Your Progress
0 / 5 completed🚀 Deploying Your Token
Deploying a token is permanent on Ethereum mainnet. Plan carefully—you cannot change core parameters after deployment.
⚠️
Important Considerations
- •Gas Costs: Deployment costs 1-2M gas (~$50-100 at 50 gwei)
- •Immutability: Code and parameters are permanent
- •Security: Bugs can lead to loss of funds
