supply_asset

Supply an ERC-20 token as collateral to the lending pool.

Parameters

• asset (string): ERC-20 token symbol or address (e.g. USDC, WETH)
• amount (string): Amount to supply in human-readable units (e.g. 100)
• wallet_address (string): User's wallet address

Steps

1. Call GET /api/v1/tokens?symbol={asset} to resolve the token contract address and decimals
2. Convert amount to token units: amount_raw = amount * 10^decimals
3. Call GET /api/v1/allowance?token={token_address}&owner={wallet_address}&spender=POOL to check existing approval
4. If allowance < amount_raw, call POST /api/v1/approve with body { token: token_address, amount: amount_raw, owner: wallet_address } The response contains { to, data, value }. Execute the approval transaction:

   await walletClient.sendTransaction({ to: resp.to, data: resp.data, value: resp.value })
   

5. Call POST /api/v1/supply with body { token: token_address, amount: amount_raw, wallet: wallet_address } The response contains { to, data, value }. Execute the supply transaction:

   await walletClient.sendTransaction({ to: resp.to, data: resp.data, value: resp.value })
   

6. Return a confirmation with the supplied amount and the resulting health factor

borrow_asset

Borrow an asset against the user's supplied collateral.

Parameters

• asset (string): ERC-20 token symbol or address to borrow
• amount (string): Amount to borrow in human-readable units
• wallet_address (string): User's wallet address

Steps

1. Call GET /api/v1/tokens?symbol={asset} to resolve token details
2. Call GET /api/v1/borrow-capacity?wallet={wallet_address} and verify there is sufficient collateral to cover the requested borrow amount
3. Call POST /api/v1/borrow with body { token: token_address, amount: amount_raw, wallet: wallet_address } The response contains { to, data, value }. Execute the borrow transaction:

   await walletClient.sendTransaction({ to: resp.to, data: resp.data, value: resp.value })
   

4. Return the borrowed amount and the updated health factor

get_position

Returns the user's current lending position. This is a read-only call — no transaction is executed.

Parameters

• wallet_address (string): User's wallet address

Steps

1. Call GET /api/v1/position?wallet={wallet_address}
2. Return { supply_balance, borrow_balance, health_factor, available_to_borrow }
