Recently announced partnership between Renfter, an Uncollateralized NFT Renting Protocol and SKALE, an Ethereum native, modular blockchain network will not only bring benefits to already existing projects but to the projects that are still in the building phase as well or are looking for new chains to span.

Unlike other multi-million grant programs, this one was specially designed for up to 10 best teams that will be accepted. The amount each project can get ranges between 10 and up to $50k depending on the value the project brings into Renfter & SKALE Ecosystem.

“Our focus is on quality and not quantity. We wanted to create a program that will support projects in the best possible way, not to boost our Twitter accounts with “Project x is now building on SKALE and implements Renfter”. Having maximum of 10 projects we can be sure we are able to give full dedication of our time and resources to each team and still have enough exciting new projects joining the ecosystem” - Petar Popovic, Founder & CEO at Renfter

5m SKALE tokens allocated as financial support

Long-term support for teams with marketing, development, education, etc…

All interested projects can apply for the grant by submitting this form.

You've all probably heard of BoredApe, MutantApe, Azuki, and Doodles, but how many of you know what’s considered to be the first NFT ever?

In May of 2014th, on the Namecoin Bitcoin fork, the first NFT "Quantum" was minted. It was long before the term NFT had even been coined, but we can still say that it was the first NFT ever, or at least NFT Lucy.

Terra Nullius was the first NFT on ETH, it was minted on 8th of August 2015th and is designed to allow users to stake a claim on a blockchain.

Interestingly, the founders of this project did not categorize their project as an NFT but rather an Interactive Ethereum contract.

Peperium project was designed to enable users to trade memes on the blockchain. The mint kicked off in October 2016 but the collection was not traded until March 2017. Peperium was inspired by Pepe and the meme culture that is more than accepted in crypto. This is arguably the first NFT collection that had a community gather around it

CryptoPunks mint in June 2017, and four years later they changed the NFT scene forever. Created by John Watkinson and Matt Hall, they were the first NFT project to go mainstream and start attracting more people to the NFT space. In addition, they were the inspiration for the ERC-721 standard that most NFT projects use today. They have been mentioned in The New York Times, Christie's of London, Art|Basel Miami, and The PBS NewsHour. The most expensive sold was CryptoPunk #5822: $23.7 million (8000 ETH).

Just three months after that, in September, the first draft ERC-721 proposal was published by Dapper Labs CTO Date Shirley, which included the first formal usage of the term NFT.

In November, the same people responsible for submitting Ethereum Improvement Proposals were responsible for crashing Ethereum when they released the first NFT blockchain game CryptoKitties. The project itself was a big hit that caused unprecedented transaction volume on Ethereum shortly after launch.

After the 2018 crash, the whole web3 space was in some kind of hibernation mode. Nothing special was happening, but by the end of 2020 things started to change. Bitcoin was going up and the rest were following. The new rise had an impact on NFTs too, but we can say that NFTs had an impact on and contributed to the rise too.

OpenSea and Metamask became more accepted. Major art organizations began to feature NFTs in their exhibitions. Sotheby’s was doing auctions where they accept ETH Crypto galleries opened up and a large number of artists started selling their paintings as NFT.

The first Solana NFT project and the awakening of the market at Solana

It is debatable which is the first NFT to be minted on Solana, some say it is  Kreechers some say it’s Solarians. Kreechers minted off-chain, which is different from the usual minting process today. Solana's NFT scene has progressed a lot, with a lot of serious and strong projects like DeGods, Degenarete Ape Academy, Aurory, Portals, Nyan Heroes and OkayBears. That changed the meta and set new rules in space. 

In 2021, we could see a lot of jump in the market, and a more exponential growth, which is contrary to the events that took place from 2018 to 2020. The NFT market is still young and very susceptible to rapid changes. It remains for us to follow and try to predict every change. 

The NFT space is known as a mostly male-dominated industry, but it might not be that way in the future. More and more women are entering the NFT space and starting to build their careers. Which is quite important for mass adoption. The NFT industry will start to focus more on social change and environmental change, not just on pure technology or flipping. The NFT market will surely improve a lot compared to today and it will be interesting to see what we will have to talk about next year on International NFT Day.

On behalf of the Renfter team, I would like to wish you all a happy International NFT day — what a crazy year it’s been. So many exciting events, the rise and downfalls of big NFT projects, and the overall growth of our entire industry.
All of us can say that we made history and were among the first to set foot on the soil of the wild west called NFT space. Setting alarms at 3 am to mint NFTs and smashing keyboards when we weren’t able to mint them

Happy International NFT Day

When NFT renting was a fresh and new idea, the first few primitive solutions appeared and they were all based on collateral as insurance.

We can say that because it was a completely new idea, something like that was ok back then. It was fine for the first prototypes and idea validation, but it wasn’t good enough for real use.

You wouldn’t even have to scratch beneath the surface to realize there are many problems that had to be addressed that collateral couldn’t solve.

The biggest issue was that collateral wasn't the ultimate guarantee that you will get your NFT back from the borrower once you transfer it. Second, when it comes to liquidity and speculation NFTs are much more volatile than tokens. And lastly, how much an NFT is worth is an extremely subjective thing.

It’s just like your grandfather's watch, a family loom.

