Why fund Plu from Backpack?
Backpack is a Solana-first wallet with EVM support, popular among Solana DeFi and NFT users.
Plu issues a Visa card you can fund directly with stablecoins. Backpack is built around Solana but also supports Ethereum and other EVM chains. For Plu funding from Backpack, use the Ethereum side (ERC-20) directly, or bridge from Solana to Ethereum first. The result: one on-chain transaction, then you spend at any of 100+ million Visa merchants in 143+ countries — no exchange off-ramp, no bank account required.
This guide walks you through the exact flow: copying Plu's deposit address, choosing the right network on Backpack, sending the transfer, and confirming the credit. Most users finish in under 5 minutes.
What you'll need
- Backpack installed on your browser extension or mobile app
- USDC on Solana (with bridging to Ethereum or Tron) balance in your Backpack wallet (enough for the transfer + a small network fee buffer)
- A Plu account (free — sign up at app.getplu.com if you don't have one)
- Internet connection on both devices
Step-by-step
1. Open Plu and tap Add funds
Choose USDC or USDT. Plu will prompt you to pick a network.
2. Choose your network
Backpack is built around Solana. While Plu's primary supported networks are Ethereum and Tron, you'll want to bridge USDC from Solana to Ethereum first using a service like Wormhole or deBridge before funding. We recommend Tron-native wallets if you regularly fund from stablecoins.
3. Copy the deposit address
Plu shows a unique deposit address for the network you selected. Tap to copy. Verify the first and last 4 characters match what you'll paste in the next step.
4. Open Backpack and tap Send
In Backpack, switch to the Ethereum tab, tap USDC, then Send. Paste the Plu deposit address. Backpack will show the gas estimate in ETH.
5. Paste the address and enter the amount
Paste the Plu deposit address. Enter the USDC or USDT amount you want to fund. Backpack will show you the network fee — review it, then confirm.
6. Wait for the credit
Once the transaction confirms on-chain, Plu credits your balance. Ethereum (ERC-20) typically takes 1-3 minutes. You'll see a notification in the Plu app.
Network selection
Backpack supports the following networks for Plu funding:
| Network | Fee | Speed | Recommended for |
|---|---|---|---|
| Ethereum (ERC-20) | $2-15 typical (gas-dependent) | 1-3 minutes | USDC/USDT already on Ethereum |
| Solana | Under $0.01 | Under 30 seconds | Solana-native users (bridge first) |
Default recommendation: **Ethereum (ERC-20)**.
Common issues and fixes
- Solana vs Ethereum tabs — Backpack has separate views per chain. Plu accepts Ethereum (ERC-20), not Solana — use the Ethereum tab.
- Bridging from Solana — if your USDC is on Solana (most common in Backpack), bridge to Ethereum via Wormhole or deBridge. This adds a step and a small bridging fee.
- Gas in ETH — Ethereum side requires ETH for gas (same as MetaMask).
- xNFTs — Backpack's distinctive feature is xNFTs (executable NFTs). They don't affect Plu funding, but verify your token balances are visible in the standard Tokens tab before sending.
What you can do once funded
Once your Plu balance lands, you can:
- Add the Plu Visa to Apple Pay or Google Pay for contactless payments
- Pay any subscription billed in USD (Netflix, Spotify, GitHub, ChatGPT, AWS, etc.)
- Spend at any merchant accepting Visa — 100+ million worldwide
- Withdraw cash at ATMs at competitive rates
- Issue scoped Agent Cards for AI agents (Claude, Cursor, etc.) with hard spending limits

Frequently asked questions
Can I send Solana USDC directly to Plu from Backpack?
Plu doesn't accept Solana deposits at this time — only Ethereum and Tron. If your USDC is on Solana in Backpack, bridge to Ethereum using Wormhole or deBridge first, then send the Ethereum-USDC to Plu.
What network should I use to send from Backpack?
Backpack works best with Solana, but Plu's primary funding networks are Ethereum and Tron. Bridge your USDC from Solana to Ethereum first using Wormhole or deBridge.
How long does the transfer take to credit my Plu balance?
Once the transaction confirms on-chain, Plu credits your balance immediately. Confirmation time depends on the network: TRC-20 lands in 30-90 seconds, ERC-20 takes 1-3 minutes, Solana under 30 seconds.
What if I send to the wrong network?
Cross-chain mistakes are usually unrecoverable. Always confirm the destination address matches the network shown in Plu's deposit screen. Tron addresses start with "T", Ethereum addresses start with "0x", Solana addresses use base58 encoding. Backpack should clearly show the network at the top of the send screen — match it to what Plu requested.
Is there a minimum or maximum deposit?
Plu's minimum deposit is generally low (under $10 equivalent) but varies by tier. Maximum deposits scale with your account verification level. Network fees may make very small deposits uneconomical — it's best to batch top-ups when possible.
