GrumBot

GrumBot is an online service for exchanging cryptocurrencies and fiat money. The published form lists XRP, DOGE and SOL against rubles.

Networks and payment methods

Transfers run over ERC20, Arbitrum, TRC20, Polygon, BEP20, Solana and Lightning. The listed ways to pay are bank cards, PayPal, Volet, Revolut, Privat24 and Monobank, which points to a customer base that uses both Russian and Ukrainian payment tools.

Timing and limits

The processing rules mention an interval of 1 to 2 minutes. This is a provision of a specific regulation and not a promise for every transaction, since bank, network and compliance delays are possible. Minimum and maximum amounts are set per currency, direction or order, and no single limit applies to the whole service. In cases defined by the rules an order can be recalculated.

Checks and refunds

Network fees are handled separately. AML/KYC procedures are published: identity data and documents may be requested, the bank card is verified, and transactions and addresses are screened for risk. Source of funds may need confirmation. A refund can depend on a compliance review and may be reduced by fees or documented costs. A referral programme is declared.
