Arc Testnet Guide: Swaps, Liquidity, and Discord Engagement for Airdrop FarmingEnglish:

Arc is an open L1 blockchain — a platform for the crypto economy where developers from around the world can build applications for lending, trading, and cross-border payments directly on-chain. Network fees are stable and predictable, pegged to the US dollar. Transaction fees can be paid in stablecoins.

Getting tokens via a faucet

Start by visiting the Circle website using the link provided in the Syndicate app guide. Make sure to download the app if you haven’t installed it yet.

Get More with Syndicate App

If the site is unavailable in your region, use a VPN.
Open MetaMask and copy your wallet address.
In the first field, Arc Network is specified; below it is your wallet address.

Request tokens through the faucet and receive USDC.
To get EURC tokens, select Arc Network in the first field and bridge to Ethereum Sepolia.
Click EURC, set Ethereum Sepolia in the first field, and send.
You can use this faucet once every hour.

Visit the testnet website (the official link is in the Syndicate app as well) and find the DApps section:

Open MetaMask, copy your wallet address, and paste it into the search bar.
You will see your USDC balance, and in the Transactions section — the history of all your operations.

How to add the network to your wallet

Go to curve.finance (the Arc network is already connected).
To link MetaMask to the platform, click: Connect Wallet — Browser Wallet — Connect.

Open your wallet settings and edit the Arc Testnet parameters: in the RPC URL field, remove extra characters, leaving rpc.testnet.arc.network, and save.

Swaps

Swap one USDC for one WUSDC and confirm the transaction.
Set slippage to 5% to ensure the transaction goes through successfully.
To make the reverse swap, click Approve Spending and Confirm.

You can perform swaps as many times as you like.

Go back to the testnet website to the DApps section.

Start with Infinity Name. You will be redirected to the registration page — connect MetaMask, enter your nickname in the search bar, and find Arc Testnet in the list. Click Register and confirm the transaction. Your domain is now registered on the testnet.

Go to OnchainGM. Connect MetaMask again and select Arc Testnet. After clicking the button, a wallet confirmation window will open — this operation costs 0.5 USDC. Return to the main testnet site and check the status of your transactions on the blockchain.

Go to Syntra and click Get Started. After connecting your wallet, select the Arc network and the USDC token to swap for EURC. Set slippage to 5%. Confirm the transaction in your wallet — the task is complete. Immediately perform the reverse swap from EURC to USDC.

Go to Zkcodex, where you follow the same familiar flow: connect your wallet, select the Arc network among the icons, and make a transaction similar to OnchainGM.

The next protocol to work with is defi-on-arc. Here, also connect your wallet, switch to Arc Testnet, and perform a swap for an amount from $5: swap EURC for USDC.

Adding liquidity

In the Pool tab, select the EURC/USDC pair, enter the ratio of 1 USDC to 28 EURC, and sequentially click Approve, then Confirm.

Check that the liquidity was successfully added in your wallet.

In the Create Pool tab, you can create your own pool, but you need to farm 5,000 USDC beforehand.

Discord activities

Join the Build on Arc server via authorization.
Be sure to accept the server rules and answer the questionnaire questions. In the survey, indicate that you are a builder, influencer, or content creator, and write 2–3 sentences about yourself. The team conducts this moderation to filter out mass farmers. To the question “how should one behave on the server?” answer: “help each other, test the project, and leave feedback.”

There is currently no XP system on the server, but your activity will not go unnoticed. The more you interact with members, answer questions, and leave feedback (without spamming), the higher your chances of receiving special roles. Roles do not provide a 100% guarantee of an airdrop, but they definitely increase your chances of receiving one.
When the airdrop launches, the project team will identify the most active users and distribute tokens to them first. So you will definitely be among the earliest recipients who may receive a potential drop.
