Supported networks

All EVM networks supported by the solver rewards pipeline and their configurations.

The pipeline supports 10 EVM networks, each configured with its own token addresses, reward thresholds, and Dune blockchain name. The active network is selected via the NETWORK environment variable using the enum value shown in the table below.

The Network enum

src/config.py

class Network(Enum):
    """Network class for networks supported by the accounting."""

    MAINNET = "mainnet"
    BASE = "base"
    ARBITRUM_ONE = "arbitrum"
    BNB = "bnb"
    AVALANCHE = "avalanche"
    POLYGON = "polygon"
    GNOSIS = "gnosis"
    LINEA = "linea"
    PLASMA = "plasma"
    INK = "ink"

Set the NETWORK environment variable to the enum’s string value to select the target chain:

export NETWORK=mainnet   # Ethereum mainnet
export NETWORK=gnosis    # Gnosis Chain
export NETWORK=arbitrum  # Arbitrum One

Token addresses per network

Each network is configured with two key token addresses in PaymentConfig:

• wrapped_native_token_address — the wrapped version of the chain’s native gas token (e.g. WETH, WAVAX). Used to check whether a WETH unwrap must be prepended to the multisend transaction.
• wrapped_eth_address — the address of bridged/wrapped ETH on that chain. Used for price lookups via CoinPaprika.

The COW token address is only real on Ethereum mainnet (0xDEf1CA1fb7FBcDC777520aa7f396b4E015F497aB) and Gnosis Chain. On all other networks it is set to the dummy address 0x0000000000000000000000000000000000000006. This is intentional: COW token transfers are always executed on Ethereum mainnet regardless of which network is being processed, so the on-chain cow_token_address for non-mainnet networks is never used in actual ERC-20 calls.

COW transfers always happen on Ethereum mainnet

The pipeline maintains two separate Safe transactions per payout run: one for native token transfers on the target network, and one for COW token transfers — the latter is always posted to Ethereum mainnet, even when processing rewards for Gnosis Chain, Arbitrum, or any other network. This means the pipeline requires a mainnet node URL (NODE_URL_MAINNET) in addition to the target-chain node URL (NODE_URL).

From src/fetch/transfer_file.py:

src/fetch/transfer_file.py

nonce_cow = post_multisend(
    safe_address=config.payment_config.payment_safe_address_cow,
    transactions=transactions_cow,
    network=EthereumNetwork.MAINNET,   # always mainnet
    signing_key=signing_key,
    client=client_mainnet,
    nonce_modifier=config.payment_config.nonce_modifier,
)

Nonce modifier system

Because the pipeline proposes COW transfers for all supported networks via the same Ethereum mainnet Safe, it needs to queue multiple transactions without nonce conflicts. The nonce_modifier_dict assigns each network a unique offset from the current Safe nonce:

src/config.py

nonce_modifier_dict = {
    network: idx for idx, network in enumerate(reversed(list(Network)), start=0)
}
nonce_modifier = int(
    os.environ.get(
        "NONCE_MODIFIER",
        nonce_modifier_dict[network],
    )
)

This iterates the Network enum in reverse order and assigns start=0 to the last network (INK), incrementing toward MAINNET. The result is a stable, deterministic offset for each network’s mainnet COW transaction.

The NONCE_MODIFIER environment variable can override the computed value if a specific offset is needed (for example when re-running a failed proposal).

For mainnet itself, native transfers are also posted to mainnet. To avoid a second nonce conflict between the COW transaction and the native transaction, the native-transfer call uses nonce_modifier=len(Network) — one slot beyond the last COW-transfer slot.
