  • Impact: The address whose account is queried.

Function: get_sequence_number

Gets the sequence number of an account.

Inputs

Full prototype: #[view] public fun get_sequence_number(addr: address): u64

• addr: address

  • Validation: Checks that the account exists.

  • Impact: The address whose account is queried.

Function: is_base_account

Checks if the address is a base account type. That is, not a table, object, or other special type of account.

Inputs

Full prototype: #[view] public fun is_base_account(addr: address): bool

• addr: address

  • Validation: Checks that the account exists.

  • Impact: The address whose account is queried.

Function: is_object_account

Checks if the address is an object account type.

Inputs

Full prototype: #[view] public fun is_object_account(addr: address): bool

• addr: address

  • Validation: Checks that the account exists.

  • Impact: The address whose account is queried.

Function: is_table_account

Checks if the address is an table account type.

Inputs

Full prototype: #[view] public fun is_table_account(addr: address): bool

• addr: address

  • Validation: Checks that the account exists.

  • Impact: The address whose account is queried.

Function: is_module_account

Checks if the address is a module account type.

Inputs

Full prototype: #[view] public fun is_module_account(addr: address): bool

• addr: address

  • Validation: Checks that the account exists.

  • Impact: The address whose account is queried.

Function: get_account_info

Calls the Cosmos get_account_info interface.

Inputs

Full prototype: native public fun get_account_info(addr: address): (bool /* found */, u64 /* account_number */, u64 /* sequence_number */, u8 /* account_type */)

• addr: address

  • Validation: None necessary — error returned if not found.

  • Impact: The address whose data is queried.

Function: create_address

Parses an address from a u8 vector into an address type.

Inputs

Full prototype: native public(friend) fun create_address(bytes: vector<u8>): address

• bytes: vector<u8>

  • Validation: The vector is of the correct length.

  • Impact: The bytes that are parsed into the address.

Function: create_signer

This internal function converts an address into a signer for non-base accounts.

Inputs

Full prototype: native public(friend) fun create_signer(addr: address): signer

• addr: address

  • Validation: None.
