PendleLoop Adds wstETH, sUSDe and Waives Non-PT Fees

Pendle expanded PendleLoop to support wstETH and sUSDe, according to the company, while waiving fees on non-principal-token loops through Dec. 31, 2026. The announcement introduces two yield-bearing assets to a product that separates principal exposure from yield and combines those positions with leveraged trades in either direction.

The fee waiver applies specifically to non-principal-token, or non-PT, loops. It does not cover every PendleLoop transaction. The Dec. 31, 2026 expiration gives market participants more than six months to test the expanded asset set without paying the applicable loop fees, although the announcement does not disclose the fee rate before or after the waiver.

PendleLoop uses a two-claim structure to package yield-bearing assets. The protocol converts each asset into one claim tied to principal and another claim tied to yield. Users can then combine the yield strategy with leveraged exposure that moves in their chosen direction.

What does this change for PendleLoop users?

The additions give users access to wstETH, Ether’s liquid staking token, and sUSDe within the same looping framework. That widens the range of yield strategies available to participants who separate principal from yield, while the non-PT fee waiver lowers the cost of deploying those strategies during the promotional period.

The product already supported Ether staking, stablecoin and real-world asset strategies. Pendle also previously added a looping option for Sky’s yield-bearing sUSDS. The wstETH and sUSDe releases extend that support to two additional assets rather than creating a new looping mechanism.

The distinction between principal and yield is central to how PendleLoop operates. Principal tokens represent the underlying deposited asset, while yield tokens isolate the return generated by the strategy. By trading those claims separately, users can retain exposure to one component while applying leverage to the other.

For practitioners, the immediate question is whether the wider asset coverage produces deeper liquidity and tighter execution across more markets. The source does not provide trading-volume, liquidity, user or revenue figures, so it does not support a conclusion about adoption or market impact.

Pendle’s structure also places a valuation emphasis on the yield claim rather than forcing users to evaluate principal and return as a single position. That separation can make the economics of a leveraged loop more granular, but it also leaves users exposed to the pricing, liquidity and counterparty conditions of both markets.

The announcement does not specify a launch date for either asset, the fee schedule after Dec. 31, 2026, or the exact assets eligible for the waiver. Those details will determine whether the promotion becomes a sustained change in PendleLoop’s market structure or remains a time-limited incentive through the end of 2026.
