The assessments
what each score rests on- 018.9/10
Uniswap Protocol
Best for pool contracts with no admin key over funds, at the largest scale
Company file: Uniswap, owners, incidents →Strong◆ Sources checked · 27 Sept 2026The most consequential contract set in DeFi and among the most conservative. No admin key can move pooled funds, and the v2, v3 and v4 pools have held billions since 2020 without a protocol-layer exploit. Since the UNIfication vote of December 2025 a governance-set share of each pool fee goes to a UNI burn rather than to liquidity providers.

Strengths
- No admin key over pooled funds; old versions keep running unchanged
- No protocol-layer exploit on v2, v3 or v4 since 2020
- The protocol fee is set on-chain by a public vote and does not change the price a swapper pays
Against it
- Non-upgradeable contracts mean bugs cannot be patched either
- Since Dec 2025 LPs keep a smaller share of each fee; the rest funds a UNI burn
- A v4 pool is only as safe as its hook, and anyone can deploy one

Lido Protocol
Best for scale and integration, with the concentration question attached
Company file: Lido, owners, incidents →Strong◆ Sources checked · 27 Sept 2026Operationally excellent and structurally contentious. No stETH holder has lost principal to a protocol failure; the concern is the share of Ethereum validation it intermediates, still mostly through operators approved by LDO governance. A permissionless module capped at about 5% of stake and, since 30 Jun 2025, a stETH-holder brake on governance have narrowed that concern without removing it.

Strengths
- No loss of user funds at very large scale
- Deepest secondary liquidity of any staking receipt
- stETH holders can delay governance decisions they object to (Dual Governance, since Jun 2025)
Against it
- Intermediates about a fifth of staked ETH, a network-level concern
- Operator set still mostly curated; the permissionless module is capped at about 5% of stake
- V3 stVaults mean stETH now depends on more contracts than before 2026

MakerDAO / Sky
Best for the longest continuous operating record of any DeFi protocol
Company file: Sky, owners, incidents →Strong◆ Sources checked · 27 Sept 2026The oldest significant protocol in DeFi and the one that has survived the most; it renamed itself Sky in August 2024. Black Thursday in March 2020 produced real bad debt, which was recapitalised through a public MKR auction — a stress test nothing else in this table has undergone at that severity. Vault owners who lost collateral in zero-bid auctions were not compensated.

Strengths
- The longest continuous operating record in DeFi, across every cycle
- Recapitalised in public after Black Thursday rather than socialising the loss to DAI holders
- Governance process has functioned under genuine stress
Against it
- Governance holds wide authority over collateral and parameters, and SKY voting is concentrated
- Real-world asset exposure adds counterparties that cannot be verified on-chain
- The 2024 rebrand and Star structure have reduced clarity about the current model

Aave Protocol
Best for actively risk-managed lending, if you check which collateral others may post
Company file: Aave, owners, incidents →Solid◆ Sources checked · 27 Sept 2026Upgradeable by design, which is a trade rather than a flaw: parameters can be tightened when a collateral type turns dangerous. April 2026 showed the other side. Unbacked rsETH, accepted at up to 95% loan-to-value, was used to borrow about $193M, and the gap was covered by liquidations and the DeFi United coalition rather than by suppliers.

Strengths
- Published risk framework and on-chain rate curves
- rsETH was frozen across all V3 markets within about 90 minutes of the exploit
- Losses so far were covered by liquidations, the DAO or a coalition rather than by suppliers
Against it
- Upgradeable contracts mean governance can change the rules after you deposit
- A single high-LTV collateral asset put about $193M of loans at risk in Apr 2026
- The rsETH coverage is documented in governance posts, not in an independent final accounting
Full assessment of Aave Protocol →solid · 7.9/10
The base layer everything else in DeFi is built on. What matters here is not the yield on the front page but whether the contracts can be changed, who can change them, and whether the thing has survived a market break rather than merely a quiet year. An upgrade key is a custody question wearing a technical costume, and we score it as one.
Frequently asked questions
Is an immutable protocol always better than an upgradeable one?+
No — it is a different bet. Immutable means nobody can change the rules after you deposit, and also that nobody can fix a bug. Upgradeable means parameters can be tightened when a collateral type turns dangerous, and also that whoever holds the key could do something else. What matters is that you know which bet you have taken.
Does an audit mean a protocol is safe?+
It means someone was paid to look. Most large exploits have hit audited code, often at the composition layer between contracts that each audited cleanly on their own. We weight audits inside custody, but a long record at scale under real conditions is worth more than another report.
Why does governance concentration matter if I am just depositing?+
Because on an upgradeable protocol, governance can change collateral parameters, fees and in some cases the contracts themselves — while your money is inside. Concentrated governance means a small group can make that decision. It is a custody question, and we score it as one.
