List of public keys

items[].​idstring(uuid)(UUID)required

Unique identifier in UUID format

Example: "550e8400-e29b-41d4-a716-446655440000"
items[].​valuestring(PublicKeyValue)^(xpub|ypub|zpub|tpub|vpub|upub)[1-9A-HJ-NP-Z...required

Extended public key encoded in Base58Check format, compliant with BIP32 and SLIP-0132 specifications.

An extended public key allows deriving a hierarchy of child public keys and addresses without exposing the corresponding private keys.

Supported prefixes and address derivation types:

Mainnet

  • xpub — Legacy P2PKH (BIP44), addresses typically starting with 1
  • ypub — SegWit P2SH-P2WPKH (BIP49), addresses typically starting with 3
  • zpub — Native SegWit P2WPKH (BIP84), addresses typically starting with bc1

Testnet

  • tpub — Legacy P2PKH (BIP44)
  • upub — SegWit P2SH-P2WPKH (BIP49)
  • vpub — Native SegWit P2WPKH (BIP84)

The prefix defines both the address derivation scheme and the target network (mainnet or testnet). The actual address format depends on the selected derivation path and network parameters.

Example: "xpub6EFxzN6ZgMCZ1PxeRigmAhm2UBGzXtZNgznCEaWuEt9efBpJwAXFA4ZckBdR1pdMQ1pBgsey7ebjToZ5gYXveftB3zwoQ8NvEkimvyaz34i"

User-friendly label for the public key

Example: "Main Wallet"
items[].​derivation_pathstring(DerivationPath)^m/(44|49|84)'/\d+'\/\d+'\/\d+$required

HD wallet derivation path that identifies the address type, blockchain network, and account. Follows BIP44/49/84 standards with format: m / purpose' / coin_type' / account' / change

The purpose field indicates the address type:

  • 44' for P2PKH addresses (Legacy)
  • 49' for P2SH-P2WPKH addresses (SegWit)
  • 84' for P2WPKH addresses (Native SegWit)

Common examples:

  • m/44'/0'/0'/0 — Bitcoin Legacy external addresses
  • m/44'/0'/0'/1 — Bitcoin Legacy change addresses
  • m/49'/0'/0'/0 — Bitcoin SegWit external addresses
  • m/84'/0'/0'/0 — Bitcoin Native SegWit external addresses
  • m/44'/60'/0'/0 — Ethereum or Binance Smart Chain (BEP20) addresses
  • m/44'/137'/0'/0 — Polygon addresses
  • m/44'/714'/0'/0 — Binance Chain (BEP2) addresses

The coin_type value follows SLIP-0044 registered coin types (e.g., 0 for Bitcoin, 60 for Ethereum, 137 for Polygon, 714 for Binance Chain).

Example: "m/84'/0'/0'/0"
items[].​created_atstring(date-time)(CreatedAt)required

Timestamp when the resource was created

Example: "2024-01-15T10:30:00Z"

Add new public key

Request

A blockchain address in its native format. This is a generic schema for any blockchain address, including addresses, smart contract addresses, and token contract addresses.

The actual format depends on the blockchain network:

  • EVM chains (Ethereum, BSC, Polygon, etc.): 0x followed by 40 hexadecimal characters

    • Example: 0x8521E8b15eCEF4D4269Fded3E6694225E096959E

  • Bitcoin: Various formats depending on address type

    • P2PKH (Legacy): Starts with 1, Example: 1GxHzNEymq1MLhxpdWAMJLN1UusYJ2Sy45
    • P2SH (Wrapped SegWit): Starts with 3, Example: 3Do92Dmff87UuY9Yiu2iFG2Kj9bpRaeJSF
    • P2WPKH (Native SegWit): Starts with bc1, Example: bc1q8faxe8g4u2v67qfwf9d8xhyl5tkkkphvet6r08

  • Solana: Base58 encoded, 32-44 characters

    • Example: 5EYCAe5ijiHbZBU14TyKHADUrkaAfc4ZyTXKRVKp49F8

  • Tron: Base58 encoded addresses starting with T

    • Example: TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t

  • Cosmos ecosystem: Bech32 format with chain-specific prefix

    • Example: cosmos1vx8knpllrj7n963p9ttd80w47kpacrhuts497x

This schema is intentionally generic to support addresses from any blockchain. The specific validation rules depend on the blockchain network and address type.

Example: "0x8521E8b15eCEF4D4269Fded3E6694225E096959E"

Generate addresses from public key

Request

Generates multiple HD addresses from the public key using either specific indexes or a range. The address format is automatically determined based on the public key's derivation path.

You can specify either:

  • A list of specific indexes to generate addresses for
  • A range (from/to) to generate consecutive addresses

If neither is specified, generates a single address at the next available index.

public_key_idstring(uuid)(UUID)required

valuestring(AddressValue)[ 1 .. 128 ] characters^[a-zA-Z0-9]+$required

A blockchain address in its native format. This is a generic schema for any blockchain address, including addresses, smart contract addresses, and token contract addresses.

The actual format depends on the blockchain network:

  • EVM chains (Ethereum, BSC, Polygon, etc.): 0x followed by 40 hexadecimal characters

    • Example: 0x8521E8b15eCEF4D4269Fded3E6694225E096959E

  • Bitcoin: Various formats depending on address type

    • P2PKH (Legacy): Starts with 1, Example: 1GxHzNEymq1MLhxpdWAMJLN1UusYJ2Sy45
    • P2SH (Wrapped SegWit): Starts with 3, Example: 3Do92Dmff87UuY9Yiu2iFG2Kj9bpRaeJSF
    • P2WPKH (Native SegWit): Starts with bc1, Example: bc1q8faxe8g4u2v67qfwf9d8xhyl5tkkkphvet6r08

  • Solana: Base58 encoded, 32-44 characters

    • Example: 5EYCAe5ijiHbZBU14TyKHADUrkaAfc4ZyTXKRVKp49F8

  • Tron: Base58 encoded addresses starting with T

    • Example: TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t

  • Cosmos ecosystem: Bech32 format with chain-specific prefix

    • Example: cosmos1vx8knpllrj7n963p9ttd80w47kpacrhuts497x

This schema is intentionally generic to support addresses from any blockchain. The specific validation rules depend on the blockchain network and address type.
