When engaging in cryptocurrency exchanges, one of the most frequently asked questions by newcomers is: “How many confirmations are required for the exchange to be completed?” Confirmations play a crucial role in ensuring the security and finality of cryptocurrency transactions. On many platforms, including ours, the number of required confirmations has been optimized to balance both speed and security. This guide will explain what confirmations are, why they are necessary, and how many are needed for various cryptocurrencies.

What Are Confirmations in Cryptocurrency?

In the context of cryptocurrency, a confirmation is a verification by the network that a transaction is legitimate and has been added to the blockchain. Each time a new block is added to the blockchain that includes the transaction, the transaction receives one confirmation. The more confirmations a transaction has, the more secure it is considered, as it becomes increasingly difficult for anyone to reverse or tamper with it.

Why Are Confirmations Important?

Confirmations are essential for preventing double-spending and ensuring the integrity of the blockchain. Double-spending is a potential issue in digital currencies where the same coin is spent more than once. By requiring multiple confirmations, the network ensures that the transaction is legitimate and irreversible, thereby protecting both the sender and the recipient.

How Many Confirmations Are Required?

The number of confirmations required for a transaction to be considered complete varies depending on the cryptocurrency. Some cryptocurrencies require only one confirmation due to their robust security features, while others may require multiple confirmations to achieve the same level of security. Below is a summary of the confirmation requirements for a wide range of cryptocurrencies on our exchange platform:

• Bitcoin (BTC): Typically requires 1 confirmation, which makes it one of the fastest major cryptocurrencies for completing an exchange.
• Ethereum (ETH) and ERC20 Tokens: Generally require 4 confirmations. This includes popular tokens like Chainlink (LINK), Decentraland (MANA), and Shiba Inu (SHIB).
• Bitcoin Cash (BCH): Requires 2 confirmations. BCH is known for its faster transaction times compared to Bitcoin.
• Litecoin (LTC): Needs 2 confirmations. LTC is often chosen for transactions requiring quick settlement times.
• Monero (XMR): Requires 2 confirmations. Monero’s focus on privacy means that its transactions are not immediately visible on the blockchain, but the confirmation process ensures they are securely recorded.
• Ripple (XRP) and Stellar Lumens (XLM): Both require only 1 confirmation, reflecting their design for fast and low-cost transactions.
• Polkadot (DOT): Requires 3 confirmations. Polkadot’s multi-chain structure means that additional confirmations help ensure the integrity of transactions across its ecosystem.
• Cardano (ADA): Requires 15 confirmations. This relatively higher number reflects Cardano’s approach to ensuring secure and final transaction settlement.
• Avalanche (AVAXC): Requires 3 confirmations, leveraging its high-throughput consensus mechanism for fast and secure transactions.
• Solana (SOL) and Wrapped Solana (WSOL): Both require 1 confirmation, making them among the quickest options for transaction finality.
• USDT (Tether) and USDC (USD Coin): The number of confirmations required for these stablecoins varies depending on the network. For instance, USDT on the Ethereum network (ERC20) requires 4 confirmations, while on Solana, it needs just 1 confirmation.
• Ethereum Layer-2 Solutions (Arbitrum and Base): Require 20 confirmations for ETH and other ERC20 tokens like USDC and WETH. These Layer-2 networks are designed to offload some of the traffic from the main Ethereum chain, requiring additional confirmations to ensure secure and reliable transaction processing.
• Polygon (MATIC): Requires 30 confirmations. As a Layer-2 scaling solution for Ethereum, Polygon’s longer confirmation time reflects its approach to achieving consensus across its network.
• Tezos (XTZ) and Zcash (ZEC): Each requires 4 confirmations, balancing between speed and security.
• Dash (DASH): Requires 1 confirmation, known for its InstantSend feature, which enhances transaction speed.

Special Considerations

Some cryptocurrencies, like EOS, have much higher confirmation requirements. EOS requires 100 confirmations due to its unique delegated proof-of-stake (DPoS) mechanism, where transactions are validated by a small group of trusted nodes. Similarly, Ethereum Classic (ETC) and Polygon’s native token (MATIC) both require 30 confirmations due to their respective network security concerns.

It’s also worth noting that certain wallets or exchanges may impose additional confirmation requirements beyond the standard minimums for added security, particularly in high-value transactions or during periods of network congestion.

Understanding the number of confirmations required for each cryptocurrency is crucial when performing exchanges. While some cryptocurrencies allow for nearly instant transactions with just one confirmation, others may require several confirmations to ensure the security and integrity of the exchange. By familiarizing yourself with these requirements, you can better manage your expectations and ensure a smooth and secure transaction process.
