Our validator icon is a tribute to when we operated the lpSOL liquid staking token (details below).
Sign Labs runs on higher hardware specs than recommended by Solana Foundation, and we have one of the highest performing un-modded validators on the network in terms of vote credits. Sign Labs' validator also earned rewards 40% higher than the median over a 50 epoch sample size (slot 665 to slot 715). Details at Solana Compass
Critical Linux security patches are applied within 24 hours. Standard security updates are performed periodically to keep the node secure. Solana software gets updated on the Anza schedule, and in extremely rare scenarios, if there is risk of getting forked away from the primary chain.
SSH key authentication, firewalls and standard OS hardening are enabled on the validator. Only the node operator has SSH access to the validator. We run the Jito fork of Anza's validator software, combined with the new priority port from Palladin. No vote mods or custom transaction ordering, and no private order flow deals.
As a staker you maintain custody to your SOL and are free to unstake or redelegate at any time. We never have access to your funds. The validator is being constantly monitored to minimise delinquencies and to maximise staking APY. Validator funds are staked through a multisig wallet with a minimum of one hardware wallet signer.
This validator continues to host lpSOL in support of the LP Army, however the volume was not meaningful and the project was deprecated. The liquid staking token still exists, but since there is almost zero volume you will get better swap rates with a more liquid LST like vSOL.
lpSOL uses Sanctum's Infinity Pool for liquidity with minimal smart contract risk. When you buy lpSOL or create it by natively staking, the SOL gets delegated to the Sign Labs validator. Sign takes zero (0) commission fees and zero MEV from Jito tips, so stakers and lpSOL holders get all the rewards.
Sign Labs staff run the high performance validator, contributes regularly to the Solana Tech Discord, and also operate a Testnet node in order to contribute to Anza/Solana core development efforts. The lead administrator, Otto, is fully KYC'd by the Solana Foundation and can be reached on X @ autocatalytic.
Acknowledging our roots in Solana, the Sign Labs logo depicts an "S" in American Sign Language. We love signs, signals and Solana!
