Context, problem, and Tetris DAO mission

Crypto assets, especially stablecoins, have become an everyday tool for investment and settlement. Two systemic bottlenecks remain: (1) fiat-RUB on-ramp/off-ramp into the crypto world, and (2) higher client trust in stablecoin buy/sell processes when dealing with centralized counterparties.

Tetris DAO builds the RUBT ecosystem where ruble on-ramp/off-ramp aligns with regulation, and “external” centralized counterparty risks are reduced through DeFi mechanics (including atomic swaps).

What makes this possible:

• Fiat-RUB on-ramp/off-ramp with settlement in rubles through regulated partner infrastructure;

• Stronger legal protection because the collateral base and settlement perimeter are localized;

• Reduced “external” centralized counterparty risk because key exchanges move into DeFi and become atomic;

• Better speed and cost because RUBT is a native on-chain asset with market liquidity instead of manual routes.

2.1. Fiat RUB on-ramp/off-ramp via regulated partner channels

Partner infrastructure operates in a regulated perimeter under supervision: Execution Platforms perform user and payment checks, and procedures for admitting the Digital Right under applicable regulation, including KYC and AML.

Settlement is localized: the Claim is settleable only (i) in RUB, (ii) on an Execution Platform, and (iii) via a request to the Agent; settlement in another currency/outside partner Execution Platforms is not provided.

The operational scenario is transparent: using Execution Platform functionality, a User—holder of RUBT—submits a request to the Settlement Agent to buy/sell RUBT on the Execution Platform; the Settlement Agent accepts and executes the request.

2.2. Protection is ensured by localizing the settlement base and Reserves

Reserves for buyback are formed and maintained in rubles on bank accounts:

• L1 (bank accounts, T+0),

• L2 (bank accounts),

• L3 (highly liquid Russian government securities)— as collateral for the buyback mechanism 1 RUBT = 1 RUB.

Holders understand what they own: holders do not receive property rights to the Reserves and do not become participants in a fund; they hold a Monetary Claim of 1 RUB per 1 RUBT.

Jurisdictional certainty for disputes and settlement: disputes regarding RUBT and/or buyback procedure are heard in courts at the claimant’s choice, while not subject to consideration in courts of unfriendly states and/or jurisdictions unfriendly to the claimant’s place of incorporation.

2.3. Centralized counterparty risks fall because exchange moves to DeFi

The key “physics” of DeFi is atomic execution: a DEX swap is a single transaction that either fully executes or does not execute at all, removing the typical risk “I already paid, but I will receive the return asset later / not at all.”

Reliance on an external counterparty’s discretion is reduced: instead of arrangements with an external centralized counterparty, the user relies on protocol rules and network finality.

This matters especially for ruble routes: the second friction (external centralized counterparty) moves from the center of the process to the periphery, in favor of reproducible on-chain routes.

2.4. Speed and total cost improve because RUBT is a native on-chain ruble with market liquidity

RUBT is a standard ERC-20 token on Ethereum. This makes it compatible with wallets, bridges, and protocols and enables 24/7 on-chain operations.

The ecosystem’s goal is market properties of the ruble: permissionless on-chain availability, predictable liquidity against major crypto assets, and compatibility with Digital Rights infrastructure.

Practical effect: fewer unnecessary conversions and manual steps → lower total spreads/fees and lower cost of error; price and settlement become market-driven rather than “by agreement.”

Mission: Tetris DAO’s mission is to build sustainable infrastructure for RUBT circulation: RUBT as a Digital Right and protocol token, deep on-chain pools, partnerships, and an institution-friendly model.
