Creating and Managing Accounts
Kaptos provides a few ways to generate account credentials, both legacy and
SingleKeyAccounts. You can either generate a new account or derive
an account from a private key.
Legacy Account
Kaptos offers a straightforward method to generate a legacy account using the
Account class. By invoking the static method generate(), you can create a new
legacy account either by passing no arguments or by explicitly setting
the scheme to SigningSchemeInput.Ed2551 and the legacy property to true as
shown below.
Generate a New Account
To create a new legacy account, you can generate a new account credential using the
Account.generate() method. This method will create a new account with a new
key pair.
val account = Account.generate()You can also use the Ed25519Account class that provides a nullary method,
generate(), to create a new account:
val account = Ed25519Account.generate()Derive an Account from a Private Key
If you have a private key, you can use it to create an Account object to manage
those credentials.
val privateKey = Ed25519PrivateKey("myEd25519privatekeystring")
val account = Account.fromPrivateKey(privateKey)Single Key Account
The SDK offers two ways to generate a single key account: using either the
SingleKeyAccount or the Account class. In both cases, you can create a
new account by calling the static generate() method. You’ll need to specify
the scheme, and for the Account class, you can optionally set the legacy
property to false.
val secp256k1SKAccount = SingleKeyAccount.generate(SigningSchemeInput.Secp256k1)
val ed25519SKAccount = SingleKeyAccount.generate(SigningSchemeInput.Ed25519)Using the Account class, you can create a new single key account by setting
the scheme to SigningSchemeInput.Secp256k1 and optionally setting the
legacy property to false. Alternatively, you can set the scheme to
SigningSchemeInput.Ed25519 and ensure the legacy property is also
set to false.
val secp256k1SKAccount = Account.generate(scheme = SigningSchemeInput.Secp256k1)
val ed25519SKAccount = Account.generate(scheme = SigningSchemeInput.Ed25519, legacy = false)On-chain Account Creation
It is also worth noting that Account generation does not create the account on-chain. You must fund the account on-chain to use it for transactions. On test networks, you can fund an account programmatically by asking a “faucet” for test tokens. You can do this as shown below:
val fundedAccount = aptos.fundAccount(aliceAccount.accountAddress, FUNDING_AMOUNT)
