In the past decade, decentralized payments typically used EOA (Externally Owned Accounts) wallet solutions, including existing MPC solutions based on EOA wallet sharding. However, achieving fully decentralized payments without any custodial servers requires an all-contract solution for fund custody. The optimization of gas costs in full-contract solutions has been a core challenge for developers.

While full-contract solutions offer high security, optimizing their gas costs remains a core challenge for developers. This article will explore how to significantly reduce gas costs and promote the application of sub-contracts in real scenarios through contract factory template design and tight packing inline assembly solutions.

What is Secure Self-Custody?​

Secure self-custody is a fully smart contract-based solution for managing crypto assets. This solution allows merchants to have complete control over all crypto assets and permissions within their system without relying on any third-party servers or services. At the same time, it ensures multi-node security, preventing the loss of funds or data due to the compromise of a single point of authority.

When evaluating whether a solution meets the standard of secure self-custody, two key considerations must be addressed:
