Basic Examples  (1)

Encode a public key as a Pay-to-Public-Key-Hash Bitcoin address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["Bitcoin" ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address"]

Scope  (5)

Address  (1)

Encode a public key as an Ethereum address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["Ethereum" ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> "Ethereum"]

Hexadecimal string  (1)

Encode a hexadecimal private key string to an Ethereum address:

Wolfram Language code: pKey = "4da3a53bd77c43eecbb7e38c0a25f9d7e14ab204e276cfde742bc4bfd0624ce4";
Wolfram Language code: BlockchainKeyEncode[pKey, "Address", BlockchainBase -> "Ethereum"]

Private key  (1)

Encode a private key as a Bitcoin address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["Bitcoin" ]
Wolfram Language code: BlockchainKeyEncode[keys["PrivateKey"], "Address", BlockchainBase -> "Bitcoin"]

Public key  (1)

Encode a public key as a Bitcoin address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["Bitcoin" ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> "Bitcoin"]

WIF  (1)

Encode a private key as a WIF-compressed format to be used in a transaction on the Bitcoin blockchain:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["Bitcoin" ]
Wolfram Language code: BlockchainKeyEncode[keys["PrivateKey"], "WIF", BlockchainBase -> "Bitcoin"]

Options  (14)

BlockchainBase  (14)

ARK  (2)

Encode a public key as an ARK address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["ARK" ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> "ARK"]

Encode a public key as an ARK devnet address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["ARK" ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> {"ARK", "Devnet"}]

Bitcoin  (2)

Encode a public key as a Bitcoin address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["Bitcoin" ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> "Bitcoin"]

Encode a public key as a Bitcoin testnet address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["Bitcoin" ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> {"Bitcoin", "Testnet"}]

Bitcoin Cash  (1)

Encode a public key as a Bitcoin Cash address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["Bitcoin" ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> "BitcoinCash"]

bloxberg  (1)

Encode a public key as a bloxberg address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["Ethereum" ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> "bloxberg"]

Cardano  (3)

Encode an ed25519 public key as a Cardano enterprise address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair[Method -> <|"Type" -> "EdwardsCurve", "CurveName" -> "ed25519"|>]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> "Cardano"]

This is equivalent to explicitly specifying the key in the association:

Wolfram Language code: BlockchainKeyEncode[<|"PaymentKey" -> keys["PublicKey"]|>, "Address", BlockchainBase -> "Cardano"]

Encode an ed25519 public key as a Cardano stake address:

Wolfram Language code: stakeKeys = GenerateAsymmetricKeyPair[Method -> <|"Type" -> "EdwardsCurve", "CurveName" -> "ed25519"|>]
Wolfram Language code: BlockchainKeyEncode[<|"StakeKey" -> stakeKeys["PublicKey"]|>, "Address", BlockchainBase -> "Cardano"]

Encode two ed25519 public keys (payment and stake keys) as a Cardano payment address:

Wolfram Language code: paymentKeys = GenerateAsymmetricKeyPair[Method -> <|"Type" -> "EdwardsCurve", "CurveName" -> "ed25519"|>]
Wolfram Language code: stakeKeys = GenerateAsymmetricKeyPair[Method -> <|"Type" -> "EdwardsCurve", "CurveName" -> "ed25519"|>]
Wolfram Language code: BlockchainKeyEncode[<|"PaymentKey" -> paymentKeys["PublicKey"], "StakeKey" -> stakeKeys["PublicKey"]|>, "Address", BlockchainBase -> "Cardano"]

Ethereum  (1)

Encode a public key as an Ethereum address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["Ethereum" ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> "Ethereum"]

Litecoin  (1)

Encode a public key as a Litecoin address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["Bitcoin" ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> "Litecoin"]

Tezos  (3)

Encode an ed25519 public key as a Tezos address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair[Method -> <|"Type" -> "EdwardsCurve", "CurveName" -> "ed25519"|> ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> "Tezos"]

Encode a secp256k1 public key as a Tezos address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair[Method -> <|"Type" -> "EllipticCurve", "CurveName" -> "secp256k1"|>]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> "Tezos"]

Encode a prime256v1 public key as a Tezos address:

Wolfram Language code: keys = GenerateAsymmetricKeyPair[Method -> <|"Type" -> "EllipticCurve", "CurveName" -> "prime256v1"|>]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "Address", BlockchainBase -> "Tezos"]

Possible Issues  (2)

Encoding a public key as WIF format will return an error:

Wolfram Language code: keys = GenerateAsymmetricKeyPair["Bitcoin" ]
Wolfram Language code: BlockchainKeyEncode[keys["PublicKey"], "WIF", BlockchainBase -> "Bitcoin"]

When encoding a hexadecimal string as a Tezos address, BlockchainKeyEncode will assume it is an ed25519 public key:

Wolfram Language code: BlockchainKeyEncode["201f3912af1df384f64708a03a6d4b3255777c9f7404150a9e593f8ae202e274", "Address", BlockchainBase -> "Tezos"]
