I am in the process of porting hundreds of Node.js source code files to deno. I have encountered a number of interesting problems porting the code and found some solutions. Here’s a list of problems and solutions. …

Note: A diamond is a contract that gets its external functions from other deployed contracts called facets. A diamond implements the diamond standard. In my last article about storage layout I explained how storage layout works in Solidity and I showed three different ways proxy contracts and diamonds handle storage…

Note: A proxy contract is a contract that delegates its function calls to another contract called a delegate contract or logic contract or facet. A diamond is a contract that can delegate function calls to different contracts called facets. Diamonds are specified by the diamond standard. …

If you get this error it probably means you have too many function arguments, local variables or return values in your function. Christian Reitwiessner, creator of Solidity, says this: There are several situations in which this or similar errors occur. Most are related to too many local variables, parameters or…

The diamond standard is a new architecture for upgradeable contracts. The diamond standard was just updated to include the following summary about why to make diamonds: The flexibility of this standard makes a lot of designs possible. There are reasons to make diamonds that the author of this standard doesn’t…

NOTE: The Diamond Standard has been released. Make a user interface for that instead. See here: https://github.com/ethereum/EIPs/issues/2535 The transparent contract standard, ERC1538, is an upgradeable contract architecture that provides the following functionality: A way to add, replace and remove multiple functions of a contract atomically (at the same time). Standard…

mokens.io yet again has a big new change. Before today a person could create and own a new moken by submitting information about the moken and paying some ether. That changes today. Mokens are proposed on the mint webpage. No fees are paid for this. MetaMask is not even needed…

I want to let you know about some changes to mokens. The purpose of the mokens project is to create and trade valuable mokens. All changes that have been made have been done to support that purpose. The term ‘era’, which is a set of mokens created during a time…

Mokens.io was one of the very first dapps that enabled people to create their own cryptocollectibles. I would say it was the easiest tool for someone to create cryptocollectibles. A person just filled out a short form and submitted a transaction using MetaMask and voila, a new cryptocollectible was born…
