Yield Basis (YB), the Bitcoin-yield protocol by Curve founder Michael Egorov, is launching its token sale through a partnership with Legion and Kraken. The sale combines a merit-based presale for active users with a public first-come, first-served phase — a move many see as a test of permissionless and fair token distribution.

What Is Yield Basis?
Yield Basis aims to unlock yield on Bitcoin deposits while eliminating impermanent loss (IL). The protocol adapts Curve’s liquidity pool design with automated rebalancing, letting liquidity providers maintain full BTC exposure while earning trading fees or emissions.
YB tokenomics emphasize alignment: users must lock veYB to earn protocol fees, and LP participants must choose between accruing BTC fees or YB emissions (but not both).
Sale Structure with Legion & Kraken
The YB sale is divided into two phases. First is a merit-based presale for users with a Legion Score — allocations determined by on-chain activity, GitHub contributions, social engagement, and other criteria. Up to 20% of the total token supply is reserved for this phase.
After that, the public sale opens (on October 1) in a first-come, first-served format, available via both Kraken Launch and Legion, with immediate listing expected on Kraken.
Token Sale & Allocation Details
The public sale portion allocates 2.5% of total supply (25 million YB) at a fixed price of $0.20 per token, implying a $200 million fully diluted valuation (FDV).
Total supply is 1 billion YB — allocations include 30% for liquidity incentives, 25% to the team, 15% for ecosystem reserve, 12.1% to investors, 7.5% for Curve licensing, and 7.4% for protocol development.
Sale Cap, Refunds & Mechanics
To participate, users must pre-deposit USDC on Ethereum. During the presale, unspent funds are refunded. Legion enforces minimum/maximum purchase caps (e.g. up to $25,000) to limit concentration risk.
Because allocations in the presale are based on reputation metrics rather than pure capital, the design aims to favor builders and active contributors over whales.
Tying Into Curve & crvUSD Liquidity
Yield Basis has secured a $60 million crvUSD credit line from Curve DAO, which will seed BTC pools and anchor protocol growth through liquidity support.
This linkage aligns YB’s growth with Curve’s stablecoin ecosystem, as veCRV holders will share in protocol revenues. It deepens integration between YB and Curve’s governance mechanisms.
Risks & Community Expectations
Challenges ahead include smart contract execution, liquidity management, and investor expectations. The team must deliver on claims of impermanent loss protection under volatile conditions. Some in the community warn about possible bottlenecks if the protocol scales too fast.
Regulatory compliance is also a question mark, particularly in jurisdictions with strict token offering rules. The sale design, with merit-based access and refunds, may help address some compliance concerns.
What To Watch & Long-Term Outlook
In the coming days, key metrics to monitor include presale deposit volumes, how fast the public sale sells out, and the depth of post-listing liquidity on Kraken.
Longer term, success hinges on whether YB can attract sustained deposits, maintain real BTC yield, and maintain seamless integration with Curve’s ecosystem. If they pull it off, Yield Basis could become a flagship BTC yield protocol in DeFi.
