Yoroi Wallet is an open-source Cardano and Ergo wallet developed and maintained by Emergo, one of the founding entities of Cardano. Yoroi is good for sending and receiving ADA, voting on Project Catalyst proposals, and managing your stakepool delegation. Yoroi is classified as a light wallet because it doesn’t run the entire blockchain in your browser or mobile device, but instead connects to Emergo servers remotely to read and post transactions to the Cardano network.
