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.
