ARC Testnet Tutorial 2026 Step by Step Guide to All On Chain Operations

ARC testnet is live and builders can already run real transactions using stablecoins as gas. That makes this network feel different from most testnets. You will use testnet USDC to pay fees, you will move value, and you will touch key apps in the Arc ecosystem. Arc also publishes clear setup details, so you can start fast.

Key Takeaways

• Arc Testnet uses USDC as the gas token, so you need testnet USDC before anything else.
• You can get testnet USDC and EURC from Circle’s faucet, then test transfers, swaps, and liquidity actions.
• Most on chain operations follow standard EVM flows once you add Arc Testnet to your wallet.

Step 1 Connect Wallet and Fund ARC Testnet With USDC and EURC

This ARC Testnet guide starts with a clean wallet setup. Use MetaMask or any EVM wallet that supports custom networks. Arc publishes the parameters you need.

Add Arc Testnet to MetaMask

1. Open MetaMask
2. Select Add network then Add a network manually
3. Enter these fields
   • Network name: Arc Testnet
   • RPC URL: https://rpc.testnet.arc.network
   • Chain ID: 5042002
   • Currency symbol: USDC
   • Explorer: https://testnet.arcscan.app
4. Save and switch to Arc Testnet

Important detail. Gas is paid in USDC on Arc. That is a core design choice, so do not look for test ETH on Arc for fees.

Claim faucet tokens

Now claim ARC faucet USDC EURC.

1. Open Circle Testnet Faucet
2. Select network: Arc Testnet
3. Select token: USDC, then request to your wallet address
4. Repeat for EURC

Arc also exposes the contract references you may need for apps and explorers. For Arc Testnet, USDC has an optional ERC20 interface at 0x3600000000000000000000000000000000000000, and EURC is at 0x89B50855Aa3bE2F677cD6303Cec089B5F319D72a.

Tip that saves mistakes. Arc notes a decimals nuance. Native USDC gas uses 18 decimals precision, while the USDC ERC20 interface uses 6 decimals. If you build scripts, always read decimals from the contract.

Step 2 Bridge Sepolia to ARC and Complete Core Testnet Tasks

Many users ask about ARC testnet airdrop. There is no official promise to reward testnet users. Treat this as learning and ecosystem testing first. Still, if you want broad coverage of ARC testnet tasks, do a set of repeatable actions that touch different contract types and apps.

Bridge Sepolia to ARC

If your goal is bridge Sepolia to ARC, Arc’s official docs focus on bridging USDC programmatically using Circle Bridge Kit and CCTP. That is the most documented path today.

A simple user flow looks like this:

1. Hold testnet USDC on Ethereum Sepolia in your wallet
2. Follow the Bridge USDC to Arc tutorial using Circle Bridge Kit
3. Create or use wallets, fund them, then run the bridge script
4. Verify the transfer on Arc explorer

If you are not coding, you can still follow the same concept. You are moving USDC across chains using CCTP style burn and mint. The key is that Arc expects USDC for gas, so bridging or faucet funding comes first.

Listicle checklist of ARC testnet tasks

Use this list to create on chain history across the most common actions.

1. Faucet claim USDC on Arc
2. Faucet claim EURC on Arc
3. Send a small USDC transfer to a second wallet
4. Send a small EURC transfer to the same wallet
5. Do a DEX swap USDC to EURC on a supported DEX in the Arc ecosystem
6. Do a swap back EURC to USDC
7. Add liquidity to a stable pool
8. Remove a small portion of liquidity
9. Approve a token spend in a new contract
10. Repeat one action on a different day to show consistent usage

For DEX and liquidity, Arc highlights major liquidity and trading builders that support the network, including Curve and Uniswap Labs among others, which signals that swap and pool actions are key parts of the testnet experience.

Step 3 Deploy NFT, Create ERC20, Swap, and Test Liquidity Farming Flows

This section covers the advanced ARC Testnet guide operations you asked for. Arc is EVM compatible, so the mechanics mirror Ethereum. The main difference is gas in USDC and the Arc network settings.

Deploy an NFT on ARC testnet

You can use Remix or any standard tool.

1. Open Remix and create an ERC721 contract using a trusted template
2. Compile the contract
3. Connect MetaMask in Remix
4. Switch MetaMask network to Arc Testnet
5. Deploy the contract
6. Mint one NFT to your wallet
7. Confirm mint on the Arc explorer

This completes deploy NFT on ARC testnet and creates multiple transaction types: deploy plus mint.

Create an ERC20 token on ARC

1. In Remix, create an ERC20 contract
2. Set name, symbol, and initial supply
3. Compile
4. Deploy on Arc Testnet
5. Call transfer to send tokens to a second wallet
6. Call approve to allow a DEX router or another contract to spend tokens

You now satisfy create ERC20 token ARC and also generate approve events that many apps rely on.

ARC DEX swap tutorial and liquidity farming style actions

On a supported DEX in the Arc ecosystem:

1. Connect wallet on Arc Testnet
2. Swap a small amount USDC to EURC
3. Swap back EURC to USDC
4. Open Pools
5. Add liquidity to a USDC EURC pool
6. Confirm the pool token receipt in your wallet
7. Remove a small amount later to record exit behavior

If a testnet app offers incentives or farming style flows, the actions usually look like this:

1. Add liquidity
2. Stake LP token
3. Claim test rewards if enabled
4. Unstake and withdraw

Even if rewards are just test values, this is the typical ARC liquidity farming testnet path.

Final safety note. Always use test funds only. Circle faucet tokens are for testing, not for profit.

Conclusion

ARC Testnet in 2026 is a practical playground for payments, swaps, and smart contracts, with a stablecoin first design that uses USDC for gas. Start by adding Arc Testnet to your wallet, then claim testnet USDC and EURC from Circle’s faucet. After that, bridge Sepolia to ARC if you want cross chain practice, run DEX swaps, add liquidity, and deploy simple ERC20 and NFT contracts. Keep your actions small, repeat them over time, and treat any airdrop talk as speculation unless Arc confirms it officially.
