How Long Does It Take To Transfer Ethereum (ETH)

Transactions on Ethereum are far from uniform. The length of time required for each can vary dramatically and a variety of factors can influence the time it takes for a transaction to get from A to B. This can leave some users wondering why an ETH transfer is taking so long and leave others surprised when a transaction comes through surprisingly quickly.

In this guide, we will examine how long it takes to send Ethereum, break down what factors influence Ethereum's transaction times, and outline how long, on average, it takes to complete wallet-to-wallet and wallet-to-exchange transactions.

How Fast Are Ethereum Transactions?

The Ethereum blockchain can process 13-15 transactions per second (TPS). It is a figure well known and well quoted within the cryptocurrency industry. However, that figure does not reflect the time to complete a wallet-to-wallet or wallet-to-exchange transaction via the blockchain. Depending on the transfer method, ETH transfers can take between 1 minute and 30 minutes.

How Long Does It Take To Send ETH Between Wallets?

The time required to send ETH between wallets depends on the type of cryptocurrency wallet being used. If transferring Ethereum from a hot wallet that is already connected to the internet, transaction times will be slightly quicker when compared with sending assets from a cold wallet. Cold wallets will need to be connected and then unlocked before transactions can be completed.

Once both types of crypto wallets are connected to the internet, an average wallet-to-wallet Ethereum transaction takes between 1 minute to 15 minutes depending on the congestion of the network. Most cryptocurrency wallets do not require a high number of confirmations before assets are transferred. While the speed of the transfer is not as fast compared to other networks such as XRP and Solana, it has one of the fastest average transfer speeds.

How Long To Send ETH From A Wallet To Exchange?

For wallet-to-exchange transfers, the transfer speed for Ethereum can take slightly longer due to the number of confirmations required. Most exchanges require several confirmations of the Ethereum blockchain before digital assets are transferred. Based on estimates from exchange platforms, wallet-to-exchange transactions can take anywhere between 5 minutes and 30 minutes.

The number of confirmations improves security and ensures transactions are valid. However, this does mean moving Ethereum-based assets onto and off an exchange can take slightly longer than completing a wallet-to-wallet transfer.

However, it is important to remember that estimates provided by most exchanges often assume that an Ethereum transaction will be included within the next block. At times of high congestion, this is unlikely to be the case. It may take several blocks before a transaction is finally processed.

What Factors Affect Ethereum Transaction Times?

All transactions sent via the Ethereum blockchain are grouped into blocks. Each new block is added to the blockchain by a miner, who validates each transaction and then broadcasts the set of transactions to all other miners within the network. This process, which is part of the blockchain’s Proof-of-Work consensus mechanism, ensures that all transactions are correct and accurate.

While the PoW consensus mechanism does not change, there are several factors that can influence how long it takes before a single transaction is added to a new block. These can be broken down into two categories: (1) internal and (2) external factors.

Internal factors affecting Ethereum transaction times

  • Block time. Block time is defined as the amount of time required to find a solution to the Proof-of-Work algorithm and add a new block to the blockchain. The block time for Ethereum averages 12-14 seconds, which is how frequently a new set of transactions is added. Although the block time varies occasionally, the difficulty of the mining algorithm ensures that block times remain around the 14-second mark.
  • Block size. The number of transactions that fit into each Ethereum block is known as the block size. Unlike block time, the block size of Ethereum is not consistent and can vary depending on network usage. Ethereum developers have limited the average block gas limit to 15 million gas (slightly less than 1MB), however, the true figure can vary anywhere up to that point. According to data collected by the Ethereum blockchain explorer, Etherscan, in the first quarter of 2022, block size averaged 90KB, with a maximum block size of 119KB and a minimum block size of 81KB.
  • Gas price. Every transaction completed via the Ethereum network is accompanied by a gas fee, paid in the native coin, ETH. This fee is paid to miners who process transactions and secure the blockchain. The total gas fee is composed of the base fee, which is the minimum required to include a transaction, and tips (priority fee), which are optional and can be added to ensure a transaction is completed quicker. All miners within a network can see transactions that have a tip attached, which is why those transactions are more likely to be processed first. If a user is willing to pay a high tip, Ethereum transaction times can be significantly lower.

