Exchange Rate

The Accountant contract tracks the exchange rate between vault shares and the underlying asset. Equivalent to SDK’s internal getRateInQuoteWithAssetDecimals().

Contract Method

`getRateInQuoteSafe(quote)`

Returns the amount of the quote asset per 1e18 vault shares.

Parameter	Type	Description
`quote`	`address`	The token address to quote the rate in (e.g., USDC address)

Returns: uint256 rateInQuote — amount of the quote asset per one full share (1e18)

Usage

Call on the Accountant contract (vault.accountantModuleId from Vault Discovery).

For deposits (calculating minimumMint)

rate          = Accountant.getRateInQuoteSafe(depositTokenAddress)
expectedShares = (depositAmount × 1e18) / rate
minimumMint    = expectedShares × (10000 − SLIPPAGE_BPS) / 10000

For withdrawals (converting want amount to shares)

rate         = Accountant.getRateInQuoteSafe(wantAssetAddress)
sharesNeeded = (wantAmount × 1e18) / rate

The rate uses the quote asset’s decimals. For example, if quoting in USDC (6 decimals) and the rate is 1050000, that means 1 vault share ≈ 1.05 USDC.
