I’m midway through building an AI-driven sports-betting platform and now need to wire the product into the Ethereum network. The work is purely blockchain integration: everything else—UI, odds engine, user management—is already in place. Core goals • Connect the existing back-end to Ethereum so wagers, settlements, and payouts live on-chain. • Design and deploy Solidity contracts that handle bet placement, result verification, and automatic distribution of winnings. • Expose clean, well-documented endpoints or SDK hooks so my team can trigger contract calls from our current codebase. Acceptance criteria 1. All wager events emit verifiable on-chain logs viewable in common explorers. 2. Contract functions execute within current gas-cost best p...

Title: Web3 Sales Closer Needed: Sell-Out 10K NFT Genesis Batch (Phoenix Protocol) Overview: I have the strategy. I have the treasury-backed protocol on OpenSea. I need a Sales Executioner. Lux Lucen is launching the Phoenix Protocol—a 10,000-piece NFT genesis batch on Polygon. I am not looking for someone to "build a roadmap" or "consult." I am looking for someone who can drive verified sales today. The Mission: We have a mathematical "guaranteed exit" model ($0.125 mint price / $0.10 liquidity floor). It is a superior, treasury-backed product. My only hurdle is volume. I need an operator who can identify, reach, and close high-value NFT collectors who value liquidity over hype. What You Will Do (Sales Only): Direct Outreach: DMing, networking, and ...

I need help crediting my Redotpay wallet with USDT. The balance will be coming from my own personal wallet. For the network, I indicated “Redotpay” because the app itself does not make the underlying chain obvious, so I will rely on you to confirm whether I should send over Ethereum (ERC-20), Tron (TRC-20) or Binance Smart Chain (BEP-20) based on fee structure and compatibility with Redotpay’s deposit addresses. Here is what I am looking for: • Clear, step-by-step instructions to generate the correct deposit address inside Redotpay and verify it matches the chosen chain. • Guidance on any required minimum amount, confirmations, or reference fields Redotpay may ask for during the transfer. • A quick safety checklist so I can double-check everythi...
