## Asset Transaction Payment Pallet
|
|
|
|
This pallet allows runtimes that include it to pay for transactions in assets other than the
|
|
native token of the chain.
|
|
|
|
### Overview
|
|
It does this by extending transactions to include an optional `AssetId` that specifies the asset
|
|
to be used for payment (defaulting to the native token on `None`). It expects an
|
|
[`OnChargeAssetTransaction`] implementation analogously to [`pallet-transaction-payment`]. The
|
|
included [`FungiblesAdapter`] (implementing [`OnChargeAssetTransaction`]) determines the fee
|
|
amount by converting the fee calculated by [`pallet-transaction-payment`] into the desired
|
|
asset.
|
|
|
|
### Integration
|
|
This pallet wraps FRAME's transaction payment pallet and functions as a replacement. This means
|
|
you should include both pallets in your `construct_runtime` macro, but only include this
|
|
pallet's [`SignedExtension`] ([`ChargeAssetTxPayment`]).
