AI Index Baskets (Trend Cards)

Tokenized, ETF-like on-chain index funds. Each AIB is its own mainnet ERC-20 share token (AIB-<SYM>, e.g. AIB-AA208630); shares mint against on-chain basket backing at NAV and are withdrawable on-chain.

# Discover live Trend Cards
cards = await client.aib.list_trend_cards()

# Definition, live NAV, issuance quote, real-time iNAV
info  = await client.aib.get("AIB-AA208630")
nav   = await client.aib.nav("AIB-AA208630")
quote = await client.aib.quote("AIB-AA208630")   # ask=mint@NAV+spread, bid=redeem@NAV-fee
inav  = await client.aib.inav("AIB-AA208630")     # + premium/discount vs market price

# Buy shares (pay USDC, mint at NAV+spread) and check your holdings
order = await client.aib.buy("AIB-AA208630", "100")   # spend 100 USDC
mine  = await client.aib.holdings()                    # non-zero AIB share balances

# Sell to in-platform USDC ...
await client.aib.sell("AIB-AA208630", 50)
# ... or redeem for an ON-CHAIN USDC payout to your own address
await client.aib.redeem("AIB-AA208630", 50, destination_address="0xYourAddress")

# Secondary market: trade shares on the CLOB with the AIB-<SYM> symbol
book = await client.clob.orderbook("AIB-AA208630")

Streaming

# Stream order book updates
async for update in client.streaming.orderbook("0x...", "BTC"):
    print(f"Spread: {update.spread}")

# Private WebSocket (user orders and fills)
async for update in client.streaming.private(token="your_jwt"):
    if update.channel == "userOrders":
        print(f"Order update: {update.data}")
    elif update.channel == "userFills":
        print(f"Fill: {update.data}")

CLOB Streaming (Settlement Notifications)

from event_trader.streaming.clob import CLOBStream

stream = CLOBStream(config, channels=["userFills", "balanceUpdate"], token="jwt_token")

# Settlement status notifications — get alerted to delays
def on_settlement(data):
    status = data.get("settlement_status")
    if status == "settled":
        print(f"Settled on-chain: {data['explorer_url']}")
    elif status == "delayed":
        print(f"Settlement delayed ({data['delay_seconds']}s) — ETA: {data['estimated_completion']}")
    elif status == "failed":
        print(f"Settlement failed — funds will be refunded automatically")

stream.on_settlement(on_settlement)
stream.on_fill(lambda data: print(f"Fill: {data}"))
stream.on_balance(lambda data: print(f"Balance changed"))

async for event in stream:
    pass  # Callbacks fire automatically

Settlement Status Flow

Orders settle in the background after matching. The WebSocket settlement_update event reports progress:

Status	Meaning	Fields
settled	On-chain swap confirmed	tx_hash, explorer_url, chain
delayed	Settlement taking longer than expected	delay_seconds, retry_count, estimated_completion
failed	Settlement failed after retries	reason (internal — use generic message for users)

Typical settlement time: 10-30 seconds. Maximum: 90 seconds per attempt, up to 3 retries.

Error Handling

from event_trader import (
    EventTraderError,
    AuthenticationError,
    RateLimitError,
    NotFoundError,
    InsufficientFundsError,
    OrderError,
)

try:
    order = await client.trading.place_order(...)
except InsufficientFundsError:
    print("Not enough balance")
except RateLimitError as e:
    print(f"Rate limited, retry after {e.retry_after}s")
except NotFoundError:
    print("Market not found")
except OrderError as e:
    print(f"Order failed: {e}")
except EventTraderError as e:
    print(f"SDK error: {e}")

    api_key="evt_...",
    base_url="https://cymetica.com",
