Retrieve all transactions sent to a specific address to track wallet activity, exchange flows, or smart contract interactions.
Use Case
Transaction queries help you:
- Track incoming transactions to wallets or exchanges
- Monitor smart contract interactions
- Analyze transaction patterns
- Build transaction history feeds
Code Example
curl --compressed -X POST 'https://portal.sqd.dev/datasets/ethereum-mainnet/stream' \
-H 'Content-Type: application/json' \
-d '{
"type": "evm",
"fromBlock": 18000000,
"toBlock": 18010000,
"fields": {
"block": {
"number": true,
"timestamp": true
},
"transaction": {
"hash": true,
"from": true,
"to": true,
"value": true,
"input": true,
"gasUsed": true,
"status": true
}
},
"transactions": [{
"to": ["0xdAC17F958D2ee523a2206206994597C13D831ec7"]
}]
}'
Try it yourself with the interactive query interface below:
Key Parameters
| Parameter | Description |
|---|
from | Filter transactions by sender address |
to | Filter transactions by recipient address |
sighash | Filter by function signature (first 4 bytes of input data) |
status | Transaction status: 1 = success, 0 = failure |
value | ETH amount transferred (in wei) |
input | Transaction calldata |
gasUsed | Actual gas consumed |
Expected Output
{
"header": {
"number": 18000123,
"timestamp": 1697544779
},
"transactions": [
{
"hash": "0x123...",
"from": "0xa9d1e08c7793af67e9d92fe308d5697fb81d3e43",
"to": "0xdac17f958d2ee523a2206206994597c13d831ec7",
"value": "0",
"input": "0xa9059cbb000000000000000000000000...",
"gasUsed": "54234",
"status": 1
}
]
}
Filter by Function Signature
Query only specific function calls (e.g., ERC-20 transfer function):
curl --compressed -X POST 'https://portal.sqd.dev/datasets/ethereum-mainnet/stream' \
-H 'Content-Type: application/json' \
-d '{
"type": "evm",
"fromBlock": 18000000,
"toBlock": 18010000,
"fields": {
"transaction": {
"hash": true,
"from": true,
"to": true,
"input": true
}
},
"transactions": [{
"to": ["0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"],
"sighash": ["0xa9059cbb"]
}]
}'
Function signature is computed as keccak256("transfer(address,uint256)")[0:4]. The result is 0xa9059cbb.
Monitor Outgoing Transactions
Track transactions from a specific wallet:
curl --compressed -X POST 'https://portal.sqd.dev/datasets/ethereum-mainnet/stream' \
-H 'Content-Type: application/json' \
-d '{
"type": "evm",
"fromBlock": 18000000,
"toBlock": 18010000,
"fields": {
"transaction": {
"hash": true,
"from": true,
"to": true,
"value": true
}
},
"transactions": [{
"from": ["0x28C6c06298d514Db089934071355E5743bf21d60"]
}]
}'
- Combine filters: Use both
from and to for bidirectional tracking
- Filter by sighash: Reduces results to specific function calls
- Request minimal fields: Omit
input if you don’t need calldata
- Check status: Filter failed transactions in post-processing if needed
