Expert USDT Multisig Architecture Consultation Needed

Job ID: 40582626

Budget: $50 – $0 USD

Consultation on multisig architecture for USDT (TRON, BSC, Ethereum)

What needs to be done: conduct an independent expert consultation on implementing multisig wallets to protect the treasury funds of a company that processes high-volume USDT payments simultaneously across three networks - TRON (TRC20), BNB Smart Chain (BEP20), and Ethereum (ERC20).
Required: (1) provide an overview of available solutions on the market 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 across roles, and thresholds for small/large payouts; (3) provide recommendations on key storage (hardware wallets, HSM) and procedures in case of key loss or compromise.
Who it's for: the team administering the treasury of a company with a high volume of crypto transactions.
Success criteria: a ready recommended architecture with a clear implementation plan.
Requirements: practical experience implementing multisig, mandatory experience with TRON (not just EVM networks), experience with specific solutions (Safe/Gnosis, Fireblocks, BitGo, Cobo, or native TRON multisig), previous implementation case studies preferred.
