@BillBaily Thanks but I was looking for a larger piece of HTML, covering both iframes.

But another suggestion - I have seen on another project that uses WorldPay has nested iframes, so you would need something like

to test locally you need to make use of mocks which can simulate having an oracle network. Because you're working locally, a Chainlink node doesn't know about your local blockchain, so you can't actually do proper VRF requests. Note you can try deploy a local Chainlink node and a local blockchain and have them talk, but it isn't fully supported yet so you may get mixed results. Anyway, as per the hardhat starter kit that you linked, you can set the defaultNetwork to be 'hardhat' in the hardhat.config.js file, then when you deploy and run the integration tests (yarn test-integration), it will use mocks to mock up the VRF node, and to test the requesting of a random number. See the test here, and the mock contracts and linktoken get deployed here

Advice/opinion

A database is for persistent storage of numbers and text.

An app is for computing and deciding things.

That is, the complex business logic you describe may be more appropriately encoded in Java (or other app language). Meanwhile, the breakpoints, etc for interest rates should be stored in the database.

Phrased differently: "Business logic" belongs in the app, not the database. (There is, of course, a gray lines between them. For example, SQL is excellent at summing up all the data in a table; so, I would do that in SQL, not Java.)

Decimal

Banks have picky rules that may not be the same as what DECIMAL or DOUBLE provide -- in Java or MySQL or _any other computer language. Be careful of the rules that may be required. In particular, DECIMAL(10, 4) is unlikely to be adequate in your application. On the other hand, apy DECIMAL(4, 2) may be adequate if that is what is presented to the customer. But, again, beware of rounding rules when generating that number. You may be forced to enter that number manually.

Be aware of the difference in rounding characteristics between DECIMAL and DOUBLE.

Answer

If you choose to implement an algorithm in the database, then see CREATE STORED PROCEDURE and CREATE FUNCTION.

Stored Procs can be used to encapsulate a set of SQL statements. It can receive and send strings and numbers, but not arrays. It is capable of reading tables (hence "arrays" of a sort.)

Functions can be called anywhere an expression can occur. It can receive some numbers/strings and produce one number or string.

Array

I'm not clear on what is needed, but I envision a table of a few rows or a few dozen rows with each row saying "for values up to $xxx, use y.yy% interest rate".

Stored Procs have "cursors" and "loops" but they are clumsy; the app language is likely to have better code.

If you add to the .topnav a:hover transition:linear 0.8s; this will give to the navbar a effect. Hope this works for you. Or you can add transition:ease 0.8s.

it appears your env variables are not set correctly, and it looks like in this case it's your WEB3_INFURA_PROJECT_ID.

You can fix it by setting the variable in your .env file and adding dotenv: .env to your brownie-config.yaml.

brownie-config.yaml:

dotenv: .env .env:

export WEB3_INFURA_PROJECT_ID=YOUR_PROJECT_ID_HERE Remember to save these files.

Additionally, you should be on at least brownie version v1.14.6. You can find out what version you're on with:

brownie --version

Both codes return hex encoded as private key

What you're looking for are slash command groups. You would create a SlashCommandGroup, then instead of the standard bot.slash_command, you would use SlashCommandGroup.command.

The code below shows an example with /verify help

Not possible by design.

A contract address is determined from the deployment transaction params. Specifically, the ethers deploy() function is using the CREATE opcode by default, so the contract address is determined from the deployer address and the deploying transaction nonce param.

But the private key to the contract address is never generated during the deployment - so it can't be returned. Just the address.

Because otherwise I can't call the transfer method on the smart contract.

Correct. If you want to transfer funds out of the contract, you need to implement a function to be able to do that.