If you take it to the pawn shop they will probably estimate it much lower than you and your parents would as it has sentimental value for you, whereas for the pawn shop worker it’s just some cogs assembled to show the time with a leather belt.

So, it was clear that there are problems, but was it clear what the solution may be?

What we needed was a smarter way and a trustless solution


The natural step was that better and smarter ways of renting NFTs will soon appear. One that doesn't rely on collateral but on other mechanisms of insurance. And that’s exactly how and why Renfter came to be.

Instead of relying on collateral, we decided to rely on the very own technology NFTs consist of, smart contracts.

Our primary goal was to protect lenders and create a solution where the collateral isn’t even needed because there's a much better and more reliable way of protecting users' NFTs.

By doing so we also removed an entry barrier for borrowers as well. Borrowers now only have to pay for the renting price without needing to put 10 times more NFT worth as collateral which will act as a “security”.

So how did Renfter solve the collateral-free NFT renting puzzle?

Our approach was actually very simple and straightforward (which doesn’t mean it didn’t come with its own challenges).

The only way we can guarantee for other people NFTs, without inventing a completely new standard, was to never transfer them to another person, i.e. borrower.

Lenders should transfer their NFTs to the protocol where they should be safely and securely kept the whole time, and only limited access should be given to the borrower. This approach required the issuance of a wrapped version of the NFT that would act as proof of usage rights and a key. Transferring, burning or similar actions of original NFTs should be impossible.



Because original NFTs would never leave the protocol, it meant that the protocol itself should do everything and act as a source of truth. That also meant that:

Anyone should be able to verify who is the original owner of the NFT, i.e lender

Anyone should be able to verify who has the current rights to use the NFT at the moment, i.e. who is the borrower

NFT functionality should be executable by the borrower (even though the borrower is not the real owner)

But, even though the idea was straightforward in its essence, there were some interesting questions and challenges that became obvious almost immediately and that we had to address.

1. What happens if there’s an airdrop or some rewards for NFT holders during the renting period?

2. How can we be sure that the borrowers won't call some potentially destructive or malicious custom functionality?

I’ll try to answer both questions as simply as possible without going into too much technical detail for now (both questions could be topics of their own and articles, and probably will be :D).

We had to develop a feature where lenders can decide, before renting, whether they are going to keep all rewards for themselves, give them to the borrowers, or split them on a certain ratio. And we came up with a solution, even though it's still in the testing phase and works only with verified collections.

As for the second question, the best approach in our opinion was what is called “The principle of least privilege” which is the best practice for decades in software engineering and cybersecurity. By default, all custom token functionality should be explicitly whitelisted by the lender in order to be executable by the borrower. By default, everything is forbidden. That’s the only way we can be sure there won’t be a misuse of original tokens.

Recently, during an interview with @drumkoon, we got interesting food for thought that lead to making that feature even more powerful and giving the lenders an option to say how many times the whitelisted functionality can be executed. Of course, we decided to implement it immediately. 

So, by solving these two really important questions we wrapped around all the necessary functionality an NFT renting protocol should have.

And lastly, we made it to be pretty flexible and composable so anyone can build whatever they need in case we didn’t already cover it.

We recently launched a public beta on Polygon Mumbai testnet. It has only one collection enabled, Renfter Demo Collection, but it’s a perfect showcase of the power and possibilities of our take on the uncollateralized NFT renting protocol.

Any feedback is more than welcome, you can leave it on our Discord server and that’s the place where you can ask for help in case you need it. We have recorded an explainer video too which you may want to watch before trying everything by yourself.

If NFT renting itself is something that will disturb the whole space, and push crypto and NFTs towards becoming mainstream and widely adopted, we can freely say that uncollateralized NFT renting is a paradigm shift that will disturb the disturber itself.

ETHBarcelona Side Events

Collateral acts as really poor insurance as it can't guarantee that your NFT will be given back to you once you transfer it to the renter. You have to blindly trust another person and place your bet on renters honesty.

Renters can abuse your rented NFT to unrightfully claim airdrops

Lack of Passive Income Opportunities for the NFT Holders

Lack of Opportunities for Non-Holding NFT Communities

Using very own technology of programmable blockchains, i.e. Smart Contracts, to create a renting protocol that is not based on collateral as insurance and that would act as a single source of trust.

Such protocol should ensure that upfront decided terms and deals between lenders and renters are met no matter what.

You'll be able to predefine on how long do you want to rent out your NFT, will renter have the right to claim potential airdrops and you'll be able to even predefine if you'll want to split the revenue generated out of the usage of the NFT.

IRL example: Let's say there's a Play&Earn/Walk2Earn game. On the one side, you have an NFT collector who's not really into gaming/walking, but on the other side you have someone who's a really good gamer/athlete, but doesn't have the capital to buy the NFT itself in order to start earning... They'd be able to agree, to let's say, 50%-50% revenue share, where the NFT collector participates with the NFT itself and gamer/athlete does the actual gaming/walking... NFT Collector gets to earn passive income, while the gamer/athlete gets the chance to earn additional income doing something they love... Also, looking on the long term, gamer/athlete is most likely to buy the NFT once he/she earns enough money, thus creating the additional demand for the NFT projects while turning a non-paying customer into a paying customer.
