Gas Fees

Crypto Bomber operates purely on-chain, and due to this there is a necessity for gas fees to be constantly paid by the players using MATIC.
Gas fees are necessary to conduct operations on the Polygon Mainnet, and operating on-chain through the use of Chainlinks VRF technology ensures that all entropy-based gameplay scenarios such as minting NFTs or combat will always be provably fair.
Players are always required to hold an amount of MATIC in your MetaMask wallet to ensure the capability of conducting transactions and interacting with the Crypto Bomber smart contracts.
The gas fees usually cost around 0.03 MATIC depending on the transaction, however certain transactions such as claiming experience can be higher depending on the numerical data involved.

Fight Gas Cost

Combat gas fees are listed at 0.10 MATIC, however that is just a maximum amount that the player may pay. The true gas costs of fights are around 0.02 MATIC which can be seen in your MetaMask transactions.
Fighting prompts players for a set gas cost that is different from what is actually charged, the amount prompetd is the maximum fee to be paid (around 0.0.7 MATIC), but the actual cost is much lower as displayed in the picture below.

​
Due to the implementation of Early Withdraw Tax, it is recommended that new players hold a decent amount of MATIC to be used for gas fees.
The current recommended amount of MATIC is 1, give or take a few skill depending on the needs of the player.
This amount will sustain a player for a week's worth of fights, currently costing around 0.30 MATIC at most give or take a few MATIC to account for network traffic.
The remaining MATIC will be used for the various transactions a player might perform, such as claiming/staking CBOMBER, claiming experience, forging, etc.
