EVM Behavior

Signet is the most EVM-compatible rollup. This page describes the (very few) differences between Signet and Ethereum Mainnet EVM behavior.

Inherited header values

The following opcodes inherit the values of the Ethereum block:

• PREVRANDAO - block.difficulty and block.prevrandao
• TIMESTAMP - block.timestamp.Signet blocks ALWAYS use the same timestamp as the current Ethereum block.

Disabled Opcodes

The following opcodes are disabled in Signet:

• BLOBHASH - eip-4844 is not supported.
• BLOBBASEFEE - eip-4844 is not supported.

Precompiles

Signet supports the same precompiles as ethereum, plus the following additional precompile:

• secp256r1 signature verification as specified in RIP-7212 at address 0x100.
