# gala_launchpad_sell

Execute token sale with slippage protection. WORKFLOW: 1. calculateSellAmount() -> Get expected output (result.amount and result.reverseBondingCurveFee) 2. sell() -> Execute trade with expectedAmount (and optionally maxAcceptableReverseBondingCurveFee) 3. fetchTrades() -> Verify trade completed - result.amount -> expectedAmount - result.reverseBondingCurveFee -> maxAcceptableReverseBondingCurveFee (optional: when omitted the SDK quotes the fee itself and allows it plus 1% slippage) RETURNS: Transaction details including input/output amounts and transaction ID.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `type` | string | yes | Trade type (must match what you used in calculateSellAmount): - 'native': Receiving GALA amount - 'exact': Selling exact token amount. |
| `amount` | string | yes | Amount to sell/receive. |
| `tokenName` | string | yes | Token name. |
| `privateKey` | string | no | Optional private key override for this operation (format: "0x" + 64 hex characters). If provided, uses this wallet instead of the default MCP server wallet. |
| `expectedAmount` | string | yes | Expected GALA output amount from calculateSellAmount (REQUIRED). CRITICAL: This is the 'amount' field from calculateSellAmount result, NOT your input amount. |
| `slippageToleranceFactor` | number | yes | Decimal format (0.05 = 5% slippage). |
| `maxAcceptableReverseBondingCurveFee` | string | no | OPTIONAL: Base reverse bonding curve fee from calculateSellAmount (GALA), result.reverseBondingCurveFee. The ceiling sent is this fee plus maxAcceptableReverseB |
| `maxAcceptableReverseBondingCurveFeeSlippageFactor` | number | no | Optional slippage tolerance for reverse bonding curve fee (decimal, e.g., 0.01 for 1%). Defaults to 0.01 (1%) if not provided. Applied to maxAcceptableReverseBo |

## Why gala_launchpad_sell is rated High

gala_launchpad_sell triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

## Use case

AI agents invoke gala_launchpad_sell to trigger actions in Gala. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Gala:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "gala_launchpad_sell": {
      "limits": [
        {
          "counter": "gala_launchpad_sell_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
