Spectra V2
Spectra V2 is a permissionless interest-rate-derivatives protocol that splits interest-bearing tokens into principal and future-yield claims and supports fixed-rate, yield-trading, and LP positions. The August 15, 2026 survey reported about $30.0M across twelve chains, still well below the size floor after higher-order exclusions. At this size, an advised book could become a meaningful share of executable market liquidity. The individual review will not open until the protocol shows sustained scale above the floor. Then each PT, YT, or LP position and its underlying yield source must be reviewed separately. Clearing the floor would not imply approval.
- TVL sustained above the retired TVL threshold for 30 days

The research file
Applicability to the surveyed record
Spectra V2 splits an ERC-4626-compatible interest-bearing token into Principal Tokens that represent principal and Yield Tokens that represent future yield. Its permissionless markets support fixed-rate PT purchases, variable-yield or points exposure through YT, and PT/IBT liquidity positions. These facts establish the current protocol identity, but the review does not treat those economically different positions as one product.
Current observation and perimeter
The DefiLlama protocol API read on 2026-08-15 reported approximately $30.01M TVL across Hemi, Flare, Avalanche, Ethereum, Katana, Base, Sonic, BNB Chain, Hyperliquid L1, Optimism, Arbitrum and Monad. That is less than one third of the shared v1 size floor. Hemi and Flare held the largest balances.
Control, loss and exit applicability
Anyone can create a market with a compatible interest-bearing token, target rate and maturity. Each position therefore depends on the underlying token and protocol, not a curated Spectra endorsement. Spectra warns that negative yield reduces PT backing. PT holders can wait for maturity and redeem, or sell earlier into available pool liquidity at the executable price. YT expires, and LP exits add their own rate, path and liquidity risks.
Why the shared dossier decides
The v1 below-materiality dossier decides the result before any product-level review because aggregate protocol TVL remains about $30.0M and usable depth is smaller than TVL. The individual review will not open until TVL is reproducibly above the size floor for 30 consecutive days. It must then cover the exact PT, YT or LP position, underlying issuer and venue, contracts and governance, audits and incidents, negative-yield history, maturity terms, secondary depth, stressed exit and named alternatives. Separate AMM-LP or leverage rules still apply when those mechanisms are present.
Research status
This is a capacity-unproven record for Spectra V2, not a quality rejection or approval. Reported TVL says how big the venue is, not what the client owns, who can change the rules, or how a position exits at a proposed size. The individual review opens when the protocol clears the size floor.
Sources
The claims above trace to these. Where a number could not be independently verified, the thesis says so.

Inherited controls
The research above describes the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The layer with the most administrative power sets the position’s effective control; that describes control, not quality or suitability.
| Chain | Verdict | Control | Control constraint |
|---|---|---|---|
| Flare | Approved with limits | Governed, no freeze | consensus entry is permissionless, but the Foundation monopolizes governance proposals and manually executes some approved changes. |
| Avalanche | Approved with limits | Governed, no freeze | no party can freeze or seize C-Chain funds, but one vendor writes the only production client and Messari measured over a third of stake hosted on AWS. |
| Ethereum | Approved | No freeze key | No sequencer, no upgrade key, no operator who can be compelled. Rule changes require social consensus. |
| Base | Approved with limits | Mixed control | Coinbase, one regulated US company, operates the only sequencer, and admin keys can upgrade bridge contracts within ~7 days. |
| Hyperliquid / HyperEVM | Rejected | Issuer can freeze | a 21-validator permissioned set operates both the chain and its bridge. One compromise reaches both. |
| OP Mainnet | Rejected | Mixed control | Ethereum forced inclusion limits sequencer censorship, but the Foundation and Security Council can co-sign an immediate upgrade before a client can exit. |
| Arbitrum One | Approved with limits | Mixed control | a single sequencer orders >99% of transactions and admin keys can upgrade bridge contracts on a ~7-day timelock. |
| Monad | Approved with limits | Governed, no freeze | the L1 has a public validator path, but its short production record, single initial client lineage, and Foundation-directed delegation keep stake and operations concentrated. |
