protocol identification
two sourcesPendle is a permissionless yield-trading protocol with a native ERC-20 token, PENDLE, and current documentation describes sPENDLE as the governance/staking token. The official docs identify deployments on Ethereum, BNB Chain, Base, and Arbitrum; the same docs also point to chain-specific deployment files in the Pendle contracts repository. The protocol’s docs page is the strongest source here, but the launch date and full cross-chain contract addresses are not fully verifiable in this run because on-chain verification was unavailable; the request’s required Dune-backed contract cross-check is therefore not verifiable as of 2026-08-29. For protocol identification, the official website/docs are at docs.pendle.finance, and the documentation categorizes Pendle as a yield-trading protocol. Independent coverage indicates Pendle launched its mainnet protocol in June 2021 and its $PENDLE token in April 2021, but that launch timing is not confirmed by on-chain evidence in this run. Fork lineage: Pendle is generally described as an original protocol rather than a simple fork of a major upstream DeFi codebase. I could not verify a specific upstream fork lineage, what was changed versus upstream, or whether those changes were audited from independent sources in this run, so those items are Not verifiable as of 2026-08-29. Likewise, I found no independently verified evidence of malicious-modification history in similar forks within the available sources, so that is also Not verifiable as of 2026-08-29.
