Bitcoin is handled as Bitcoin
Bitcoin uses its own UTXO transaction model. VaultFi does not treat BTC transactions as though they were Ethereum-style account transactions.
That chain-specific handling is important for fee estimation, spend construction and transaction confirmation.
Core wallet model
The VaultFi core wallet is designed around customer-authorized non-custodial signing rather than a conventional exchange balance.
Multichain without hiding Bitcoin
Users can manage Bitcoin alongside other supported blockchain families while the underlying chain identity remains visible.
