4x faster Transactions with EIP7702

We just enabled EIP7702 for server wallets, resulting in 4x faster sponsored transactions from sending to confirming when compared to ERC4337 execution.

How to use 7702 execution

Simply pass your server wallet EOA address (signer), execution will automatically default to EIP7702 execution and sponsor gas for the transaction.

curl -X POST "https://engine.thirdweb.com/v1/write/contract" \
  -H "Content-Type: application/json" \
  -H "x-secret-key: <your-project-secret-key>" \
  -d '{
    "executionOptions": {
      "from": "<your-EOA-server-wallet-address>",
      "chainId": "84532"
    },
    "params": [
      {
        "contractAddress": "0x...",
        "method": "function mintTo(address to, uint256 amount)",
        "params": ["0x...", "100"]
      }
    ]
  }'

You can also explicitly enable it by passing type: "EIP7702" in the execution options. Other execution types are "ERC4337" and "EOA".

If you pass your smart contract wallet address, by default engine will use ERC4337 execution like before, no changes needed.
