#Lending and borrowing Tools

Maple Finance is onchain institutional credit: deposit stables, get lent to KYC’d trading firms and market makers against overcollateralized crypto (custodied offchain), earn the spread as yield. Retail front door is Syrup (syrupUSDC / syrupUSDT receipt tokens). Institutional side is permissioned pools and borrower tooling. Not Aave. Credit risk and withdrawal queues matter. Rebuilt hard after 2022 uncollateralized defaults. SYRUP is the governance token (ex-MPL).

JustLend DAO is the main lending protocol on TRON. Think Compound V2 style money markets: supply TRX and TRC20 assets (USDT is the big one), earn variable interest, borrow against collateral, get liquidated if you slip. Same app also does one-click TRX liquid staking (sTRX) and TRON Energy rental, which is why a lot of TRON users live here even when they are not looping loans. Huge TVL relative to the rest of TRON DeFi. JST is the governance / buyback token. Tied hard to TRON liquidity, USDT-TRC20 flows, and Justin Sun ecosystem politics.

Spark is the lending and savings front end of Sky (formerly MakerDAO). SparkLend looks a lot like Aave V3 because it is an Aave V3 fork tuned for DAI/USDS liquidity. You supply collateral, borrow stables, or park USDS in savings wrappers (sUSDS / older sDAI) that earn the Sky Savings Rate. Sky can mint liquidity into Spark via D3M-style modules, which often keeps USDS borrow rates competitive. Big TVL. Tightly tied to Sky governance and stablecoin health. Not a standalone money market in spirit.

EigenCloud (perv. EigenLayer) is Ethereum’s main restaking marketplace. You take already-staked ETH (or LSTs like stETH) and opt that capital into securing extra services called AVSs, for extra rewards and extra slashing risk. Operators run the software. Most people touch it through liquid restaking tokens (ether.fi and peers). Dominant restaking TVL. Infrastructure play, not a simple savings APY. Slashing is live. Complexity is the tax.

Morpho is a DeFi lending stack built in two layers. Morpho Blue is a tiny, mostly immutable engine for isolated loan markets. MetaMorpho vaults sit on top so curators pick markets and you just deposit for yield. Think “Aave-like deposit UX” with less shared-pool contagion and often tighter rates. TVL sits in the multi-billion range and trails only Aave among pure lenders. You trade DAO risk-parameter theater for curator-selection homework.

Aave is the main DeFi money market. You supply crypto to earn interest or borrow against collateral you already deposited. No bank account. Wallet connects, smart contracts hold the pools. V3 runs on Ethereum plus many L2s (Arbitrum, Base, Optimism, and more). Rates move with utilization. Borrowers live or die by a Health Factor. Biggest lending protocol by TVL for years. Powerful, liquid, and unforgiving if you ignore liquidations.
