Gas & Fees

EIP-1153 introduced transient storage: data that exists only for a transaction and is automatically cleared afterward. TSTORE/TLOAD can be cheaper than persistent storage for temporary values such as reentrancy locks, but any user-level gas savings depend on the surrounding implementation and current transaction estimate.

ERC-1363 defines transferAndCall and approveAndCall receiver interfaces for tokens and compatible contracts. When both sides implement the relevant callback, one transaction can transfer tokens and invoke a contract action; callback success does not by itself guarantee the business service outcome.

EIP-1559 defines Ethereum's type-2 fee market: a base fee, optional priority fee, max fee cap, and base-fee burn on Ethereum. Monad supports EIP-1559-compatible type-2 transactions but uses chain-specific accounting: gas is charged from the gas limit and its base-fee controller differs from Ethereum's. Label the network and verify fee accounting instead of reusing Ethereum burn, recipient, adjustment, or capacity claims.

ERC-2771 defines a contract-level protocol for recipients that accept meta-transactions through trusted forwarders. A gas relay may submit a signed request and pay gas, but gasless interaction requires a recipient integration, trusted-forwarder verification, an available relay, and any sponsor policy the product chooses.

ERC-4337 supports smart-account flows that can offer sponsored fees, batched actions, or account recovery when the chosen implementation supports them. Show which options are available, who pays, and what happens if an operation fails. These features are not guaranteed by ERC-4337 alone.

EIP-4844 introduced Type 3 blob transactions so rollups can post data using a separate blob-fee market. This can lower data costs, but the end-user fee depends on the rollup, execution costs, demand and its pricing policy. Show a current network-specific estimate rather than a fixed dollar price or savings guarantee.

EIP-7702 lets an existing externally owned account delegate execution to contract code while keeping its address. Delegation persists until replaced or cleared and gives the code unrestricted account access. The wallet must audit the code; applications must not request authorization signatures. Batching, sponsorship, and scoped app permissions depend on compatible wallet implementations.

EIP-7825 caps an Ethereum transaction's gas limit at 16,777,216 gas (2^24) on networks that activate it. Ethereum included the cap in Fusaka, which activated on mainnet on December 3, 2025. Large batch and deployment flows need a network-aware preflight and a recovery path that splits or redesigns oversized operations; eth_call is not subject to this transaction cap.

MIP-3 changes how Monad prices memory-heavy transactions. Show a Monad-aware fee estimate and surface simulation failures before signing. Memory is shared across calls under an 8 MiB cap, so linear pricing does not guarantee a lower fee or successful execution.

MIP-4 adds a precompile at 0x1001 with dippedIntoReserve(), which returns an ABI-encoded bool describing whether the current execution state has dipped into reserve across all accounts touched by the transaction. It is an in-execution contract check, not a reserve-amount query or a wallet preflight for an arbitrary unsigned transaction.

ERC-5453 builds on ERC-5750 to let an opted-in contract method accept endorsement data for a relayed call. It is not a universal permit for every function: the target contract must implement the relevant method and final bytes extraData shape, and execution/atomicity remain contract and relayer behavior.

ERC-7677 defines the Paymaster Web Service Capability for EIP-5792. It describes wallet capability discovery and service RPCs such as pm_getPaymasterStubData and pm_getPaymasterData; it is not a universal paymaster contract interface and does not guarantee sponsorship.

EIP-8141 is a Draft frame-transaction proposal for native account abstraction. Its current design can let compatible accounts use default code for batching or alternative fee payment, but it does not configure universal recovery or key rotation for every existing account.

EIP-7702 is opt-in code delegation for EOAs on Monad. While delegated, a transaction that reduces the EOA's balance below the applicable reserve threshold reverts, subject to the documented max-gas-fee allowance. The current reserve parameter is 10 MON, not a required deposit; sponsored low-balance calls can work when the balance is unchanged or increased. Delegated accounts cannot use the emptying exception.

Monad's Reserve Balance mechanism coordinates consensus-time inflight gas budgets with execution-time ending-balance checks. The current system parameter is user_reserve_balance = 10 MON, but outcomes depend on lagged and starting balances, gas and value spend, delegation, recent activity, and emptying eligibility. It is not a universal balance-minus-10-MON formula or an upfront deposit.

Monad uses a chain-specific gas schedule and charges the signed gas limit at the applicable price, so fee previews need an estimate for the actual transaction and active revision. Page and account access, operation, and state growth determine gas; a blanket Ethereum multiplier cannot describe that behavior.
