💥Blast Network Guide

🚀 About the Blast Network

Blast is an Optimistic Rollup L2 built by the team behind Blur. It shifts the Layer 2 paradigm: assets are not only secure but also earn passive value. Blast is currently the only Ethereum L2 offering Native Yield for ETH and stablecoins.

• Mechanism: Blast deposits ETH into Lido and stablecoins (USDC/DAI) into MakerDAO.

• Auto-Rebase: The generated yield is automatically distributed back to every account on the chain.

• Result: This makes Blast the most capital-efficient Layer 2 in the ecosystem.

SlerfTools fully supports the Blast ecosystem, covering token minting, airdrops, trading, and wallet management.

📖 Network Setup & Tutorial Note

Use this page to find the Blast Network configuration parameters (RPC/Chain ID).

Note on Tutorials: Once you have switched networks, the operational workflow on Blast is identical to BSC. To avoid redundancy, our tutorials use BSC screenshots for demonstration.

• The interface and buttons on Blast are the same.

• Simply follow the visual guide, ensuring you are connected to the Blast network in your wallet.

🛠 Step 2: Core Operations Guide

SlerfTools offers deep compatibility with Blast's Yield Mode configuration, ensuring that your native yield is preserved and secure during all batch interactions.

Universal Operation Note (Must Read)

To streamline our documentation, the tutorials below may rely on BSC interface screenshots. The operational logic on Blast is 100% identical.

👉 You simply need to:

• Follow the Steps: Use the click-through patterns shown in the guide.

• Mental Swap: Treat any mention of "BNB" in the screenshots as "ETH" (your native gas token on Blast).

• Check Connection: Ensure your wallet is connected to Blast (Chain ID: 81457) before transacting.

🪙 Token Launchpad

Deploy Standard Token (Blast ERC-20)

• Deploy a standard, non-rebasing token. This format is ideal for most Memecoin projects that do not require complex yield mechanics.

• 👉 View Standard Token Tutorial

Vanity Contract Address

• Generate a unique, premium contract address (e.g., starting with specific characters) to make your token stand out in the crowded market.

⛽️ Gas Fees & Optimization (ETH)

Blast introduces a unique economic model for Gas, featuring Gas Revenue Claiming.

1. Cost Overview

• Standard Transactions: Paid in ETH. Costs are comparable to Optimism or Base—extremely affordable.

• Gas Revenue Sharing: A game-changer for developers. Smart contract deployers can claim a percentage of the Gas fees spent on their contracts. This acts as a massive native subsidy for the ecosystem.

2. How to Bridge Gas (ETH)?

• Official Blast Bridge:

  • Method: Deposit ETH from Ethereum Mainnet.

  • Note: Your deposited ETH begins earning Native Yield (approx. 4% APY) immediately upon arrival.

• Centralized Exchanges (CEX):

  • Major exchanges like Binance, OKX, and Bybit support direct deposits and withdrawals to the Blast network.

• Aggregators (Recommended for Stablecoins):

  • Tools: Orbiter or Owlto.

  • Feature: If you are bridging USDC from other chains, these bridges often automatically swap it into USDB (Blast's native rebasing stablecoin) upon arrival, saving you an extra transaction step.

3. Pro-Tips for Efficiency

• 💡 For Points Farmers: Manual transfers are not only time-consuming but can make tracking your "Yield Accumulation" messy. Using SlerfTools Batch Collection (Sweep) consolidates your funds in one go. This saves Gas and keeps your accounting clean for better Points tracking.

📊 Dev Resources (Common Assets)

⚠️ CRITICAL ALERT: Understanding Stablecoins on Blast Blast does NOT use standard USDC. It is replaced by USDB (Blast Native Stablecoin). When you bridge USDC to Blast, it automatically becomes USDB to enable the native yield generation.

• WETH (Wrapped Ether): 0x4300000000000000000000000000000000000004

(Note: Check the address format carefully! Unlike Mainnet WETH, Blast WETH supports Rebasing logic.)

• USDB (Native Stablecoin): 0x4300000000000000000000000000000000000003

(This is the functional equivalent of "USDC" on Blast. It comes with ~5% Native Yield automatically.)

❓ Blast Specific FAQ

Why is my ETH balance increasing automatically?

This is Blast's Native Yield mechanism at work. The Blast protocol stakes the underlying ETH into Lido, and immediately, automatically distributes the generated yield to all ETH-holding addresses. This happens at the protocol layer—no action is required on your part.

What is USDB? Why did my bridged USDC become USDB?

When you bridge USDC via the official bridge, it automatically converts to USDB. USDB is Blast's native stablecoin, backed by MakerDAO's on-chain T-Bill yield.

Holding USDB effectively means you are automatically earning US Treasury yields. In the Blast ecosystem, always use USDB for trading.

Do I need to handle "Rebase Logic" when deploying a token on Blast?

Recommended. If you deploy a standard ERC-20, it defaults to Void Mode (non-rebasing), meaning the generated yield goes to the Blast governance.

• If you want your token balances to grow automatically for users (Rebase), OR

• If you want to claim this yield revenue for your project treasury, You must configure the yield mode in your smart contract code.

Why is the WETH address 0x4300...?

Similar to Optimism, Blast uses special pre-deployed addresses. 0x4300...0004 is the Official WETH Contract.

Important: Always use this specific address. Do not use third-party wrapped ETH versions, or you may fail to accrue the automatic native yield.

Will batch transactions affect my "Blast Gold" earnings?

Usually, it helps. The Blast Points/Gold system evaluates not just capital size (TVL) but also interaction frequency and DApp activity. Using SlerfTools for high-frequency batch interactions with ecosystem contracts (like the Thruster Router) can help increase your on-chain activity weight.
