#BuiltonSolayer As of now, there is no widely recognized blockchain called "Solayer", so the term may refer to one of these possibilities:

1. Name of a new project or emerging blockchain (similar to Solana, LayerZero, etc.).

2. A layer solution (Layer) based on Solana – a second layer network or protocol built on Solana.

3. A typographical error of "Built on Solana" or "Built on LayerX" (for example, Ethereum Layer 2, etc.).

Possible interpretations of the hashtag:

#BuiltonSolayer: Projects developed on a protocol or layer called Solayer.

It may be related to innovation in blockchain infrastructure, scalability, or DeFi/NFT/gaming on a specific network.

If it is a new marketing narrative, it could be part of a launch campaign.
