filter_scams(pairs_df, client, min_token_sniffer_score=65, drop_token_tax=False)[source]#

Filter out scam tokens in pairs dataset and print some stdout diagnostics.

TODO: Work in progress.

Example:

# Scam filter using TokenSniffer
pairs_df = filter_scams(pairs_df, client, min_token_sniffer_score=Parameters.min_token_sniffer_score)
pairs_df = pairs_df.sort_values("volume", ascending=False)

print("Top pair matches (including benchmark pairs):")
for _, pair in pairs_df.head(10).iterrows():
    print(f"   Pair: {pair.base_token_symbol} - {pair.quote_token_symbol} ({pair.exchange_slug})")

uni_v2 = pairs_df.loc[pairs_df["exchange_slug"] == "uniswap-v2"]
uni_v3 = pairs_df.loc[pairs_df["exchange_slug"] == "uniswap-v3"]
print(f"Pairs on Uniswap v2: {len(uni_v2)}, Uniswap v3: {len(uni_v3)}")

dataset = load_partial_data(
    client=client,
    time_bucket=Parameters.candle_time_bucket,
    pairs=pairs_df,
    execution_context=execution_context,
    universe_options=universe_options,
    liquidity=True,
    liquidity_time_bucket=TimeBucket.d1,
)
