Ethermint

Ethermint is a scalable and interoperable Ethereum library, built on Proof-of-Stake with fast finality using the Cosmos SDK which runs on top of Tendermint Core consensus engine. Evmos is a scalable and interoperable Ethereum blockchain, built on Proof-of-Stake with fast finality. For prerequisites and detailed build instructions please read the Evmos Installation instructions. In Ethereum, the personal API manages private keys in the keystore. We needed to implement this functionality on Ethermint so that Ethereum keys and signing would all be compatible. Since the Cosmos-SDK’s keyring doesn’t explicitly support locking and unlocking of keys the way Ethereum does, a workaround had to be implemented. Unlocking a key is done by exporting it from the Cosmos keyring via decrypting the file and storing it in memory. Locking the key deletes it from memory, leaving it only as an encrypted file on-disk.
