    @mount("ft4.register_account") operation register_account()
    source

    An operation which can be called to create an account. This operation is part of the account registration framework and it must be preceded by a strategy operation which contains information about how the account is supposed to be registered.

    Throws if the operation that came just before this one cannot be handled. Common cases are:

    • the operation is not registered as a strategy operation through extensions of strategy
    • the operation has been misconfigured, and its name does not match the operation mount name

    Throws if the signature verification is unsuccessful. Common cases are:

    • evm_signatures is misconfigured:
      • any of the signers and signatures don't match in the exact order they're found
      • any of the signatures is null
      • there's more signatures than signers
    • a signature from one of the auth descriptor participants is missing:
      • an EVM signer is specified but the signature is not found in evm_signatures
      • an FT signer is specified but the signature is not in the transaction
      • a signer passed is neither an EVM nor an FT signer (its length does not match either of core.auth.EVM_ADDRESS_SIZE and core.auth.FT_PUBKEY_SIZE)

    Throws if either auth descriptor is invalid. Common cases include:

    • the main auth descriptor has expiration rules instead of core.accounts.GTV_NULL
    • the disposable auth descriptor's expiration rules:
      • is a complex rule with too many rule components
      • has already expired
      • is not the valid GTV representation of a rule
    • errors with the args field:
      • some required flags are missing
      • in multi-sig auth descriptors, the required_signatures field:
        • is 0 or less
        • is greater than the number of signers

    Throws if core.accounts.AUTH_DESCRIPTORS_PER_ACCOUNT_UPPER_BOUND is set to 1 and disposable passed to the strategy operation is not null.

    Throws if some conditions added in development through extensions (before_register_account or after_register_account) aren't met
