Nostra Finance, Starknet's eco-DeFi protocol, has launched a governance proposal to destroy NSTR tokens that were awarded to early investors and users during the TGE period but were not claimed. As of now, 21 million NSTR tokens (about $1.50 million) remain unclaimed. The deadline for claiming is set for December 17, after which the remaining unclaimed tokens will be gradually destroyed over a period of 6 months.
