Embrace low and no transaction fee with MobiFi app — Polygon Integration

ETH gas fee is always to the moon when you want to trade. DeFi sucks with a high gas fee, and nothing works under such circumstances.

So does the MobiFi app; it will never work if the user has to pay a $10 gas fee because of a $5 parking fee or a 3$ bus ticket. Therefore, I want to talk about how the MobiFi team designed and mitigated the high gas fee on ETH.

What we do in MobiFi

In MobiFi’s architecture design, we have two tasks to complete.

  1. Offer mobility services, including payment, etc., to provide an end-to-end experience.
  2. Help users save money and make money with crypto-financial services and products.

Task 1. It’s close to our everyday life, so it’s pretty self-explanatory. People need to make many micro-payments, which are usually below $10. It has no sense if, on top of $10, you still have to bear a transaction cost of $10. Btw, transaction cost/service fee is the primary business model for all the transport operators and banks, of course, 😉.

Task 2. When talking about crypto-financial services and products, it can be staking, borrowing, and lending, in other words, DeFi. Smart contract in DeFi is complex and cost more gas fee than simple transfer.

For task 1, we also face potential regulation issues with cryptocurrency, thus the Dual-Token design. We minted a fiat-backed stable token on the Corda ledger, i.e., SMile token. Technically speaking, it is a token, only tradable inside our Corda-based ecosystem. Users cannot trade it directly on an exchange. More info about dual token and SMile can be found on our website: Dual-Token

Oh, I forgot to mention, there is zero transaction cost for SMiles. ZERO, ZERO, ZERO 🤟

For task 2, in our first beta release, the MobiFi app will support MoFi rewards distribution automatically in a small amount. Based on pre-defined eco-friendly travel behaviors, we unlock and distribute MoFi on a very frequent basis and with a small amount usually ;-)

For example, if we have 1000 users. And if we distribute them 1 MoFi each, that will cost us $20 per transaction (~66 gwei). So with 1000 lovely eco-friendly customers, we have to pay $20,000 so that each of them gets 1 MoFi.

We need a much LOW LOW LOW transaction fee solution!

Polygon

Polygon is an Ethereum layer two solutions that is faster, cheaper, more scalable. https://polygon.technology

We are delighted to announce that the $MoFi token is now mapped on Polygon, and you can use Polygon bridge to move your token back and forth if you want. But the most important thing is:

We can frequently run a large amount of mini-transaction to make our financial system work for our end-user.

Let’s use the same example above, 1000 users, we reward them each with 1 MoFi token. It will cost about 0.00063 MATIC at the time of writing. That’s about $0.0013, so 1000 users will cost us $1.3.

$1.3 vs. $20,000 🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄🙄

The number just doesn’t lie, and it’s a clear cut.

Polygon is by far the most adopted scaling effort in the Ethereum ecosystem, with 3,000+ applications hosted, 1B+ transactions processed, 100M+ unique user addresses, and ~$5B+ in assets secured. That means, by integrating with Polygon L2 POS Chain, MobiFi can bring fruitful DeFi products to help further our mobility users earn passive income while enjoying an eco-friendly travel experience.

Looking forward

MobiFi brings in its revolutionized financial technology built on blockchain and cryptocurrency to change the mobility industry’s status quo. The goal is to make the mobility service as cheaper as possible and give back the money to the users. Eventually, users can contribute back to the environment.
