As blockchains push for scalability, developer exercise has develop into one of many clearest indicators of which L1s would possibly stick round. However you may’t simply have a look at one metric. As an alternative, each fundamentals and actual on-chain utilization matter.
Consider it this manner: If a community is rising throughout sectors like DeFi, NFTs, and TVL, it normally means the underlying tech is strong. For blockchains, that tech usually comes all the way down to the good contract language powering the chain.
Proper now, Sui [SUI] and Aptos [APT] are the primary gamers, every making an attempt to win over builders and construct the following massive “Transfer” ecosystem. Nonetheless, information from Electrical Capital exhibits one chain is pulling forward.

Because the chart exhibits, Sui clocks 954 month-to-month energetic builders, 2x Aptos’ 465, highlighting its stronger traction with builders. Extra builders sometimes imply extra on-chain exercise, which helps a community scale extra shortly.
Notably, this on-chain power appears to have helped SUI climate the 2025 bear cycle higher. The L1 ended the yr down 65%, in comparison with APT’ 80.7% decline, reflecting its relative resilience amid market pressures.
However worth and developer numbers solely inform a part of the story. The true query is whether or not all that momentum is translating into precise development, like NFTs and different on-chain exercise. Put merely: Is SUI successful there, too?
SUI & APT in DeFi: How ‘Transfer’ displays chain momentum
For L1s, scalability is mainly the ticket to successful in DeFi.
Finally, the first use case for blockchains is to facilitate cash transfers with out intermediaries. So naturally, the L1 that may course of funds easily and run complicated DeFi apps tends to come back out on high.
The Whole Worth Locked (TVL) is a key option to measure this. Increased TVL normally means extra liquidity, extra exercise, and a stronger DeFi ecosystem general. On this context, SUI is pulling forward, with about 2x the TVL of APT.

From an operational perspective, this aligns intently with developer exercise.
Extra builders on SUI imply extra tasks being deployed, which boosts TVL. In different phrases, SUI’s lead in developer adoption is straight feeding its DeFi development, exhibiting the way it’s gaining an edge within the ‘Transfer’ developer conflict.
In the meantime, APT is clearly lagging on all three fronts (developer exercise, technical capability, and operational efficiency), exhibiting it nonetheless has some floor to make up if it desires to compete within the DeFi ecosystem.
Last Ideas
- SUI’s larger variety of energetic builders is fueling extra tasks, on-chain exercise, and general ecosystem momentum.
- With roughly 2× the TVL of APT, SUI is translating its developer lead into tangible DeFi development and community resilience.
