Functions

func CreateProgramAddress 

func CreateProgramAddress(program ed25519.PublicKey, seeds ...[]byte) (ed25519.PublicKey, error)

CreateProgramAddress mirrors the implementation of the Solana SDK's CreateProgramAddress.

ProgramAddresses are public keys that _do not_ lie on the ed25519 curve to ensure that there is no associated private key. In the event that the program and seed parameters result in a valid public key, ErrInvalidPublicKey is returned.

Reference: https://github.com/solana-labs/solana/blob/5548e599fe4920b71766e0ad1d121755ce9c63d5/sdk/program/src/pubkey.rs#L158

func FindProgramAddress 

func FindProgramAddress(program ed25519.PublicKey, seeds ...[]byte) (ed25519.PublicKey, error)

FindProgramAddress mirrors the implementation of the Solana SDK's FindProgramAddress. It only returns the address.

Reference: https://github.com/solana-labs/solana/blob/5548e599fe4920b71766e0ad1d121755ce9c63d5/sdk/program/src/pubkey.rs#L234

func FindProgramAddressAndBump 

func FindProgramAddressAndBump(program ed25519.PublicKey, seeds ...[]byte) (ed25519.PublicKey, uint8, error)

FindProgramAddressAndBump mirrors the implementation of the Solana SDK's FindProgramAddress. It returns the address and bump seed.

Reference: https://github.com/solana-labs/solana/blob/5548e599fe4920b71766e0ad1d121755ce9c63d5/sdk/program/src/pubkey.rs#L234
