Pump.fun Dev Wallet vs Bundle Wallet: What's the Difference? (2026)

What is a Dev Wallet?

The dev wallet on Pump.fun is the wallet that creates the token. Its address appears on-chain as the token creator — visible to anyone who checks the token's on-chain data. The dev wallet signs the token creation transaction, pays the Pump.fun creation fee (approximately 0.02 SOL), and typically also makes the initial dev buy. Because the dev wallet address is publicly visible as the token creator, it should be a dedicated isolated address completely separate from your main identity wallet.

What is a Bundle Wallet?

Bundle wallets are dedicated keypairs configured to execute simultaneous buy transactions in block 0 alongside your token creation. They are not the token creator — they are buyers. In a Jito bundle, your dev wallet creates the token while 2-4 bundle wallets simultaneously purchase tokens at the bonding curve's initial price. Bundle wallets never appear as the token creator on-chain, giving them an additional layer of separation from the developer identity.

Why You Need Both

Using only a dev wallet means you buy as the publicly visible creator — community members can track your exact holdings and selling activity. Using both dev and bundle wallets means your supply is distributed across multiple addresses, some of which are harder to attribute to the developer. Bundle wallets also allow you to capture more supply in block 0 than a single dev buy would, maximizing your position at the lowest possible price.

Security Considerations for Each

Dev wallet: should be a fresh address with no connection to your main Phantom wallet. Its address will be publicly visible forever as the token creator. Do not reuse dev wallets across multiple launches — create a new dev wallet for each token. Bundle wallets: should also be fresh addresses generated for each launch. After withdrawing SOL post-launch, retire these wallets permanently. SolBundler generates both types of wallets locally in your browser with zero server transmission.

Funding Each Wallet Type

Dev wallet needs: token creation fee (0.02 SOL) + dev buy amount (0.3-0.5 SOL) + Jito tip (0.003-0.01 SOL) + fee buffer (0.05 SOL). Total dev wallet: approximately 0.4-0.6 SOL. Bundle wallets need: buy amount (0.3-0.5 SOL each) + fee buffer (0.05 SOL each). Use SolBundler's Fund Wallets feature to distribute SOL to all bundle wallets simultaneously from your dev wallet.

Post-Launch Management

Track both dev wallet and bundle wallet positions in SolBundler Project Manager. The dev wallet buy is typically smaller and may be exited first to reduce creator wallet visibility. Bundle wallet positions represent your primary profit position — exit gradually using Smart Sell to avoid chart impact. Use Withdraw All to collect all SOL back to dev wallet after all positions are exited.

Frequently Asked Questions

Should my dev wallet buy the same amount as bundle wallets?

No. Dev wallet buys are typically smaller (0.2-0.4 SOL) since the dev address is publicly visible and larger buys attract community scrutiny. Bundle wallets can buy more aggressively (0.3-0.6 SOL each) since they are not immediately identified as developer wallets.

Can I use the same address for dev and bundle wallets?

No — the dev wallet creates the token and its address appears as creator on-chain. Bundle wallets are separate buyer addresses. Using the same address for both would mean buying as the publicly visible creator for all positions.

How many bundle wallets should I use?

The maximum in a single Jito bundle is 4 buy wallets (plus 1 creation transaction = 5 total). Use 3-4 bundle wallets for standard launches. Add snipe wallets via LBS mode for additional supply capture in blocks 1-3.
