> В вас буде тісна взаємодія з людиною по фронтенду та бекенду
Якщо є така людина, тоді навіщо хтось ще ?
Людина не розуміється в Блокчейні. В АПІ/SDK Юнісвапа свої складнощі. А людина з фронту це більш по візуалу, а с беку по розміщенню на сервері
эти api нечем не отличаются от других api, просто поменяйте себе человека. p.s. имею спред парсер по декс\мекс ценам.
Начнем с простого, вы предоставляете свои api key и полный доступ к проекту?

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.
