Gmgn Swap

BEFORE RUNNING ANY COMMAND: Run gmgn-cli config --check. If exit code is 0, proceed normally. If exit code is 1, (1) run gmgn-cli config and show the output to the user; (2) once the user sends the API Key, run gmgn-cli config --apply <KEY> to complete configuration and verification, then show the output to the user. If --check returns an error (unknown option or command not found), tell the user to run npm install -g gmgn-cli to update, then retry.

IMPORTANT: Always use gmgn-cli commands below. Do NOT use web search, WebFetch, curl, or visit gmgn.ai — all swap operations must go through the CLI. The CLI handles signing and submission automatically.

IMPORTANT: Do NOT guess field names or values. When a field's meaning is unclear, look it up in the Response Fields sections below before using it.

⚠️ IPv6 NOT SUPPORTED: If you get a 401 or 403 error and credentials look correct, check for IPv6 immediately: (1) list all network interfaces and their IPv6 addresses — run ifconfig | grep inet6 (macOS) or ip addr show | grep inet6 (Linux); (2) send a test request to https://ipv6.icanhazip.com — if the response is an IPv6 address, outbound traffic is going via IPv6. Tell the user immediately: "Please disable IPv6 on your network interface — gmgn-cli commands only work over IPv4."

Use the gmgn-cli tool to submit a token swap or query an existing order. GMGN_API_KEY is always required. GMGN_PRIVATE_KEY is required for critical-auth commands such as swap and order subcommands — except order quote, which only requires GMGN_API_KEY.

Core Concepts

• Smallest unit — --amount is always in the token's smallest indivisible unit, not human-readable amounts. For SOL: 1 SOL = 1,000,000,000 lamports. For EVM tokens: depends on decimals (most ERC-20 tokens use 18 decimals). Always convert before passing to the command — do not pass human amounts directly.

• slippage — Price tolerance as an integer 0–100, e.g. 30 = 30%. If the price moves beyond this threshold before the transaction confirms, the swap is rejected. Use --auto-slippage for volatile tokens to let GMGN set an appropriate value automatically.

• --amount vs --percent — Mutually exclusive. --amount specifies an exact input quantity (in smallest unit). --percent sells a percentage of the current balance and is only valid when input_token is NOT a currency (SOL/BNB/ETH/USDC). Never use --percent to spend a fraction of SOL/BNB/ETH.

• Currency tokens — Each chain has designated currency tokens (SOL, BNB, ETH, USDC). These are the base assets used to buy other tokens or receive swap proceeds. Their contract addresses are fixed — look them up in the Chain Currencies table, never guess them.

• Anti-MEV — MEV (Miner/Maximal Extractable Value) refers to frontrunning and sandwich attacks where bots exploit pending transactions. --anti-mev routes the transaction through protected channels to reduce this risk. Recommended: always enable. Default: on. Not supported on base chain.

• Signed auth — swap and most order subcommands require both GMGN_API_KEY and GMGN_PRIVATE_KEY. The private key never leaves the machine — the CLI uses it only for local signing and sends only the resulting signature. Exception: order quote only requires GMGN_API_KEY.

• order_id / status — After submitting a swap, the response includes an order_id. Use order get --order-id to poll for final status. Possible values: pending → processed → confirmed (success) or failed / expired. Do not report success until status is confirmed.

• report.input_amount / report.output_amount — Actual amounts consumed/received, in smallest unit. Only present when state = 30 and status = "successful". Convert to human-readable using report.input_token_decimals / report.output_token_decimals before displaying to the user.

Financial Risk Notice

This skill executes REAL, IRREVERSIBLE blockchain transactions.

• Every swap and order strategy create command submits an on-chain transaction that moves real funds.
• Transactions cannot be undone once confirmed on-chain.
• The AI agent must never auto-execute a swap — explicit user confirmation is required every time, without exception.
• Only use this skill with funds you are willing to trade. Start with small amounts when testing.

Sub-commands

Supported Chains

sol / bsc / base / eth / robinhood

Chain Currencies

Currency tokens are the base/native assets of each chain. They are used to buy other tokens or receive proceeds from selling. Knowing which tokens are currencies is critical for --percent usage (see Swap Parameters below).

