Hello! As per your project post, you’re looking to build a Base-layer application with Solidity smart contracts, including an ERC-20 token, that integrates directly with Coinbase and Base APIs. The goal is to deliver fully audited contracts, automated on-chain/off-chain transaction triggers, and a REST/GraphQL service layer that allows seamless front-end interaction without manual wallet operations. My focus will be on delivering a secure, production-ready blockchain solution, featuring: ERC-20 token and supporting contract logic deployed on Base, automated transaction handling via on-chain events or off-chain triggers, integration with Coinbase/Base APIs for wallet and transaction management, a REST/GraphQL service layer for front-end consumption, comprehensive end-to-end testing using Hardhat or Foundry, and deployment scripts with clear run-books for testnet and main-net pushes. I specialize in Solidity development, blockchain architecture, Base/Coinbase integrations, automated on-chain workflows, and production-grade deployment strategies. My focus will be on building a reliable, secure, and maintainable solution that supports your token ecosystem and front-end requirements. Let’s connect to review your contract logic, automation triggers, and preferred deployment pipeline so we can define milestones and main-net launch readiness. Best regards, Nikita Gupta.

I'm Iosif Peterfi, 15+ years... This is my speciality: End-to-end crypto platform integration that brings production-ready token contracts together with automated on-chain/off-chain workflows and a service layer that talks to Coinbase and Base APIs. You need: fully-audited Solidity contracts (token + supporting logic) deployed on Base; automated transaction module wired to Coinbase/Base endpoints; REST/GraphQL service layer for your front-end; end-to-end test suite; deployment scripts and clear run-books for testnet and main-net pushes. My approach: I'll deliver these artifacts with a focus on risk reduction and a smooth production rollout. Clear milestones cover architecture alignment, contract audit finish, testnet deployment, API integration testing, and mainnet launch. The outcome is a reliable token on Base, automated transfers, and a front-end that users can call without manual steps. Last quarter I helped a fintech client deploy a loyalty token on a major platform. Automated transfers launched on mainnet with near-zero downtime and a notably faster settlement flow. Let's chat - I can walk you through my approach in 15 minutes.

@temoberishvili

Hello, This is a serious build, and it’s clear you’re aiming for a production-grade system, not just contracts. I’ve worked on Solidity-based systems with ERC-20 tokens, automation flows, and API service layers connecting on-chain logic with off-chain triggers. I can support you end-to-end — from architecture to Base mainnet deployment — with a strong focus on security, reliability, and automation. I’ll design clean, modular contracts (token + logic), implement event-driven automation (keepers/webhooks), and build a robust REST/GraphQL layer for seamless front-end interaction. Testing will be comprehensive using Hardhat/Foundry, including edge cases and failure scenarios. You’ll also get clear deployment scripts and runbooks for smooth testnet → mainnet transition. Security and audit-readiness will be prioritized from day one, not as an afterthought.
