Why fund Plu from Coinbase Wallet?
Coinbase Wallet is the self-custodial wallet from Coinbase — separate from the exchange, with EVM and Solana support.
Plu issues a Visa card you can fund directly with stablecoins. Coinbase Wallet supports Ethereum (ERC-20) and Solana directly. For sending USDC, ERC-20 is the cleanest path to Plu since both networks Plu supports (Ethereum and Tron) overlap with Coinbase Wallet's EVM coverage. 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 Coinbase Wallet, sending the transfer, and confirming the credit. Most users finish in under 5 minutes.
What you'll need
- Coinbase Wallet installed on your browser extension or mobile app
- USDC on Solana (with bridging to Ethereum or Tron) balance in your Coinbase Wallet 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
Coinbase Wallet 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 Coinbase Wallet and tap Send
Open Coinbase Wallet, tap Send. Choose USDC or USDT, then choose Ethereum as the network. Coinbase Wallet will prompt for a recipient — paste the Plu deposit address and enter the amount.
5. Paste the address and enter the amount
Paste the Plu deposit address. Enter the USDC or USDT amount you want to fund. Coinbase Wallet 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
Coinbase Wallet 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
- Coinbase Wallet ≠ Coinbase exchange — Coinbase Wallet is self-custodial; the exchange holds custody. Funds in your Coinbase exchange account need to be transferred to Coinbase Wallet first (or sent directly to Plu from the exchange's withdrawal flow).
- Network mismatch — make sure 'Ethereum' is selected, not Polygon or Base, when sending USDC. Plu credits Ethereum-network deposits, not L2 deposits.
- Insufficient ETH for gas — same as MetaMask. Keep $5-10 of ETH for gas.
- USDT not held by default — Coinbase Wallet emphasizes USDC. If you want to send USDT, make sure you have USDT (not USDC) selected before pasting the address.
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 from Coinbase exchange directly to Plu?
Yes — when withdrawing from the exchange, select 'External wallet', paste the Plu deposit address, and choose the network (Ethereum for ERC-20). The exchange handles the on-chain transfer. Note that exchange withdrawal limits and fees apply.
What network should I use to send from Coinbase Wallet?
Coinbase Wallet 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. Coinbase Wallet 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.
