What does this category cover?
This section holds decentralised-finance protocols that do not fit a narrower list — options and derivatives venues, on-chain insurance, real-world-asset credit, tokenised indexes and structured products. What they share is that each puts capital to work through smart contracts, and each can be judged on the same questions regardless of what it does: what it costs, what licence the code carries, who audited it, what backs it, and who controls it.
For anything holding value, what backs it?
The most important question for a protocol that holds or lends assets is what stands behind the tokens it issues. On-chain backing — collateral held in a contract whose value anyone can inspect live — is the strongest form, because it is directly verifiable rather than attested. Off-chain backing, such as real-world Treasuries or private credit, cannot be seen on-chain and depends on the quality and frequency of independent attestation. Neither is disqualifying, but the difference in verifiability is real, and a protocol that states which it is lets you weigh it.
Why the licence spans a wide range here
DeFi protocols run the full spectrum of licensing, from permissive open-source licences through delayed-open BUSL to bespoke non-commercial terms that forbid both commercial use and derivative works. Reading the actual licence file, rather than trusting an "open source" label, is how you tell what may genuinely be inspected and reused. For code that manages pooled capital, that distinction is a substantive one.
What to check
- Function and fees: a plainly explained purpose and a published fee schedule.
- Backing and transparency: what backs any issued token, and whether it is on-chain or attested.
- Audit disclosure: named, dated audit reports.
- Governance and control: who can change the protocol, and whether a timelock applies.
How we score this category
This category holds protocols that do not fit a narrower list — options venues, insurance, on-chain credit, tokenised indexes and real-world-asset platforms. The questions are the same whatever the protocol does: what it costs to use, what licence the code carries, who audited it, and — for anything holding or lending value — what backs it and whether that backing is published or merely asserted.
Every service in this ranking is scored 0–10 against the same 5 criteria, each carrying equal weight (20% apiece). The overall score is their plain average, rounded to one decimal place, and each review prints the individual numbers and the arithmetic so you can reproduce the result yourself.
What each criterion covers
- What it does & fees20% of the score
- Whether the protocol explains its function plainly and publishes its fees as figures. A named function and a stated fee schedule score above a vague description and an undisclosed cost.
- Licence & code openness20% of the score
- The licence on the protocol's own contracts repository, read from the file. A recognised open-source licence scores highest; a delayed-open or non-commercial licence mid-table; a missing file lowest.
- Audit disclosure20% of the score
- Whether audit reports are published with the firms named and dated. A protocol holding or lending value carries stacked risk, so a long list of named, dated audits matters here.
- Backing & transparency20% of the score
- For anything holding or lending assets, what backs it and whether that backing is published on-chain or attested. A stated, verifiable backing scores far above an unbacked claim or silence.
- Governance & control20% of the score
- Who controls the protocol, whether a timelock stands between a decision and its effect, and whether that is documented rather than left implicit.
