Supply collateral through the controller in a few steps.

​
Call the controller

governance owns admin and timelocks parameter changes. controller is the user entrypoint. One LiquidityPool holds all assets. Lending calls go to the controller, not the pool.

​
Prerequisites

RequirementDetail
Funded accountA Stellar account with XLM for fees.
Controller addressThe single entrypoint. See Addresses.

​
Supply collateral

Supplying with account_id = 0 creates a new account and returns its id. Stellar CLI (testnet example): 
stellar contract invoke \
  --id <controller> \
  --source-account your-account \
  --network testnet \
  -- supply \
  --caller YOUR_ADDRESS \
  --account_id 0 \
  --spoke_id 1 \
  --assets '[["<asset-address>", "<amount>"]]'
The call returns the new account id.

​
Check your position

stellar contract invoke --id <controller> --network testnet \
  -- health_factor --account_id <id>
A value of i128::MAX (or well above 1e18) means the account has no debt and is healthy for most actions.

​
What just happened

You created a cross-asset account. The tokens live in the single central pool. The controller now tracks your supply as collateral that can back future borrows, subject to the market’s risk parameters.
