Connect to a Contract

Connect to a deployed smart contract to start interacting with it.

Usage

// Instantiate the SDK in either read or read-write mode
const sdk = new ThirdWebSDK("ethereum");

// Connect to your smart contract using the contract address.
const contract = await sdk.getContract("0x...");

Configuration

address (required)

The address of the smart contract you want to connect to.

const contract = await sdk.getContract(
  "0x...", // The address of your smart contract
);

Import Smart Contracts

If your smart contract was not deployed using thirdweb, you’ll need to import it on the dashboard.

contractType (optional)

If your contract is a prebuilt contract, it is strongly recommended that you provide the contract's name as the second argument to gain access to improved top-level functions and type inference.

Depending on the contract type you provide, the getContract method returns an instance of a different class with more specific methods available to use.

View available contract types

• NFT Drop: "nft-drop"
• Signature Drop: "signature-drop"
• Edition Drop: "edition-drop"
• NFT Collection: "nft-collection"
• Edition: "edition"
• Multiwrap: "multiwrap"
• Pack: "pack"
• Token Drop: "token-drop"
• Token: "token"
• Marketplace: "marketplace" | "marketplace-v3"
• Split: "split"
• Vote: "vote"

const contract = await sdk.getContract(
  "0x...", // The address of your smart contract
  "marketplace-v3", // The type of your smart contract
);

Using Contract ABI

Optionally, (if you don’t want to use the import feature), you can provide your smart contract’s ABI to the second parameter of the getContract method. Useful when developing on a local node, where it may be faster to use the ABI than to import the contract using the dashboard.

The ABI is only necessary if you have not deployed your contract with, or imported your contract to the thirdweb dashboard.

const contract = await sdk.getContract(
  "0x...", // The address of your smart contract
  abi, // The ABI of your smart contract
);
