According to news on March 10, Solana development tool provider Helius has launched Solana NFT Compression, developers can mint a large number of NFT at low cost through the Digital Asset Standard (DAS).
This is achieved by maintaining the NFT status outside the chain with index companies such as Helius instead of accounts, and a verification mechanism to ensure that the interaction between the chain and the program is legal and safe. As previously reported, on October 20, 2022, Helius completed a $3.1 million seed round of financing.
