    La idea es crear un proyecto MLM, pero no programado como se hace habitualmente, quiero programarlo con contrato inteligente, con el fin de asegurar y automatizar los pagos de comisiones a los afiliados participantes en el proyecto. Básicamente constaría de una web donde los usuarios se puedan registrar con un link de afiliado, y acceder a un BackOffice donde ver los productos a la venta, al realizar el pago con una cripto que podría ser BUSD, se repartirían las comisiones programadas en cada nivel, directamente a la billetera del que recibe las comisiones, la matriz seria una matriz Unilever de 5 niveles.

    Hello, I would like to to create a new token on Polygon or/and Binance smart chains. I will see if I proceed with 1 chain or 2 according to the price. I have three questions which you can include with your bid: 1) How much does it cost to have a new token created on polygon? How much for BSC? 2) What guarantee do I have that you won't have full access to this token since you create it for me? If your rates are competitive, I will also use your service to create a smart contract so people can deposit lets say BNB to the smart contract with metamask and claim my new token in return as a proof of deposit. 3) How much would you charge for this smart contact? (Do not include this in your bid! This is the next step but please PM me the price) Thank You

    I have 9999 NFT collection made with Hashlips Solana build, along with Solana Metadata. I was going to upload to MagicEden, but I hear it is better to mint on Solana with IPFS just like Ethereum. I have a half finished WordPress domain, and I was previously set up for staking with Etthereum, but decided to change my mind. So I need the following: - A token made using Solana Blockchain - The only way to get the token is to have one of my NFTs staking on my website - I need help with the smart contract to allow this, and the website implementation. Thank you, if you read all of this, please say the codeword NO ETHEREUM when speaking to me. If you help, I will also give 10% of profits. Thank you.
