+Add support for custom singlePhase drops
+
+If you are using a custom drop contract, you can now set claim conditions and claim by passing the `singlePhaseDrop` option to the `setClaimConditions` and `claimTo` functions.
+
+```ts
+setClaimConditions({
+  contract,
+  phases: [
+    {
+      startTime: new Date(0),
+      maxClaimableSupply: 10n,
+    },
+  ],
+  tokenId: 0n,
+  singlePhaseDrop: true, // <--- for custom drop contracts
+});
+```
