This morning, a16z Crypto shared some tools and proofs of concept built by the organization through their official Twitter, covering various fields such as zero-knowledge proofs, contract security, and decentralization. These tools and concepts are primarily aimed at developers who continue to work tirelessly during the long bear market. Interested friends might as well give them a try.
Below is the full text from a16z's Twitter.
We are excited to see many exciting new ideas emerging in the crypto community. In the following tweets, you will find some development tools that can help you continue to build.
The purpose of sharing these tools and proofs of concept is to demonstrate to the community how to use the latest technological primitives in development and production, and to accelerate the adoption of these technological primitives through more developers.
Zero-Knowledge Proofs
1. zkDocs
zkDocs can be understood as an online document tool that supports zero-knowledge proofs. It allows parties involved in a workflow to collectively share and verify information while ensuring that the information meets specific standards without exposing those standards.

2. Privacy-protecting Airdrops
As the name suggests, this is a privacy protection tool for airdrop scenarios. We created this tool to use zero-knowledge proofs to protect ordinary users, improving security by enhancing privacy during airdrops.

Contract Security
1. ERC 4626 Property Tests
This is a tool for detecting the executability of contracts under ERC 4626 (a standard for tokenized vaults), helping vault builders identify potentially destructive or vulnerable violations of standards.

GitHub link: https://github.com/a16z/erc4626-tests
2. Metamorphic Smart Contract Detector
This is a tool for detecting metamorphic smart contracts, which can resist attacks initiated by changing the content of smart contracts.
Some smart contracts can still be changed after deployment, meaning developers can alter the code at any time, posing a serious threat to users. This tool allows anyone to easily check whether a specific smart contract has the potential for changes.

Decentralization & Power Distribution
1. Ethereum Light Client Helios
This is an Ethereum light client based on the Rust language, which helps further promote the decentralization of Ethereum. Helios provides completely trustless access to the Ethereum blockchain without the need to store historical transaction information, allowing data access to be completed in just 2 seconds when needed.

2. Trustless, on-chain Auctions
This is an on-chain implementation of the "Vickrey auction." A "Vickrey auction" refers to a bidding process where all bidders submit sealed bids, and the highest bidder wins the item, paying the second-highest bid.
The underlying principle of this tool is that Ethereum's CREATE 2 opcode allows the bidding content to be hidden within blockchain activities.

3. Trusted Setups
We have open-sourced a codebase that allows anyone to implement the Kate-Zaverucha-Goldberg (KZG) and powers-of-tau "ceremony" on the Ethereum chain (Note: this refers to the trusted initialization of parameters required for data availability proof schemes).
