Constants

const (
	ReadinessEthSyncing    readiness.Component = "ethSyncing"
	ReadinessSolanaSyncing readiness.Component = "solanaSyncing"
	ReadinessTerraSyncing  readiness.Component = "terraSyncing"
)

const MaxGuardianCount = 19

Matching constants:

• MAX_LEN_GUARDIAN_KEYS in Solana contract (limited by transaction size - 19 is the maximum amount possible)

The Eth and Terra contracts do not specify a maximum number and support more than that, but presumably, chain-specific transaction size limits will apply at some point (untested).

Types

type BridgeWatcher

type BridgeWatcher interface {
	WatchLockups(events chan *ChainLock) error
}

type ChainLock

type ChainLock struct {
	TxHash    common.Hash // TODO: rename to identifier? on Solana, this isn't actually the tx hash
	Timestamp time.Time

	Nonce uint32

	SourceAddress vaa.Address
	TargetAddress vaa.Address

	SourceChain vaa.ChainID
	TargetChain vaa.ChainID

	TokenChain    vaa.ChainID
	TokenAddress  vaa.Address
	TokenDecimals uint8

	Amount *big.Int
}

type GuardianSet

type GuardianSet struct {
	// Guardian's public key hashes truncated by the ETH standard hashing mechanism (20 bytes).
	Keys []common.Address
	// On-chain set index
	Index uint32
}

func (*GuardianSet) KeyIndex

func (g *GuardianSet) KeyIndex(addr common.Address) (int, bool)

Get a given address index from the guardian set. Returns (-1, false) if the address wasn't found and (addr, true) otherwise.

func (*GuardianSet) KeysAsHexStrings

func (g *GuardianSet) KeysAsHexStrings() []string
