Self-custody: the key is the ownership
You will be able to explain what holding your own keys changes, what it costs you, and how to stop trusting the node that answers your wallet.
What custody means
Whoever can sign, owns.
On this chain there is no account a company keeps for you and no register of names beside the coins. An output can be spent by whoever produces a valid signature for it, and by nobody else. Holding the key is not a way of reaching your money; it is the only form ownership takes here, which is why every lesson about wallets turns out to be a lesson about keys.
What nobody can do
No freeze, no reversal, no confiscation, in either direction.
The rules that enclose the protocol refuse, by name, any change that alters a balance, confiscates funds, rewrites the supply or edits genesis, and those refusals are tested in the code. That protects you from anyone who might want to seize what you hold. It also means nobody can undo a payment sent to the wrong address or recover coins whose keys are gone. The protection and the risk are the same rule.
The node you trust
Every number your wallet shows came from a node.
A wallet does not read the chain by itself: it asks a node and believes the answer. The public endpoints are convenient, and they are still somebody else's machine. VigiWallet lets you replace them: in its settings, point the network at your own node's RPC address, test it, and read the height, the peer count and whether mainnet is locked straight from your own hardware. A key you hold and a chain you read yourself are two halves of the same independence.
What a custodian gives you
A balance somebody holds for you is a promise, not a coin.
If a platform holds the keys, what you own is a claim against that platform, worth exactly as much as its solvency, its honesty and its willingness to let you withdraw. That can be a reasonable trade for small amounts over short periods. It is not the same thing as holding VIGI, and the difference is usually discovered on the day withdrawals stop.
In short
- Here, ownership is the ability to sign: there is no account behind the key.
- Nobody can freeze, reverse or confiscate an output, and nobody can recover one either.
- Point your wallet at your own node and read the chain from your own hardware.
- Coins held by a platform are a claim on that platform, not coins you hold.
