6. Stellar Wallet via Cubist

Use Cubist to create secure wallets for Stellar. These wallets are used to sign and pay for gas for any on-chain interactions (writes).

• Create wallet in the Cubist integration panel

• Once created, it’s available for use in Write to Smart Contract

Cubist benefits:

• Hardware-backed key security

• Seamless gas management

• No external signing or extensions needed
