Imagine you're building something with money.
You want to save it, lend it, borrow it, trade with it, and move it around.
But there's one problem:
Crypto prices move. A lot.
If you lend $1,000 worth of SOL today, its value could be very different tomorrow.
That makes everyday financial activity harder to predict.
This is one reason stablecoins became so important to DeFi.
A stablecoin is a crypto asset designed to maintain a relatively stable value, often around a reference currency such as the US dollar.
For example, a token like USDC is designed to track the value of $1.
Think of it as a digital representation of a more stable unit of account that can move around on a blockchain.
Why does that matter?
Imagine you sell your SOL for USDC.
You may still want to stay inside the crypto ecosystem, but you don't necessarily want your money exposed to SOL's price movements.
You can hold the USDC, lend it, borrow against other assets with it, or use it in a DeFi application.
Stablecoins therefore act as a kind of bridge between volatile crypto assets and a more stable unit of value.
And they're not only useful for traders.
Remember our lending example?
A lender can supply USDC.
A borrower can deposit crypto as collateral and borrow USDC.
Now both sides are using an asset designed to stay close to $1.
That makes the lending process much easier to understand.
But here's the important part:
"Stable" doesn't mean "risk-free."
Different stablecoins use different mechanisms to maintain their value.
Some are backed by assets or reserves.
Others use crypto collateral or other mechanisms.
And those mechanisms can fail, which means a stablecoin can lose its intended value.
So don't think of a stablecoin as simply "a cryptocurrency that cannot move."
Think of it as:
A crypto asset designed to maintain a relatively stable value.
That simple idea has become one of the foundations of DeFi.
We've now seen how people trade, provide liquidity, farm, stake, lend, borrow, and use stablecoins.
But there's a problem we haven't solved yet:

For example, how would a DeFi protocol know the current price of SOL?
That's where oracles come in.

Last time, we looked at DeFi borrowing.
You could deposit crypto as collateral, borrow another asset, and avoid selling what you already own.
But that leaves one side of the equation:
Who is providing the money being borrowed?
Other users.
DeFi lending works because someone is willing to supply their assets to the protocol.
And why would they do that?
To earn interest.
Imagine you have 1,000 USDC sitting unused in your wallet.
Instead of leaving it idle, you could deposit it into a lending protocol.
Another user may want to borrow USDC.
They provide collateral, borrow from the available pool, and pay interest on the loan.
Part of that interest can go to the people who supplied the USDC.
So the basic cycle looks like this:
Lender → supplies assets → protocol → borrower → pays interest → lender
The protocol sits between both sides and uses smart contracts to enforce the rules.
But here's something important:
The lender isn't simply handing their money directly to another person.
The assets are supplied to a protocol, and the protocol determines things like borrowing limits, interest rates, collateral requirements, and what happens when a borrower becomes undercollateralized.
This creates a permissionless lending market where users can participate on either side.
You can be the person earning interest.
Or you can be the person paying interest to access liquidity.
And unlike a traditional bank loan, you generally don't need to negotiate with a loan officer or submit the same kind of paperwork.
But there's still risk.
The protocol could have vulnerabilities.
The assets involved can change in value.
And the amount of interest you earn can change depending on supply and demand.
So remember:
Lending in DeFi isn't about giving away your crypto. It's about supplying capital to a protocol in exchange for potential returns.
Now we've covered both sides of the lending market.
But there's another asset you'll constantly encounter throughout DeFi:
Stablecoins.
Why would anyone create a crypto token designed to stay close to the value of $1?
And why are stablecoins so important to DeFi?
That's the next piece of the puzzle.

## @EMEBOK_ (EMEBOK 🥷🕸️) · 09-29 05:16 · ♥44 ↻4 💬3 one of the small things that can make using crypto inconvenient is needing the network's native token just to send stablecoins.
#GasFree helps address that by letting users transfer USDT or USDD without holding TRX for gas.
it's now making an appearance at GWDC 2026 Korea in Seoul, giving attendees a chance to learn more about how it works.

Got USDT or USDD to move but no TRX in your wallet? No problem. #GasFree is at #GWDC 2026 KOREA.
Take a closer look at GasFree and see how it works. 🙌 #GasFreeGWDC https://t.co/Y0sZhJMJww https://x.com/EMEBOK_/status/2104802470450913378
