As blockchain crossed the chasm between early adoption, and mainstream use, it gradually became more obvious that its place would be to serve as the backbone for a new internet economy.
Elrond sits at the forefront of this remarkable revolution.

Significant changes to our API infrastructure that can now proactively refresh NFT media & metadata after processing. Extended connection support to light nodes for endpoints that do not need full history information.
A new tool that can generate a bulk of hierarchical deterministic keys from a mnemonic phrase is in development, together with an additional one that can automatically merge db level data from different sources.
We have expanded the documentation with guides on how to connect a dApp to WalletConnect & calculate the staking APR, along with a better structure for the main sections.
