Short answer: 10
For everyday use, most Monero wallets consider incoming funds fully unlocked after ~10 confirmations, which is about 20 minutes since Monero’s target block time is ~2 minutes per block.
Mined (coinbase) rewards require ~60 confirmations (~2 hours) before they’re spendable.
What a “Confirmation” Means in Monero
- When your transaction lands in a block, that’s 1 confirmation. Each block added after it increases the confirmation count.
- Because Monero’s target block time is ~2 minutes, confirmations accumulate quickly compared with chains that have longer block times.
Typical Confirmation Requirements by Scenario
- Coffee, small in-person buys: Many merchants accept 0–1 confirmation (risk-based choice for small tickets).
- Normal online purchases: Commonly 1–2 confirmations (~2–4 minutes) before fulfillment.
- Larger purchases / higher risk: 10 confirmations (~20 minutes) is a widely used safety threshold in wallets.
- Exchange deposits: Varies by exchange—often 10–20+. Always check the exchange’s current requirement.
- Mined (coinbase) rewards: 60 confirmations (~2 hours) before spendable.
Why Do Wallets Show “Pending” Until ~10 Confirmations?
- Reorg safety: Waiting ~10 blocks adds strong protection against short chain reorganizations.
- Good UX default: Wallets tend to strike a balance: fast availability for routine use while minimizing double-spend risk.
Monero Block Time & Confirmation Math
- Target block time: ~2 minutes
- 1 confirmation: ~2 minutes
- 3 confirmations: ~6 minutes
- 10 confirmations: ~20 minutes
- 60 confirmations (mined coins): ~2 hours
Merchant & User Tips
- Risk-based acceptance: For small tickets, 0–1 conf is common; for bigger orders, wait longer.
- Show the TX quickly: Provide the TXID or payment proof to the merchant if asked.
- Network conditions: During unusual network conditions, add a few extra confirmations to be safe.
Technical Details
A block is a container of transactions, with a new block being added to the blockchain once every 2 minutes (see constant DIFFICULTY_TARGET_V2 defined as 120 seconds), on average.
Blocks also contain a special type of transaction, the coinbase transaction, which add newly created Monero to the network. (source)
FAQ
Is Monero faster to confirm than Bitcoin?
Monero targets ~2-minute blocks vs. Bitcoin’s ~10 minutes, so comparable confirmation counts complete sooner in wall-clock time.
Do I ever need more than 10 confirmations?
For high-value transactions or where policy requires, yes—some services ask for 20+. Always follow the receiver’s stated policy.
Why 60 confirmations for mined XMR?
Coinbase (mined) outputs are intentionally locked longer (~60 blocks) before they’re spendable, a long-standing practice to strengthen security.
Summary: For most users, assume ~10 confirmations (~20 minutes) for fully unlocked funds, 0–2 for quick, low-value purchases (merchant permitting), and 60 for mined rewards.
Practical Rule of Thumb
For everyday spending, 10 confirmations (about 20 minutes) is the standard bar most wallets enforce before funds are fully spendable — enough to make a reorg effectively impossible for normal amounts. For very large transfers or exchange deposits you might wait longer, and freshly mined coins require 60 confirmations before they can be spent. If a transfer seems stuck, it's almost always just waiting for these confirmations, not lost.