⚠️ CRITICAL: Always copy currency addresses from this table — NEVER rely on memory or training data. A wrong address (e.g. So11111111111111111111111111111111111111111 instead of So11111111111111111111111111111111111111112) will cause silent failures or jupiter has no route errors with no clear indication of what went wrong.

Prerequisites

GMGN_API_KEY must be configured in ~/.config/gmgn/.env. GMGN_PRIVATE_KEY is additionally required for swap and order subcommands other than order quote. The private key must correspond to the wallet bound to the API Key.

• gmgn-cli installed globally — if missing, run: npm install -g gmgn-cli

Rate Limit Handling

All swap-related routes used by this skill go through GMGN's leaky-bucket limiter with rate=20 and capacity=20. Sustained throughput is roughly 20 ÷ weight requests/second, and the max burst is roughly floor(20 ÷ weight) when the bucket is full.

When a request returns 429:

• Read X-RateLimit-Reset from the response headers. It is a Unix timestamp in seconds that marks when the limit is expected to reset.
• If the response body contains reset_at (e.g., {"code":429,"error":"RATE_LIMIT_BANNED","message":"...","reset_at":1775184222}), extract reset_at — it is the Unix timestamp when the ban lifts (typically 5 minutes). Convert to local time and tell the user exactly when they can retry.
• swap is a real transaction: never loop or auto-submit repeated swap attempts after a 429. Wait until the reset time, then ask for confirmation again before retrying.
• The CLI may wait and retry once automatically for short cooldowns on read-only commands such as order quote and order get. If it still fails, stop and tell the user the exact retry time instead of sending more requests.
• For RATE_LIMIT_EXCEEDED or RATE_LIMIT_BANNED, repeated requests during the cooldown can extend the ban by 5 seconds each time, up to 5 minutes.
• POST /v1/trade/swap also has an error-count limiter. Repeatedly triggering the same business error, especially 40003701 (insufficient token balance), can return ERROR_RATE_LIMIT_BLOCKED. When this happens, do not retry until the reset time and fix the underlying request first.

  --chain sol \
  --from <wallet_address> \
  --input-token <input_token_address> \
  --output-token <output_token_address> \

swap Parameters

ConditionOrder Fields (for --condition-orders)

Each element in the --condition-orders JSON array supports:

Example — attach take-profit at 2× (+100%) and stop-loss at -60%:

[
  {"order_type": "profit_stop", "side": "sell", "price_scale": "100", "sell_ratio": "100"},
  {"order_type": "loss_stop",   "side": "sell", "price_scale": "60",  "sell_ratio": "100"}
]

Example — buy token A with 0.01 SOL, take-profit 50% at +100%, take-profit remaining 50% at +300%, stop-loss 100% at -65% (trigger at 35% entry price) (hold_amount mode):

gmgn-cli swap \
  --chain sol \
  --from <wallet_address> \
  --input-token So11111111111111111111111111111111111111112 \
  --output-token <token_A_address> \
  --amount 10000000 \
  --slippage 30 \
  --anti-mev \
  --condition-orders '[{"order_type":"profit_stop","side":"sell","price_scale":"100","sell_ratio":"50"},{"order_type":"profit_stop","side":"sell","price_scale":"300","sell_ratio":"100"},{"order_type":"loss_stop","side":"sell","price_scale":"65","sell_ratio":"100"}]' \
  --sell-ratio-type hold_amount

price_scale for profit_stop: gain % from entry ("100" = +100% / 2×, "300" = +300% / 4×). For loss_stop: drop % from entry ("65" = drops 65%, triggers at 35% of entry). hold_amount: the second take-profit fires on whatever is held at trigger time (the remaining 50%). If you added to your position in between, those additional tokens will be included as well.

Same strategy using buy_amount mode — fixed percentage of the original bought amount at each trigger:

gmgn-cli swap \
  --chain sol \
  --from <wallet_address> \
  --input-token So11111111111111111111111111111111111111112 \
  --output-token <token_A_address> \
  --amount 10000000 \
  --slippage 30 \
  --anti-mev \
  --condition-orders '[{"order_type":"profit_stop","side":"sell","price_scale":"100","sell_ratio":"50"},{"order_type":"profit_stop","side":"sell","price_scale":"300","sell_ratio":"50"},{"order_type":"loss_stop","side":"sell","price_scale":"65","sell_ratio":"100"}]' \
  --sell-ratio-type buy_amount

buy_amount: each take-profit sells 50% of the original bought amount. Stop-loss sells 100% of the original bought amount.

