EVM Compatibility

BESC Hyperchain runs a fully up-to-date Ethereum Virtual Machine. All Ethereum hardforks through Cancun are active from genesis block 0, meaning every EIP in the Cancun specification is available from the very first block.

Active Hardforks

Hardfork	Active Since	Key EIPs
Berlin	Block 0	EIP-2929 (gas cost increases), EIP-2930 (access lists)
London	Block 0	EIP-1559 (fee market), EIP-3198, EIP-3529, EIP-3541
Shanghai	Block 0	EIP-3651, EIP-3855 (PUSH0 opcode), EIP-3860, EIP-4895
Cancun	Block 0	EIP-1153 (transient storage), EIP-5656 (MCOPY), EIP-6780 (SELFDESTRUCT), EIP-4844 (blob txs)

Solidity Compatibility

Every version of Solidity is supported. You can deploy contracts compiled with any optimizer setting, any pragma solidity version, and any EVM target up to cancun.

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.24;

// This contract deploys identically on BESC Hyperchain and Ethereum
contract HelloBESC {
    string public message = "Hello from BESC Hyperchain";
    uint256 public chainId = block.chainid; // returns 2372

    function update(string calldata _msg) external {
        message = _msg;
    }
}

Precompiles

All standard Ethereum precompiles are available at their canonical addresses:

Address	Precompile
0x01	ecRecover
0x02	SHA2-256
0x03	RIPEMD-160
0x04	identity
0x05	modexp
0x06	ecAdd (BN254)
0x07	ecMul (BN254)
0x08	ecPairing (BN254)
0x09	BLAKE2b
