The safe transfer of gnosis metamSk does not say eip2930

As Ethereum developer, it is probably not strange to the complexity of interaction with intelligent contracts and an external portfolio. However, when it comes to transferring assets in many contractual interfaces, such as contract and safe gnosis, problems may arise quickly. In this article, we will deepen in why the use of EIP2930 in METAMASK configuration can cause errors out of gas (OOG) for its transactions.

EIP2930: short background

Ethereum Virtual Machine (EVM) 2.0 is based on the API web3.js and Ethers.js interfaces, which admit the standardized interface for interaction with intelligent contracts called EIP-2771. One of these interfaces is the EIP-2930, which allows transactions from one contract to another using a specific ABI interface (binary application interface).

Problem: Gas

When trying to transfer assets to many contract interfaces, such as between the contract and the Gnoss safe, calling the “Eip2930” function may fail due to an “external gas” error. This is because EIP-2771 allows direct connections between contracts, which can lead to excessive gas use if it is not administered correctly.

Problem with the use of EIP2930 in Metamask

In your case, use a Metamask to make a “EIP2930” connection from one contract to another. However, when trying to do it, the transaction fails due to errors outside gas. This can be attributed to several reasons:

4

• Failure gas budget : Without the appropriate gas budget, in their transactions it can end before they reach the planned destination.

• Incorrect configuration of the contract interface : ABI of your contract must meet the requirements of the EIP-2930 interface for the correct performance.

Solutions to overcome errors outside the game

To overcome these challenges and successfully use the EIP-2930 in the configuration of the metamas, follow the best practices:

1.

• Adequate order of connections

  

  : Be sure to order the contract to avoid errors out of gas correctly.

• Manage gas budgets : Implementation of gas budgets for each transaction to avoid excessive expenses.

• MONITOR TRANSACTIONS : be attentive to the progress of the transaction and adjust the order request or the gas budget if necessary to guarantee successful performance.

Following these guidelines, you must be able to make concessions successfully EIP-2930 in the Metamk configuration without finding errors out of gas.
