Benchmarks

Gas cost of the transaction when transfering 5 tokens. Note: this is not 100% accurate.

• Those values are not 100% accurate but they are close enough
• The benchmarks are made using the OpenZeppelin ERC721 contract. If you use ERC721A for example, the amount of gas used will be very different.
