Hey there
do you have any documentation to run Keep3r with Fantom?

Hi @Bolo,
We donāt as far as I know. I assume it is similar to running a Keep3r on Ethereum mainnet.
I found the following for Fantom:
Hey @bolo, if the network running on Fantom is equivalent to the one on Mainnet, it should not be too difficult to add support for it. Can you point us to the Keeper registry contract on the Fantom network, or to some documentation on Fantomās side?

I have found this.

According to ftmscan, the token has zero total supply and no holders, so it seems like itās still not operational. Iāve also reached out to Andre to see if he can provide more info.

I guess i should use a specific provider for Fantom ?
new ethers.providers.StaticJsonRpcProvider(url)

I think I found the correct token

If you connect your Autotask to a Fantom Relayer, you should get access to the network directly using a DefenderRelayProvider.
I've gone through the txs to that contract, and I'm not sure it's operational. The only txs I see are from the Deployer account for setting it up, and then a single failed bond operation (which I'm going to guess is yours). Did you get confirmation from the keep3r team or the fantom team that it's open to the public?

There are only 2 keepers who was added manually with function addKeeper.
I have tried on forum but without success.
FTM team on discord nobody really use it.
