+# Dynamic Contract 
+
+with Dynamic Contract, you can call any smartcontract. you need abi json file for the contract.  
+- create contract beforehand, prepare contract address 
+- prepare abi json file for the contract to access
+
+
+
+## Call
+this is for non modifying contract call
+
+<figure><img src="../../../.gitbook/assets/cronos-gamefi-blueprint-dynamic-contract-call.png" alt=""><figcaption></figcaption></figure>
+
+
+
+## Send
+this is for modifying contract call. it needs `DefiWalletCoreActor` to sign the transaction.

+
+
+
+## Encode
+this is for wallet-connect. it generates data which can be included in the transaction. and the transaction can be signed with wallet-connect
