Auth Precompile - Sei Docs

Address: 0x000000000000000000000000000000000000100D The Auth precompile reads data from the Cosmos auth module: account details, module parameters, and the next account number. All methods are view functions. The precompile is available since v6.7.0.

Methods

Method	Returns
`account(addr)`	The Sei address, account number, and sequence of the account linked to `addr`.
`accounts(pageKey)`	All accounts, one page at a time.
`params()`	The `auth` module parameters.
`nextAccountNumber()`	The account number that the next new account gets. The call does not change the counter.

Notes

account() reverts if addr has no associated Sei address, or if no account exists for it.
For accounts(), pass empty bytes for the first page, then pass the returned nextKey. An empty nextKey means there are no more pages.
