EnsureATA returns (and possibly creates) the owner's associated token account (ATA) for the given mint.

func EnsureATAs 

func EnsureATAs(ctx context.Context, cl *rpc.Client, mint solana.PublicKey, owners ...solana.PrivateKey) (map[solana.PublicKey]solana.PublicKey, error)

EnsureATAs finds or creates the owners' associated token account (ATA) for the given mint.

func FillHash 

func FillHash(
	orderID [32]byte,
	srcChainID uint64,
	destChainID uint64,
	fillDeadline uint32,
	callTarget common.Address,
	callSelector [4]byte,

	expenseSpender common.Address,
	expenseToken common.Address,
	expenseAmount *big.Int,
) (common.Hash, error)

FillHash returns the fill hash for the given parameters.

func FilterDataLogs 

func FilterDataLogs(logs []string, program solana.PublicKey) ([]string, bool, error)

FilterDataLogs filters the logs for a specific program, returning only the data logs and true if logs were not truncated.

func GetAccountDataInto 

func GetAccountDataInto(ctx context.Context, cl *rpc.Client, address solana.PublicKey, val any) (*rpc.GetAccountInfoResult, error)

GetAccountDataInto retrieves account data and decodes it into the provided value. It uses commitment level of "confirmed".

func GetBlock 

func GetBlock(ctx context.Context, cl *rpc.Client, slot uint64, details rpc.TransactionDetailsType) (*rpc.GetBlockResult, bool, error)

GetBlock is a convenience function returning the block for the given slot, or false if no block found for the slot, or and error.

func MapEVMKey 

func MapEVMKey(key *ecdsa.PrivateKey) solana.PrivateKey

MapEVMKey returns a deterministic mapping of an EVM secp256k1 private key to a Solana ed25519 private key.

func NativeBalanceAt 

func NativeBalanceAt(ctx context.Context, cl *rpc.Client, addr solana.PublicKey) (*big.Int, error)

func RandomU96 

func RandomU96() bin.Uint128

RandomU96 generates a random 96-bit unsigned integer of type bin.Uint128.

func Redeploy 

func Redeploy(ctx context.Context, rpcAddr string, program Program, upgrader solana.PrivateKey) (*rpc.GetTransactionResult, error)

Redeploy redeployes/upgrades the program to the rpc network using the provided keys. It returns the confirmed transaction result or an error.

func SavePrivateKey 

func SavePrivateKey(key solana.PrivateKey, path string) error

SavePrivateKey saves a Solana private key to a file in JSON format.

func Send 

func Send(ctx context.Context, cl *rpc.Client, opts ...func(*sendOpts)) (solana.Signature, error)

func SendSimple 

func SendSimple(ctx context.Context, cl *rpc.Client, privkey solana.PrivateKey, instrs ...solana.Instruction) (solana.Signature, error)

func Start 

func Start(ctx context.Context, composeDir string) (*rpc.Client, string, solana.PrivateKey, func(), error)

Start starts a genesis solana node and returns a client, a funded private key and a stop function or an error. The dir parameter is the location of the docker compose.

func Stream 

func Stream(ctx context.Context, cl *rpc.Client, req StreamReq, callback StreamCallback) error

func TokenBalanceAt 

func TokenBalanceAt(ctx context.Context, cl *rpc.Client, mint, wallet solana.PublicKey) (*big.Int, error)

func U128 

func U128(i *big.Int) (bin.Uint128, error)

U128 returns the big int as a solana binary uint128.

func WithInstructions 

func WithInstructions(instrs ...solana.Instruction) func(*sendOpts)

func WithPrivateKeys 

func WithPrivateKeys(privkeys ...solana.PrivateKey) func(*sendOpts)

func WrapRPCError 

func WrapRPCError(err error, endpoint string, attrs ...any) error

Types

type CreateMintResp 

type CreateMintResp struct {
	MintAccount solana.PublicKey
	Authority   solana.PrivateKey
	ATAs        map[solana.PublicKey]solana.PublicKey // Map of funded associated token accounts
}

func CreateMint 

func CreateMint(
	ctx context.Context,
	cl *rpc.Client,
	authority solana.PrivateKey,
	mint solana.PrivateKey,
	decimals uint8,
	toFund ...solana.PublicKey,
) (CreateMintResp, error)

func (CreateMintResp) AuthATA 

func (r CreateMintResp) AuthATA() solana.PublicKey

type Program 

type Program struct {
	Name         string
	SharedObject []byte // Compiled BPF shared object
	KeyPairJSON  []byte
}

Program represents a Solana executable program (smart contract).

func Rebuild 

func Rebuild(ctx context.Context, program Program, key solana.PrivateKey, anchorDir string) (Program, error)
