-- Recent data
WHERE block_number >= (SELECT MAX(block_number) - 1000 FROM fact_blocks)

-- Historical analysis
WHERE block_number BETWEEN 15000000 AND 16000000

-- Join across tables
JOIN <blockchain_name>.core.fact_event_logs USING (block_number)

-- Time-based filtering (most efficient)
WHERE block_timestamp >= DATEADD('day', -7, CURRENT_TIMESTAMP)

-- Hourly aggregations
DATE_TRUNC('hour', block_timestamp) AS hour

-- UTC date extraction
DATE(block_timestamp) AS block_date

-- Find all event types for a contract
SELECT DISTINCT event_name, COUNT(*) as occurrences
FROM ez_decoded_event_logs
WHERE contract_address = LOWER('0x...')
GROUP BY 1
ORDER BY 2 DESC;
``` |
| EVENT_INDEX | NUMBER | Zero-based sequential position of the event within a transaction's execution.

**Key Facts**:
- Starts at 0 for first event
- Increments across all contracts in transaction
- Preserves execution order
- Essential for deterministic event ordering

**Usage Example**:
```sql
-- Trace event execution flow
SELECT
    event_index,
    contract_address,
    topic_0,
    SUBSTRING(data, 1, 10) AS data_preview
FROM <blockchain_name>.core.fact_event_logs
WHERE tx_hash = '0xabc...'
ORDER BY event_index;

| ORIGIN_FUNCTION_SIGNATURE | TEXT | Function signature (first 4 bytes) of the called method.

**Format**: 0x + 8 hex characters

**Common Signatures**:
- 0xa9059cbb: transfer(address,uint256)
- 0x095ea7b3: approve(address,uint256)
- 0x23b872dd: transferFrom(address,address,uint256)

**Note**: NULL for simple transfers or invalid calls |
| ORIGIN_FROM_ADDRESS | TEXT | The externally-owned account (EOA) or contract address that initiated the transaction.

**Key Points**:
- Always 42 characters (0x + 40 hex chars)
- Lowercase normalized in all tables
- Cannot be NULL for valid transactions
- For contract creation: sender of creation transaction

**Common Patterns**:
- EOA → EOA: Simple transfer
- EOA → Contract: User interaction
- Contract → Contract: Internal calls (see fact_traces)
- Known addresses: Exchange hot wallets, protocol deployers

**Query Examples**:
```sql
-- User activity analysis
SELECT from_address, COUNT(*) as tx_count
FROM <blockchain_name>.core.fact_transactions
WHERE block_timestamp >= CURRENT_DATE - 30
GROUP BY 1
ORDER BY 2 DESC;

-- New user detection
SELECT DISTINCT from_address
FROM <blockchain_name>.core.fact_transactions t1
WHERE NOT EXISTS (
    SELECT 1 FROM <blockchain_name>.core.fact_transactions t2
    WHERE t2.from_address = t1.from_address
    AND t2.block_number < t1.block_number
);
``` |
| ORIGIN_TO_ADDRESS | TEXT | The destination address for the transaction - either an EOA or contract address.

**Special Cases**:
- NULL: Contract creation transaction
- Contract address: Interacting with smart contract
- EOA address: Simple transfer or receiving funds

**Important Patterns**:
```sql
-- Contract deployments
WHERE to_address IS NULL

-- Popular contracts
SELECT to_address, COUNT(*) as interactions
FROM <blockchain_name>.core.fact_transactions
WHERE to_address IS NOT NULL
GROUP BY 1
ORDER BY 2 DESC;

-- Direct transfers only
WHERE to_address NOT IN (SELECT address FROM dim_contracts)

-- Check data latency
SELECT
    DATE_TRUNC('hour', block_timestamp) as block_hour,
    DATE_TRUNC('hour', inserted_timestamp) as insert_hour,
    AVG(TIMESTAMPDIFF('minute', block_timestamp, inserted_timestamp)) as avg_latency_minutes
FROM <blockchain_name>.core.fact_transactions
WHERE block_timestamp >= CURRENT_DATE - 1
GROUP BY 1, 2;
``` |
| MODIFIED_TIMESTAMP | TIMESTAMP_NTZ | UTC timestamp of the most recent update to this record.

**Format**: TIMESTAMP_NTZ

**Triggers for Updates**:
- Data corrections
- Enrichment additions
- Reprocessing for accuracy
- Schema migrations

**Monitoring Usage**:
```sql
-- Recently modified records
SELECT *
FROM <blockchain_name>.core.fact_transactions
WHERE modified_timestamp > inserted_timestamp
AND modified_timestamp >= CURRENT_DATE - 1;

-- Data quality tracking
SELECT
    DATE(modified_timestamp) as mod_date,
    COUNT(*) as records_updated,
    COUNT(DISTINCT block_number) as blocks_affected
FROM <blockchain_name>.core.fact_transactions
WHERE modified_timestamp > inserted_timestamp
GROUP BY 1
ORDER BY 1 DESC;
