Class PublicKey

constructor

• new PublicKey(value: PublicKeyInitData): PublicKey

  Create a new PublicKey object

  Parameters

  • value: PublicKeyInitData

    ed25519 public key as buffer or base-58 encoded string

  Returns PublicKey

Staticdefault

[toStringTag]

• get "[toStringTag]"(): string

  Returns string

equals

• equals(publicKey: PublicKey): boolean

  Checks if two publicKeys are equal

  Parameters

  • publicKey: PublicKey

  Returns boolean

toBase58

• toBase58(): string

  Return the base-58 representation of the public key

  Returns string

toBuffer

• toBuffer(): Buffer

  Return the Buffer representation of the public key in big endian

  Returns Buffer

toBytes

• toBytes(): Uint8Array

  Return the byte array representation of the public key in big endian

  Returns Uint8Array

toJSON

• toJSON(): string

  Returns string

toString

• toString(): string

  Return the base-58 representation of the public key

  Returns string

StaticcreateProgramAddress

• createProgramAddress(
      seeds: (Uint8Array<ArrayBufferLike> | Buffer<ArrayBufferLike>)[],
      programId: PublicKey,
  ): Promise<PublicKey>

  Async version of createProgramAddressSync For backwards compatibility

  Parameters

  • seeds: (Uint8Array<ArrayBufferLike> | Buffer<ArrayBufferLike>)[]
  • programId: PublicKey

  Returns Promise<PublicKey>

  Deprecated

  Use createProgramAddressSync instead

StaticcreateProgramAddressSync

• createProgramAddressSync(
      seeds: (Uint8Array<ArrayBufferLike> | Buffer<ArrayBufferLike>)[],
      programId: PublicKey,
  ): PublicKey

  Derive a program address from seeds and a program ID.

  Parameters

  • seeds: (Uint8Array<ArrayBufferLike> | Buffer<ArrayBufferLike>)[]
  • programId: PublicKey

  Returns PublicKey

StaticcreateWithSeed

• createWithSeed(
      fromPublicKey: PublicKey,
      seed: string,
      programId: PublicKey,
  ): Promise<PublicKey>

  Derive a public key from another key, a seed, and a program ID. The program ID will also serve as the owner of the public key, giving it permission to write data to the account.

  Parameters

  • fromPublicKey: PublicKey
  • seed: string
  • programId: PublicKey

  Returns Promise<PublicKey>

StaticfindProgramAddress

• findProgramAddress(
      seeds: (Uint8Array<ArrayBufferLike> | Buffer<ArrayBufferLike>)[],
      programId: PublicKey,
  ): Promise<[PublicKey, number]>

  Async version of findProgramAddressSync For backwards compatibility

  Parameters

  • seeds: (Uint8Array<ArrayBufferLike> | Buffer<ArrayBufferLike>)[]
  • programId: PublicKey

  Returns Promise<[PublicKey, number]>

  Deprecated

  Use findProgramAddressSync instead

StaticfindProgramAddressSync

• findProgramAddressSync(
      seeds: (Uint8Array<ArrayBufferLike> | Buffer<ArrayBufferLike>)[],
      programId: PublicKey,
  ): [PublicKey, number]

  Find a valid program address

  Valid program addresses must fall off the ed25519 curve. This function iterates a nonce until it finds one that when combined with the seeds results in a valid program address.

  Parameters

  • seeds: (Uint8Array<ArrayBufferLike> | Buffer<ArrayBufferLike>)[]
  • programId: PublicKey

  Returns [PublicKey, number]

StaticisOnCurve

• isOnCurve(pubkeyData: PublicKeyInitData): boolean

  Check that a pubkey is on the ed25519 curve.

  Parameters

  • pubkeyData: PublicKeyInitData

  Returns boolean

Staticunique

• unique(): PublicKey

  Returns a unique PublicKey for tests and benchmarks using a counter

  Returns PublicKey
