In April 2021, Polygon (with a market capitalization of about 4 billion) offered $40 million worth of 1% MATIC to incentivize Aave (with a market capitalization of about 6.5 billion at the time), which was just the icing on the cake for AAVE at the time. In the Swap space: Uniswap was not officially deployed to Polygon until December 2021, and until then, QuickSwap had been dominant. In the lending field: Many protocols for fork mainnet lending products have also emerged on Polygon, but security is a concern, and countless attacks such as EZLend have occurred. The 40M incentive stacked more than 1 billion TVL, and Matic ran all the way from 0.4 to 2.6 in December 21, which is not entirely due to Aave, although it is not entirely due to Aave, but the impact is undoubtedly far-reaching. Unlike the current TVL of $1 billion, the cooperation between Polygon and Aave has long been regarded as a classic example of a win-win situation between public chains and applications, and has also become a template for later generations to follow. Fast forward to December 2024, sparking a heated debate over whether the $1.3 billion in assets in Polygon's cross-chain bridge should be placed on Morpho or Aave. Polygon hesitated for a while, but Aave expressed the risk of doing so and responded strongly, Aave adjusted the parameters of the Polygon lending platform, and the LTV was set to 0, which meant that no matter how many deposits were made, it could not borrow, froze liquidity, and even considered withdrawing from Polygon. As for Morpho, its story is quite dramatic. Initially just an interest rate optimization layer for Aave/Compound, it later launched Morpho Blue independently, rapidly expanding and competing for market share with its powerful BD capabilities, becoming Aave's most threatening opponent. Their strategy is to lobby all types of on-chain funders to migrate liquidity to Morpho as much as possible, thereby competing head-on with Aave. The above story inevitably raises several questions: Did Polygon have to choose Aave to cooperate with in the first place? Without AAVE, could Polygon's ecosystem launch so quickly? Or will security incidents occur frequently and no one cares? What exactly is Morpho's behavior? Is this market innovation or "eating other people's milk and biting back"? In the face of interests, does Polygon still remember the charcoal in the snow back then, or has it long since put that kindness behind? Aave's story continues, and a similar scene is repeated between WLFI and Aave. I dug it up again two years later. Are you afraid of products from Dough Finance? This is the case between projects, but what about people?
