# Nexian Gem & Genesis Immortals Mint

## Technical feats of the Nexian Gem & Genesis Immortals mint

***

### SeaDrop & Token standard

Smart contracts were built on top of OpenSea’s Seadrop token contracts, which in turn is based on the efficient ERC721A standard made popular by Azuki.

***

### Tamper-proofing token metadata

A provenance hash of all token metadata was written to each smart contract prior to start of mint. This is the gold-standard tamper proof method of ensuring token traits and ordering remains unchanged between mint and reveal.

***

### Random offset token IDs

Using an on-chain verifiable random number generated by Chainlink, the token start index will be randomly generated prior to reveal - the ultimate method of ensuring fair token ID allocation at reveal time.

***

### Novel 1-to-3 multi-token mint

3x Genesis Immortal mints were triggered from the Nexian Gem smart contract’s mint function eliminating the need for snapshots and off-chain Genesis Immortals distribution steps.
