Executive Summary

The market can already move value within minutes and combine assets like building blocks, but this barely works with the ruble. On the one hand, people and businesses need a clear, compliant fiat-RUB on-ramp and off-ramp for working with stablecoins—within a legal framework, with checks and settlements. On the other hand, they need fast, low-cost conversion without a long chain of intermediaries and without the typical risk of “I have already delivered the asset while the counterparty is still deciding.”

The core question is: how can the ruble become a full participant in the crypto economy without turning the entire route into a grey zone and manual arrangements? The answer is the Tetris ecosystem and RUBT.

Key advantages of the ecosystem:

• A legally permitted way to buy and sell stablecoins for rubles within the scope of Execution Platforms;

• Conversion through atomic swaps in DeFi;

• Deep liquidity driven by incentives in TETRIS tokens;

• Trust through verified Reserves;

• veTETRIS as the key that gives partners influence and better commercial terms in the ecosystem.

1.1. Fiat RUB on-ramp/off-ramp becomes compliant

The main pain point of ruble routes is finding an optimal and predictable way to buy stablecoins for rubles. In the Tetris architecture, this is solved by keeping RUB settlements not inside a DAO and not “off to the side,” but within the infrastructure of Execution Platforms.

An Execution Platform is partner infrastructure that is legally entitled to work with Digital Rights, including settlements in fiat rubles. It performs KYC/AML and other checks under its rules and applicable law, ensuring transaction reliability.

RUBT is a Digital Right that selected partners are legally entitled to handle. RUBT evidences a Monetary Claim of 1 RUB per 1 RUBT against Tetris DAO LLC, acting as the Issuer. Settlement is possible in rubles on a selected Execution Platform through a request to the Settlement Agent. This is the meaning of compliance: rubles circulate only where a proper legal regime and procedures exist.

1.2. Conversion stops being centralized: exchange moves to atomic on-chain swaps

The second systemic pain point is conversion. In classic ruble routes it often relies on a chain of centralized counterparties and manual execution—many points of failure, complex checks, and an opaque total cost.

The RUBT model separates processes: settlement of the Claim is performed in RUB through an Execution Platform, while exchange of RUBT into other crypto assets happens on-chain through decentralized exchanges, where execution is atomic: either the whole swap executes, or it does not happen—removing the typical risk of “the asset is already gone while the return leg has not arrived.”

As a result, total route cost becomes a function of pool depth, fees, and slippage—not the number of intermediary links.

1.3. Deep liquidity is built via TETRIS and makes swaps institution-grade

The DAO deliberately grows liquidity in key RUBT pairs by distributing rewards in TETRIS to those who create real depth: liquidity providers and partners who bring volume. This happens via:

• a Points program (points for measurable actions—liquidity, volume, retention, flow quality—later converted into rewards); and

• targeted incentives for specific pools/integrations when capacity must grow quickly.

The deeper the pool, the lower the slippage and the more accurate the price for large amounts, making swaps institution-grade for recurring operations. Volume then reinforces the system: more liquidity → better price and lower costs → more swaps → stronger incentives for partners to expand liquidity and distribution.

1.4. Trust is built through ≥1:1 Reserves and verified Proof-of-Reserves

On the side of the Settlement Agent—the Issuer’s representative—an obligation is закреплено on the Execution Platform to maintain RUB Reserves at no less than 1:1 and to provide Proof-of-Reserves with predictable frequency and methodology.

Reserves are formed from cash balances on accounts, highly liquid OFZ (Russian federal bonds), and similar instruments. All Reserves are held in rubles in the country of incorporation of the Execution Platform, which is critical for risk management and trust.

1.5. veTETRIS is the access key for institutions and the community

TETRIS/veTETRIS is not about an abstract “token price.” It controls access to the fee economics of RUBT flows.

The model targets payment and infrastructure partners: holding veTETRIS gives them a rebate from swap fees on RUBT (for their own and their clients’ operations). This makes RUBT a margin source for partners’ conversion and payments business and creates a direct incentive to bring and retain flow inside the ecosystem.

For the crypto community, a mechanism is provided to delegate veTETRIS to large holders in exchange for a share of rebates. Partner terms depend on the partner’s veTETRIS ranking relative to others, so large players must maintain and expand their veTETRIS position to keep advantages.

Finally, veTETRIS gives influence over protocol parameters: the rebate scale, pool selection, POL management, and treasury policy—i.e., the factors that determine spreads, capacity, and predictability of conversion for large flows.
