starport VS relayer

Starport: Github • Telegram • Discord

One of the great things about the Cosmos Ecosystem is the sheer amount of modules available for integration. Moreover, tools like Starport make it super simple to create a new chain. We've also benefited immensely from the work of the Confio team on the CosmWasm module. Thanks to all these community efforts, Juno is fully working today.

Starport - Cosmos: The Internet of Blockchains

Hello, I’m trying to build a blockchain using startport, I have watched this video https://youtu.be/DhciTJHxvAY but I haven’t understood how the "system works" since in the docs https://github.com/tendermint/starport/tree/develop/docs it’s not discussed the "network create chain" command, and I thought the new chain already started after "starport serve"

Starport would be the way https://github.com/tendermint/starport

(3) GitHub - cosmos/relayer: An IBC relayer for ibc-go. https://github.com/cosmos/relayer.

“Hi mate - I've mostly been testing with Hermes (https://hermes.informal.systems/). I've also had a play with Cosmos's own relayer (https://github.com/cosmos/relayer). The Cosmos Relayer looks promising in future, but Hermes is well established and I believe is currently the most used. We'll most likely use Hermes for our Gravity relayer.” - Codegnosis, Unification Foundation Senior Dev/Architect and admin of its official Discord server commented on AUG15 at 4:19am.

another question is related to gas fee for setting up Relayer, I haven’t how the fee works here https://github.com/cosmos/relayer it’s written that both accounts can pay fees to send tokens from one address to another, since it’s a cross-chain transfer whats the gass token that is used to pay the fees? Atom?
