Rust client to Opensea's APIs and Ethereum smart contracts

opensea.rs

Rust bindings & CLI to the Opensea API and Contracts

CLI Usage

Run cargo r -- --help to get the top level help menu:

opensea-cli 0.1.0
Choose what NFT subcommand you want to execute

USAGE:
    opensea-cli <SUBCOMMAND>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

SUBCOMMANDS:
    buy       Purchase 1 or more NFTs, with optional Flashbots support
    deploy    Deploy the Ethereum contract for doing consistency checks inside a Flashbots bundle
    help      Prints this message or the help of the given subcommand(s)
    prices    Get OpenSea orderbook information about the token

To view each individual subcommand's help menu, run: opensea-cli <subcommand name> --help

Buying NFT(s)

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

1
2
3

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.

Running ignored tests

1. Create a hardhat.config.js file and fork from mainnet at this block:

export default {
  networks: {
    hardhat: {
      forking: {
        url: "https://eth-mainnet.alchemyapi.io/v2/<YOUR API KEY>",
        blockNumber: 13037331,
      },
      hardfork: "london",
    }
  }
}

2. cargo test --ignored
