Function redeem 

pub fn redeem<T: Config>(
    asset_id: T::AssetId,
    amount: <<T as Config>::Fungibles as FungiblesInspect<<T as Config>::AccountId>>::Balance,
)

Swap internal for external stablecoin.

Dispatch Origin

Must be Signed by the user performing the swap.

Details

Burns amount internal from the caller minus fee (transferred to Config::FeeDestination), then transfers the resulting amount in external stablecoin from PSM to the caller. The fee is calculated using ceiling rounding (mul_ceil), ensuring the protocol never undercharges.

Parameters

• asset_id: The external stablecoin to receive (must be in ExternalAssets)
• amount: Amount of internal to redeem

Errors

• Error::UnsupportedAsset: If asset_id is not an approved external stablecoin
• Error::AllSwapsStopped: If circuit breaker is at AllDisabled
• Error::BelowMinimumSwap: If amount is below Config::MinSwapAmount
• Error::InsufficientReserve: If PSM has insufficient external stablecoin
• Error::DecimalsMismatch: If the asset’s decimals do not match the internal asset’s decimals
• Error::AmountTooSmallAfterConversion: if the conversion to the counter-asset rounds to zero; swap would transfer nothing

Events

• Event::Redeemed: Emitted on successful redemption
