Rainbow is a beautifully designed self-custodial wallet focused on Ethereum and Layer 2s. Here's the exact path from Rainbow to a funded GetPlu Visa - networks, fees, troubleshooting, and what you can do once your balance lands.
Funding Checklist
- Open GetPlu, select Rainbow as your funding source, and confirm the network the deposit screen lists before sending.
- In Dominican Republic, always follow the latest funding labels inside the GetPlu app before you move stablecoins.
- After the on-chain transfer confirms, your GetPlu Visa balance updates; spend online or in-store anywhere Visa is accepted.
Why fund GetPlu from Rainbow?
Rainbow is a beautifully designed self-custodial wallet focused on Ethereum and Layer 2s.
GetPlu issues a Visa card you can fund directly with stablecoins. Rainbow is EVM-only with strong Ethereum mainnet and L2 support (Arbitrum, Optimism, Base, Polygon, zkSync). For GetPlu funding, send via Base (recommended - lower fees) or Ethereum mainnet (ERC-20). The result: one on-chain transaction, then you spend at any of 100+ million Visa merchants in 125+ countries - no exchange off-ramp, no bank account required.
This guide walks you through the exact flow: copying GetPlu's deposit address, choosing the right network on Rainbow, sending the transfer, and confirming the credit. Most users finish in under 5 minutes.
What you'll need
- Rainbow installed on your mobile app or browser extension
- USDC or USDT on Base (recommended) or Ethereum (ERC-20) balance in your Rainbow wallet (enough for the transfer + a small network fee buffer)
- A GetPlu account (free - sign up at app.getplu.com if you don't have one)
- Internet connection on both devices
Step-by-step
1. Open GetPlu and tap Add funds
Choose USDC or USDT. GetPlu will prompt you to pick a network.
2. Choose your network
Rainbow sends via Base (recommended - lower fees, faster confirmations) or Ethereum (ERC-20, also available). Both are EVM-compatible, so GetPlu's wallet works with either.
3. Copy the deposit address
GetPlu 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 Rainbow and tap Send
In Rainbow, tap your USDC or USDT balance, then Send. Make sure 'Base' or 'Ethereum' is selected - Rainbow defaults to whatever network you used last. Paste the GetPlu deposit address.
5. Paste the address and enter the amount
Paste the GetPlu deposit address. Enter the USDC or USDT amount you want to fund. Rainbow will show you the network fee - review it, then confirm.
6. Wait for the credit
Once the transaction confirms on-chain, GetPlu credits your balance. Base typically takes Under 30 seconds. You'll see a notification in the GetPlu app.
Network selection
Rainbow supports the following networks for GetPlu funding:
| Network | Fee | Speed | Recommended for |
|---|---|---|---|
| Base | Under $0.10 typical | Under 30 seconds | Recommended - lowest fees, fastest confirmations |
| Ethereum (ERC-20) | $2-15 typical (gas-dependent) | 1-3 minutes | Also available |
Default recommendation: **Base**.
Common issues and fixes
- Wrong network - Rainbow's network switcher is at the top. Make sure it matches Base or Ethereum, whichever GetPlu shows for your deposit - other L2s (Arbitrum, Optimism, Polygon) won't credit.
- Gas token - Base gas is a small amount of bridged ETH (a few cents); Ethereum mainnet gas is paid in ETH directly and costs more.
- Rainbow Defaults - Rainbow has a feature called 'Bridge before send' for cross-chain. Don't enable this for GetPlu transfers unless you're deliberately bridging from an unsupported network.
- Token contracts - Rainbow shows token logos clearly, but verify the contract address matches official USDC/USDT on the network you selected before first-time sends.
What you can do once funded
Once your GetPlu balance lands, you can:
- Add the GetPlu 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
Browse the dedicated USDC and USDT card pages to see networks supported, country availability, and detailed comparisons.
Frequently asked questions
Can I send via Optimism or Arbitrum from Rainbow?
No - GetPlu accepts Base or Ethereum mainnet deposits only, not other L2s. If your USDC/USDT is on Optimism or Arbitrum, bridge to Base first using the official bridge or a fast service like Across.
What network should I use to send from Rainbow?
Base is recommended - lower fees and faster confirmations than Ethereum. Ethereum (ERC-20) is also available if that's where your balance already sits.
How long does the transfer take to credit my GetPlu balance?
Once the transaction confirms on-chain, GetPlu credits your balance immediately. Base confirmations typically take under 30 seconds; Ethereum (ERC-20) takes 1-3 minutes.
