Evmos is a cosmos chain that supports Ethereum transactions.
Cosmos transactions
Evmos has support for all the cosmos transactions: createValidator, stake, vote, send, ibcTransfers, … A normal user will probably just use:
MsgSend: It allows the user to send coins between wallets inside the chain.
Transfer: It is an IBC Transfer, that allows the user to send coins between different chains (it works like a bridge).
Delegate: It allows the user to freeze their coins and delegate them to a validator. Delegating coins will yield the user some profits.
WithdrawRewards: It allows the user to claim its staking rewards.
Vote: It allows the user to vote on governance proposals.
Ethereum transactions
Evmos supports EVM (Ethereum Virtual Machine) transactions, it exposes the same RESTApi as Ethereum to query the chain status and broadcast transactions.
Any valid Ethereum solidity contract can be deployed to Evmos without any change, and the way to interact with it it’s also the same.
