Did Malairte have a premine?

No. Malairte had no premine. No coins were created before the public could mine, and no large balances were credited to founder or team addresses in the genesis block. Every MLRT in existence traces back through an unbroken chain of mined blocks to a clean public genesis. You do not have to take this on faith. You can inspect the genesis block, read the early blocks, and reconcile circulating supply against the number of mined blocks to confirm it yourself. The verification how-to guides in this pillar walk through each step so the claim rests on the public record.
