Secret has integrations with the following wallets:
Keplr
Leap
Fina.Cash (mobile friendly)
Starshell (added privacy)
Metamask (only signing, not SCRT storage)
Cosmostation
Citadel.One
You can check out app.shadeprotocol.io or dash.scrt.network to try out these various wallets. Documentation for wallet integration is available here: https://docs.scrt.network/secret-network-documentation/development/frontend/templates/usage-examples/wallet-integrations
Secret Network is the only non-EVM cosmos chain that supports native Metamask signing! It is an awesome onboarding tool for new users or can be the missing tool to have people use Secret in your Privacy as a Service flow without ever needing a 2nd wallet or other gas.
