Quick Start#

This guide shows how to interact with the LEA blockchain using the LEA Web3 SDK.

You will:

• connect to a LEA network,
• create a wallet,
• derive an account,
• query a balance,
• and submit a simple BasePOD transaction.

All steps use the BasePOD. No Custom POD configuration is required.

Install the SDK#

npm install @getlea/web3

Create a connection#

Create a connection to a LEA RPC endpoint.

import { Connection } from '@getlea/web3';
const connection = Connection('devnet');

You can also pass a full RPC URL instead of a network name.

Create a wallet#

Create a wallet from a BIP-39 mnemonic.

import { generateMnemonic, Wallet } from '@getlea/web3';

const mnemonic12 = await generateMnemonic();      // default 128-bit entropy
const wallet = await Wallet.fromMnemonic(mnemonic12);

The wallet manages keys and signing locally.

Derive an account#

Derive an account from the wallet.

const account = await wallet.getAccount(0);
console.log(account.address);

Query the balance#

import { basePodGetBalance } from '@getlea/web3';

const balance = await basePodGetBalance(connection, account.address);

console.log(balance);

Submit a transaction#

Submit a simple BasePOD transfer.

import { basePodTransfer } from '@getlea/web3';

const txId = await basePodTransfer(
  connection,
  account,
  'lea1destinationaddress',
  1_000n
);

console.log(txId);

The SDK automatically:

• publishes the account keyset if required,
• manages transaction chaining,
• submits the transaction,
• and decodes the execution result.

What happens next#

At this point, you have:

• a working LEA connection,
• a wallet and account,
• and the ability to interact with the BasePOD.

From here, you can:

• build application logic on top of BasePOD system programs,
• or explore additional BasePOD features as they become available.
