Citadels were introduced to provide institutional and Shariah-compliant access to on-chain yield products, signaling moves to broaden eligibility and encourage regulatory-conscious participation in yield trading.

The DeFi yield trading landscape is consolidating around Pendle, as former competitors have rebranded or exited, reinforcing Pendle’s position as the de facto monopoly in yield trading and drawing ongoing interest from institutions and investors such as Arthur Hayes, Binance Labs, and Spartan Group.

Pendle has expanded beyond Ethereum to more than eight blockchains, including Solana and TON, and rolled out Boros (V3) in 2026 to trade perpetual funding rates, targeting about $150 billion in daily funding-rate volume; early testing yielded $5.5 billion in notional volume and roughly $730,000 in initial revenue.

The protocol tokenizes yield-bearing assets into Principal Tokens and Yield Tokens, enabling trading and fixed-return locking, while innovations like Automated Market Maker v2 for time-decaying assets and the Standardized Yield framework under EIP-5115 boost cross-application composability.

Pendle generates over $40 million in annual revenue from trading activity, with 80% allocated to token buybacks under the sPENDLE model introduced in 2026, amounting to around $32 million yearly for buybacks and marking a shift away from the previous vePENDLE model.

Pendle Finance remains the leading DeFi yield trading protocol, commanding roughly half to a little over 60% of the market and overseeing total value locked exceeding $5 billion as of 2025, with limited direct competition.
