I have been tracking for the past few days.

@Theo_Network
The update, today I saw a key point:
PT-$thBILL has officially integrated with Euler.

The significance of this matter is far deeper than just "adding a new lending pool."

My first reaction is:
$thBILL has evolved from "on-chain government bonds" into a recognized underlying collateral asset between protocols.
This is a role conversion at the ecological level.

On Arbitrum, PT-$thBILL can be directly used as collateral to borrow $USDC, $USD₮, and even native $thBILL.
In the past, such treatment was only reserved for "established underlying assets" like ETH, stETH, and high-quality liquidity LPs.
Now that a basket of government bonds can enter this level, it indicates that the risk control of the agreement has already provided the most core judgment:
Trustworthy, stable, and composable.

I looked back and carefully deduced the entire path again, and the more I looked, the clearer it became:

Pendle —— Splits the yield structure of $thBILL into PT / YT

Euler —— Integrate PT-$thBILL into the interest rate and lending system

Arbitrum —— Provides a low-friction execution environment

Theo —— Provides underlying assets, real returns, and custody security guarantees

From a system perspective, this is not simply RWA tokenization, but rather:
Bringing the yield and maturity structure of traditional government bonds fully onto the blockchain and enabling its composability.

In other words, $thBILL has transitioned from a static asset to a dynamic interest rate component capable of participating in on-chain mechanisms.

The current $thBILL is no longer just:

Let it sit and earn returns.

Waiting for arbitrage

It has begun to possess:

✔ Staking Quality
✔ Enter the lending market
✔ Split into term assets
✔ Build structured products
✔ Become the asset underlying the protocol's treasury

These features are extremely rare in the RWA field.
Most projects stop at "making products".
What Theo is building is a composable asset layer.

Logging into Euler PT-$thBILL may seem like "just going online," but in the context of the interest rate market, it actually means:
The national debt will first serve as a rate-bearing primitive on the blockchain.

Phenomena that I can basically expect to occur in the coming months:

• More agreements will include $thBILL in the treasury.
• More collateral pools will accept PT-$thBILL
• Structured strategies will revolve around thBILL
• The secondary curve of thBILL will appear in the interest rate market.
• $thBILL itself may evolve into a "cash layer asset" on the chain.

From the perspective of composability and systemic risk mitigation, this route is already very clear.

To me, the level of this matter > "Launching a pool."
It is the first time that RWA truly enters the core layer of DeFi and begins to take on more complex and diverse roles than TradFi.

Worth tracking continuously.
