I am a NodeJS developer. I have experience with crypto payment systems. Write to me, and we will discuss.
We need to connect a payment system to a high-risk site. The main requirements are the acceptance of fiat funds and the withdrawal of funds in cryptocurrency. Preferably no KYC. Only those who have had similar experience. Price is negotiable.

Hello! Connecting a payment gateway for accepting fiat and withdrawing in cryptocurrency is a completely workable task; I constantly deal with integrating payment systems and third-party APIs. We can discuss the specifics of high risk and options without KYC in private messages.

What type of high-risk direction is being discussed — gambling, forex, or something else, and what geolocation is the fiat acceptance oriented towards? This affects the choice of provider and the scheme for converting to cryptocurrency. I have experience connecting payment gateways for high-risk projects and working with crypto exchanges for fund withdrawals without unnecessary verification. First, I will analyze the available options for fiat acceptance based on your case, select the appropriate crypto provider, and set up the connection between the systems. I am ready to present the first working solution approximately 5 days after agreeing on the details.

Oleg, I understand the specifics of the high-risk niche and the limitations you face when choosing gateways. You need a reliable merchant that works with fiat and automatic conversion to crypto, while minimizing KYC requirements for your clients.
I will analyze the current conditions of providers willing to work with such projects and select options that will allow for seamless payment acceptance without unnecessary blocks. I will create a clear connection plan with minimal technical risks for your site.
What transaction volumes do you plan to process through the gateway at the start, in order to select a payment solution with adequate limits and fees?

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.
