External Matches

In addition to the standard darkpool flow -- deposit, place order, receive a match, then withdraw -- Renegade also supports external matches. An external match is a match between an internal party -- with state committed into the darkpool -- and an external party, with no state in the darkpool. Importantly, external matches are settled atomically; that is, the deposit, place order, match, withdraw flow is emulated in a single transaction for the external party.

An external match is generated and submitted on-chain by a client (see ExternalMatchClient). The client submits an ExternalOrder to the relayer to fetch a quote, and the relayer will attempt to match it against all consenting internal orders. If a match is found, the relayer will respond to the client with a quote containing:

• The match itself, specifying the amount and mint (ERC20 address) of the tokens bought and sold, fees, etc.
• A signature of the quote; which allows the client to authoritatively assemble the quote into a match bundle

If the client is satisfied with the quote, it can assemble the quote into a match bundle, which contains:

• The match itself, specifying the amount and mint (ERC20 address) of the tokens bought and sold
• An EVM transaction that the external party may submit in order to settle the match with the darkpool

The client should then submit this match to the darkpool.

Upon receiving an external match, the darkpool contract will update the encrypted state of the internal party, and fulfill obligations to the external party directly through ERC20 transfers. As such, the external party must approve the token they sell before the external match can be settled.

Example

The following snippet demonstrates how to request an external match, assemble the quote into a match bundle, and submit the bundle to the darkpool. See examples/external_match.py for a complete example.

from renegade import ExternalMatchClient
from renegade.types import AtomicMatchApiBundle, OrderSide, ExternalOrder

# Constants
BASE_MINT = "0xc3414a7ef14aaaa9c4522dfc00a4e66e74e9c25a"  # Testnet wETH
QUOTE_MINT = "0xdf8d259c04020562717557f2b5a3cf28e92707d1"  # Testnet USDC

# Create the client
api_key = os.getenv("EXTERNAL_MATCH_KEY")
api_secret = os.getenv("EXTERNAL_MATCH_SECRET")
client = ExternalMatchClient.new_sepolia_client(api_key, api_secret)

# Create the order
order = ExternalOrder(
    base_mint=BASE_MINT,
    quote_mint=QUOTE_MINT,
    side=OrderSide.SELL,
    quote_amount=30_000_000,  # $30 USDC
    min_fill_size=3_000_000,  # $3 USDC minimum
)

# Fetch a quote from the relayer
print("Fetching quote...")
quote = await client.request_quote(order)
if not quote:
    raise ValueError("No quote found")

# Assemble the quote into a bundle
print("Assembling quote...")
bundle = await client.assemble_quote(quote)
if not bundle:
    raise ValueError("No bundle found")

print(f"Received bundle: {bundle}")

Bundle Details

The quote returned by the relayer for an external match has the following structure:

• order: The original external order
• match_result: The result of the match, including:
• fees: The fees for the match
  • relayer_fee: The fee paid to the relayer
  • protocol_fee: The fee paid to the protocol
• receive: The asset transfer the external party will receive, after fees are deducted.
  • mint: The token address
  • amount: The amount to receive
• send: The asset transfer the external party needs to send. No fees are charged on the send transfer. (same fields as receive)
• price: The price used for the match
• timestamp: The timestamp of the quote

When assembled into a bundle (returned from assemble_quote or request_external_match), the structure is as follows:

• match_result: The final match result
• fees: The fees to be paid
• receive: The asset transfer the external party will receive
• send: The asset transfer the external party needs to send
• settlement_tx: The transaction to submit on-chain
  • tx_type: The transaction type
  • to: The contract address
  • data: The calldata
  • value: The ETH value to send

See example examples/quote_validation.py for an example of using these fields to validate a quote before submitting it.

This can be run with

uv run examples/quote_validation.py
