LiFi¶

Connector for LiFi cross-chain bridge aggregation protocol.

almanak.framework.connectors.lifi ¶

LiFi Cross-Chain Aggregator Connector.

LiFi is a cross-chain liquidity meta-aggregator that routes through bridges (Across, Stargate, Hop, Wormhole, etc.) and DEXs (1inch, 0x, Paraswap, etc.) to find optimal routes for cross-chain and same-chain swaps.

This connector provides: - LiFiClient: SDK for interacting with the LiFi API - LiFiAdapter: Adapter for converting intents to LiFi transactions - LiFiReceiptParser: Parser for extracting results from transaction receipts

Supports both cross-chain bridges and same-chain swaps. Uses standard ERC-20 approvals (no Permit2 needed).

Example

from almanak.framework.connectors.lifi import LiFiClient, LiFiAdapter, LiFiConfig

config = LiFiConfig(chain_id=42161, wallet_address="0x...") client = LiFiClient(config)

Cross-chain swap: Arbitrum USDC -> Base USDC¶

quote = client.get_quote( from_chain_id=42161, to_chain_id=8453, from_token="0xaf88d065e77c8cC2239327C5EDb3A432268e5831", to_token="0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", from_amount="1000000000", from_address="0x...", )

Same-chain swap: Arbitrum USDC -> WETH¶

same_chain_quote = client.get_quote( from_chain_id=42161, to_chain_id=42161, from_token="0xaf88d065e77c8cC2239327C5EDb3A432268e5831", to_token="0x82aF49447D8a07e3bd95BD0d56f35241523fBab1", from_amount="1000000000", from_address="0x...", )

LiFiAdapter ¶

    config: LiFiConfig,
    price_provider: dict[str, Decimal] | None = None,
    allow_placeholder_prices: bool = False,
    token_resolver: TokenResolver | None = None,
)

Adapter for LiFi protocol integration with the Intent system.

This adapter converts high-level SwapIntents into executable transactions using the LiFi cross-chain aggregation protocol. Supports both same-chain swaps and cross-chain bridge+swap operations.

Features: - Cross-chain swap aggregation (bridge + DEX routing) - Same-chain DEX aggregation - Standard ERC-20 approval (no Permit2) - Deferred transaction pattern (fresh routes at execution)

Example

config = LiFiConfig(chain_id=42161, wallet_address="0x...") adapter = LiFiAdapter(config)

intent = SwapIntent( from_token="USDC", to_token="WETH", amount=Decimal("1000"), ) bundle = adapter.compile_swap_intent(intent)

LiFiReceiptParser ¶

LiFiReceiptParser(**kwargs: Any)

Parser for LiFi transaction receipts.

This parser extracts swap/bridge results from transaction receipts by: 1. Checking transaction status 2. Parsing ERC-20 Transfer event logs to find amounts 3. Identifying the wallet's sent and received amounts

For cross-chain transfers, amount_out reflects what was sent to the bridge on the source chain. The actual received amount on the destination chain must be checked via the LiFi status API.

Example

parser = LiFiReceiptParser() receipt = web3.eth.get_transaction_receipt(tx_hash)

result = parser.parse_swap_receipt( receipt=receipt, wallet_address="0x...", token_out="0x...", ) print(f"Sent: {result.amount_in}, Received: {result.amount_out}")

Initialize LiFiReceiptParser.

参数：

名称	类型	描述	默认
`**kwargs`	`Any`	Keyword arguments passed by the receipt_registry. chain: Chain name for token decimal resolution.	`{}`

parse_swap_receipt ¶

返回：

类型	描述

extract_bridge_data ¶

extract_bridge_data(

    token: str | None = None,
    amount: str | Decimal | None = None,
    bridge: str | None = None,
    expected_amount_out: str | Decimal | None = None,
) -> BridgeData | None

Extract typed BridgeData from a LiFi bridge receipt (VIB-3226).

LiFi is primarily a swap aggregator but also handles cross-chain transfers (via embedded bridge "tools" like Across, Hop, etc.). When a BRIDGE intent is routed through LiFi — or a SwapIntent is cross-chain — the Diamond proxy emits ERC-20 Transfers that move the wallet's tokens to the bridge facet. We use the first wallet->contract Transfer to derive amount_sent and the token.

Destination-chain settlement must be tracked via the LiFi status API — destination_tx_hash is intentionally None here.

extract_position_id ¶

extract_position_id(receipt: dict[str, Any]) -> int | None

LiFi swaps do not create LP positions.

extract_liquidity ¶

extract_liquidity(
    receipt: dict[str, Any],
) -> dict[str, Any] | None

LiFi swaps do not provide liquidity events.

extract_lp_close_data ¶

extract_lp_close_data(

extract_protocol_fees ¶

extract_protocol_fees(_receipt: dict[str, Any]) -> None

Placeholder for LiFi aggregator protocol-fee extraction (VIB-3204).

LiFi surfaces per-step fees in the quote response at compile time; receipts don't contain a uniform fee event. Threading the quote metadata into parser scope is deferred to a follow-up.

Follow-up ticket: "Protocol fee extraction for aggregators (Enso, LiFi) — follow-up to VIB-3204".

parse_approval_receipt ¶

parse_approval_receipt(
    receipt: dict[str, Any],

Parse an approval transaction receipt.

参数：

名称	类型	描述	默认
`receipt`	`dict[str, Any]`	Transaction receipt from web3	必需
