# Gas
DuckChain uses native **TON** as its gas token for transaction costs. TON on DuckChain has **18 decimals**, different from the 9-decimal precision on The Open Network to align with EVM-compatible chains' standards.
### **How to Get Gas Token**
* **Testnet**: Click to get Testnet gas.
* **Mainnet**: Bridge TON via the DuckChain official bridge or swap for TON as gas.
### **Gas Price**
The minimum allowable **Gas Price** for nodes on DuckChain is **0.1 Gwei(Testnet)/10 Gwei(Mainnet)**. Transactions with gas prices below this threshold will be automatically rejected.
