Function blockhash

  • blockhash(putativeBlockhash): Blockhash

  • Combines asserting that a string is a blockhash with coercing it to the Blockhash type. It's most useful with untrusted input.

    Parameters

    • putativeBlockhash: string

    Returns Blockhash

    Example

    import { blockhash } from '@solana/rpc-types';

    const { value: isValid } = await rpc.isBlockhashValid(blockhash(blockhashFromUserInput)).send();

    [!TIP] When starting from a known-good blockhash as a string, it's more efficient to typecast it rather than to use the blockhash helper, because the helper unconditionally performs validation on its input.

    import { Blockhash } from '@solana/rpc-types';

    const blockhash = 'ABmPH5KDXX99u6woqFS5vfBGSNyKG42SzpvBMWWqAy48' as Blockhash;
