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.
