ARC TESTNET COMPLETE AIRDROP GUIDE (DETAILED) If you are actively farming airdrops, @arc is one ecosystem you should not ignore right now. It is backed by Circle, has raised around $2.2B, and the $ARC token is already confirmed. The important part is that everything is still in the testnet phase, which means you can position yourself early without spending money. Arc is building a Layer-1 focused on bringing real-world financial activity on-chain. So instead of just doing random transactions, the idea is to behave like a real user across its ecosystem. This thread covers everything all dApps, all interactions, and a proper strategy. 1 . Claim Faucet > > Select Arc Testnet and claim USDC or EURC. Do this regularly. Wallets that show repeated activity over time generally stand out more than wallets that interact only once. 2 . INITIAL ONCHAIN FOOTPRINT Before jumping into DeFi, create some base activity: Deploy a contract: > Mint NFTs: > > Create your own NFT: > These actions help establish your wallet as an early and active participant rather than a passive one. 3 . ARC FLOW (CORE DEFI HUB) > This is one of the main hubs of activity. Complete social quests, mint the Activity NFT, and interact with core features like token swaps and liquidity. Adding and removing liquidity, even in small amounts, helps simulate real DeFi usage. 4 . TRADING AND LENDING > Here you should: > Claim CAT tokens from faucet > Trade those tokens > Use lending features supply, borrow, repay, withdraw > This step is important because it shows deeper interaction beyond simple swaps. 5 . SOCIAL INTERACTION > Set up your profile, post content, and interact with other users. Some ecosystems track social behavior as part of user engagement, so this is not something to skip. 6 . PREDICTION MARKETS > > > Use multiple platforms if possible. Create markets, place predictions, and interact with existing ones. Using more than one app increases your coverage across the ecosystem 7 . PRESTO DEX > Swap stablecoins and provide liquidity. You can also remove liquidity later and repeat the process over time to create consistent activity. 8 . DERIVATIVES (ADVANCED USAGE) > Trade derivatives and deposit into the Vault. Even small trades are enough. The goal is to show that you are exploring advanced features of the ecosystem. 9 . ARC WORLD > Mint Passport and Key NFTs, then interact with available games. This part adds a different type of engagement beyond financial ac 10 . FLOWFI > Deposit USDC, leave it for some time, and withdraw later. Simple actions like this help build a pattern of natural usage. 11 . NFT MINTING (ARKLE) > > Mint both collections and keep them in your wallet. NFT interactions often act as identity markers for early users. 12 . @TowerExchange (LIMITED ACCESS) > invite code After access: - Request faucet tokens - Swap and bridge assets - Use AI trading features - Create recurring buy/sell orders Projects like this often introduce point systems later, so early usage can matter. STRATEGY THAT ACTUALLY WORKS Do not treat this like a checklist you finish in one day. Spread interactions across multiple days. Repeat core actions like swapping, lending, and depositing. Use as many dApps as possible at least once. Avoid spam behavior interact normally. Consistency usually matters more than volume. Importent - Arc is still early, which is exactly where the opportunity is. Bookmark🥰
