Description

Adds optional paymaster config to CdpSmartWalletProvider and corresponding chatbot and next template

Tests

Chatbot: typescript/examples/langchain-smart-wallet-chatbot/chatbot.ts
Network: Base mainnet
Setup: Funded with 0.05 USDC, no ETH
Prompt: wallet info
-------------------
Wallet Details:
- Provider: cdp_smart_wallet_provider
- Address: 0x5b246593DfCD2f462490E49A16FF4Df106640b02
- Network:
* Protocol Family: evm
* Network ID: base-mainnet
* Chain ID: 8453
- Native Balance: 0 WEI
-------------------
You are currently connected to the Base Mainnet with the wallet address **0x5b246593DfCD2f462490E49A16FF4Df106640b02**. Your native balance is 0 WEI. If you need any funds, please let me know!
-------------------
Prompt: check usdc 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 balance
-------------------
Balance of 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 is 0.05
-------------------
The balance of USDC (contract address **0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913**) in your wallet is **0.05 USDC**. If you need further assistance, let me know!
-------------------
Prompt: send 0.01 usdc to 0xf2d4580ADfe8E012f5550322706d62DF11fDBE21 -------------------
Error transferring the asset: SyntaxError: Cannot convert 0.01 to a BigInt
-------------------
It seems there was an issue with the amount format for the transfer. The amount needs to be specified in the smallest unit for USDC. Since 1 USDC = 10^6 units, I'll convert 0.01 USDC to the smallest unit, which is 10000.
I'll proceed to send 10000 USDC units (0.01 USDC) to the specified address. -------------------
Transferred 10000 of 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 to 0xf2d4580ADfe8E012f5550322706d62DF11fDBE21.
Transaction hash for the transfer: 0xf1d03399fb89fe126885daaac889e752b2f9aee24f2ec4074f5357be4062f2c8
-------------------
I have successfully transferred **0.01 USDC** (10000 units) to the address **0xf2d4580ADfe8E012f5550322706d62DF11fDBE21**. The transaction hash for this transfer is: **0xf1d03399fb89fe126885daaac889e752b2f9aee24f2ec4074f5357be4062f2c8**.

Description
Adds optional paymaster config to CdpSmartWalletProvider and corresponding chatbot and next template
Tests
Chatbot: typescript/examples/langchain-smart-wallet-chatbot/chatbot.ts
Network: Base mainnet
Setup: Funded with 0.05 USDC, no ETH
Prompt: wallet info
-------------------
Wallet Details:
- Provider: cdp_smart_wallet_provider
- Address: 0x5b246593DfCD2f462490E49A16FF4Df106640b02
- Network:
* Protocol Family: evm
* Network ID: base-mainnet
* Chain ID: 8453
- Native Balance: 0 WEI
-------------------
You are currently connected to the Base Mainnet with the wallet address **0x5b246593DfCD2f462490E49A16FF4Df106640b02**. Your native balance is 0 WEI. If you need any funds, please let me know!
-------------------
Prompt: check usdc 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 balance
-------------------
Balance of 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 is 0.05
-------------------
The balance of USDC (contract address **0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913**) in your wallet is **0.05 USDC**. If you need further assistance, let me know!
-------------------
Prompt: send 0.01 usdc to 0xf2d4580ADfe8E012f5550322706d62DF11fDBE21 -------------------
Error transferring the asset: SyntaxError: Cannot convert 0.01 to a BigInt
-------------------
It seems there was an issue with the amount format for the transfer. The amount needs to be specified in the smallest unit for USDC. Since 1 USDC = 10^6 units, I'll convert 0.01 USDC to the smallest unit, which is 10000.
I'll proceed to send 10000 USDC units (0.01 USDC) to the specified address. -------------------
Transferred 10000 of 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 to 0xf2d4580ADfe8E012f5550322706d62DF11fDBE21.

Description
Adds optional paymaster config to CdpSmartWalletProvider and corresponding chatbot and next template
Tests
Chatbot: typescript/examples/langchain-smart-wallet-chatbot/chatbot.ts
Network: Base mainnet
Setup: Funded with 0.05 USDC, no ETH
Prompt: wallet info
-------------------
Wallet Details:
- Provider: cdp_smart_wallet_provider
- Address: 0x5b246593DfCD2f462490E49A16FF4Df106640b02
- Network:
* Protocol Family: evm
* Network ID: base-mainnet
* Chain ID: 8453
- Native Balance: 0 WEI
-------------------
You are currently connected to the Base Mainnet with the wallet address **0x5b246593DfCD2f462490E49A16FF4Df106640b02**. Your native balance is 0 WEI. If you need any funds, please let me know!
-------------------
Prompt: check usdc 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 balance
-------------------
Balance of 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 is 0.05
-------------------
The balance of USDC (contract address **0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913**) in your wallet is **0.05 USDC**. If you need further assistance, let me know!
-------------------
Prompt: send 0.01 usdc to 0xf2d4580ADfe8E012f5550322706d62DF11fDBE21 -------------------
Error transferring the asset: SyntaxError: Cannot convert 0.01 to a BigInt
-------------------
It seems there was an issue with the amount format for the transfer. The amount needs to be specified in the smallest unit for USDC. Since 1 USDC = 10^6 units, I'll convert 0.01 USDC to the smallest unit, which is 10000.
I'll proceed to send 10000 USDC units (0.01 USDC) to the specified address. -------------------
Transferred 10000 of 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 to 0xf2d4580ADfe8E012f5550322706d62DF11fDBE21.
Transaction hash for the transfer: 0xf1d03399fb89fe126885daaac889e752b2f9aee24f2ec4074f5357be4062f2c8
-------------------
I have successfully transferred **0.01 USDC** (10000 units) to the address **0xf2d4580ADfe8E012f5550322706d62DF11fDBE21**. The transaction hash for this transfer is: **0xf1d03399fb89fe126885daaac889e752b2f9aee24f2ec4074f5357be4062f2c8**.
