Reputation Score

Quickly assess researcher submissions with a reputation score that reflects their proven track record, making it easier to manage findings and ignore spam, especially during bug bounties.

Pings

Pings reduce the opportunity for spam by limiting the number of @project tags a researcher has during an engagement based on their reputation level.

@project another concern related to supplyBalance.

Do we want the market value to exceed the cap? Assume a market is set at cap 10M and the vault owns 15M liquidity of the market. Do we want the value of the market to be capped at 10M? To reflect the full amount of the liquidity is more intuitive but riskier.

Assuming the vault wants to allocate 10% liquidity to a riskier market (e.g. DAI-Doge), in the event that Doge's price crashes, the Vault could potentially lose more than 10% of its liquidity.

Moreover, considering the morpho-blue protocol's removal of bad-debt socialization, we should discuss how the vault manager should handle situations in which a market have bad-debt but keep pumping vault's value

During enable mode, two validators are used.

1. validator: The module to be installed as any module type that can be defined. It must be     a validator either already before the user op or after enabling it as a validator in enable     mode. This validator will be used to validate the final userOp.
2. enableModeSigValidator: This validator is used in _checkEnableModeSignature to check     the _getEnableModeDataHash(validator, initData) for enabling the first validator.Note that these two validators are independent of each other and might have different trust assumptions and privileges.
While a user operation has a nonce field (that is used in the userOpHash and its signature) and the entrypoint checks and increments this nonce to avoid replaying a user operation, the inner enableModeSignature does not have any such replay protection. The same module, moduleInitData, enableModeSignature can be used in a different user operation to install the module a second time, for example, after the user uninstalled the module already.As the entire enable mode data is encoded in the userOp.signature that is not part of userOpHash, a bundler can replace the enable mode data with a different previously signed one without invalidating the user operation (as long as the enable mode bit and the validator encoded in the userOp.nonce match).
