Secret Network is the Layer-1 blockchain upon which Sienna Network (Layer-2 protocol) was developed. The SIENNA token was developed using the Secret Network SNIP-20 standard. Gas fees for transactions are paid in native SCRT tokens—similar to how Layer-2 protocols on Ethereum use ETH for gas fees.
How do I acquire SCRT?
Currently there are 3 distinct options for acquiring SCRT:
Centralized Exchanges: SCRT is available on Binance, BitKub, MEXC Global, Gate.io, CoinEx, Hotbit. This will give you native SCRT directly.
Decentralized Exchanges: SCRT is available on Osmosis.
Asking for some SCRT in the Sienna/Secret Telegram groups.
Please note that SCRT is not private and does not have the privacy preserving features of the SNIP-20 tokens on Secret Network (e.g. SIENNA). So you will want to consider how to send SCRT between wallets if you do not want them to be linked by on-chain data.
