DeFi Structure on Aptos Chain?

This year has seen a prominent feature: the combination of leading protocols has stabilized, with each protocol assuming its own role at different asset and risk levels. Echo, Aries, TruFin, Kofi, and Aptin—these five projects have long been in the top 10 by TVL, with a total locked asset value exceeding $370 million, becoming the main pillars of the financial layer on Aptos.
Echo continues to lead with a TVL of $270 million, mainly due to liquidity and aBTC restaking. Essentially, it serves as the gateway for BTC capital inflow to Aptos, facilitating the attraction and yield generation from Bitcoin cross-chain assets.
Aries holds about $42 million, attracting a large number of active users thanks to high LTV APT lending. Its role is as the main lending market, ensuring the circulation of stablecoins and APT.
TruFin, with $27 million, focuses on institutional staking/restaking and belongs to the group with more stable income, providing safe on-chain interest rates, closer to traditional financial logic.
Kofi offers MEV-optimized liquid staking with a TVL of around $20 million and an annual yield of 7-8%, ensuring long-term liquidity for Aptos’s PoS layer.
Aptin, with an algorithmic lending market of about $10 million, complements the on-chain interest rate structure, meeting the borrowing needs of small and medium investors.
Overall, these five projects cover almost all major financial flows on Aptos:
BTC → stablecoin → lending cycle → staking → restaking → yield strategies
This is the current stable DeFi structure of Aptos: the leading protocols are not competing but instead performing unique functions, forming a closed-loop liquidity flow on chain!
