Element Protocol primary sources

Collected: 2026-05-11 UTC

Primary sources reviewed

• https://github.com/delvtech/elf-contracts
  • Public smart-contract repository
  • Used to confirm the protocol’s own description of PT/YT splitting, YieldSpace-derived AMM design, community-extension framing, and permissionless launch surface
• https://github.com/delvtech/elf-contracts/blob/master/SPECIFICATION.md
  • Contract specification
  • Used to confirm wrapped-position integration, tranche minting and redemption behavior, late-entry discounting, Yield token behavior, negative-yield speedbump logic, and Balancer-based convergent-curve pool design
• https://github.com/delvtech/docs-portal
  • Public docs portal repository
  • Used to confirm the user-role split between fixed-rate buyers, variable-rate depositors, and liquidity providers
• https://docs-delv.gitbook.io/element-protocol-developer-docs/element/principal-tokens
  • Developer docs for PTs
  • Used to confirm the discounted-fixed-term PT framing and the explicit liquidity-before-maturity positioning
• https://docs-delv.gitbook.io/element-protocol-developer-docs/element/yield-tokens
  • Developer docs for YTs
  • Used to confirm that YTs represent the uncertain yield earned over the defined term on the represented principal

Notes

• Element’s key mechanism is not just “fixed yield.” It is a clean decomposition of one yield-bearing position into a discounted future-principal claim plus a residual variable-yield claim, with explicit maturity and dedicated secondary-market pricing.
• The YieldSpace / Balancer integration matters because Element is not only a token split; it also bundles a specific market-making answer for how fixed-income claims should trade before maturity.
• The late-entry discount rule and the negative-interest speedbump are especially worth retaining because they expose how tranche systems handle already-accrued yield and adverse underlying performance, two details that later PT/YT systems often obscure.
• The docs-portal user taxonomy is analytically useful: it makes clear that buying PTs at a discount is the fixed-rate trade, while minting PTs and YTs is a different economic action.
• This entry belongs in the active corpus because it gives the Pendle / Sense / Spectra branch a stronger historical baseline and helps separate yield tokenization, AMM design, maturity logic, and loss handling instead of flattening them into a generic fixed income DeFi label.
