# EVM Compatibility

> EVM feature support on Sei — what works, what differs from Ethereum, and what is not available

# EVM Compatibility

This page documents Sei's EVM feature support. Each row shows whether a capability works as on standard Ethereum, behaves differently in a documented way, or is not available on Sei.

Standard EVM tooling — viem, wagmi, ethers, Foundry, Hardhat — works on Sei for all rows marked **Supported**. Where Sei differs from Ethereum, the difference is noted so you can account for it in your application.

## Status Legend

| Status                  | Meaning                                                                   |
| ----------------------- | ------------------------------------------------------------------------- |
| Supported               | Works on Sei EVM with standard Ethereum behavior.                         |
| Supported — differences | Available on Sei, but intentionally differs from Ethereum. See the notes. |
| Sei extension           | A Sei-specific capability with no standard Ethereum equivalent.           |
| Not supported           | Not available on Sei EVM.                                                 |

## Transactions

| Feature                                    | Sei status              | Notes                                                                                                                       |
| ------------------------------------------ | ----------------------- | --------------------------------------------------------------------------------------------------------------------------- |
| Legacy transactions (type 0)               | Supported — differences | Minimum gas price is set by Sei governance parameters, not a fixed floor. [See Gas and Fees.](/evm/evm-parity/gas-and-fees) |
| EIP-2930 access list transactions (type 1) | Supported               |                                                                                                                             |
| EIP-1559 fee market transactions (type 2)  | Supported — differences | No base-fee burning. Fees go to validators rather than being burned. [See Gas and Fees.](/evm/evm-parity/gas-and-fees)      |
| EIP-4844 blob transactions (type 3)        | Not supported           | Sei runs Pectra without blob transactions. [See Transaction Types.](/evm/evm-parity/transaction-types)                      |
| EIP-7702 set-code transactions (type 4)    | Supported               |                                                                                                                             |

| `eth_getTransactionCount` (nonce) | Supported               |                                                                                                                                                                             |
| `eth_getCode`                     | Supported               |                                                                                                                                                                             |
| `eth_getStorageAt`                | Supported — differences | SSTORE cost is governance-adjustable; do not hard-code gas assumptions. [See Gas and Fees.](/evm/evm-parity/gas-and-fees)                                                   |
| `eth_getProof`                    | Supported — differences | Returns IAVL proof data rather than Ethereum Merkle Patricia Trie proofs. Proof verification logic must account for this. [See State Proofs.](/evm/evm-parity/state-proofs) |

## Blocks and Finality

| Feature                                       | Sei status              | Notes                                                                                                                                             |

| Finality tags (`latest`, `safe`, `finalized`) | Supported — differences | Sei has instant finality. All three tags refer to the same commitment level. [See Finality.](/evm/evm-parity/finality)                            |
| Pending block state                           | Supported — differences | Ethereum-style pending state visibility is not guaranteed. Do not rely on pending transaction ordering. [See Finality.](/evm/evm-parity/finality) |

| -------- | ---------- | -------------------------------------------------------------- |
| ERC-4337 | Supported  | Requires a compatible bundler. Sei EVM is ERC-4337 compatible. |

## Name Services

| Feature | Sei status    | Notes                                                                                                |
| ------- | ------------- | ---------------------------------------------------------------------------------------------------- |
| ENS     | Not supported | Sei does not run Ethereum mainnet ENS. Application-level name services can be deployed as contracts. |

## Sei Extensions

These capabilities are Sei-specific and have no standard Ethereum equivalent. They are exposed through `@sei-js` packages layered on top of standard EVM tooling.

| Feature                                                                                  | Notes                                                                                                                                                |
| ---------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
| Sei precompiles (staking, governance, distribution, oracle, P256, JSON, CosmWasm bridge) | EVM contracts at deterministic addresses. ABIs and contract addresses are exported from `@sei-js/precompiles` for use with any standard EVM library. |
| Pointer contracts (CW20 ↔ ERC-20, CW721 ↔ ERC-721)                                       | Bridge between CosmWasm and EVM token standards. Standard ERC interfaces work against pointer contracts.                                             |
| Native address association (EVM ↔ Cosmos address)                                        | Links an EVM address and a Cosmos address for the same account. Required before some Sei-native flows.                                               |
| TokenFactory native token creation                                                       | Create native Sei tokens that are usable across EVM and CosmWasm without a wrapper contract.                                                         |

## Unsupported RPC Methods

The following JSON-RPC methods are either not available on Sei or will return errors:

### Blob / EIP-4844

| Method              | Reason                                                                               |
| ------------------- | ------------------------------------------------------------------------------------ |
| `eth_blobBaseFee`   | Sei runs Pectra without blob transaction support. This method does not exist on Sei. |
| `engine_getBlobsV1` | Blob data availability endpoints are not supported.                                  |

### Pending State

| Method                                        | Behavior on Sei                                                                                                                               |
| --------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------- |
| `eth_getBlockByNumber("pending")`             | Returns `null` or the latest committed block. Sei does not maintain an Ethereum-style pending block.                                          |
| `eth_getTransactionCount(address, "pending")` | Returns the same value as `"latest"`. Pending nonce does not differ from confirmed nonce on Sei.                                              |
| `eth_newPendingTransactionFilter`             | The filter can be created but will not reliably emit pending transactions. Use `eth_newBlockFilter` or WebSocket block subscriptions instead. |
| `eth_subscribe("newPendingTransactions")`     | Supported at the RPC level but Sei does not guarantee Ethereum-style pending transaction visibility. Treat results as best-effort.            |

### Proof Verification

| Method         | Behavior on Sei                                                                                                                                                                                                           |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `eth_getProof` | Returns IAVL tree proofs, not Ethereum Merkle Patricia Trie proofs. The method itself works, but the proof format is incompatible with standard Ethereum MPT verifiers. [See State Proofs.](/evm/evm-parity/state-proofs) |

### Deprecated / Removed Opcodes

| Method         | Reason                                                                                                                                          |
| -------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- |
| `eth_accounts` | Returns an empty array on Sei RPC nodes. Use a wallet library (`eth_requestAccounts`) to get accounts from the connected user's wallet instead. |
