Fantom Genesis Files Repository

Here you can find list of genesis files needed to start a new Fantom network node. If you are not sure what these files are used for, please continue to the Fantom Foundation website to get information about the Sonic, Opera, and running a Fantom Network node in general.

Sonic Builders Test Net

You need one of these to start Fantom Sonic node on the Sonic Builders Test Net.

The default Sonic mode of operation is --mode rpc. This mode builds up the history and allows you to interact with the state and contracts. You can actually use a validator genesis to prime a node to a smaller pruned DB and still run this mode. Your history calls will be limited to the epoch of the genesis used though.

Use --mode validator flag for genesis expansion and also for the Sonic node startup to enable live pruning. A node in the validator mode will not allow you to execute most of the RPC calls.

You may want to add these Builders Test Net nodes as trusted static sources to your config.toml file to speed up your synchronisation with the small test network.
