Expanding digital realms will be created at the intersection of scalable blockchain technology and captivating Web3 culture.
NFTs, identity and ownership open a new and exciting exploration space.

We have released a new Elrond Explorer upgrade, which brings enhanced transparency and several key growth metrics about the ecosystem, such as market data for ESDT tokens, logs for specific failed SC calls, badge identifiers for full history nodes & locked accounts, and more.
The already proven smart contract-based Price Discovery mechanism was once again in the spotlight, managing 17M+ $CRT and 94K+ $EGLD in deposits, totaling $11M+ USD.
The result was a seamless process that ensured minimum volatility and maximum fairness to everyone involved.
The upcoming Elrond NFT marketplace components have undergone a series of enhancements, such as caching optimizations on the NFT service, multiple elastic updates and improvements on the rarity service. Implemented data loaders in order to facilitate batch retrieval.
