Spectra
Credit · Fixed Income · SPECTRA
Spectra (formerly APWine) is a permissionless interest-rate derivatives protocol: any yield-bearing asset can be split into principal and yield tokens to trade fixed and variable rates.

Risks identified
- Smart Contract
Spectra tokenizes yield-bearing positions through PT/YT contracts, AMM pools, and a router. Its Code4rena audit surfaced a medium-severity finding on potential yield drainage via flash-loan exploitation of a vault-deflation attack, and another on ERC-5095 compliance; permissionless pool creation enlarges the attack surface since anyone can list arbitrary ERC-4626 vaults.
- Reserve / Depeg
A Principal Token's fixed-rate guarantee depends on the underlying ERC-4626 vault redeeming 1:1 at maturity. If the underlying yield-bearing asset (a lending receipt, LST, or stablecoin) depegs or loses value, PT redemption value falls and holders can be under-collateralized despite holding the 'principal' leg.
- Counterparty
Spectra is a yield layer sitting on top of external protocols (Aave, Lido, stablecoin issuers, etc.). A failure, exploit, or insolvency in any integrated underlying protocol flows directly through to the PTs/YTs minted against it, so users inherit the counterparty risk of every underlying vault they hold exposure to.
- Governance
Emissions, gauge weights, and fee distribution are controlled by veSPECTRA voters, and the AMM/tokenomics were forked from Velodrome/Curve designs. Concentrated veSPECTRA holdings could steer incentives or fee parameters (e.g. changes made via SIP/SGP proposals) in ways that disadvantage ordinary LPs or PT/YT holders.
- Network
Governance, gauge voting, and reward claims were migrated to the Base network (an L2). Base sequencer downtime, reorgs, or bridge issues could disrupt voting and reward claiming, and multi-chain deployment exposes users to the liveness and security assumptions of each chain the protocol operates on.
