As a seasoned Web3 enthusiast who's been diving deep into blockchain ecosystems for years, I've seen how testnets like ARC can be a goldmine for early adopters. If you're just getting started, make sure you've got the basics down on ARC's testnet setup and how to claim those test tokens—I've covered that in my previous posts. Today, I'm excited to walk you through some hands-on interactions with popular projects on the network. These steps aren't just busywork; they're your ticket to boosting on-chain activity, which could seriously amp up your chances for future airdrops in this buzzing space.

  1. DeFi On ARC

Let's kick things off with swapping tokens. Start by linking your wallet and flipping the network switch to ARC's testnet—it's a quick setup that gets you right into the action.

Head over to the swap interface and execute a few token exchanges. Aim for transactions worth at least $5 each to mimic real-world volume, and don't stop at one—variety keeps your profile looking engaged and dynamic.

Once you've swapped, give the cross-chain bridge a spin—it's currently geared toward USDC. Try shuttling assets back and forth between chains to build that cross-network footprint, something savvy DeFi users swear by for visibility.

Next up, dive into liquidity provision. Add some to a pool, then pull it back out. Repeating this cycle a handful of times? It's a smart way to rack up interactions without any real risk, much like testing the waters in a new DeFi pool before committing big.

  1. Sendly

This platform shines for seamless cross-chain moves, but it also packs in fun social perks like sending or receiving digital "namecards"—think of it as networking in the blockchain world, where every connection counts toward your ecosystem involvement.

  1. Stable Vault

After connecting your wallet, experiment with deposits and withdrawals. Go back and forth a few times to simulate everyday usage—it's the kind of organic activity that makes your on-chain history pop, especially in a test environment where you're honing skills for the mainnet rush.

  1. Arc Payroll

Set up a mock company to get the ball rolling—it's straightforward and sets the stage for more intricate plays.

From there, onboard an "employee" (maybe a secondary wallet of yours) and process a payroll payout. This payroll simulation adds a layer of real-world utility to your interactions, echoing how Web3 could streamline freelance gigs in the gig economy.

  1. Bagless

Launch your own test token—it's an empowering first step into token creation that feels straight out of a crypto builder's toolkit.

Follow it up with swaps and liquidity additions to flesh out your token's presence on the network.

Wrap with a cross-chain transfer to connect the dots across ecosystems.

  1. Token Deployer

Deploy a smart contract to cap off your session—it's the ultimate flex for showing technical chops on the testnet.

In wrapping this up, remember that the real win on ARC's testnet is ramping up your on-chain engagement and weaving yourself deeper into the fabric of its growing community. These zero-cost maneuvers are a breeze, so make it a habit—hit them daily or every other day. Before you know it, you'll be positioned front and center for whatever airdrops come down the pike, turning testnet tinkering into tangible rewards.
