This video provides an in-depth tutorial on participating in the airdrop tasks for the sixth phase of the Tao blockchain testnet, Catla. This is the final testing phase before the mainnet launch, and it's expected that tokens will be issued for Gas. While participants in the first five testnet phases might have received more rewards, historical data suggests the final phase often yields the highest returns. The entire tutorial is conducted solely on the testnet, requiring no capital investment, making it ideal for zero-cost participants. Core operations include deploying smart contracts via ThirdWeb, transferring assets across multiple cross-chain bridges, minting community NFTs, registering Tao domain names, completing DEX token swaps, and performing social media tasks. The video also highlights the potential for high returns through running nodes, offering a VPS deployment guide. By completing these tasks, users can accumulate on-chain interaction records, boost their Gitcoin Passport score, and prepare thoroughly for future airdrop eligibility. The author also advises maintaining some activity on the older Joler testnet as a safeguard, in case it becomes a criterion for airdrop eligibility.
