On-chain lending is no longer just a game for crypto enthusiasts. From what I’ve observed, it’s gradually transforming into a massive savings machine.

$643 billion in TVL, or total value locked. This figure isn’t just a number — it reflects thousands of individual and institutional decisions behind it. 53% of all DeFi sectors are in lending alone. This indicates how central this area has become.

Aave currently controls over half of the market with $329 billion. Compound is in second place, but only with $26 billion — ten times less than Aave. This "one dominant, many strong" pattern isn’t expected to change in the next few years.

But interesting things are happening here. Aave isn’t just huge — it’s continuously evolving. Version 4 is coming mid-2026, featuring cross-chain clearing and an institutional compliance framework. Morpho Labs is working behind the scenes as an optimization layer — increasing capital efficiency through P2P matching. Spark Finance, deeply integrated with MakerDAO, remains strong in stablecoin lending.

On a technical level, three distinct paths are emerging. First: liquidity pool models (Aave, Compound) — more liquidity but less capital efficiency. Second: P2P matching (Notional Finance, Myso Finance) — stable interest rates but limited liquidity. Third: permissionless pools (Euler Finance V2, Ajna) — fully market-driven, but with user education challenges.

A revolution is happening in stable interest rates. Notional was the first to offer fixed-term loans. Pendle divided yield into Principal Token (PT) and Yield Token (YT). In 2024, Pendle’s TVL increased tenfold — from $100 million to $10 billion. PENDLE is now at $1.30, but given the pace of this innovation, it’s worth paying attention.

The biggest shift is happening in RWA (Real World Assets). Over $185 billion in RWA lending is now on-chain. U.S. government bonds, corporate credit, real estate — these are now the main securities. Ondo Finance’s OUSG exceeds $10 billion. Maple Finance is working with institutional borrowers. Centrifuge is in physical asset financing. It’s functioning like a savings machine — stable, predictable, institutional.

But risks are real. Clearance waterfall — when prices drop rapidly, chain-linked clearances occur. This was seen during the 2022 UST/Luna collapse. Credit default — in November 2022, Orthogonal Trading lost $36 million on Maple. Cross-chain security — Ronin Bridge had to endure a $625 million attack in 2022.

My strategy: main position in the Aave ecosystem (AAVE currently at $93.45, +1.51% in 24h). Supporting positions in RWA and stable rate innovations. MORPHO ($1.87, -2.29%) and PENDLE ($1.30, -0.53%) both present alpha opportunities. Centrifuge (CFG at $0.25, +3.35%) is interesting in physical asset financing.

This savings machine is evolving — from crypto-native leverage tools to institutional financial infrastructure. Those who understand this shift will be well-positioned in the next cycle.
