Keeper – Why Tonkeeper Went Multichain
Nikita Monastyrskiy is chief marketing officer at Keeper, the self-custodial wallet formerly known as Tonkeeper. He started in crypto in 2018, running bounty and Bitcointalk signature campaigns while still at university, then spent four years at a crypto marketing agency, rising from community manager to senior growth strategist. He went on to join the marketing team at Ethereum layer two Mode, helping take it from launch to exchange listings, before moving to Wallet in Telegram in 2025 as head of partner marketing. He later switched from the custodial side to the self-custodial one, joining Tonkeeper to lead its marketing.

Why you should listen
Tonkeeper built its reputation as the leading wallet on TON, and last month it gave up the name. Monastyrskiy explains why: users had stopped living on a single chain, and were juggling several apps to hold stablecoins on TRON, Bitcoin, Ethereum and assets on layer twos. The “TON” in the name tied the brand to one network, so the team dropped it and kept the rest. Keeper now supports seven networks, including Bitcoin, Ethereum, TRON and Base, and launched mobile-first, because that is where the data showed younger users transacting.
He is direct about the trade-off at the heart of self-custody. Keeper cannot access, freeze or recover user funds, and he argues that the risk people associate with self-custody comes down to how they store their recovery phrase. Keep it offline and secure, and the main danger disappears. The harder part, in his view, is psychological: when an exchange gets hacked, users have someone to blame, but with self-custody the responsibility is entirely theirs. He sees the wallet as stage one of crypto adoption, the place where someone buys their first Bitcoin, and stage two as giving those users access to everything else on-chain, from tokenized stocks and prediction markets to simpler perpetual futures trading, which he says remains too complicated for newcomers.
Looking further out, Monastyrskiy describes his ideal wallet as one users barely see: connected to an AI assistant, taking voice commands to swap or trade, with no thought given to gas or withdrawals. He thinks a supervised version, where users still sign each transaction, is about a year away, and full automation further off. He also reports a pickup in on-chain activity since May, with volumes rising again this quarter. In the hot take round, he argues that real adoption will come from everyday payments in emerging markets rather than institutions, and picks Nineteen Eighty-Four as the science fiction he fears could become reality.
