Instant access: a secured APY-earning account

date September 18, 2019 time 4 min read 1854 views

Remember those halcyon days when banks paid 5% or more on deposits?

Today, you’re lucky to get half that. The 08/09 banking crisis put paid to sensible interest rates, and now you need to lock your money away to get close to past returns.

Some good did come out of the financial crisis, though: Bitcoin and the blockchain technology it’s built on. Together, they’ve created a new generation of financial applications that exploit blockchain tech for better returns.

Take your instant access account, for instance. It earns you 4% APY through an open-source, blockchain protocol. So how does blockchain manage to beat a centuries-old banking system?

Let’s take a look…

Compound Finance is a technology, not a bank

Compound Finance is not a bank nor does it hold any institutional licenses. It’s simply a protocol — a set of rules and instructions executed by blockchain programs called smart contracts. So how can a technology earn you better interest than a bank?

Well, it all boils down to the use of digital assets rather than physical ones. Just how Spotify has replaced vinyl and CDs, so are digital assets replacing things like money and property — and for good reason:

  1. They’re borderless, efficient, and flexible. Imagine the potential of programmable assets — they can go anywhere, near-instantly, and for free, and without any human interaction. The efficiency savings alone are huge (no branches, staff, or outdated tech to maintain).
  2. They can be tied to real-world assets. Think USD. The world is tokenizing rapidly and you can now find everything from gold to fine art represented by tokens on the blockchain.
  3. They can adapt to our global, interconnected, and rapidly-changing world. Many digital assets, including bitcoin and ethereum, aren’t classed as securities. This frees them from old-world rules that would’ve inhibited innovation, making them fit for the needs of today and tomorrow.

Compound Finance is one of many projects taking advantage of these benefits to help you earn better returns.

How Flex handles your deposits

When you deposit money into instant access, three things happen:

  1. First, we convert your deposit into a supported asset, with USD to preserve its value. 
  2. Then, we send your deposit to a collateralized liquidity pool — a fancy name for a pool of assets. For instant access, it helps to think of it as a lending pool, since that’s the function it performs.
  3. Once in the pool, your money converts to cTokens. These represent your balance, and allow the protocol to handle multiple asset types with ease.

Borrowers take loans from the pool in return for collateral, and the quality of the collateral determines how much they can borrow (called the loan-to-value ratio). This includes factors such as the value and liquidity of the collateral.

Investors — that’s you — earn the interest borrowers pay for the privilege of a loan from the pool. This rate varies, but for the moment is fixed at 4% APY.

This model isn’t new. Your bank does this already. They pool yours and others’ deposits together, lend them to borrowers, and keep most of the interest. But with the instant acess, you get the lion’s share.

Since it’s a lending pool, your deposits aren’t immediately committed to a borrower. That’s why you can withdraw your money anytime, for free and without penalty. As of today, the protocol manages around $152 million of stablecoins and other cryptocurrencies, of which your deposits will become a part.

Flex handles everything — it escrows collateral, processes deposits, transfers funds, and sets interest rates. Best of all, it’s all done automatically, saving a fortune on wasted admin costs, materials, and staff hours.

Algorithmic interest rates and anytime withdrawals

Compound Finance doesn’t discriminate between deposits. If your money is in the pool — whether borrowed or not — you earn interest on it, which is why it’s such a rewarding product.

The protocol sets interest rates algorithmically, according to supply and demand. The more people borrow, the higher the interest rate and vice versa. This encourages borrowing when the pool is liquid, and encourages repayment when the pool is running low.

The algorithmic interest rate therefore protects the promise of anytime withdrawals. Imagine if all the pool’s assets were borrowed — you’d need to wait for a repayment before you could withdraw your funds. But the more people borrow from the pool, the higher the rate, deterring further borrowing and encouraging people to repay.

So now we’ve covered interest, what about the security of the technology itself?

Is Compound Finance secure?

Blockchains are by nature secure technologies. Of course, there are extreme circumstances where they might be abused, but even the traditional banking system isn’t immune to vulnerability.

However, what makes most blockchains special is that they’re decentralized, meaning not controlled by any one person, group, or organization. Instead, transactions are validated by all the people connected to the network, so it’s very difficult to defraud.

However, there are some centralized points of failure to consider. One is the administrators of the Compound Finance protocol. They hold private keys that access administrator functions, such as interest rate setting and so on. If these keys were stolen, there’s a risk of theft in the same way a bank manager might embezzle customer deposits.

In both cases, however, they’re motivated to not commit such acts, otherwise their multi-million dollar businesses would fail. Also, Compound Finance has gone one step further by promising to pass administrator functions to users of the protocol in the future. So it will eventually become a Decentralized Autonomous Organization (DAO).

In the Flex account – What would happen if the value of the assets my USD has been converted to drops suddenly? Would my USD flex account lose value?

MyConstant Blog

Hi Mike. To clarify, the Flex (Instant access) account is based on USD, then it is not affected by the fluctuation of the price of other assets.
