Split yield-bearing assets into principal and yield tokens. Structured finance on-chain without the regulatory framework.
"The investor's custody account — holds yield-bearing asset (stETH, USDY, eETH, GLP, LST), no identity check, permissionless deposit."
User self-custody wallet on Ethereum (or Arbitrum) holds yield-bearing collateral (stETH, Lido LST, USDY, eETH, GLP, or other interest-accruing token) and prepares to deposit into Pendle for yield tokenization. The protocol is permissionless — no KYC, no whitelist, no identity layer. L4 Account (token balance, approval) and L5 Application (wallet UX, Pendle interface) are lit. HONESTY MARKER: D1 (Identity) is required by GENIUS Act and BSA, but Pendle Protocol enforcement is absent. The protocol cannot identify users, cannot freeze addresses. Compliance is structurally absent at the protocol level.
"Bond tranching desk splits a bond into principal strip and interest strip — except permissionless, instant, and code-enforced."
User deposits yield-bearing asset into Pendle smart contract. The protocol splits the deposit into two synthetic tokens: PT (Principal Token) and YT (Yield Token). PT is a zero-coupon bond — it accrues no interest but matures to the underlying asset value (1 PT = 1 unit of underlying at maturity). YT is the floating-rate yield stream — it represents all future yield accruing between deposit and maturity. This split is instant and code-enforced. HONESTY MARKER: This replicates structured finance tranching (CDO waterfall, bond stripping, interest-only / principal-only strips) without any regulatory framework. In TradFi, bond tranching requires SEC registration, prospectus, suitability checks, redemption statements. On Pendle, anyone can tranche any asset permissionlessly. The maturity date is hardcoded into each PT/YT pair — it is immutable and code-enforced.
"Bond trading on secondary market — PT and YT trade independently, each with market-determined price."
After split, PT and YT trade on Pendle's custom AMM. The AMM is optimized for time-decaying assets: YT loses value asymptotically as maturity approaches, converging to zero. PT converges to the underlying asset value. Users can buy PT for fixed-yield strategies (PT price at purchase determines effective yield to maturity) or buy YT for leveraged yield exposure. Sellers of PT provide leverage to buyers. YT sellers are short yield — if actual yield outpaces the priced-in yield, YT holders profit; if yield underperforms, they lose. This is permissionless trading with no restrictions on counterparties. D13 (Market Integrity) is code-enforced: price discovery is algorithm-driven, oracle-checked. D16 (Programmable Compliance) is absent — Pendle cannot restrict traders, cannot enforce country checks.
"Bond maturity date — as date approaches, principal and yield accrue forward. Automated redemption on maturity."
As the maturity date approaches (hardcoded in the PT/YT pair), market prices converge to their maturity values: PT → 1 unit of underlying asset, YT → 0 (since all yield has been distributed to holders). At maturity, YT expires worthless — no further yield accrues, YT cannot be redeemed. PT remains redeemable. This is all code-enforced: no human intervention, no governance override. The maturity date is immutable and non-negotiable. HONESTY MARKER: This replicates the risk profile of structured finance tranching and bond maturity. In TradFi, maturity is governed by indenture law and backed by trustee oversight. On Pendle, maturity is code-enforced but has no legal backup if the underlying protocol fails or the yield assumption breaks.
"Bond redemption. PT holders redeem for principal; YT holders receive zero (yield already claimed)."
At maturity, PT holders redeem their tokens for the underlying asset 1:1. If user bought PT for stETH at maturity date T, redemption returns exactly 1 stETH (minus any accrued fees). YT holders have already collected yield; YT expires worthless and cannot be redeemed. Redemption is permissionless and code-enforced — no discretion, no gate, no approval required. Recordkeeping is the on-chain transaction receipt and transfer events (D11); no traditional AML alert or CTR filing. HONESTY MARKER: Pendle has grown to $5B+ TVL at peak, with institutional interest in fixed-rate stablecoin yields (e.g., Pendle PT of USDY for treasury strategies). However, no entity has custody of funds during maturity — users are self-custodied throughout. If the underlying asset (e.g., stETH) faces a liquidation spiral or protocol risk, Pendle has no recovery mechanism. The maturity guarantee is only as strong as the underlying protocol.
