Maybe I missed it, but can't seem to find it anywhere. Is the unit used in Gwei or in Eth?

For example when writing :

stateDb, err := state.New(rootHash, db)
if err!=nil{
   return err
addressA := common.HexToAddress("0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B")

stateDb.SetBalance(addressA, big.NewInt(1000))

do we get 1000 eth or 1000 wei?

Any help appreciated

From state_object.go, the state code deals with the following account representation:

// Account is the Ethereum consensus representation of accounts.
// These objects are stored in the main account trie.
type Account struct {
    Nonce    uint64
    Balance  *big.Int
    Root     common.Hash // merkle root of the storage trie
    CodeHash []byte

setBalance() works on this representation of Balance.

The state representation in the code is a direct implementation of the specification in the Yellow Paper. The description of world state in section 4.1 of the Yellow Paper has this to say:

balance: A scalar value equal to the number of Wei owned by this address


It is impossible to answer without more information or code to see.

However, it is likely in wei. All values in Solidity are in wei, unless they are suffixed with a keyword such as ether, szabo, or finney.
