Elowen Program

A Solana program (Anchor) with a TypeScript SDK. It covers token operations, presale, rewards, liquidity, and related utilities. The SDK wraps common interactions and helpers for clients and scripts.

Tech stack

• Rust + Anchor for on-chain program (programs/elowen)
• TypeScript SDK under app/ bundled via esbuild
• Tests and scripts using ts-mocha and Anchor scripts

Program IDs

• Devnet: 48ug74S2RBzih8DtNpyDqhTCZnzUoYuYyzwttmHEiMRS (matches Anchor.toml and declare_id!)

Prerequisites

• Node.js 18+ and Yarn
• Rust toolchain
• Solana CLI
• Anchor CLI 0.31.x

Install

yarn install

Build

• Build TypeScript SDK:

yarn build

• Build the Solana program:

# Devnet (enables devnet feature flags)
yarn build-devnet

# Mainnet-compatible build
yarn build-mainnet

Deploy

# Configure cluster
yarn set-devnet

# Deploy to devnet
yarn deploy-devnet

# Deploy to mainnet (requires proper config and keys)
yarn deploy-mainnet

Using the SDK

The package exports both Node and Browser builds.

import { Connection, clusterApiUrl } from '@solana/web3.js'
import { Wallet } from '@coral-xyz/anchor'
import ElowenProgram, { initializeProgram, getUserSolBalance } from '@elowen-ai/program'

const connection = new Connection(clusterApiUrl('devnet'), 'confirmed')
const wallet: Wallet = /* your Anchor-compatible wallet */

initializeProgram(connection, wallet, 'devnet')

const sol = await getUserSolBalance(wallet.publicKey)
console.log(sol.amount, sol.amountFormatted)

Key entry points:

• initializeProgram(connection, wallet, cluster)
• Static accessors on ElowenProgram: connection, provider, methods, accounts, ID
• Helpers like getUserSolBalance, getUserUsdcBalance, getUserElwBalance

Scripts and tests

Common scripts are defined in Anchor.toml and package.json. Examples:

# Type checking
yarn typecheck

# Prettier check / fix
yarn lint
yarn lint:fix

# Example Anchor/ts-mocha flows (see Anchor.toml [scripts])
anchor run initialize-elw
anchor run liquidity-initialize
anchor run presale-buy

Project structure

• programs/elowen: Anchor program (Rust)
• app/: TypeScript SDK and utilities
• tests/: TS-based tests and examples referenced by Anchor.toml
• esbuild.ts: SDK bundling to dist/esm and dist/cjs
• Anchor.toml: Anchor config, program id, scripts, provider
