Authorize a spend.
Wallet software helps construct transactions; signing keys authorize the spending of eligible outputs. A wallet balance is not a balance on this website.
NETWORK / FIRST PRINCIPLES
Understand the network.
Then the services around it.
Bitcoin combines transaction rules, a distributed ledger and a mechanism for agreeing which valid transactions become part of its history.
Check the rules.
Validating nodes check transactions and blocks against the rules they enforce. Mining and validation are different roles.
Build shared history.
Miners propose blocks through proof of work. Confirmation policies determine how a business treats settlement risk.

A payment is also
an operating process.
Price conversion, transaction detection, confirmation handling, refunds and reconciliation all need explicit policies. Network fees vary; no live fee estimate is supplied here.
