I passed through Sofia Airport in Sofia, Bulgaria in 2026, and I got to mint this pretty POAP! SOF opened in the 1930s, and has grown a lot over the years. It's pretty close to the city center, so its a convenient gateway to explore Bulgaria's capital and beyond. This POAP was minted in 2026 as part of a campaign to offer precious digital collectibles to travellers around the world.
