on eth, is it possible to send multiple nfts in 1 tx? or is it cheaper to make a bundle on opensea, than xfer multiple from wallet to wallet.

it all depend on your mode of sending, 1155 has batch transfer, you can also use an external contract to do multiple transfer if approved.

how do u mean mode?

im actually just looking to transfer 3nft (or could be more) to another wallet for the cheapest fee

can you share the NFT contract address ?
otherwise there is a function that you can call if the NFT is built with EIP1155 standard called batchTransfer.

can u dm

u mean for checking if its eip1155?

yea if it is then you can do multi transfer the gas you pay doing that is promised to be cheap

but can u do that from wallet or need SC?

i don't think there is wallet that support that currently.
