Shimmer is a multichain, scalable network to build, connect, and secure sovereign Blockchain networks, enabling the frictionless transfer of assets and data across networks. The foundation of Shimmer is the parallelized UTXO-based DAG ledger. This allows anyone to mint and transfer native assets feelessly under a storage deposit model. On top of the DAG is a flexible application layer offering full EVM-compatibility and WASM support. Additionally, Shimmer will act as a staging network for upgrades to the IOTA ledger.
