Integrating Particle Network for chain abstraction

Integrating Particle Network (chain abstraction)

We often face the task of building a universal dApp that works across multiple blockchains. Users want to interact with a protocol on Base while having funds on Ethereum. The standard approach — manual bridging — requires 3–5 transactions, up to 30 minutes waiting, and high gas costs. Particle Network solves this with Universal Accounts: one account, one balance, one signature for any chain. This is the next step after Account Abstraction — abstraction not only of the wallet but of the entire multi-chain environment.

Our experience shows: basic integration takes 2–3 weeks, and full integration with Universal Accounts takes up to 6 weeks. Below we break down the key components and the connection process.

What problems does chain abstraction solve?

Multi-transaction complexity. Users perform 3–5 operations instead of one: approve on Ethereum, bridge, approve on target chain, then the main transaction. Particle Network compresses this into a single operation, automatically selecting the optimal liquidity source. According to Particle Network documentation, Universal Accounts reduce transactions by 3–5 times, and gas savings can reach 60% — for active users, this means thousands of dollars per month.

Gas complexity. Each blockchain requires its own native token for fees. Universal Gas allows paying gas with any ERC-20 token (USDC, USDT, ETH) — conversion happens automatically.

Latency and liquidity. Users must wait for bridge transaction confirmations (up to 30 minutes) and monitor bridge liquidity. Particle Network uses a cross-chain layer that aggregates multiple bridges (Axelar, LayerZero, Wormhole) for instant operations. Recently we integrated Particle Network for a DeFi protocol on 5 chains: transaction time dropped 3x, and user churn due to complexity decreased by 40%.

How we implement integration: stack and configuration

Connect Kit — the entry point

import { ConnectButton, useAccount, usePublicClient } from "@particle-network/connectkit"; import { mainnet, base, polygon } from "@particle-network/connectkit/chains"; import { AuthType } from "@particle-network/auth-core"; // Provider setup export default function App() { return ( <ConnectKitProvider config={{ projectId: "YOUR_PROJECT_ID", clientKey: "YOUR_CLIENT_KEY", appId: "YOUR_APP_ID", chains: [mainnet, base, polygon], walletConnectors: [ evmWalletConnectors({ metadata: { name: "Your App" }, multiInjectedProviderDiscovery: true, }), authWalletConnectors({ authTypes: [AuthType.email, AuthType.google, AuthType.twitter], fiatCoin: "USD", promptSettingConfig: { promptMasterPasswordSettingWhenLogin: 1, }, }), ], plugins: { wallet: { visible: true, }, }, }} > <YourApp /> </ConnectKitProvider> ); } 

Universal Account for cross-chain operations

import { useUniversalAccount } from "@particle-network/universal-account-sdk"; function CrossChainButton() { const { smartAccount } = useUniversalAccount(); async function executeOnBase() { const transaction = { to: BASE_CONTRACT_ADDRESS, value: parseEther("0.1"), data: encodeFunctionData({ abi, functionName: "deposit" }), chainId: 8453, // Base }; // The system automatically: // 1. Checks user balances across all chains // 2. Selects optimal liquidity source // 3. Performs cross-chain operation if needed // 4. Executes transaction on Base const txHash = await smartAccount.sendTransaction(transaction, { feeQuotes: await smartAccount.getFeeQuotes(transaction), }); console.log(`Transaction: ${txHash}`); } return <button onClick={executeOnBase}>Execute on Base</button>; } 

Universal Gas in practice

const feeQuotes = await smartAccount.getFeeQuotes({ to: TARGET_CONTRACT, value: 0n, data: calldata, }); const usdcQuote = feeQuotes.find(q => q.tokenInfo.symbol === "USDC"); const txHash = await smartAccount.sendTransaction(tx, { feeQuote: usdcQuote, tokenPaymaster: usdcQuote.tokenPaymaster, }); 

Why choose Universal Accounts?

With Particle Network, transaction count is reduced by 3–5x compared to traditional bridges, and gas costs are cut by up to 60% thanks to payment in cheap stablecoins. This solution is 2x faster to integrate than alternatives. Users get a unified experience without knowing about internal bridges or tokens. For developers — one SDK and one integration for all chains.

Estimated timelines

Basic flow (social login + embedded wallet + gasless) — from 2 to 3 weeks. Adding Universal Accounts with cross-chain logic — another 1–2 weeks. Full customization with non-standard features — up to 6 weeks. Cost is calculated individually; we guarantee a fixed price after audit. Contact us for an accurate project estimate.

Step-by-step integration guide

1. Register your project in Particle Dashboard.
2. Install packages: npm install @particle-network/connectkit @particle-network/universal-account-sdk.
3. Configure the provider with your keys.
4. Implement social or email login.
5. Add getFeeQuotes call for gas payment with any token.
6. Use smartAccount.sendTransaction for cross-chain operations.
7. Test on testnet before mainnet deployment.
