== Deposit request
-The starting point for acquiring TBTC is generating a _deposit request_. This is
-a transaction to a smart contract on tBTC's host chain that informs the tBTC
-system that the sender account is interested in creating a TBTC deposit. The
-transaction is a signal that the sender is interested in a signing group to back
-a wallet that will receive bitcoin from a wallet the sender controls, in order
-to produce TBTC. Because signing groups are not free to create, deposit requests
-include a small bond in the host chain's native token to cover the creation of
-the signing group. The bond is refunded when a successful deposit is made to the
-generated wallet.
