ERC-8010 Demo

Walk through the complete pre-delegation signature verification flow.

1. Sign Message

2. Wrap with ERC-8010

3. Verify Off-Chain

4. Delegate On-Chain

5. Verify Post-Delegate

Step 1: Sign a Message

Pending

Sign a message with the preset account. This signature will later be verified by the delegated contract.

Message to sign

Step 2: Wrap with ERC-8010

Pending

Sign an EIP-7702 authorization with the preset account and build the ERC-8010 wrapped signature: inner_sig || context || context_len || MAGIC.

Step 3: Verify Off-Chain (Pre-delegation)

Pending

Verify the wrapped signature using viem's verifyHash. It auto-detects the MAGIC marker and simulates delegation via eth_call.

Step 4: Execute Delegation On-Chain

Pending

Send a type-4 transaction with the EIP-7702 authorization list. This sets the EOA's code to 0xef0100 || delegate.

Step 5: Verify Post-Delegation

Pending

Verify the same wrapped signature again. Now that delegation is on-chain, viem detects the delegation code and uses ERC-1271 directly — no simulation needed.
