Confidential DeFi

Confidential DeFi — two Host surfaces, one admission model (whitelist · boundCallHash · conservation · atomicity).

Surface	Settlement object	Kohaku extra	Venues (MVP scope)
Transient	fixed-value asset note	prepareDefiAdapt	Uniswap V3 swap · Aave supply/withdraw
Position	dynamic-value position deed	prepareDefiPosition	Aave open · repay · close

Eventual Host loop (wallet-submit MVP)

prepareDefiAdapt | prepareDefiPosition
  → broadcastPrivateOperation
  → waitForTransactionReceipt
  → balance([assetId])

Sandbox sketches teach that loop as shape literacy. The package returns TenebraeKohakuNotImplementedError until a venue recipe is enabled per chain. Docs Prepare / Execute are orientation — not live venue proof.

plugin.prepareDefiAdapt(args: {
  recipeId: string; // 'uniswap_v3_swap' | 'aave_v3_supply' | 'aave_v3_withdraw'
  input: AssetAmount;
  minOutput?: AssetAmount;
  venueParams?: Record<string, unknown>;
}): Promise<PrivateOperation>

plugin.prepareDefiPosition(args: {
  recipeId: string; // 'open_position' | 'repay_position' | 'close_position'
  legs: AssetAmount[];
  venueParams?: Record<string, unknown>;
}): Promise<PrivateOperation>

Method	Intent	Maturity
prepareDefiAdapt	Transient adapt (swap · Aave supply/withdraw)	Interface on spine — NotImplemented until enablement
prepareDefiPosition	Open / adjust / close position	Same honesty
