node/zetaclient/chains/ton/observer/outbound.go

Line 205 in 6884a34

func (ob *Observer) postVoteOutbound(

const (
    outboundGasUsed     = 0 // should be taken from tx data
    outboundGasPrice    = 0 // should be taken from on-chain (rarely changes)
    outboundGasLimit    = 0 // should be consts from gw contract
    outboundBlockHeight = 0 // it's okay to have zero as there's no seq. block number
)
