Networks
9 networks, 19 assets, one API
Every payment names its network and asset, like {"network": "tron", "asset": "USDT"}. This list comes straight from the engine's catalog, so it is always the one the API uses.

How confirmations work
Depth on Bitcoin
Larger amounts wait for more blocks. The tier comes from the larger of the transfer and the payment, so splitting a payment into small transfers can't lower it.
Finality elsewhere
The other networks credit a deposit at their finalized block, so a credit never rests on a block that can still disappear. Base credits at the safe head instead, once the block's data is posted to Ethereum.
Reorganizations
If the chain drops a deposit, the payment returns to waiting and any credit is reversed, and your server gets a webhook for each change.
