* Naive bip39 with address reuse * Avoid address reuse in libkaspawallet * Add wallet daemon * Use daemon everywhere * Add forceOverride * Make CreateUnsignedTransaction endpoint receive amount in sompis * Collect close UTXOs * Filter out non-spendable UTXOs from selectUTXOs * Use different paths for multisig and non multisig * Fix tests to use non zero path * Fix multisig cosigner index detection * Add comments * Fix dump_unencrypted_data.go according to bip39 and bip32 * Fix wrong derivation path for multisig on wallet creation * Remove IsSynced endpoint and add validation if wallet is synced for the relevant endpoints * Rename server address to daemon address * Fix capacity for extendedPublicKeys * Use ReadBytes instead of ReadLine * Add validation when importing * Increment before using index value, and use it as is * Save keys file exactly where needed * Use %+v printErrorAndExit * Remove redundant consts * Rnemae collectCloseUTXOs and collectFarUTXOs * Move typedefs around * Add comment to addressesToQuery * Update collectUTXOsFromRecentAddresses comment about locks * Split collectUTXOs to small functions * Add sanity check * Add addEntryToUTXOSet function * Change validateIsSynced to isSynced * Simplify createKeyPairsFromFunction logic * Rename .Sync() to .Save() * Fix typo * Create bip39BitSize const * Add consts to purposes * Add multisig check for 'send' * Rename updatedPSTxBytes to partiallySignedTransaction * Change collectUTXOsFromFarAddresses's comment * Use setters for last used indexes * Don't use the pstx acronym * Fix SetPath * Remove spaces when reading lines * Fix walletserver to daemonaddress * Fix isUTXOSpendable to use DAA score Co-authored-by: Svarog <feanorr@gmail.com>
