Spectra V2
Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.
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 $100M materiality floor after higher-order exclusions. At this size an advised book could become a meaningful share of executable market liquidity. Reopen after sustained scale, then underwrite each PT, YT, or LP position and its underlying yield source separately; threshold passage would not imply approval.

The research file
Applicability to the surveyed record
Spectra V2 tokenizes an ERC-4626-compatible interest-bearing token into Principal Tokens representing principal and Yield Tokens representing future yield. Its permissionless markets support fixed-rate PT purchases, variable-yield or points exposure through YT, and PT/IBT liquidity positions. This establishes the current protocol identity without treating those economically different positions as one individually reviewed 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 remains less than one third of the shared v1 $100M threshold; the largest balances were on Hemi and Flare.
Control, loss and exit applicability
Anyone can create a market with a compatible interest-bearing token, target rate and maturity, so every position inherits the underlying token and protocol rather than 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 controls before product-level underwriting because aggregate protocol TVL remains about $30.0M and usable depth is smaller than TVL. Reopen after TVL is reproducibly at least $100M for 30 consecutive days, then review 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 where their mechanisms are present.

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

Inherited controls
The verdict above grades the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The least safe layer sets the position’s grade, and the position table names which one that is.
| Chain | Verdict | Grade | Control constraint |
|---|---|---|---|
| Flare | Approved · limits | crypto-backed | consensus entry is permissionless, but the Foundation monopolizes governance proposals and manually executes some approved changes. |
| Avalanche | Approved · limits | crypto-backed | 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 | sovereign | No sequencer, no upgrade key, no operator who can be compelled — rule changes require social consensus. |
| Base | Approved · limits | hybrid | Coinbase — one regulated US company — operates the only sequencer, and admin keys can upgrade bridge contracts within ~7 days. |
| Hyperliquid / HyperEVM | Rejected | freezable | a 21-validator permissioned set operates both the chain and its bridge — one compromise reaches both. |
| OP Mainnet | Rejected | hybrid | 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 · limits | hybrid | a single sequencer orders >99% of transactions and admin keys can upgrade bridge contracts on a ~7-day timelock. |
| Monad | Approved · limits | crypto-backed | 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. |
