Here's an example command for purchasing some ERC1155 NFTs using Flashbots:
cargo run buy \
--nft.erc1155 \
--nft.address "0xTheNFTAddress" \
--nft.ids 1 --nft.ids 2 --nft.ids 3 \
--eth.private_key "0xMyPrivateKey" \
--eth.url http://localhost:8545 \
--flashbots.bribe 1000000000000000000 \
--flashbots.bribe_receiver 0xYourBriberContract
Instead of providing nft.ids
, you can also provide a CSV file via the --nft.ids_path
command,
where the first column contains the id
of the NFT and the second column contains
the quantity
of purchased NFT.
Here's an ERC1155 example (which also requires passing the --nft.erc1155
flag)
1,1
2,5
3,2
And an ERC721 example

Flashbots Support: This will proceed to create a Flashbots bundle with 4 transactions: 3 NFT take orders on OpenSea, and a 4th transaction which sends the bribe to the briber contract while also doing consistency checks that we have received the NFTs
Public Mempool: If you omit the Flashbots parameters, it'll proceed to submit the transactions normally via the public mempool.
We use the stable Rust toolchain. Install by running: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
