seismic-web3 0.2.0

Seismic Python SDK — web3.py extensions for the Seismic network

seismic-web3

Python SDK for Seismic, built on web3.py. Requires Python 3.10+.

pip install seismic-web3

Client types

The SDK provides two client types:

• Wallet client — you provide a private key. Gives you full capabilities: shielded reads/writes, signed calls, deposits.
• Public client — no private key needed. Read-only access via transparent eth_call.

Quick start

import os
from seismic_web3 import SEISMIC_TESTNET, PrivateKey

pk = PrivateKey.from_hex_str(os.environ["PRIVATE_KEY"])

# Wallet client — full capabilities (requires private key)
w3 = SEISMIC_TESTNET.wallet_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()

# Public client — read-only (no private key needed)
public = SEISMIC_TESTNET.public_client()

contract = public.seismic.contract(address="0x...", abi=ABI)
result = contract.tread.getNumber()

ShieldedContract (from the wallet client) 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.
