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.

  name: Pendle Backend Data API
  description: 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.

    precision levels and mirrors the payload shape of the REST endpoint `GET /limit-order/v2/order-book/:chainId`.

    or short positions on yield rates with a cross-margin or isolated-margin account model and an Agent trading pattern that
    delegates signing to scoped subaccounts. The HTTP API is the integration backbone for bots, market-makers, and analytics.
