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:
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:
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, andAntimevWithNonceroutes - 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.
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.
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).
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).
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.
