Here is my conversation with 0age: intothebytecode.xyz/0age-seaport/

0age is the Head of Protocol Development at OpenSea, and this was a conversation about Seaport, the new marketplace protocol for buying and selling NFTs.

0age takes us through a tour of the Seaport protocol, talking about how it's architected; how conduits and zones work; and we even get into the low level gas optimization work they've done on the contracts. I hope this can be a helpful resource for anyone looking to understand the Seaport protocol or anyone who's building with NFTs more broadly. I also consider 0age to be a true veteran of the space, and hearing him talk through the design of the protocol can be an educational experience in its own rights. I definitely personally found that to be the case.

I hope you enjoy!
