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.IO
HTTP

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

await fetch("https://api.chainworks.co/svm/buy/transaction", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    Authorization: CHAINWORKS_API_AUTH_TOKEN,
  },
  body: JSON.stringify({
    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.IO
HTTP

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)
});

await fetch("https://api.chainworks.co/svm/buy/transaction", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    Authorization: CHAINWORKS_API_AUTH_TOKEN,
  },
  body: JSON.stringify({
    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)

The routes that require a nonceAccount need a durable nonce account you own. Build one with Create Nonce Account Transaction, sign it, and submit it before using its address here.

`Public` (Default)

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

Socket.IO
HTTP

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

await fetch("https://api.chainworks.co/svm/buy/transaction", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    Authorization: CHAINWORKS_API_AUTH_TOKEN,
  },
  body: JSON.stringify({
    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.IO
HTTP

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

await fetch("https://api.chainworks.co/svm/buy/transaction", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    Authorization: CHAINWORKS_API_AUTH_TOKEN,
  },
  body: JSON.stringify({
    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.IO
HTTP

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

await fetch("https://api.chainworks.co/svm/buy/transaction", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    Authorization: CHAINWORKS_API_AUTH_TOKEN,
  },
  body: JSON.stringify({
    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.IO
HTTP

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

await fetch("https://api.chainworks.co/svm/buy/transaction", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    Authorization: CHAINWORKS_API_AUTH_TOKEN,
  },
  body: JSON.stringify({
    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.
