Batch EOA Execution for Server Wallets

We just enabled batch execution for EOAs, allowing you to execute multiple transactions atomically in a single call.
How to use batch execution
Simply pass multiple items in your params
array. All transactions will be executed atomically:
curl -X POST "https://engine.thirdweb.com/v1/write/transaction" \
-H "content-type: application/json" \
-H "x-secret-key: <your-secret-key>" \
-d '{
"executionOptions": {
"type": "EOA",
"chainId": "84532",
"from": "<your-eoa-address>"
},
"params": [
{
"to": "0x...",
"data": "0x...",
"value": "0x0"
},
{
"to": "0x...",
"data": "0x...",
"value": "0x0"
},
{
"to": "0x...",
"data": "0x...",
"value": "0x0"
}
]
}'
EOA Upgrade Required
Engine uses EIP7702 internally for batch execution, which requires your EOA to be "upgraded". If your EOA isn't already upgraded, you can send a no-op EIP7702 transaction to upgrade it:
curl -X POST "https://engine.thirdweb.com/v1/write/transaction" \
-H "content-type: application/json" \
-H "x-thirdweb-secret-key: <your-secret-key>" \
-d '{
"executionOptions": {
"type": "EIP7702",
"chainId": "84532",
"from": "<your-eoa-address>"
},
"params": [
{ "to": "<your-eoa-address>"}
]
}'
After this upgrade transaction, you can use batching with the same EOA.
Happy building! 🛠️
