FAQ
What people ask me most.
Short answers. Each resource goes into the details.
Who is behind soyguille.com?
Me, Guille (Guillermo Cámara Castillo, @aguille_). I'm the Hedera ambassador in Spain, I handle business development and marketing at SentX and I'm the founder of Hashly. I've been in blockchain for more than 5 years and I make Spanish-language content about tokenization, NFTs and digital communities.
What is Hedera?
A public blockchain network, like Ethereum or Solana. It's governed by a council of large companies, including Google and IBM, and its currency is HBAR. On this site I explain how it works under the hood and what's being built on it.
What is CLPR?
CLPR (pronounced "clipper") is a protocol that lets two blockchains send each other messages directly, with no bridge in between. Each message travels with a cryptographic proof and the receiving network checks it itself. It was created by Hashgraph, the team behind Hedera, and since September 2026 it's open source at the Linux Foundation. There's an interactive guide in three levels: basic, intermediate and technical.
How does an NFT-backed loan work on CollaFi?
One wallet offers HBAR and another accepts by putting up an NFT as collateral, which is held in escrow. The borrower has a set period to repay the principal plus interest. If they repay, they get the NFT back; if not, the loan goes into default and the lender can claim the NFT. The simulator walks through it step by step with the real Dead Pixels Ghost Club fees.
What are SentX and Hashly?
SentX is the main NFT marketplace on Hedera, where the network's NFTs are created, bought and sold. Hashly is the platform to discover Hedera projects, with a launch calendar, rankings and community voting. At SentX I handle business development and marketing, and I founded Hashly.
Are the resources free?
Yes. The simulators and guides are free and you don't need an account.
Is this investment advice?
No. I explain how things work and who is using them. I don't tell anyone what to invest in and I don't talk about prices.
How can I contact you?
The fastest way is X (@aguille_) or LinkedIn. If it's for a project or a company, you can book a call from the site.
