The Arena has many talented gladiators - with a rare few bringing amazing free tools and information for us all. Below is a list of the best:
The Arena Accelerator
The Arena Accelerator was created by @Requn96 (Marcus) to help everyone grow their personal brand, engage with their audience, and monetize their efforts. Marcus is seriously one of the nicest and helpful gladiators in the Arena. At the very least give him a follow and check out @TheArenaTalks, another valuable source of help and information.
The Arena Docs
The Arena Docs was created by @Tedz_Nftz (Tedz) to be a quick and easy guide to help new users navigate and learn the Arena. Known as The Unofficial Wiki for The Arena, there is plenty of information here and should be one of your first stops if you are relatively new to The Arena.
Cast3
Cast3 was created by @prettyjson (Jason) with the idea being to promote Arena posts and earn rewards. Any Arena post can be selected to boost, with likes/ reposts/ quotes/ comments all options available to be used to promote and earn.
Arena Staking Dashboard
The Arena Staking Dashboard was created by @0x_Ali3N RebornAli3N and is a live window into $arena staking on the Arena, with enough numbers, graphs and stats to please everyone.
The Arena Dashboard
The Arena Dashboard was created by @PolyPup1 and is a snapshot of the current state of play of $arena. There is also an excellent Snapshot Holders function which allows you to get your current ticket holders list and airdrop tokens to them.
