I have extensive experience in developing smart contracts in Solidity. I am ready to develop the contract within 2 weeks. If interested, I am ready to discuss in more detail via private message.
✅ Technical Specification:
Development and deployment of 3 vesting smart contracts for different ERC-20 tokens
What the contract includes:
- Ability to deposit certain ERC-20 tokens and receive a fixed percentage per day for a certain period of time
- Vesting time period
- Cliff start from the moment tokens are deposited
- Ability for a person with one wallet to have an unlimited number of vesting releases
- Automatic claiming
- Admin pause and cancel for all contract functions
- Percentage parameters and vesting time should be adjustable by the admin
- Event logs for display in scanners
- Minimum and maximum transaction volume
- Interface for an external bot to call functions

Hello, my name is Vladislav, I represent a team of experienced developers with over 5 years of experience in Full-Stack and blockchain development, including deep expertise in Solana and SPL tokens.
Your task of creating and deploying vesting smart contracts fully aligns with our experience and competencies. We successfully implement projects with flexible parameter settings, automatic stamping, event logging, and an admin panel — everything you described.
We understand the importance of security, scalability, and ease of contract management, so we are ready to offer a solution that will exceed your expectations. Our team uses modern technologies Rust and TypeScript, which allows us to create reliable and efficient smart contracts.
We would be happy to discuss your project in detail and help bring it to life. We deliver what most cannot — that is why our clients trust us with the most complex and innovative tasks

Hello! I have reviewed your project and am ready to start work. I guarantee high quality and prompt execution.
What we are calculating in the project: Realized PnL, ROI, and Win Rate for cryptocurrency wallets - how profitable the wallet traded a certain token over the selected period. Based on what data: the history of on-chain transactions of the wallet (swaps, token transfers) + the market price of the token at the time of each transaction. The main data source is Moralis: two calls during the initial loading of the wallet - native ETH transfers and all ERC-20 token transfers. What we are comparing with: Nansen.io - we take it as a benchmark, comparing our calculated metrics with what Nansen shows for the same wallets over the same period. Problem: our figures significantly differ from Nansen, and we do not fully understand the rules by which some actions of the wallet should be classified for PnL purposes. We need to fix the calculation of Realized PnL, ROI, and Win Rate to match Nansen. In your application, please write: - experience with similar tasks - experience with Nansen - experience with Moralis - experience with DeFiLlama - experience with articles on crypto transactions - approximate cost and timeline for the fix
It is important to start - TODAY I need a person who has experience in writing trading bots on DEXs (needed on the BSC network) with an understanding of transaction costs, gas, etc. I want to test several trading strategies on a real trading agent I need to quickly develop an autonomous trading agent that uses the Trust Wallet and CoinMarketCap APIs to execute trades on the BNB Chain (BSC) based on 3–5 embedded strategies. Technology stack (mandatory) - Trust Wallet Agent Kit (TWAK) — for self-custodial signing and executing transactions (https://portal.trustwallet.com) - CoinMarketCap AI Agent Hub — for obtaining market data and signals (https://coinmarketcap.com/api/agent) - BNB AI Agent SDK — for quick integration (https://github.com/bnb-chain/bnbagent-sdk) Functional requirements Data (CMC AI Agent Hub) - Data retrieval via MCP or x402 (https://coinmarketcap.com/api/agent) - Use of ready-made Skills for RSI, MACD, Fear & Greed, volumes Execution (Trust Wallet Agent Kit) - Local signing of transactions — keys remain with the user (https://portal.trustwallet.com) - Autonomous mode: the agent signs and sends trades by itself - Limitations: drawdown, daily limit, stop-loss, token whitelist - Use of x402 for payment of data/computations Strategies - Implement 3–5 described strategies with the ability to switch between them - Examples: combination of funding rates + Fear & Greed, DCA based on sentiments with filters Technical requirements - Language: Python (preferred) or TypeScript/JavaScript - Tools: TWAK CLI, CMC CLI, BNB AI Agent SDK Who can take this on?
