Goal

Participate smartly in the early ecosystem and help test the testnet infrastructure.

1. Community (Arc House) – Priority #1

This is the most important part right now. Points help you level up in the Architects program. The more active you are, the better.

Step What to do How to do it Frequency
1 Sign up for Arc House Go to community.arc.network → Sign up using Google or email Once
2 Complete your profile Click your avatar → Edit Profile and fill in all your details Once
3 Earn daily points (easy) Log in every day (+1 point) Daily
4 Read content Go to the Content section and read articles (2 points per article, max 5 a day) Daily
5 Watch videos Look for articles with videos and watch them (5 points per video, max 4 a day) Daily
6 Arc Architect Once you reach 500 points you can request the Architect badge on your profile Whenever possible
7 Engage more (recommended) Join the Discord (discord.gg/buildonarc), attend Office Hours and events Whenever possible

Becoming an Architect user will allow you to share ideas, be part of the builder and contributor team in the community, earn many more points, and subsequently join their official Discord server.

2. Testnet (After community engagement)

Once you’re already active in the community, proceed with these actions on the test network.

Add the Arc Testnet

Set up your wallet (like MetaMask or Rabby) with the following details:

  • Network Name: Arc Testnet
  • RPC: https://rpc.testnet.arc.network
  • Chain ID: 5042002
  • Symbol: USDC
  • Explorer: testnet.arcscan.app

Or you can visit: Logo de ChainlistChainlist and search for Arc Testnet, once found, click on Add to Metamask.

Get testnet tokens

  1. Go to faucet.circle.com
  2. Select Arc Testnet
  3. Request USDC, EURC and/or cirBTC (you can request every 2 hours)

Interact on the Testnet

  • Send USDC to another wallet
  • Deploy a simple contract
  • Use dApps running on the Arc Testnet like Synthra. Make a swap, provide liquidity, and use their perpetuals trading interface.
  • Signal 0xL: Interact with Signal 0xL (part of our 0x Leñador ecosystem). Use it to generate high-quality activity on the network and upload your signal.
  • Explore: Use the Arcscan explorer to view your transactions.

Stay consistent by following this routine divided into your two main focuses:

🏠 Community House

  • Daily: Log in and read 1-2 articles.
  • Weekly: Attend events or Office Hours on Discord.
  • Always: Maintain steady activity, don’t just cram it into one day.

⚙️ Testnet Network

  • Every 2-3 days: Request USDC from the official Circle faucet.
  • Every 2-3 days: Do 1 or 2 transactions (send USDC to another wallet or use dApps).

⚠️ Important Notes: Prioritize the community first, as that is where engagement is currently being measured the most. Participating in the testnet alone without being in the community carries less weight. This is simply a logical strategy to engage with the ecosystem early on. Be consistent but natural, don’t spam.
