## Accuracy and consent

Use each guide's stated release/version boundary. An identity key is not a traditional BSV address. Exchange withdrawals through Mountaintops require an address-receipt step and an import step. Do not invent a fiat purchase facility. Check transaction state before retrying a spend. Never request recovery material or bypass wallet consent. See the [support and AI guide](https://docs.projectbabbage.com/docs/metanet-client/agents).
