What is a network cost?#

A network cost is the CTN paid to process a transaction on Centurion. Computation is measured in Newtons, and the final cost depends on the Newtons used and the transaction's effective per-Newton price.

How it works#

Centurion uses a CIP-1559-style fee market with two main components:

  • Base fee: set per block according to network demand.
  • Priority fee: offered by the transaction to encourage timely inclusion.

Your wallet estimates a Newton limit and fee parameters before you sign. The limit is a safety cap on computation, not necessarily the amount that will be consumed. The transaction pays for actual execution up to that limit.

Simple CTN transfers normally use less computation than token approvals, swaps, v3 position changes, or complex smart-account batches. A failed transaction can still consume CTN because validators executed it and determined that it reverted.

Step-by-step#

  1. Switch your wallet to the intended Centurion network.
  2. Confirm that the account has native CTN, not only WCTN or other CRC-20 tokens.
  3. Start the action in CenturionDEX and review the wallet's estimated network cost.
  4. Check the destination contract and action before changing any advanced fee setting.
  5. Confirm the transaction and monitor its status through a current official Centurion explorer reached from official channels.
  6. If it remains pending, avoid repeatedly submitting identical transactions. Review nonce and replacement options in your wallet.

Native CTN versus WCTN#

WCTN is the CRC-20 representation used in pools. It can represent the same underlying value for wrapping purposes, but it cannot directly pay network costs. Keep some native CTN outside pool positions and token balances.

For example, a wallet may hold substantial WCTN but show “insufficient funds for network cost.” Unwrapping some WCTN to native CTN can solve the problem if the wallet and interface support the operation and enough CTN remains to submit it.

Common issues#

  • Estimate unavailable: the transaction may be expected to revert, the RPC connection may be stale, or token behavior may prevent simulation.
  • Cost rises before signing: base fees can change with demand.
  • Transaction failed but CTN decreased: consumed Newtons are charged even when state changes revert.
  • Pending for too long: the priority fee may be too low, or an earlier nonce may be blocking later transactions.
  • Testnet confusion: tCTN on Fornax or Centaurus has no mainnet value and cannot pay mainnet costs.

Stay safe#

A wallet fee prompt should never require your recovery phrase or private key. Do not use unverified “fee refill” sites. Verify the network, destination, and transaction data before signing.
