# 3. Check Deterministic Deployment Proxy
# 3. Test Pectra (EIP-7702 / EIP-2537 / Solc 0.8.29+ with evm_version=prague)
# Init code: STATICCALL the BLS12-381 G1ADD precompile (EIP-2537, bundled
# in Pectra alongside EIP-7702) with 256 bytes of zeros (G1 point at infinity
# + G1 point at infinity = point at infinity, returns 128 bytes). Return one
# byte: 0x01 if returndatasize > 0 (precompile active), else 0x00.
# PUSH2 0x80 out_size = 128
# PUSH1 0x00 out_offset
# PUSH2 0x100 in_size = 256
# PUSH1 0x00 in_offset
# PUSH1 0x0b addr = BLS12_G1ADD precompile
# PUSH2 0xffff gas
# STATICCALL consumes 6 stack items, pushes success flag
# POP discard success flag
# RETURNDATASIZE
# ISZERO ISZERO normalize returndatasize > 0 to 0x01, else 0x00
# PUSH1 0x00 MSTORE8
# PUSH1 0x01 PUSH1 0x00 RETURN
# This is technically a Prague-activation test: EIP-2537 (BLS precompiles)
# and EIP-7702 (set-EOA-code) ship in the same hardfork, so a positive signal
# here implies 7702 is also enabled. A direct 7702 test would require sending
# a signed type-4 transaction, which precheck can't do without a private key.
