How long does a USDT payment to MEV Boost Relay usually take?

TRC20 payments confirm in 3–5 minutes; ERC20 can take 10–30 minutes depending on gas.

What if I sent USDT without a memo?

Contact support with your TXID – they can manually attribute the funds if the memo is missing.

Can I cancel a pending payment?

If the transaction is still pending on chain (not confirmed), you can cancel it via your wallet and resend.

Why is my ERC20 USDT pending for hours?

Low gas fee is likely the cause. Resend with at least 30 Gwei or use TRC20 for faster confirmation.

Does MEV Boost Relay accept credit cards?

No, only USDT (TRC20/ERC20) – no KYC, no card needed, ensuring privacy and speed.

MEV Boost relay Payment Stuck or Pending — Troubleshooting

Why Your MEV Boost Relay Payment Is Stuck

If you're seeing "Payment Pending" on MEV Boost Relay after sending USDT, you're not alone. This usually happens due to network congestion, wrong memo/tag, or insufficient gas. Let's fix it.

Check the Transaction on Chain

First, verify your USDT transfer on Tronscan (TRC20) or Etherscan (ERC20). If the transaction is confirmed but the relay shows pending, the issue is on the relay side. Use your TXID and check if the recipient address matches exactly.

Common Causes & Fixes

### 1. Missing or Wrong Memo/Tag MEV Boost Relay requires a destination tag (memo) for TRC20 payments. Without it, funds get stuck. Resend with the correct memo provided in your dashboard.

### 2. Insufficient Network Fee (Gas) For ERC20 payments, low gas (e.g., < 20 Gwei) can delay confirmation. Use a gas tracker to set at least 30 Gwei for timely processing. TRC20 USDT typically costs ~0.8–1.5 USDT in fees.

### 3. Network Congestion Ethereum mempool can be clogged. If your ERC20 USDT is pending for >30 minutes, cancel and resend with higher gas. TRC20 usually confirms under 5 minutes.

### 4. Payment Not Matching Plan Price Ensure you sent exactly the required amount (e.g., 150 USDT for a 1-month MEV Boost subscription). Over/under payments trigger manual review delays.

Step-by-Step Troubleshooting

**Verify TX Status** – Go to Tronscan.org or Etherscan.io, paste TXID. If confirmed, proceed.
**Contact Support via Telegram** – Provide TXID and dashboard email. Expect response within 2–4 hours (2026 support SLA).
**Cancel and Retry** – If pending >1 hour, cancel the order (if allowed) and resend with correct memo and sufficient fee.

When to Wait vs. Act

TRC20 pending >10 mins → contact support.
ERC20 pending >1 hour → resend with higher gas.
Both: if payment shows "completed" on block explorer but relay says pending, it’s a sync issue – support can fix in minutes.

Pro Tip: Always Use TRC20 for Speed

TRC20 USDT is faster (3–5 min confirm) and cheaper (~1 USDT fee) than ERC20. We recommend TRC20 for all MEV Boost Relay payments to avoid gas-related delays.
