Batch Operations
This endpoint supports batch operations, allowing you to read multiple contract methods in a single API call.Batch Request Format
To execute multiple reads, use thecalls array:
{
"calls": [
{
"address": "0x1234...",
"method": "balanceOf",
"parameters": ["0xabcd..."],
"abi": [...]
},
{
"address": "0x5678...",
"method": "totalSupply",
"parameters": [],
"abi": [...]
}
]
}
Batch Response Format
Batch responses includesuccess and errors arrays:
{
"message": "Batch contract read completed (2/2 successful)",
"statusCode": 200,
"data": {
"success": [
{ "index": 0, "method": "balanceOf", "data": "1000000" },
{ "index": 1, "method": "totalSupply", "data": "50000000" }
],
"errors": []
}
}
Validation Rules
| Rule | Value |
|---|---|
| Max batch size | 20 operations |
| Min batch size | 1 operation |
Use Cases
- Bulk reads: Read multiple contract states efficiently
- Multi-asset balances: Query balances across multiple assets in one call
- Protocol state: Read multiple protocol parameters simultaneously
