Constants ¶
const ( BlockCacheSize = 600 MaximumConfirmation = 99999999 MaxAsgardAddresses = 100 // EstimateAverageTxSize for BASEChain the estimate tx size is hard code to 250 here , as most of time it will spend 1 input, have 3 output EstimateAverageTxSize = 250 MaxMempoolScanPerTry = 500 )
BlockCacheSize the number of block meta that get store in storage.
const ( // SatsPervBytes it should be enough , this one will only be used if signer can't find any previous UTXO , and fee info from local storage. SatsPervBytes = 25 // MinUTXOConfirmation UTXO that has less confirmation then this will not be spent , unless it is yggdrasil MinUTXOConfirmation = 1 )

Functions ¶
func GetBech32AccountPubKey ¶
func GetBech32AccountPubKey(key *btcec.PrivateKey) (common.PubKey, error)
GetBech32AccountPubKey convert the given private key to
func IsLitecoinDaemonPostVersion19 ¶ added in v1.104.0
IsLitecoinDaemonPostVersion19 get the network information from RPC endpoint , and determine whether the LTC daemon version is after 0.19.0, since a few RPC endpoint changed after `0.19.0`, specifically sendrawtransaction
Types ¶
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
Client observes litecoin chain and allows to sign and broadcast tx
func NewClient ¶
func NewClient(thorKeys *mayaclient.Keys, cfg config.BifrostChainConfiguration, server *tssp.TssServer, bridge mayaclient.MayachainBridge, m *metrics.Metrics) (*Client, error)
NewClient generates a new Client
func (*Client) BroadcastTx ¶
BroadcastTx will broadcast the given payload to LTC chain
func (*Client) ConfirmationCountReady ¶
ConfirmationCountReady will be called by observer before send the txIn to thorchain confirmation counting is on block level , refer to https://medium.com/coinmonks/1confvalue-a-simple-pow-confirmation-rule-of-thumb-a8d9c6c483dd for detail
func (*Client) FetchMemPool ¶
FetchMemPool retrieves txs from mempool
func (*Client) GetAccount ¶
GetAccount returns account with balance for an address
func (*Client) GetAccountByAddress ¶
func (*Client) GetAddress ¶
GetAddress returns address from pubkey
func (*Client) GetBlockScannerHeight ¶ added in v1.109.0
GetBlockScannerHeight returns blockscanner height
func (*Client) GetConfig ¶
func (c *Client) GetConfig() config.BifrostChainConfiguration
GetConfig - get the chain configuration
func (*Client) GetConfirmationCount ¶
GetConfirmationCount return the number of blocks the tx need to wait before processing in BASEChain
func (*Client) GetLatestTxForVault ¶ added in v1.109.0
func (*Client) IsBlockScannerHealthy ¶
func (*Client) OnObservedTxIn ¶
OnObservedTxIn gets called from observer when we have a valid observation For litecoin chain client we want to save the utxo we can spend later to sign
func (*Client) RegisterPublicKey ¶
RegisterPublicKey register the given pubkey to litecoin wallet
func (*Client) ReportSolvency ¶
func (*Client) ShouldReportSolvency ¶
ShouldReportSolvency based on the given block height , should the client report solvency to THORNode
func (*Client) SignTx ¶
SignTx builds and signs the outbound transaction. Returns the signed transaction, a serialized checkpoint on error, and an error.
type KeySignWrapper ¶
type KeySignWrapper struct {
// contains filtered or unexported fields
}
KeySignWrapper is a wrap of private key and also tss instance it also implement the txscript.Signable interface, and will decide which method to use based on the pubkey
func NewKeySignWrapper ¶
func NewKeySignWrapper(privateKey *btcec.PrivateKey, tssKeyManager tss.ThorchainKeyManager) (*KeySignWrapper, error)
NewKeySignWrapper create a new instance of Keysign Wrapper
func (*KeySignWrapper) GetSignable ¶
func (w *KeySignWrapper) GetSignable(poolPubKey common.PubKey) txscript.Signable
GetSignable based on the given poolPubKey
type TssSignable ¶
type TssSignable struct {
// contains filtered or unexported fields
}
TssSignable is a signable implementation backed by tss
func NewTssSignable ¶
func NewTssSignable(pubKey common.PubKey, manager tss.ThorchainKeyManager) (*TssSignable, error)
NewTssSignable create a new instance of TssSignable
func (*TssSignable) GetPubKey ¶
func (ts *TssSignable) GetPubKey() *btcec.PublicKey
