+The parser returns a `PumpFunTransaction` object (or an array of `PumpFunTransaction` objects if `parseMultiple` is called):

+interface PumpFunTransaction extends BaseParsedTransaction<PumpFunAction> {
+    actions: PumpFunAction[];
+}
+
+type TradeInfo = {
+    solAmount: bigint;    // Amount of SOL involved in the trade
+    tokenAmount: bigint;  // Amount of tokens involved in the trade
+    tokenMint: PublicKey; // Public key of the token mint

+    trader: PublicKey;    // Public key of the trader
+};
+
+interface PumpFunAction extends BaseParsedAction {
+    info: TradeInfo;
+}
+```
+
+Each `PumpFunTransaction` contains an array of `PumpFunAction`s, representing the trades made in the transaction. The `TradeInfo` provides detailed information about each trade, including the amounts of SOL and tokens involved, and relevant public keys.
