Securities are shares, bonds, promissory notes and other transferable securities, and they are registered by the ERIR. The participatory loan is a contract and does not go through the ERIR.

What it means for your issuance.

The ERIR only registers securities on the networks it supports and with the smart contracts it has reviewed. HokenFi works with it on Ethereum and Polygon.

Participatory loan? Any EVM network.

Each contract is direct between the investor and your company, and is recorded as proof. As it does not go through the ERIR, the entry can be on Ethereum, Polygon or any other EVM-compatible network.

Questions

What beginners usually ask.

Why does the network depend on the ERIR?

Because Ursus-3 Capital only registers securities on the networks it supports and with contracts it has accepted for registration. Without that, it cannot register them.

When will Solana and ISBE be available?

It depends on the ERIR admitting them, and there is no date yet.

What is ISBE?

The Spanish Blockchain Services Infrastructure, a network designed for companies and public administrations and built on Ethereum-compatible technology.

On which network is my participatory loan?

Today, on Ethereum or Polygon. We are preparing Solana and other EVM-compatible networks. As it does not go through the ERIR, it does not depend on the networks it admits.
