Abstract
This EIP introduces a new EIP-2718 transaction type with EIP-1559 gas fields, typed capabilities (CALL and CREATE) that define the transaction's operations, a separate signatures list for authentication, a fee_auth field that executes account code to sponsor gas, and four new opcodes — RETURNETH, SIG, SIGHASH, and TX_GAS_LIMIT — for fee delegation and in-EVM transaction introspection.
