NEST, Lido's automated, rule-based LDO buyback mechanism, is live on mainnet after the Aug 5–8 on-chain vote. Under the LDO Accumulation Program, 2,320 stETH have been deployed, returning 14.8M LDO to the treasury, and outstanding LDO supply is down 1.8% to 879M. The mechanism links protocol performance to LDO via rules approved in a May Snapshot vote, funding regular buybacks from protocol revenue.
