# SVM Transaction Fees & Send Routes

## Fee Parameters

Solana transactions support two types of fees:

### Priority Fees (`prioFees`)

Priority fees are paid to validators to prioritize your transaction in the block.

| Property | Type | Default | Description |
| --- | --- | --- | --- |
| `prioFees` | string | `"0"` | Amount in lamports to pay as priority fees |

**Example:**

```typescript
socket.emit("/svm/buy/transaction", {
  chain: "sol",
  token: "DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263",
  swapMode: "ExactIn",
  amountIn: "1000000000",
  wallet: "YourSolanaWalletPublicKey",
  prioFees: "100000", // 0.0001 SOL in lamports
});
```

**Notes:**

- Higher priority fees increase the likelihood of faster inclusion
- Paid regardless of transaction success or failure
- Optional - defaults to `"0"` if not specified

### Bribe Fees (`bribeFees`)

Bribe fees (also called MEV tips) are paid to MEV protection providers (e.g., Jito) to include your transaction in their bundles.

| Property | Type | Minimum | Description |
| --- | --- | --- | --- |
| `bribeFees` | string | `"1000000"` | Amount in lamports to pay as bribe/tip fees |

**Example:**

```typescript
socket.emit("/svm/buy/transaction", {
  chain: "sol",
  token: "DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263",
  swapMode: "ExactIn",
  amountIn: "1000000000",
  wallet: "YourSolanaWalletPublicKey",
  sendRoute: "Antimev",
  prioFees: "100000",
  bribeFees: "1000000", // 0.001 SOL (minimum)
});
```

**Notes:**

- Required for `PublicWithNonce`, `Antimev`, and `AntimevWithNonce` routes
- Minimum value is **1,000,000 lamports** (0.001 SOL)
- Provides MEV protection by routing through specialized providers
- Only paid if the transaction lands successfully (for revert-protected routes)

## Send Routes

The `sendRoute` parameter determines how your transaction is submitted to the network.

| Route | Default | Requires bribeFees | Requires nonceAccount | Description |
| --- | --- | --- | --- | --- |
| `Public` | ✅ Yes | ❌ No | ❌ No | Standard RPC submission only |
| `PublicWithNonce` | ❌ No | ✅ Yes | ✅ Yes | RPC + all MEV providers with tip |
| `Antimev` | ❌ No | ✅ Yes | ❌ No | Revert-protected MEV providers only |
| `AntimevWithNonce` | ❌ No | ✅ Yes | ✅ Yes | All MEV providers (revert-protected + others) |

### `Public` (Default)

The simplest route - sends your transaction through the standard public RPC only.

```typescript
socket.emit("/svm/buy/transaction", {
  chain: "sol",
  token: "DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263",
  swapMode: "ExactIn",
  amountIn: "1000000000",
  wallet: "YourSolanaWalletPublicKey",
  sendRoute: "Public",
  prioFees: "100000",
});
```

### `PublicWithNonce`

Sends through both public RPC and all MEV providers with a tip.

```typescript
socket.emit("/svm/buy/transaction", {
  chain: "sol",
  token: "DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263",
  swapMode: "ExactIn",
  amountIn: "1000000000",
  wallet: "YourSolanaWalletPublicKey",
  sendRoute: "PublicWithNonce",
  prioFees: "100000",
  bribeFees: "1000000",
  nonceAccount: "YourNonceAccountPublicKey",
});
```

### `Antimev`

Sends exclusively through revert-protected MEV providers (e.g., Jito bundles).

```typescript
socket.emit("/svm/buy/transaction", {
  chain: "sol",
  token: "DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263",
  swapMode: "ExactIn",
  amountIn: "1000000000",
  wallet: "YourSolanaWalletPublicKey",
  sendRoute: "Antimev",
  prioFees: "100000",
  bribeFees: "1000000",
});
```

**Best for:** High-value swaps where you want MEV protection and bribe fees only paid on success.

### `AntimevWithNonce`

Sends through all MEV providers (both revert-protected and non-revert-protected).

```typescript
socket.emit("/svm/buy/transaction", {
  chain: "sol",
  token: "DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263",
  swapMode: "ExactIn",
  amountIn: "1000000000",
  wallet: "YourSolanaWalletPublicKey",
  sendRoute: "AntimevWithNonce",
  prioFees: "100000",
  bribeFees: "1000000",
  nonceAccount: "YourNonceAccountPublicKey",
});
```

**Best for:** Maximizing MEV protection coverage across all providers.
