Wallet API

Internal Transactions (`with-internal`)

Linea supports internal transactions (traces). The Transactions API endpoints marked with-traces above accept the with-internal=true query parameter, which includes internal transactions (the value transfers triggered by contract execution that are not recorded as standalone onchain transactions) in the response.

Internal transactions are included in the response by passing with-internal and cost 0.05 credits/item.
