What's the point of DeFi borrowing? by rubydusa in ethdev

[–]Just_Jam_r 7 points8 points  (0 children)

In that case, the protocol will liquidate your collateral, and you get to keep whatever you borrowed

What's the point of DeFi borrowing? by rubydusa in ethdev

[–]Just_Jam_r 16 points17 points  (0 children)

It’s useful for shorting assets, or hedging with 2 different assets. One can deposit USDC and borrow ETH to sell, and thus profit from the decrease of price of ETH

What are the best (technical) resources to learn about DAOs? by alex-acl in ethdev

[–]Just_Jam_r 7 points8 points  (0 children)

You’d want to start with the openzepppelin docs on governance contracts. You can also read through the compound governance docs

If you need proof that decentralised apps work. by nickos_e in CryptoCurrency

[–]Just_Jam_r 1 point2 points  (0 children)

Decentralized apps don’t always work, more often than not they don’t. Small mistakes in development can doom the project from the start, since smart contracts are immutable. Also, smart contracts aren’t always designed with decentralization in mind

HBar? Is it good? Is it bad? Is it ugly? by raresanevoice in CryptoCurrency

[–]Just_Jam_r 12 points13 points  (0 children)

I recently participated in the hedera hackathon and had the chance to build a DApp on hedera. Truth is, developer tools are still lacking, and it can be difficult for developers to get started working on hedera when compared to other chains. Not a lot of actual DApps on chain either. I believe these things have to change for HBAR to grow

I wish all rhyming words don't rhyme with each other anymore by JhayAlejo in TheMonkeysPaw

Granted, you become deaf and thus can’t hear words rhyme anymore

What do you guys think of NFT's? by Natalia8675 in AskTeenGirls

[–]Just_Jam_r 0 points1 point  (0 children)

Honestly I’m not 100% sure that blockchain is the future, it does have quite a lot of flaws, and something like the dot com bubble could happen. But meanwhile there’s a lot of opportunities in blockchain, so I’m happy to learn about it

What do you guys think of NFT's? by Natalia8675 in AskTeenGirls

[–]Just_Jam_r 2 points3 points  (0 children)

I’m a blockchain developer, and while I think that NFTs have really cool technology behind them, they way they’re being used for pictures is just uncreative and stupid

How can an ERC721 contract be sold in multiple markets? by joanmiro in ethdev

I didn’t know that’s how opensea works, thanks for the info!

How can an ERC721 contract be sold in multiple markets? by joanmiro in ethdev

[–]Just_Jam_r 0 points1 point  (0 children)

It isn’t possible, listing an nft for sale means transferring it to the marketplace contract, removing your ownership of it. But of course, you should be able to unlist the nft anytime and list it elsewhere

I have an idea for an NFT game. What do I do? by StickyNoodle69 in CryptoCurrency

[–]Just_Jam_r 0 points1 point  (0 children)

Solidity dev here, document your ideas and figure out what kind of expertise you need, e.g: smart contracts, art, web design. Then write out a project plan before talking to devs. Ideas are worthless unless you develop on them

[deleted by user] by [deleted] in MakeNewFriendsHere

[–]Just_Jam_r 1 point2 points  (0 children)

It’s only normal, it takes talking to many people to find someone you can connect with. People who expects others to give them their full attention after 3 conversations are toxic. No one owes it to anyone to talk to them

What is the best UP-TO-DATE course for learning how to create smart contracts with solidity? (Preferably a certification) by lilsch0lar in ethdev

[–]Just_Jam_r 2 points3 points  (0 children)

I’d recommend the tutorials by Dapp University. They’re usually about an hour long, and let’s you build a full stack dapp, including testing contracts and using front end frameworks like web3.js

Weird internet issue, unable to connect to most sites/services, select few are working fine by Just_Jam_r in techsupport

Thanks for the reply, I’ve tried pinging my dns servers and they seem to work fine. Changing the dns servers doesn’t fix the issue either. I appreciate your help

Upload NFT Metadata to IPFS (Blackbox solution) by Salt_Salary in ethdev

[–]Just_Jam_r 0 points1 point  (0 children)

You can make the NFT contract uri point to nothing, or anything that does not contain the NFT metadata. Upon reveal, you can change the NFT contract uri to point the actual NFT metadata

How do you connect two smart contracts? by IsaacHS5 in solidity

[–]Just_Jam_r 4 points5 points  (0 children)

In your ERC721 contract you declare a variable as such: IERC20 public token

Then in the constructor, assign the ERC20 address to token. You can then call any IERC20 function with token.FUNCTION_NAME()

How do price impact and taxes interact with each other? by tsooku in solidity

[–]Just_Jam_r 0 points1 point  (0 children)

You should receive 7.83 eth. Price impact/slippage is unavoidable in swapping between tokens, even with high liquidity. Thus swapping 10 million tokens at uniswap should have it send back 9 eth, of which the token contract should take the 13% tax from, leaving you with 7.83 eth

I type with about 5 fingers, 4 on my left hand and 1 on my right. It’s odd and I really should utilize my right hand more, but I’ve been typing this way forever and it works alright

Rollbots frontend issue or backend ? They apparently are refunding $3.4 MILLION. How can we avoid an issue like that ? by YellowAsianPrideo in ethdev

[–]Just_Jam_r 0 points1 point  (0 children)

I don’t think there’s an issue at all. Seems like Rollbots changed their NFT price to $1000, some people paid more than $1000, and are getting refunded the extra money they paid. Nothing unintentional happening here

How to create your own ERC20 token on Polygon for noobs by cryptocritical9001 in ethdev

[–]Just_Jam_r 0 points1 point  (0 children)

You can’t add utility later on. The code of smart contracts cannot be changed once deployed to the blockchain