External factors affecting Ethereum transaction times

  • Network congestion. How busy the network is can greatly influence the length of Ethereum transactions. Due to its popularity, the Ethereum blockchain has continually struggled to handle the demand from decentralized applications (dApps) and end-users. As a result, at times of high network congestion, the blockchain cannot scale and automatically adjust to keep transaction times stable. When there is an influx of transactions, the length of time required to process a payment on Ethereum tends to increase.
  • Destination address. Ethereum wallet addresses are the final factor that can affect transaction time. Some wallet addresses are linked to personal cryptocurrency wallets. Others are linked to exchange-based cryptocurrency wallets. To promote security, wallet service providers can introduce variations in the number of confirmations required on the blockchain before digital assets are transferred. Due to the importance of this factor, we have included a section below to explain how many confirmations Ethereum requires.

Can You Check Ethereum’s Network Congestion?

While there is no direct tool for checking the congestion of the Ethereum network, the business of the network can be estimated from the transaction gas fees. A high Ethereum gas fee would infer that the network is suffering from a high volume of users. Gas fees then tend to drop when the volume of users decreases. The average Ethereum gas fee can be found on an Ethereum blockchain explorer, such as Etherscan and Ethstats.

Checking the network’s gas fees is a good precaution to take and should provide a decent expectation for how long an Ethereum transaction may take. Once a transaction is submitted, the status of a transaction can also be followed using an Ethereum blockchain explorer.

What Are Confirmations?

As digital assets or coins are sent from one wallet to another or from a wallet to an exchange, there can often be requirements regarding the number of times the data must be validated by the blockchain - known as a confirmation. Assets are only transferred once a predefined number of confirmations has been reached. The predefined number of confirmations varies depending on the destination address.

One confirmation is achieved when a transaction is first added to the blockchain. A subsequent confirmation is then achieved each time a subsequent block is added. As each confirmation is completed, the transaction’s validity increases meaning that it is far less likely to be reversed.

How Many Confirmations Does Ethereum Require?

Exchanges will typically implement the highest confirmation requirements to ensure that transactions are accurate. This can increase the transaction time required. The number of confirmations required to complete an ETH transfer to the top-ranking crypto exchanges is:

  • Crypto.com: 12 confirmations
  • Kraken: 20 confirmations
  • Coinbase: 35 confirmations.

How Does An Ethereum Transaction Work?

Ethereum runs on a Proof-of-Work (PoW) consensus mechanism. This involves a process called mining to validate and verify each of the transactions on the Ethereum network. The miner that finds a solution to the mathematical formula first and, therefore, proves a certain level of computational work has been used, updates the Ethereum blockchain.

In return for processing the transaction, the miner is given an ETH block reward. A new block, containing new transactional and smart contract data, is added to the Ethereum blockchain every 13 to 15 seconds. Ether transfers occur between wallets that involve a public and private key.

  • Public key. A public key is a string of unique numbers and letters that can be shared when an Ethereum owner sends and receives ETH transactions. In a way, the public can is similar to the account number for a bank account.
  • Private key. A private key is used to sign transactions processed by the cryptocurrency wallet. It comprises a random string of numbers and letters. While a public key can be shared with anyone, a private key to an Ethereum wallet gives control of the stored assets and must be kept safe at all times.

Will Etherem 2.0 Make Transactions Faster?

The change to Ethereum 2.0 will convert from a mining to a staking process to win a block of transactions to validate. The change will dramatically reduce the energy requirements, improve scalability, and will speed up ETH transactions. According to Vitalik Buterin, the full implementation of Ethereum 2.0 will increase the speed capability from 13-15 TPS to an estimated 100 TPS.

Conclusion

The time required to send Ethereum-based digital assets is far from consistent, which understandably leaves many investors frustrated and questioning why these variations in transaction times occur. With adaptive block sizes, priority gas fees, changes in network congestion, and confirmations all playing a factor, transaction times can vary considerably for end-users. Although, the time taken to send an Ethereum transaction is much faster than Bitcoin.

Due to a low number of confirmations, wallet-to-wallet transactions are typically the quickest type of Ethereum transaction taking place within the blockchain. Wallet-to-wallet transactions can take anywhere between 1 and 15 minutes. Meanwhile, for those transferring assets from a wallet to an exchange, a longer transaction time should be expected due to the higher number of confirmations required by most cryptocurrency platforms. At times of high network congestion, a transaction time extending beyond 30 minutes is not unreasonable to expect.
