Solidity Developer Needed — Flash Loan + Collateralized Lending Integration I’m looking for an experienced Solidity/DeFi developer to build a small, focused smart-contract component that demonstrates the interaction between a flash-loan provider (Aave v3) and a collateralized lending protocol. Scope of Work I need the contract to: Obtain a flash loan for an amount supported by the available liquidity. Supply/deposit the flash-loaned assets into a specified collateralized lending protocol/pool. Borrow the maximum amount permitted by that protocol's normal collateralization rules. Handle the required transaction flow and protocol interactions correctly. The implementation should use the lending protocol's standard collateral, borrowing, repayment, and withdrawal me...

I’m putting together a “flash-style” application that lets adult learners explore core cryptocurrency concepts in a classroom setting. The aim is to keep everything simple enough for first-time students yet authentic enough that they see real-world mechanics in action. Here’s what I need the build to cover: • Data encryption built in from the ground up so students can encrypt and decrypt sample strings and immediately view the results. • Basic blockchain integration that spins up a local test chain, writes a few dummy transactions, and then visualises block creation. • A small, self-contained wallet module that can generate keys, sign test transactions, and show balances—all within the local sandbox, no live coins involved. The tool only ...

The goal is to launch a new TRC-20 cryptocurrency on the Tron network that ships with three core capabilities: native wallet support, real-time transaction tracking, and an on-chain staking mechanism. Token creation should follow current best practices for Tron smart contracts, including upgradability and pausable safeguards. Once the contract is live, I will need seamless wallet integration so holders can store, send, and receive the coin through both mobile and web extensions (TronLink, Trust Wallet, etc.). A lightweight block-explorer style dashboard or API that surfaces transfers, balances, and staking statistics in real time must accompany the launch so activity is always transparent. Staking is central to the token’s utility: users should be able to lock their balance for...

A decentralized AI compute platform designed to connect GPU providers with AI workloads through a distributed computing network. Instead of running AI workloads entirely on centralized cloud infrastructure, the platform allows independent miners to contribute GPU resources for tasks such as AI inference, model processing, fine-tuning, and other compute-intensive workloads. The system coordinates available GPU resources, assigns workloads, monitors execution, and records completed compute jobs. A blockchain-based reward mechanism is used to track contributions and provide miners with transparent incentives based on the compute they provide. The architecture separates the blockchain layer from the actual AI computation: blockchain infrastructure handles identity, job accounting, verificati...
