If I transfer my iotx-E tokens from ledger nano to iotex eth contract address on metamask, when token swap is completed, how will I receive my iotx native tokens?
do you mean you staked IOTX-E with staking contract?
Staking and vote for delegate, it will auto swap to native token for you . no need to do anything
