anchor

README

Psyoptions & Zetamarkets uses Anchor (+ Serum), a framework for Solana's Sealevel runtime providing several convenient developer tools for writing smart contracts. https://github.com/project-serum/anchor

We want to automcatically query all the available options from Psyoptions/Zeta. To do so, we will use anchor-go which generates Go clients for Solana programs (smart contracts) written using the anchor framework.

go get github.com/gagliardetto/anchor-go
go run github.com/gagliardetto/anchor-go --src=idl.json

For PsyOptions (Zeta is coded way too diffrently), we actually only need the structure:

type OptionMarket struct {
	OptionMint                  ag_solanago.PublicKey
	WriterTokenMint             ag_solanago.PublicKey
	UnderlyingAssetMint         ag_solanago.PublicKey
	QuoteAssetMint              ag_solanago.PublicKey
	UnderlyingAmountPerContract uint64
	QuoteAmountPerContract      uint64
	ExpirationUnixTimestamp     int64
	UnderlyingAssetPool         ag_solanago.PublicKey
	QuoteAssetPool              ag_solanago.PublicKey
	MintFeeAccount              ag_solanago.PublicKey
	ExerciseFeeAccount          ag_solanago.PublicKey
	Expired                     bool
	BumpSeed                    uint8
}

from the file accounts.go

idl file is copied from :

curl https://raw.githubusercontent.com/mithraiclabs/psyoptions-ts/master/packages/psy-american/src/idl.json -o idl.json

But it can also be generated using the anchor cli doing something like:

anchor idl parse -f lib.rs -o idl.json

Note: There are 2 Solana go libraries and they are pretty similar:

github.com/gagliardetto/solana-go

github.com/streamingfast/solana-go

We were using the second one but since anchor-go is from the same authors as the first one, we also have to use that lib. In a perfect world, we should only use one of them but that would require some refactoring that I am not doing now.

Types

type Option

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

func Query

func Query() ([]Option, error)

func (*Option) Asset

func (o *Option) Asset() string

func (*Option) ContractSize

func (o *Option) ContractSize() float64

func (*Option) Expiration

func (o *Option) Expiration() string

Expiration will be used in .Name() when fixed.

func (*Option) IsCall

func (o *Option) IsCall() bool

func (*Option) IsExpired

func (o *Option) IsExpired() bool

the Options have a field "Expired"(bool) but it is not set to false even for expired hence the function. INFO: copy from opyn.go. should make a proper function we keep an option even 2 days after expiry mainly because not all protocol stop at expiry or right before TODO re-check later.

func (*Option) Name

func (o *Option) Name() string

func (*Option) OptionMarketAddress

func (o *Option) OptionMarketAddress() solana.PublicKey

func (*Option) OptionType

func (o *Option) OptionType() string

func (*Option) Quote

func (o *Option) Quote() string

func (*Option) QuotePerContract
