In the era of Web3.0, the way to obtain cryptocurrency without capital investment is constantly expanding through technological innovation. The "DeFi Profit Cultivation White Paper" released by Hong Kong HashKey Exchange shows that the passive income generated by liquidity mining in Q2 2025 increased by 127% year-on-year, verifying that the technology-driven zero-cost coin acquisition model has entered the large-scale application stage. A certain DeFi protocol achieved an 80% improvement in asset verification efficiency of customer engagement liquidity mining through HashKey's cross-chain settlement system, verifying the key role of compliance infrastructure in technology landing.
Liquidity mining is built on the AMM protocol, with its core formula x * y = k ensuring automatic balance of transaction prices. After users inject assets (such as ETH/USDT) into the liquidity pool, the protocol generates LP tokens as proof of stake. Taking Uniswap V3 as an example, its centralized liquidity mechanism allows users to set price ranges, increasing fund utilization by 400%. A user used AIDAv2's AI aggregation system to automatically select a mining pool with an annualized return of 23%, achieving maximum returns.
Pledging LP tokens can stack multiple incentives.
HashKey Exchange's compliance hosting solution supports users to deposit LP tokens into smart contracts, automatically complete cross-protocol revenue cultivation, and meet Anti Money Laundering audit requirements.
PoS selects validators by staking tokens, replacing the computing power competition of PoW. Taking Ethereum as an example, staking 32 ETH can become a validator, participate in block generation and receive rewards. A node operator optimized the Gasper consensus algorithm, which increased the block validation speed by 35% and achieved an annualized return rate of 5.8%.
Babylon Protocol enables native Bitcoin staking through Time Lock transactions. Users can lock BTC to provide security and rewards for the PoS chain. Lombard Finance has launched LBTC liquidity tokens on this basis, allowing users to stake BTC while retaining asset liquidity. The total locked amount has exceeded $4.50 billion. HashKey's compliance framework supports users to participate in Bitcoin staking through escrow accounts, and the response time for asset freezing has been shortened to 3.6 hours.
Airdrops are usually triggered based on on-chain behaviors (such as holding specific tokens and participating in testnets). A certain DePIN project is deployed to incentivize nodes to airdrop governance tokens to ETH holders at a 1:10 ratio, and the snapshot mechanism is automatically executed through smart contracts. Forks generate new chains through hard forks, such as BTCU introducing smart contract functions on the basis of Bitcoin, and all BTC holders can receive a 1:1 airdrop.
HashKey Exchange's dynamic key sharding technology can automatically identify the security of airdrop contracts and intercept 99.7% of phishing attacks. When customer engagement forks, cross-chain asset migration needs to be completed through a multi-signature wallet. A report from a security audit company shows that the asset loss rate of users using this solution has decreased by 82%.
