Linkdrops allow users to distribute assets and onboard people to Web3 apps through a simple web link. Linkdrop They work by storing assets and linking AccessKeys to them. The AccessKeys are then distributed to users in the form of web links. These links take users to a website that automatically uses the keys to call the claim method in the linkdrop contract. In order for a contract to be considered a Linkdrop-contract it has to follow the NEP-452 standard. The NEP-452 explains the minimum interface required to be implemented, as well as the expected functionality.

​
NEP-452 (Linkdrop Standard)

NEP-452 is the blueprint for all linkdrop contracts on NEAR. It defines a common set of rules and functions that the contract MUST implement to be considered a linkdrop contract.
Notice that the NEP-452 defines the interface and expected behavior of a linkdrop contract, but it does not dictate how the internal logic should be implementedDifferent linkdrop contracts can have different internal implementations while still adhering to the NEP-452 standard

​
Interface

​
get_key_balance (read-only)

Allows to query the amount of NEAR tokens assigned to a specific linkdrop key 
get_key_balance(key: string): string;

​
get_key_information (read-only)

Returns information about a specific linkdrop key, including the amount of NEAR tokens assigned to it, the receiver ID, and whether the key has been claimed 
interface NFTData {
  contract_id: string;
  token_id: string;
}

interface FTData {
  contract_id: string;
  amount: string;
}

get_key_information(key: string): { required_gas: string, yoctonear: string, nft_list: NFTData[], ft_list: FTData[] };

​
claim

Allows a user to claim the assets associated with a specific key. The function transfers the NEAR tokens, NFTs, and FTs assigned to the provided account_id, which MUST exist prior to calling this method.
⚠️ Users need to call this method signing the transaction with the linkdrop key they received. 
claim(account_id: string): boolean;

​
create_account_and_claim

Allows a user to create a new account and claim the assets associated with a specific key. The function creates the new account with the provided new_account_id and transfers the NEAR tokens, NFTs, and FTs assigned to it.
⚠️ Users need to call this method signing the transaction with the linkdrop key they received. 
create_account_and_claim(new_account_id: string, new_public_key: string): Promise<boolean>;
