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.
We're building a regulated real estate tokenization platform that converts institutional-grade properties into ERC-3643 security tokens with built-in ONCHAINID compliance. Our platform enables fractional ownership, secondary trading, and DeFi integration—making premium real estate investment accessible to everyone. I am looking for a talented blockchain $ smart contract developer. Tech Stack: - Blockchain: Solidity (ERC-3643 with ONCHAINID) on Arbitrum One, Hardhat - Backend: Node.js/TypeScript, Express, PostgreSQL, Redis - Frontend: React/TypeScript, ethers.js/wagmi, Tailwind - Infrastructure: AWS, Docker, GitHub Actions Blockchain Developer Responsibilities: - Design and deploy ERC-3643 smart contracts with compliance logic - Implement ONCHAINID identity and KYC whitelist integration - Coordinate external security audits and optimize gas usage - Build DeFi lending integrations (staking, yield, collateralization)
We need to connect a payment system to a high-risk site. The main requirements are the acceptance of fiat funds and the withdrawal of funds in cryptocurrency. Preferably no KYC. Only those who have had similar experience. Price is negotiable.

What needs to be done: conduct an independent expert consultation on the implementation of multisig wallets to protect the company's treasury funds, which operates with high-volume payment processing in USDT across three networks - TRON (TRC20), BNB Smart Chain (BEP20), and Ethereum (ERC20). Requirements: (1) review available market solutions and recommend the optimal one for our profile - a single custodial platform for all three networks or a combination of separate tools for EVM and TRON; (2) propose a signature architecture (e.g., 2-of-3), key distribution among roles, thresholds for quick/large payments; (3) provide recommendations for key storage (hardware wallets, HSM) and procedures in case of key loss or compromise. For whom: the team administering the company's treasury with a high volume of crypto transactions. Success criterion: a ready recommended architecture with a clear implementation plan. Requirements: practical experience in implementing multisig, specifically with TRON (not just EVM), experience with specific solutions (Safe/Gnosis, Fireblocks, BitGo, Cobo, or native TRON multisig), preferably with cases of previous implementations.
