- Add ``crypto:payment:fee`` form to represent the payer and value of a transaction fee (the ``crypto:currency:transaction:fee`` prop remains the shorthand total). - Add ``crypto:smart:effect:freeze`` effect form for issuer blocklist freeze/unfreeze actions. - Add ``crypto:smart:effect:seize`` effect form for issuer destruction of the tokens held by an address.

…orms - Add ``crypto:smart:effect:swaptokens`` effect form to represent a DEX/AMM swap as a distinct fact (a swap is not derivable from the individual token transfers). A null ``:sent:contract`` / ``:received:contract`` indicates a native currency leg. - Add ``crypto:currency:bridge:swap`` form to represent a cross-chain swap which links the origin and destination transactions on different chains, enabling pivots between the two legs. Destination properties other than the transaction are optional since a matched swap may lack destination details.
