Good day . There is experience writing MEV bots on C# + Web3 + Solidity. The only problem is that to change the order of transactions in the block you need to be a validator. You also need your node in any case, but it is relatively difficult to break the node. The price will be discussed.

Welcome to!
Ready to help you with the implementation of the arbitration bot.
I have similar experience of implementing similar bots, and experience of blockchain development and web3, so with creating a bots there will be no problems.
I understand all your demands, but there are still a few questions that I would like to discuss with you in pp.
I look forward to your response and successful collaboration.
Good day !

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.
