Deposit Pool Inventory

Before the Maker SDK can fill swaps, your maker_pool needs token inventory. Your pool is the counterparty in every swap you win — it sends token_out to the taker and receives token_in from the taker.

Why does the pool hold inventory?

Atomic on-chain settlement requires the pool to already have the output tokens at the time the transaction executes. There is no flash-loan or JIT liquidity — the pool holds a real pre-funded balance. This guarantees that any accepted quote can always be settled.

How to deposit

Deposits are done from the dashboard, not a script. Go to /maker → Inventory, enter a USDC or EURC amount, and click Deposit. Each token is a 2-transaction flow that Freighter walks you through:

TX 1 — approve   (token.approve → your pool)
TX 2 — deposit   (pool.deposit moves tokens into the pool)
