Setting Environment Variables
You can set these in your shell profile or pass them inline:
# In ~/.bashrc or ~/.zshrc
export ATEL_BASE_PRIVATE_KEY=0x...
export ATEL_BSC_PRIVATE_KEY=0x...
# Or inline when starting
ATEL_BASE_PRIVATE_KEY=0x... atel start 3100Directory Structure
After running atel init, the SDK creates an .atel/ directory in your current working directory:
`identity.json` contains your private key. Do not commit it to version control or share it publicly.
Updating
npm update -g @atel-ai/atel-sdkYour .atel/ directory and identity are preserved across updates.
