The documentation, Create Direct Custody Wallets, says that with an omnibus wallet structure there is no gas fee for internal transactions.
What counts as internal transactions in this regard?
Hi @fredrikl–when the article mentions no fees for settling transfers within an omnibus wallet structure, it refers to settling operations on an internal and off-chain ledger to track customer funds.
When an omnibus wallet structure is used, any funds kept on the platform are generally swept into a single vault. In this architecture, customer funds are stored in a single vault, and any movements of funds between customers can happen in a ledger system maintained by you. This ledger can reflect transfers, sales, or purchases as needed, and you can credit/debit customers on this ledger despite no operations taking place on-chain. This means no on-chain fees are charged given operations are settled on your internal ledger.
