50011	Rate limited	Exponential backoff + jitter
OKX	81104	Chain unsupported	Check /supported/chain
OKX	81451	Node failed	Check gas/nonce/revert
Binance Spot	-1021	Timestamp drift	Sync clock
Binance Spot	-2010	Order rejected	Check balance/permissions
Gate.io	401	Auth failed	Verify KEY + SIGN
Gate.io	429	Rate limited	Check X-Gate-RateLimit headers
Bitget	401	Auth failed	Verify KEY + SIGN + timestamp (±10s)
Solana	0xb	Wrong address	Use native SOL address
EVM	nonce too low	Already mined	Fetch latest nonce

Timeout: All APIs 10s timeout. On broadcast/order timeout → check status before retry (prevent double-spend).

---

Core Rules

Security: Never output raw keys. Approve only required amounts. Mainnet ops require CONFIRM. Quote failure = block. See §XVI–§XVII for full credential handling rules. Units: APIs use minimal units (wei/lamports); display uses UI units. amount_min = amount_ui × 10^decimal. Formats: Gate.io uses underscore pairs "BTC_USDT"; Bitget uses no separator "BTCUSDT". Fallback: OKX search ↔ Binance search, OKX candles ↔ Sintral K-line, OKX balance ↔ Binance positions. CEX failure → suggest alternative exchange. RPC: Auto-failover via health manager. 30s probe, 5s timeout, 3 consecutive failures = unhealthy. Output: Concise decision summaries → risk flags first → blocked trades get reason + alternatives → disclaimer at end.

Defaults: slippage=1% | ranking pageSize=20-50 | signals=active only | meme default=rankType=20 (migration) | PnL=30d | V3 fee=3000 | tx deadline=300s

XVI. Credential & Environment Variable Registry

This skill requires credentials for 5 providers. Below is the complete registry of all environment variables, their purpose, and security classification.

RPC_SOL	Solana RPC	Chain interaction	🟡 Sensitive
DEPLOYER_PRIVATE_KEY	EVM tx signing	On-chain trade execution	🔴 Critical
SOL_PRIVATE_KEY	Solana tx signing	On-chain trade execution	🔴 Critical
VAULT_TIMEOUT_MS	Vault	Auto-lock duration	⚪ Config
ENABLE_TESTNET	Routing	Route through testnets	⚪ Config

Sensitivity Levels

text

⚪ Config:     Safe to commit to .env.example as placeholder values
🟡 Sensitive:  Must be in .env (gitignored), contains API keys or RPC endpoints with keys
🔴 Secret:     Must NEVER appear in logs, code, or git history
🔴 Critical:   Private keys — highest security; compromise = total fund loss

Agent Behavior: When to Request Credentials

text

Rule 1: NEVER invent, generate, or hardcode real API keys or secrets.
        Use placeholder values in .env.example only.
Rule 2: When scaffolding, create .env.example with descriptive placeholders:
        OKX_API_KEY=your-okx-api-key
        OKX_SECRET_KEY=your-okx-secret-key
        DEPLOYER_PRIVATE_KEY=0x_DO_NOT_COMMIT_REAL_KEY
Rule 3: Add .env to .gitignore BEFORE any .env file is created.
Rule 4: When a feature needs a credential not yet configured:
        → Tell the user which variable is needed and which provider dashboard to get it from
        → Provide the provider's API key management URL:
          - OKX: https://www.okx.com/account/my-api
          - Binance: https://www.binance.com/en/my/settings/api-management
          - Gate.io: https://www.gate.io/myaccount/apikeys
          - Bitget: https://www.bitget.com/account/newapi
          - Alchemy (RPC): https://dashboard.alchemy.com
        → Ask the user to set it in .env
        → NEVER ask the user to paste secrets into chat
Rule 5: For DEPLOYER_PRIVATE_KEY / SOL_PRIVATE_KEY:
        → Recommend generating locally (cast wallet new, solana-keygen new)
        → For mainnet: use hardware wallet or the project Vault system
        → NEVER use a funded mainnet key in .env on a dev machine
Rule 6: When implementing auth signing functions:
        → Load secrets with process.env.* at module init
        → Validate presence at startup: if (!key) throw new Error('Missing OKX_API_KEY')
        → NEVER pass secrets as function parameters through the call stack
Rule 7: Agent Scope Limits (Infrastructure):
        → The agent runs purely as a trading helper. Infrastructure secrets 
          (e.g., DATABASE_URL, REDIS_URL, JWT_SECRET) are EXPLICITLY OUT OF SCOPE.
        → NEVER attempt to read, request, or persist data directly using backend services.
        → All state must be passed through safe API layers, never via direct DB connections.

XVII. Security: Agent Rules for Sensitive Key Handling

Mandatory rules for any AI agent following this skill when handling API keys, private keys, and credential material during development, testing, and deployment.

Agent MUST Rules (Non-Negotiable)

