Fraxlend
Fraxlend, from the Frax team, lets anyone create an isolated lending market between any pair of ERC-20 tokens with a Chainlink price feed. It held $11.1 million across 34 pools on Ethereum and Fraxtal at the 2026-08-14 survey. The registry rejects it because it is below the size floor. One practice advising 100 households moves $1M to $8M into a venue on the same research, and that book could crowd the exit at this size. Size alone decides the result, whatever the protocol’s quality. Do not open an individual review until it clears the floor. Then focus on permissionless market creation: isolated pairs contain bad collateral, but each market still needs its own underwriting.

The research file
Applicability to the surveyed record
Fraxlend is an isolated-pair lending protocol. One ERC-20 asset is lent against a different ERC-20 collateral asset. Lenders receive redeemable fTokens, and each pair has its own oracle, rate, and maximum-LTV terms. Those facts place the surveyed Fraxlend record in lending, but this finding does not replace pair-level underwriting.
Current observation and perimeter
The DefiLlama API read on 2026-08-15 reported approximately $19.1M supplied and $6.13M borrowed across Ethereum, Arbitrum and Fraxtal. The observed supplied TVL remains well below the shared v1 size floor, so the individual review is not opened until it clears that floor.
Control and exit applicability
A pair’s asset, collateral, oracle, rate calculator, maximum LTV and immutable liquidation fee set the lender’s risk. fTokens are claims on that pair’s assets, so redemption depends on available unborrowed liquidity. Liquidation recovery and any bad debt stay with that pair rather than being spread across Fraxlend.
Why the class rule decides
The shared v1 size rule decides the result. Do not open the individual review until supplied TVL stays at or above the size floor for 30 days. Then review each candidate pair’s assets, oracle, deployer and administrative authority, utilization, caps, audits and incidents, liquidation and bad-debt history, stressed fToken redemption, and named lending alternatives.
Research status
This is a capacity-unproven record for Fraxlend, 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 |
|---|---|---|---|
| Ethereum | Approved | No freeze key | No sequencer, no upgrade key, no operator who can be compelled. Rule changes require social consensus. |
| 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. |