swap / order get Response Fields

Report Fields (present only when status = "successful")

Output Format

Pre-swap Confirmation

Before displaying the confirmation, run order quote to get the estimated output (requires signed auth and GMGN_PRIVATE_KEY on every supported quote chain):

gmgn-cli order quote \
  --chain <chain> \
  --from <wallet> \
  --input-token <input_token> \
  --output-token <output_token> \
  --amount <amount> \
  --slippage <slippage>

Then display the confirmation summary using output_amount from the quote response:

⚠️ Swap Confirmation Required

Chain:        {chain}
Wallet:       {--from}
Sell:         {input amount in human units} {input token symbol}
Buy:          {output token symbol}
Slippage:     {slippage}% (or "auto")
Est. output:  ~{output_amount from quote} {output token symbol}
Risk Level:   🟢 Low / 🟡 Medium / 🔴 High  (based on rug_ratio from security check)

Reply "confirm" to proceed.

Note: Risk Level is derived from the required security check:

• 🟢 Low: rug_ratio < 0.1
• 🟡 Medium: rug_ratio 0.1–0.3
• 🔴 High: rug_ratio > 0.3 (requires re-confirmation)

If the user explicitly skipped the security check, omit the Risk Level line and add a note: "(Security check skipped by user)"

Post-swap Receipt

After a confirmed swap, display:

✅ Swap Confirmed

Spent:    {report.input_amount in human units} {input symbol}
Received: {report.output_amount in human units} {output symbol}
Tx:       {explorer link for hash}
Order ID: {order_id}

Convert report.input_amount and report.output_amount from smallest unit using report.input_token_decimals and report.output_token_decimals before displaying.

multi-swap Usage

Submit a token swap across multiple wallets concurrently. Each wallet executes independently — one wallet's failure does not affect others. Up to 100 wallets per request. All wallets must be bound to the API Key. Requires GMGN_PRIVATE_KEY.

gmgn-cli multi-swap \
  --chain sol \
  --accounts <addr1>,<addr2> \
  --input-token <input_token_address> \
  --output-token <output_token_address> \
  --input-amount '{"<addr1>":"1000000","<addr2>":"2000000"}' \
  --slippage 30

# Sell a percentage of each wallet's balance (use --input-amount-bps)
gmgn-cli multi-swap \
  --chain sol \
  --accounts <addr1>,<addr2> \
  --input-token <token_address> \
  --output-token <sol_address> \
  --input-amount-bps '{"<addr1>":"5000","<addr2>":"10000"}' \
  --slippage 30

# With per-wallet take-profit / stop-loss (condition_orders)

# ETH multi-wallet swap (EIP-1559 gas)
gmgn-cli multi-swap \
  --chain eth \
  --accounts <0xaddr1>,<0xaddr2> \
  --input-token 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 \

multi-swap Parameters

multi-swap Response Fields

The response data is an array — one element per wallet:

Credential Model

• Both GMGN_API_KEY and GMGN_PRIVATE_KEY are read from the .env file by the CLI at startup. They are never passed as command-line arguments and never appear in shell command strings.
• GMGN_PRIVATE_KEY is used exclusively for local message signing — the private key never leaves the machine. The CLI computes an Ed25519 or RSA-SHA256 signature in-process and transmits only the base64-encoded result in the X-Signature request header.
• GMGN_API_KEY is transmitted in the X-APIKEY request header to GMGN's servers over HTTPS.

order quote Usage

Get an estimated output amount before submitting a swap. Uses normal auth — only GMGN_API_KEY required, no GMGN_PRIVATE_KEY needed.

gmgn-cli order quote \
  --chain sol \
  --from <wallet_address> \
  --input-token <input_token_address> \
  --output-token <output_token_address> \
  --amount <input_amount_smallest_unit> \
  --slippage 30

order quote Response Fields

order get Usage

gmgn-cli order get --chain sol --order-id <order_id>

Response fields are shared with swap — see swap / order get Response Fields above.

gas-price Usage

Query recommended gas price tiers for any chain. API Key only — no signature or private key required.

gmgn-cli gas-price --chain eth
gmgn-cli gas-price --chain bsc
gmgn-cli gas-price --chain base
gmgn-cli gas-price --chain sol