text

1. NEVER echo, log, print, or return API keys/secrets to stdout, stderr, or chat.
   Masking rule: key.slice(0,4) + '****' + key.slice(-4)
2. NEVER include real secrets in code, comments, commit messages, or artifacts.
3. NEVER store secrets in source-controlled files.
   Only .env (which MUST be in .gitignore) may contain real credentials.
4. NEVER transmit secrets over unencrypted channels or embed in URLs.
5. When writing HMAC signing utilities:
   → Secret key MUST come from process.env exclusively
   → The signing function MUST NOT log the computed signature in production
   → Timestamp synchronization: use server time diff calibration
6. When writing trade execution code:
   → Private keys MUST be decrypted from Vault at execution time only
   → Zero-fill key Buffer after use: keyBuffer.fill(0)
   → NEVER cache decrypted private keys in global scope
7. When writing Docker/CI configs:
   → Use secrets managers (Docker secrets, GitHub Actions secrets)
   → NEVER bake API keys into Docker images or CI YAML
8. When implementing CEX API clients:
   → Use IP whitelisting where the exchange supports it (all 4 do)
   → Enable TRADE-ONLY permissions — WITHDRAWAL PERMISSION MUST BE DISABLED on all keys
   → Implement separate key pairs for spot vs futures (Gate.io requirement)
   → Verify no withdrawal permission is enabled before any integration test
9. Principle of Least Privilege enforcement:
   → OKX:     Read + Trade. Withdrawal = OFF. IP whitelist = REQUIRED.
   → Binance:  Read + Trade. Withdrawal = OFF. Margin = OFF unless explicitly needed.
   → Gate.io:  Spot trade only. Futures = SEPARATE key. Withdrawal = OFF.
   → Bitget:   Read + Trade. Withdrawal = OFF. IP whitelist recommended.
   → EVM key:  Dedicated wallet, minimal balance, never a primary wallet.
   → SOL key:  Dedicated wallet, minimal balance, never a primary wallet.
10. Testnet-first mandate:
    → Set ENABLE_TESTNET=true and test ALL workflows on testnets BEFORE mainnet.
    → Binance testnet: testnet.binance.vision
    → Only after successful testnet validation may the agent proceed to mainnet.

Exchange-Specific Security Notes

Exchange	Key Rotation	IP Whitelist	Permission Granularity	Notes
OKX	90-day recommended	✅ Required for trade	Read / Trade / Withdraw	Passphrase adds extra layer
Binance	No expiry, manual	✅ Strongly recommended	Read / Trade / Withdraw / Margin	Enable HMAC-only (no Ed25519) for compatibility
Gate.io	No expiry, manual	✅ Available	Spot / Futures / Withdrawal (separate)	Spot and Futures need SEPARATE key pairs
Bitget	No expiry, manual	✅ Available	Read / Trade / Withdraw	Passphrase required; ±10s timestamp tolerance

.env.example Template

The agent MUST generate this file when scaffolding a project using this skill:

bash

# === OKX DEX Aggregator (https://www.okx.com/account/my-api) ===
OKX_API_KEY=your-okx-api-key
OKX_SECRET_KEY=your-okx-secret-key
OKX_PASSPHRASE=your-okx-passphrase

# === Binance Spot (https://www.binance.com/en/my/settings/api-management) ===
BINANCE_API_KEY=your-binance-api-key
BINANCE_SECRET_KEY=your-binance-secret-key

# === Gate.io Spot (https://www.gate.io/myaccount/apikeys) ===
# NOTE: Spot and Futures require SEPARATE key pairs
GATE_API_KEY=your-gate-spot-api-key
GATE_SECRET_KEY=your-gate-spot-secret-key

# === Bitget Spot (https://www.bitget.com/account/newapi) ===
BITGET_API_KEY=your-bitget-api-key
BITGET_SECRET_KEY=your-bitget-secret-key
BITGET_PASSPHRASE=your-bitget-passphrase

# === Blockchain RPC (https://dashboard.alchemy.com) ===
RPC_ETH=https://eth-mainnet.g.alchemy.com/v2/YOUR_KEY
RPC_BSC=https://bsc-dataseed1.binance.org
RPC_BASE=https://base-mainnet.g.alchemy.com/v2/YOUR_KEY
RPC_ARB=https://arb-mainnet.g.alchemy.com/v2/YOUR_KEY
RPC_SOL=https://api.mainnet-beta.solana.com

# === On-Chain Signing (NEVER commit funded mainnet keys) ===
# Generate a fresh dedicated wallet: cast wallet new (EVM) | solana-keygen new (Solana)
# Use a SMALL-BALANCE ONLY wallet. NEVER use a primary/funded mainnet wallet here.
DEPLOYER_PRIVATE_KEY=
# ↑ Leave blank. Populate ONLY with a freshly generated, isolated dev/test wallet key.
SOL_PRIVATE_KEY=
# ↑ Leave blank. Base58 key — generate with: solana-keygen new --no-bip39-passphrase

# === Infrastructure ===
# NOTE: Trade_Tool backend services manage their own standalone configuration.
# Infrastructure secrets (DB, Redis, JWT) are completely isolated from this agent skill.
VAULT_TIMEOUT_MS=28800000
ENABLE_TESTNET=true

XVIII. Pre-Install Security Checklist

Before activating this skill with live credentials, verify every item below:

#	Check	Status
1	Testnet first — ENABLE_TESTNET=true tested successfully before mainnet	☐
2	Dedicated wallets — DEPLOYER_PRIVATE_KEY / SOL_PRIVATE_KEY are fresh wallets with minimal balance, not your primary wallet	☐
3	Withdrawal disabled — All CEX API keys (OKX / Binance / Gate / Bitget) have withdrawal permission explicitly OFF	☐
4	IP whitelist enabled — All exchange API keys locked to your server's IP address	☐
5	Trade-only scope — No Margin, Futures, or Cross-account permissions granted unless required	☐
6	Secrets in .env only — Credentials stored in .env (gitignored), never in source code or chat	☐
7	Vault for mainnet — Production keys stored in the project Vault system, not plain .env	☐
8	Provenance verified — Skill source confirmed at https://github.com/StanPoldark/Trade_Tool	☐
9	Metadata in sync — requiredEnv in YAML frontmatter matches §XVI table (verify: diff the name: fields in the YAML block against the §XVI Variable column, zero delta expected)	☐
10	Small balance test — First mainnet trade uses smallest viable amount to validate integration	☐

How to use: Copy this checklist into your project's SECURITY.md and confirm each item before going live. Skip any item only if that provider is not used in your deployment.
