Polygon's impressive TVL growth can be attributed to the success of its zkEVM, which offers lower costs and better scalability. This has attracted investors and led to a significant increase in TVL from $1.5 million to $14 million in a short period. MATIC may also be benefiting from this growth, as it has seen a bullish trend in the last five days. However, on-chain metrics suggest that MATIC's momentum may be slowing down due to selling pressure and a decrease in daily active addresses.
