BTCD

BTCD is an Ethereum token that holds a 50/50 mix of BTC and dollar exposure, rebalanced internally between vaults as BTC moves, with a staked version sBTCD that carries the yield. Role-gated allocators and internal RFQ execution can change exposure among Yield Basis, Morpho, Aave, IPOR, Uniswap and productive collateral after a holder deposits. That continuing portfolio discretion, not its approximately $1.67M size across Ethereum and Arbitrum on 2026-08-15, is the fundamental mandate conflict. The version-1 delegated-allocation dossier controls and rejects the aggregate receipt at zero.

Review triggers: events that reopen the verdict
• Enforces an immutable or client-specific allowlist and per-venue limits covering only mandate-approved assets and strategies, with holdings, debt, RFQ execution and realized losses independently observable
• Demonstrates a proposed-size stressed BTCD and sBTCD redemption through every active strategy without new subscriptions or discretionary venue substitution

Watched nightly: a warning on its venues or files, or a cited document that changes, reopens the memo. The first confirmation is due 2026-11-15.

The research file

Mechanism applicability

BTCD is an onchain token representing a portfolio targeting 50% BTC and 50% stablecoin exposure. Price-band rebalancing buys or sells BTC exposure to restore that target; productive BTC and dollar assets plus the rebalancing premium generate excess collateral distributed through sBTCD. Role-gated vault allocators choose among approved assets and external strategies after deposit, so holders cannot enforce the advisor’s venue-by-venue allowlist and caps. That is exactly the continuing allocation authority addressed by the shared delegated-allocation dossier.

Current observation and perimeter

The DefiLlama protocol API read on 2026-08-15 classified BTCD as Yield and reported approximately $1.67M, almost entirely on Ethereum with a small Arbitrum balance. Current BTCD materials describe live mint, redeem and stake functions, a USD Vault launched in April 2026, and active Morpho and IPOR integrations. The registry now includes Arbitrum rather than describing the product as Ethereum-only.

Control and exit applicability

BTCD portfolio contracts and role-gated vault allocators choose approved assets, execute internal RFQ rebalances and use external venues including Yield Basis, Morpho, Aave, IPOR and Uniswap. Base BTCD can be redeemed onchain for USDC at current portfolio value; sBTCD first depends on its staking conversion, while leveraged USD Vault exits atomically unwind wBTC debt and retire sBTCD. Underlying depeg, lending, leverage, oracle, RFQ and market-liquidity risks can still impair realized value.

Why the class rule decides

BTCD’s 50/50 target does not make the underlying venues fixed: allocators, portfolio contracts and RFQ execution determine the live assets, debts and counterparties. That look-through can change without a holder transaction and can include venues or leverage outside an advisor-approved list. The shared v1 delegated-allocation dossier therefore decides regardless of size. Reopen only if immutable or client-specific controls enforce approved venues and caps, live holdings and debt are independently observable, and a proposed-size BTCD and sBTCD exit succeeds under stress; compare against separately held BTC and cash positions with explicit limits.

Class rule

The delegated allocation class is outside the approved structures, so every protocol in it is not approved until the rule changes. The rule is about the structure, not an adverse finding about this protocol, and it is not a client instruction. The events that would reopen it are listed with the memo.

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

Inherited controls

The research above describes the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The layer with the most administrative power sets the position’s effective control; that describes control, not quality or suitability.
