A network of nodes validates blockchain transactions. The nodes earn crypto as fees, incentivizing them to process these transactions. Fees increase as users compete to achieve higher processing speeds when there are more transactions than usual on a blockchain. This sometimes happens when a particular cryptocurrency’s price increases. More users tend to move their assets around during these periods, leading to more transactions and higher fees.
Likewise, increased demand for a particular token leads to correspondingly higher fees. This happens when there is a lot of hype around a given project. Bitcoin transaction fees were relatively high when the Bitcoin-based protocol BRC-20 was popular in the spring of 2023.
Users’ options to avoid high costs
An obvious option is to wait for fees to go down before sending cryptocurrency, but it’s not feasible if you want to send it quickly. Fees can also be slightly lower during slow hours in leading markets, like nighttime in the US.
If a user is sending crypto to another exchange, they can exchange it for an asset like Ripple or Litecoin, whose fees tend to be lower. Then, they swap it back to their preferred asset on the other exchange. However, they’ll still be charged buying and selling fees.
A transaction simulation is an excellent way to predict fees, help keep crypto novices informed, and prevent mistakes. The simulation feature of Ambire Wallet, an open-source smart wallet that uses account abstraction, informs users of the effect of a transaction on their balances before they sign off on it. In addition to providing all the features and functions available from widely adopted solutions like Metamask, Ambire offers account recovery, prepayment of gas fees to avoid spikes, and transaction batching. It’s more affordable to send one large transaction instead of a few small ones. Blockchain activity determines the costs, not the amount of crypto you’re sending, so you’d pay the same fee for a small and a large transaction value. Ambire Wallet users combine transactions and broadcast them together, which saves both time and money.
The anatomy of transaction simulation
Ambire greatly alleviates the complexity of transaction simulation. The intricate process starts with defining input parameters and ends with assessing transaction outcomes. There are several critical stages, each contributing to the reliability and accuracy of the simulation results.
A series of input parameters defines the transaction’s behavior and features. These parameters include sender address, transaction type, receiver address, gas price and limit, and other relevant attributes. Users customize the simulation to accurately reflect objectives and scenarios, but not without meticulously defining these parameters. After defining them, validation procedures are performed to ensure the transaction’s integrity and feasibility. Validation involves verifying address authenticity and evaluating the parameters’ compliance with preset criteria.
Following validation, the simulation prepares the blockchain environment based on current data and system configuration. This includes retrieving relevant information, including, but not limited to, contract codes, account balances, and gas, which measures the computational resources consumed while the simulated transaction is being executed. Gas estimation involves evaluating the consumption of separate transaction elements and operations. Memory usage, opcode cost, and storage access are considered to accurately estimate the total gas required to execute the transaction. This determines the gas fees associated with the transaction.
Finally, the transaction simulation executes the operations entered in the input parameters. This stage involves simulating fund transfers, executing smart contract functions, and updating contract storage according to predetermined transaction logic. The simulation tracks each operation’s gas consumption during execution, monitoring the use of computational resources throughout the process. Tracking gas use makes it possible to assess how efficient transaction operations are and identify potential issues that may impact performance.
The simulation ends with an evaluation of transaction results, specifically the cost and integrity of the transaction. The evaluation involves verifying the completion of transaction operations, checking for errors, and examining the ensuing alterations to the blockchain state.
Simulations empower users to gauge the effectiveness of the entire process and attain valuable insights into the transaction’s impact on their finances, investment, and the whole blockchain.
Transaction simulation reduces risk
Even novices know that you can’t reverse a blockchain transaction. Once a user signs a transaction, they cannot change or undo it. Simulation lets them predict potential issues or consequences, greatly reducing the risk of irreparable errors. You can simulate swaps, trades, or liquidity provisions in DeFi interactions to make sure they won’t lead to unexpected losses ensuing from non-optimal trade execution or slippage.
Ethereum transactions can incur substantial gas fees depending on their complexity and the degree of network congestion at any given time. Simulating transactions provides an estimate of the gas required, preventing users from underpaying, which can lead to stuck or failed transactions. Overpaying is equally undesirable, as excessive gas fees inflate transaction costs needlessly. By providing accurate gas estimates, simulation makes it possible to set the proper gas limits and keep expenses in check.
The outcomes of blockchain transactions aren’t immediately apparent, especially if the transactions involve complex DeFi protocols or smart contracts. When voting in DAOs or implementing complex financial strategies, simulation helps users understand the implications of their decisions, leading to economically viable and safe choices. Ultimately, simulation clarifies the result of a transaction’s execution so involved parties are fully informed.
