Types

type Manager

type Manager struct {
	// contains filtered or unexported fields
}

Manager submits quotes to the RFQ API. TODO: should be unexported.

func (*Manager) IsProfitable

func (m *Manager) IsProfitable(parentCtx context.Context, quote reldb.QuoteRequest) (isProfitable bool, err error)

IsProfitable determines if a quote is profitable, i.e. we will not lose money on it, net of fees.

func (*Manager) ShouldProcess

func (m *Manager) ShouldProcess(parentCtx context.Context, quote reldb.QuoteRequest) (res bool, err error)

ShouldProcess determines if a quote should be processed.

func (*Manager) SubmitAllQuotes

func (m *Manager) SubmitAllQuotes(ctx context.Context) (err error)

SubmitAllQuotes submits all quotes to the RFQ API.

type QuoteInput

type QuoteInput struct {
	OriginChainID   int
	DestChainID     int
	OriginTokenAddr common.Address
	DestTokenAddr   common.Address
	OriginBalance   *big.Int
	DestBalance     *big.Int
	DestRFQAddr     string
}

QuoteInput is a wrapper struct for input arguments to generateQuote.

type Quoter

type Quoter interface {
	// SubmitAllQuotes submits all quotes to the RFQ API.
	SubmitAllQuotes(ctx context.Context) (err error)
	// ShouldProcess determines if a quote should be processed.
	// We do this by either saving all quotes in-memory, and refreshing via GetSelfQuotes() through the API
	// The first comparison is does bridge transaction OriginChainID+TokenAddr match with a quote + DestChainID+DestTokenAddr, then we look to see if we have enough amount to relay it + if the price fits our bounds (based on that the Relayer is relaying the destination token for the origin)
	// validateQuote(BridgeEvent)
	ShouldProcess(ctx context.Context, quote reldb.QuoteRequest) (bool, error)
	// IsProfitable determines if a quote is profitable, i.e. we will not lose money on it, net of fees.
	IsProfitable(ctx context.Context, quote reldb.QuoteRequest) (bool, error)
}

Quoter submits quotes to the RFQ API.

func NewQuoterManager

func NewQuoterManager(config relconfig.Config, metricsHandler metrics.Handler, inventoryManager inventory.Manager, relayerSigner signer.Signer, feePricer pricer.FeePricer, apiClient rfqAPIClient.AuthenticatedClient) (Quoter, error)

NewQuoterManager creates a new QuoterManager.
