Telegram's TON Wallet Rolls Out On-Chain Yield Vaults for Bitcoin, Ethereum and USDT Holders

Vault Mechanics

The product is presented as "vaults." Users deposit BTC, ETH, or USDT into Telegram's wallet interface and the assets are pushed into on-chain strategies that return variable yield. Telegram is the distribution layer. Re7 Labs appears to be the underlying strategy operator for the headline USDT product. We have not seen a published strategy contract address, a methodology breakdown, or a third-party audit in the announcement material. That absence is material, not incidental.

Variable APY is the operative term. Unlike a fixed-term lending product, the rate floats with the underlying strategy's utilization, leverage, and the market conditions of the assets deployed. The 18% figure is a current blended estimate, not a guaranteed coupon.

Where The Yield Originates

Re7-style strategies typically aggregate deposits across lending markets, basis trades, and looping positions. On a healthy day that produces double-digit APYs. On a stressed day — a stablecoin depeg, a CEX insolvency, a sudden liquidation cascade — those same positions unwind quickly and the APY compresses to zero or turns negative on the principal. The 18% is the ceiling. The floor is not disclosed.

For the BTC and ETH vaults specifically, the underlying strategy composition is not detailed in the announcement. We cannot confirm whether they use lending, perps basis, liquid staking, or some combination. "Bitcoin vault" and "Ethereum vault" as labels do not communicate the risk profile.

Context: Telegram's Revenue Stack

Telegram reported $870 million in operating revenue in H1 2025, up 65% year-over-year from $525 million. Roughly $300 million of that came from exclusivity arrangements tied to the TON token. The wallet product is therefore not a pure utility launch. It sits inside a revenue strategy that monetizes the TON user base, with yield features acting as the engagement hook. That does not make the product unsafe. It does mean the marketing incentive favors high headline APYs.

Developers have been working since 2024 to wire TON ecosystem products into Telegram's user base, with mixed results after the early tap-to-earn cycle cooled. The vault rollout is a more capital-intensive iteration of that effort.

Risk-To-Reward Verdict

High APY delivered through a custodial wallet UI, backed by an undisclosed third-party strategy operator, is a familiar attack surface. The upside is real — 18% on stablecoins is not a trivial return. The downside is the standard DeFi tail: smart contract failure, oracle manipulation, stablecoin depeg, and strategy-level insolvency. We do not yet have enough contract-level transparency to underwrite the product. Deploy only what you can write off, and only after the strategy addresses and audit reports are published.
