Initialize Push Chain SDK

js

const privateKey = generatePrivateKey(); // Replace it with your private key generation logic
const account = privateKeyToAccount(privateKey);


const universalSigner = createUniversalSigner({
  address: account.address, // Ethereum address derived from the private key
  chain: CONSTANTS.CHAIN.ETHEREUM,
  chainId: CONSTANTS.CHAIN_ID.ETHEREUM.SEPOLIA,
  signMessage: async (data) => {
    const signature = await account.signMessage({
      message: { raw: data }, // Data to be signed
    });
    return hexToBytes(signature); // Convert signature to a byte array
  },
});

const pushChain = await PushChain.initialize(universalSigner);

react

const privateKey = generatePrivateKey(); // Replace it with your private key generation logic
const account = privateKeyToAccount(privateKey);

// Create Signer. Defaults to Ethereum Sepolia
const signer = createUniversalSigner({
  address: account.address,
  signMessage: async (data) =>
    hexToBytes(await account.signMessage({ message: { raw: data } })),
});

const pushChain = await PushChain.initialize(signer);

reactnative

const privateKey = generatePrivateKey(); // Replace it with your private key generation logic
const account = privateKeyToAccount(privateKey);

// Create Signer. Defaults to Ethereum Sepolia
const signer = createUniversalSigner({
  address: account.address,
  signMessage: async (data) =>
    hexToBytes(await account.signMessage({ message: { raw: data } })),
});

const pushChain = await PushChain.initialize(signer);

Send Transaction

js

// Send transaction
const tx = await pushChain.tx.send(
  // We will send the transaction to a Solana address
  [
    createUniversalAccount({
      chain: CONSTANTS.CHAIN.SOLANA,
      chainId: CONSTANTS.CHAIN_ID.SOLANA.DEVNET,
      address: 'ySYrGNLLJSK9hvGGpoxg8TzWfRe8ftBtDSMECtx2eJR',
    }),
  ],
  {
    category: 'MY_CUSTOM_CATEGORY', // Specify the category of the transaction
    // Sample email payload
    data: JSON.stringify({
      title: 'Hello old friend from Solana!',
      message: 'Greetings from Ethereum world.',
    }),
  }
);

react

// Send transaction
const tx = await pushChain.tx.send(
  // We will send the transaction to a Solana address
  [
    createUniversalAccount({
      chain: CONSTANTS.CHAIN.SOLANA,
      chainId: CONSTANTS.CHAIN_ID.SOLANA.DEVNET,
      address: 'ySYrGNLLJSK9hvGGpoxg8TzWfRe8ftBtDSMECtx2eJR',
    }),
  ],
  {
    category: 'MY_CUSTOM_CATEGORY', // Specify the category of the transaction
    // Sample email payload
    data: JSON.stringify({
      title: 'Hello old friend from Solana!',
      message: 'Greetings from Ethereum world.',
    }),
  }
);

      address: 'ySYrGNLLJSK9hvGGpoxg8TzWfRe8ftBtDSMECtx2eJR',
    }),
  ],
  {
    category: 'MY_CUSTOM_CATEGORY', // Specify the category of the transaction
    // Sample email payload
    data: JSON.stringify({
      title: 'Hello old friend from Solana!',
      message: 'Greetings from Ethereum world.',
    }),
  }
);

Fetch Transactions

js

// Fetch the latest 5 transactions
const results = await pushChain.tx.get('*', { limit: 5 });
for (const blocks of results.blocks) {
  for (const t of blocks.transactions) {
    console.log('transaction: ', t);
  }
}

react

// Fetch the latest 5 transactions
const results = await pushChain.tx.get('*', { limit: 5 });
for (const blocks of results.blocks) {
  for (const t of blocks.transactions) {
    console.log('transaction: ', t);
  }
}

reactnative

// Fetch the latest 5 transactions
const results = await pushChain.tx.get('*', { limit: 5 });
for (const blocks of results.blocks) {
  for (const t of blocks.transactions) {
    console.log('transaction: ', t);
  }
}
