Get Contract Value

Use Blocto wallet SDK to connect Solana

Note that Blocto SDK for Ethereum-like chains is still in Beta. APIs are subject to breaking changes.

Install from npm/yarn

$ yarn add @blocto/sdk @solana/web3.js @solana/buffer-layout

Use solana/web3.js api read from the contract

import BloctoSDK from "@blocto/sdk";
import { PublicKey } from "@solana/web3.js";
import * as BufferLayout from "@solana/buffer-layout";

const bloctoSDK = new BloctoSDK({
  solana: {
    net: "devnet",
  },
});

const formatProgramStruct = (data) => {
  const withBufferLayout = data.map((attribute) =>
    BufferLayout?.[attribute.type]?.(attribute.name)
  );
  return BufferLayout.struct(withBufferLayout);
};

const getContract = async () => {
  try {
    const key = new PublicKey(accountPubKey);
    // Different response type than the type of the response from getAccountInfo in @solana/web3.js
    const accountInfo = await bloctoSDK?.solana?.request({
      method: "getAccountInfo",
      params: [
        key,
        {
          encoding: "base64",
        },
      ],
    });

    if (!accountInfo) {
      setResponse("Error: Program not found.");
    }
    const layout = formatProgramStruct(JSON.parse(struct));
    const info = layout.decode(accountInfo?.data);
    setResponse(info);
  } catch (error) {
    console.error("error", error);
    setResponse(error);
  }
};
