+# ISigner Interface
+
+A basic interface that each signer must implement.
+It includes methods for signing messages, verifying signatures, and encrypting/decrypting data.
+
+
+```typescript
+interface ISigner {
+  // Core signing functionality
+  sign: (event: StampedEvent) => Promise<SignedEvent>
+  getPubkey: () => Promise<string>
+
+  // Encryption capabilities
+  nip04: {
+    encrypt: (pubkey: string, message: string) => Promise<string>
+    decrypt: (pubkey: string, message: string) => Promise<string>
+  }
+  nip44: {
+    encrypt: (pubkey: string, message: string) => Promise<string>
+    decrypt: (pubkey: string, message: string) => Promise<string>
+  }
+}
+```
