2. Contract Configuration
Customize your contract with these parameters:
| Parameter | Description | Best Practice |
|---|---|---|
| Contract Name | Local storage only (not blockchain-persistent) | Keep backup records |
| Signer Information | Addresses and local notes (notes not blockchain-persistent) | |
| EVM Address Rules | Choose between: - New unique address - Cross-chain unified address | Recommended: Cross-chain unified addresses for security |
| Multi-signature Threshold | Minimum required signatures for transactions | Set ≥2 for shared custody |
Security Tip: Always add ≥2 signers and set threshold ≥2 for proper co-management.

III. FAQ
Q: Why can't I create a contract?
A: Check:
- Successful wallet connection
- Sufficient gas funds
Q: Why isn't my contract visible?
A: Potential reasons:
- Current wallet isn't a signer
- Contract still processing confirmations
Q: How long does contract creation take?
A: Varies by network congestion and confirmation requirements.
Q: Can I recover locally-stored data?
A: No - contract names and signer notes aren't blockchain-persistent. Always maintain external backups.
