What is Marinade?
Marinade is a stake automation platform that monitors all Solana validators and delegates to 100+ of the best-performing ones. Optimize your SOL staking rewards by using Marinade's automated strategy designed by the core team. Users of Marinade can choose between staking natively or liquid stake SOL for mSOL, a liquid staking token. Either option stakes your SOL with the same set of high-performance validators.
Eligibility criteria to receive stake from Marinade
For the Stake Auction Marketplace:
Validator is not blacklisted (running harmful mods, commission rugs)
Validator runs a version of the node that is in the specified semver bounds.
Validator's final inflation commission is ≤ 7 % (bids and MEV commission can be used to offset a higher public commission.)
Validator's uptime was> 80% in each of the last 3 epochs, calculated using the stake-weighted average of vote credits.
Validator has created and funded its PSR bond. The PSR bond must contain enough SOL for:
One epoch of downtime (1 SOL per 10k SOL)
One epoch of "Maximum_yield" for the epoch for the amount of stake received (set by the validator)
One epoch of bids (set by the validator)
This calculator can be used to estimate the bond size required for a given amount of stake.
For MNDE votes:
All the constraints above apply, with those slight differences:
The "max_bid" is not taken into account in the effective commission of the validator
Bids are not charged for the stake distributed through MNDE, but a PSR bond protecting the downtime and the yield for that stake still needs to be in place.
Blacklist
Marinade will blacklist validators that are identified as harming the network. A validator can get blacklisted for:
Slow voting (also called vote lagging) (SLOW_VOTER)
Commission rugs (COMISSION_RUG)
Failing to restart the node in the 36 hours following the cluster restart after a halt for at least 2 times
To be removed from the blacklist, the process is the following:
If a validator is blacklisted by Marinade's unjustly (e.g. validator's poor networking performance made us believe the validator was vote-lagging), the validator will be removed from the blacklist upon reviewing and approving the claim
If a validator, once rightfully blacklisted, chooses to reform their behavior and demonstrate compliance, they will be removed from the blacklist only after an observation period of at least 1 month.
Repeat offenders will be permanently blacklisted and prohibited from receiving Marinade stake. Rule 2 does not apply.
Validators blacklisted for commission rugs are blacklisted permanently. Rule 2 does not apply.
