Description

Python equivalent of #835:

  • Fixed unit issues in native/erc20 balance/transfer actions
  • Added new action to retrieve commonly used token addresses by symbol
  • added guardrails for erc20 transfers to prevent loss of funds by sending to token contracts
  • added optional address arg (default to wallet address) to get_balance erc20 action

Python equivalent of #853:

  • added guardrails for erc20 transfers to prevent loss of funds by sending to token contracts
  • added optional address arg (default to wallet address) to get_balance erc20 action

Description
Python equivalent of #835:
  • Fixed unit issues in native/erc20 balance/transfer actions
  • Added new action to retrieve commonly used token addresses by symbol
  • added guardrails for erc20 transfers to prevent loss of funds by sending to token contracts
  • added optional address arg (default to wallet address) to get_balance erc20 action
Python equivalent of #853:
