EVM compatibility

This page documents EVM feature support on Sei. Each row shows whether a feature works as it does on standard Ethereum, behaves differently in a documented way, or is not available on Sei. Standard EVM tools (viem, wagmi, ethers, Foundry, and Hardhat) work on Sei for all rows marked Supported. Where Sei differs from Ethereum, the notes describe the difference so that you can account for it in your application.

Status legend

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

Transactions

Feature	Sei status	Notes
Legacy transactions (type 0)	Supported with differences	The minimum gas price comes from Sei governance parameters, not a fixed floor. See Gas and Fees.
EIP-2930 access list transactions (type 1)	Supported
EIP-1559 fee market transactions (type 2)	Supported with differences	Sei does not burn the base fee. Fees go to validators instead. See Gas and Fees.
EIP-4844 blob transactions (type 3)	Not supported	Sei runs Pectra without blob transactions. See Transaction Types.
EIP-7702 set-code transactions (type 4)	Supported

Account and state

Feature	Sei status	Notes
`eth_getBalance`	Supported
`eth_getTransactionCount` (nonce)	Supported
`eth_getCode`	Supported
`eth_getStorageAt`	Supported with differences	Governance can adjust the SSTORE cost. Do not hard-code gas assumptions. See Gas and Fees.
`eth_getProof`	Supported with differences	Returns IAVL proof data, not Ethereum Merkle Patricia Trie proofs. Proof verification logic must account for this. Proofs resolve across the supported store backends (classic IAVL, store/v2 memiavl, and other proof-capable queryable stores). As a result, the method works across a broader range of node configurations. See State Proofs.

Blocks and finality

Feature	Sei status	Notes
`eth_getBlockByHash`, `eth_getBlockByNumber`	Supported
`eth_blockNumber`	Supported
Finality tags (`latest`, `safe`, `finalized`)	Supported with differences	Sei has instant finality. All three tags refer to the same commitment level. See Finality.
Pending block state	Supported with differences	Sei does not guarantee Ethereum-style pending state visibility. Do not rely on pending transaction ordering. See Finality.

Logs, filters, and subscriptions

Feature	Sei status	Notes
`eth_getLogs`	Supported
Filter lifecycle (`eth_newFilter`, `eth_getFilterChanges`, `eth_getFilterLogs`, `eth_uninstallFilter`)	Supported
WebSocket subscriptions (`eth_subscribe`)	Supported	See WebSocket Connections.

Execution and simulation

Feature	Sei status	Notes
`eth_call`	Supported
`eth_estimateGas`	Supported
`debug_traceTransaction`	Supported
Block-level tracing	Supported

Signing

Feature	Sei status	Notes
EIP-155 replay protection	Supported
Personal sign (`personal_sign`, `eth_sign`)	Supported	Depends on whether the connected wallet exposes the method. See Signing.
EIP-712 typed data signing (`eth_signTypedData_v4`)	Supported	Depends on whether the connected wallet exposes the method. See Signing.
EIP-1271 contract signature validation	Supported	See Signing.

Token standards

Feature	Sei status	Notes
ERC-20	Supported
ERC-721	Supported
ERC-1155	Supported

Account abstraction

Feature	Sei status	Notes
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. You can deploy application-level name services as contracts.

Sei extensions

These features are specific to Sei and have no standard Ethereum equivalent. The @sei-js packages expose them as a layer on top of standard EVM tooling.

Feature	Notes
Sei precompiles (staking, governance, distribution, P256, JSON, Solo, pointers, and the CosmWasm bridge)	EVM contracts at deterministic addresses. `@sei-js/precompiles` exports the ABIs and contract addresses for use with any standard EVM library. It does not export the retired Oracle and disabled IBC precompiles.
Pointer contracts (CW20 ↔ ERC-20, CW721 ↔ ERC-721, CW1155 ↔ ERC-1155)	Bridge between CosmWasm and EVM token standards. Standard ERC interfaces work with pointer contracts. To look up a pointer, use `POINTERVIEW_PRECOMPILE_ADDRESS` (`0x…100A`). To register a pointer, use `POINTER_PRECOMPILE_ADDRESS` (`0x…100B`).
Native address association (EVM ↔ Cosmos address)	Links an EVM address and a Cosmos address for the same account. Some Sei-native flows require this association first.

Unsupported RPC methods

These JSON-RPC methods are not available on Sei or 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`	Sei does not support blob data availability endpoints.

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"`. On Sei, the pending nonce is the same as the confirmed nonce.
`eth_newPendingTransactionFilter`	You can create the filter, but it does 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 the results as best effort.

Proof verification

Method	Behavior on Sei
`eth_getProof`	Returns IAVL tree proofs, not Ethereum Merkle Patricia Trie proofs. The method works, but the proof format is not compatible with standard Ethereum MPT verifiers. See State Proofs.

Deprecated / removed opcodes

Method	Reason
`eth_accounts`	Returns an empty array on Sei RPC nodes. To get accounts from the connected user’s wallet, use a wallet library (`eth_requestAccounts`) instead.
