I need an engineer who can take the current TRON code-base and CLONE it into a clean, standalone network that runs on just three validator nodes, using Delegated Proof of Stake (DPoS) as its consensus. The goal is to have a lightweight but fully functional chain that preserves TRON’s performance advantages while letting me control every aspect of the environment. Key capabilities I want built in from day one are smart-contract execution (Solidity-compatible), on-chain token creation/management, and a governance layer so stakeholders can vote on upgrades or parameter changes. I do not have a rigid block-time requirement; please recommend the most practical interval for a three-node DPoS setup and be ready to justify the choice from a throughput and finality standpoint. I expect the ...

I’m looking for help opening fresh accounts on a major cryptocurrency exchange through my referral link. After you register with the code I supply, you’ll need to pass the platform’s full KYC verification. Once the exchange confirms your KYC status, I will transfer 30 USDT to the new wallet so the account shows an initial deposit; for every account that reaches this milestone you’ll earn an additional 10 USD in compensation. The exchange name, referral link, and any specific KYC instructions will be shared privately. You must use legitimate, verifiable personal documents that meet the exchange’s standards—usually a government-issued photo ID, recent proof of address, and a selfie for facial verification. Accounts must be unique, tied to real identities,...

I’m looking for an experienced Web3 developer to build a small blockchain ecosystem on a testnet within one week. The project will include a simple token launchpad where users can create and deploy their own tokens by entering basic details such as token name, symbol, supply, and decimals. I also need an ERC-20 compatible token system with properly tested and deployed smart contracts on the selected testnet. The project should include a simple DEX/AMM where users can swap supported tokens and add or remove liquidity through basic liquidity pools. A clean and responsive frontend DApp is required with wallet connection, token creation, token listings, swapping, liquidity management, and transaction status. The frontend can be built with React or , using Solidity for smart contract...

I’m planning to roll out a full-featured crypto wallet that works seamlessly on both iOS and Android. Beyond standard send/receive functionality, the app must include an integrated exchange so users can swap supported coins without leaving the interface, as well as a smooth in-app purchase flow for buying crypto with fiat. A key differentiator is the payment card element: users should be able to order a virtual or physical card linked to their wallet balance and spend crypto at regular merchant terminals. I already have preliminary agreements with a card-issuing partner; what I need now is the mobile application, the secure back-end, and the card-wallet linkage. Core requirements you’ll build: • Native or cross-platform apps for iOS and Android • Secure key manage...
