Seismic Python SDK — web3.py extensions for the Seismic privacy-enabled EVM
Project description
seismic-web3
Python SDK for Seismic, built on web3.py. Requires Python 3.10+.
pip install seismic-web3
Quick start
from seismic_web3 import SEISMIC_TESTNET, PrivateKey
pk = PrivateKey(bytes.fromhex("YOUR_PRIVATE_KEY_HEX"))
w3 = SEISMIC_TESTNET.create_client(pk)
contract = w3.seismic.contract(address="0x...", abi=ABI)
# Shielded write — calldata is encrypted (TxSeismic type 0x4a)
tx_hash = contract.write.setNumber(42)
receipt = w3.eth.wait_for_transaction_receipt(tx_hash)
# Shielded read — signed, encrypted eth_call
result = contract.read.getNumber()
ShieldedContract exposes five namespaces:
| Namespace | What it does | On-chain visibility |
|---|---|---|
.write |
Encrypted transaction (TxSeismic type 0x4a) |
Calldata hidden |
.read |
Encrypted signed eth_call |
Calldata + result hidden |
.twrite |
Standard eth_sendTransaction |
Calldata visible |
.tread |
Standard eth_call |
Calldata visible |
.dwrite |
Debug write — returns plaintext + encrypted views | Calldata hidden |
Both sync and async clients are supported. See the full documentation for details.
