+title: Migrate Fee Payment from Currency to fungible traits
+
+doc:
+ - audience: Runtime Dev
+ description: |
+ Deprecates the `CurrencyAdapter` and introduces `FungibleAdapter`
+ Deprecates `ToStakingPot` and replaces usage with `ResolveTo`
+ Updated `DealWithFees`, `ToAuthor`, `AssetsToBlockAuthor` to all use `fungible` traits
+ Updated runtime XCM Weight Traders to use `ResolveTo`
+ Updated runtime TransactionPayment pallets to use `FungibleAdapter` instead of `CurrencyAdapter`
+
+ Runtime Migration Guide:
+ - Replace usage of `CurrencyAdapter` with `FungibleAdapter`
+ - Replace usage of `ToStakingPot<Runtime>` with `ResolveTo<pallet_collator_selection::StakingPotAccountId<Runtime>, Balances>`
