This is not a basic betting application. The objective is to build a mathematically sound, automated, liquidity-backed on-chain betting system that functions independently and does not require manual...

The UI should feel crisp, animated and intuitive—think dark mode by default, lightweight micro-interactions and fast page transitions, all responsive down to phone portrait. I will provide brand colours and typography; you handle Figma de...

I want to launch my own central blockchain token and pair it with a fully self-hosted wallet that I can control end-to-end. The exact standard is still flexible—ERC-20, BEP-20, or even another proven framework—so I’m looking for guidance on which route best suits long-term scalability and selfhosted network. Whatever we choose, the smart contract must be clean, secure, and verifiable on-chain. Alongside the token, I need a wallet application that lets users: • send and receive the new token as well as native chain currency • view complete transaction history (confirmed and pending) • import an existing wallet via mnemonic, JSON, or private key I will host the wallet myself, so please architect it to run on my own server without third-party depende...
