StableCoins Cryptocurrency Escrow Service

Required Skills

What is a Crypto Escrow Service? An escrow service is a mediator service that keeps the money for a transaction in safekeeping until the Bitcoins are handed over. Escrow protects buyers from fraudulent sellers by requiring the Stablecoins to be deposited up front, before any money changes hands. In the event of a dispute, the escrow service will act as the arbitrator and determine who should ultimately receive the Stablecoins.

Need idea for developing smart contract

Posted by MOON WORLD

Required Skills

Hello. All.
Here is the idea.
We have Algo-bots make profit for sure.
It is well constructed, very safe to operate, generate steady income.
We actually have several bots and all of them generate profit over years.
Now, we want to have a project that raised the fund from users and invest it into trading and pay back interest.
Most of developers that I met suggested me building staking pool, mining pool etc.
Actually, there is too many exists already and most of them ends up with rug-pool.
We want to develop smart contract that can raised the fund from holders at the same time pay interest or reward to holders as they hold the tokens.
We prefer to have no staking involving way.
Buy idea or develop smart contract with idea provider.
Prefer to have BSC based contracts.
Pls reply me cost of work and idea if you have.
