Pendle Finance

kind: opensource
description: >-
  Pendle Finance is a decentralized yield-trading protocol that tokenizes
  future yield by stripping yield-bearing assets into Principal Tokens (PT)
  and Yield Tokens (YT) wrapped in a Standardized Yield (SY) layer. PT trades
  at a discount and matures one-to-one for the underlying at expiry, giving
  buyers a fixed yield; YT entitles holders to the variable yield until
  expiry, letting them long, hedge, or speculate on yield itself. Pendle V2
  pairs this with a purpose-built AMM for trading time-decaying assets, and
  Boros extends the design into a margin venue for trading yield as a
  perpetual rate. The protocol is live on Ethereum, Arbitrum, BNB Chain,
  Optimism, Base, Mantle, Sonic, Berachain, HyperEVM, Monad, Katana, and Ink.
  Developer surface includes the Pendle Hosted SDK (a REST API for generating
  Pendle transactions), a Backend Data API for market, asset, price, and
  governance data, Socket.IO real-time feeds, the Boros TypeScript SDK and
  Boros HTTP API, vePENDLE / sPENDLE governance, and audited open-source
  Solidity contracts for V2 cores, SY wrappers, and Boros core.

    name: Pendle Hosted SDK API
    description: >-
      A hosted REST API that generates ready-to-broadcast calldata for every
      Pendle protocol action — swap (including tokens-to-PT, PT-to-tokens,
      YT swaps), add and remove liquidity, ZPI (zero-price-impact) flows,
      mint and redeem PT/YT, mint and redeem SY, transfer liquidity, roll
      over PT positions, and dual-sided liquidity. Most operations go
      through a single universal Convert endpoint
      (`POST /v3/sdk/{chainId}/convert`) that accepts tokens in, tokens out,
      amounts, receiver, slippage, optional aggregator selection (KyberSwap,
      etc.), and additional analytics flags (impliedApy, effectiveApy). The
      hosted SDK tracks Pendle UI behaviour exactly and is updated whenever
      underlying SY assets evolve, so integrators do not have to patch
      client SDKs to follow protocol changes.

      REST API for offchain Pendle data — markets, assets, prices, user
      positions, transactions, points, and governance. Cross-chain endpoints
      (`GET /v2/markets/all`, `GET /v1/assets/all`, `GET /v1/prices/assets`)
      return data spanning every supported chain in one call and are the
      recommended entry points for new integrations. Chain-scoped endpoints
      (`/v3/{chainId}/markets/{address}/historical-data`,
      `/v5/{chainId}/transactions/{address}`) provide deep market history
      with optional APY breakdown and per-address transaction history. The
      pricing response includes a partial-success `errors` array so callers
      can handle non-fatal missing-asset cases without retrying.
