# Create Wallet > For the complete documentation index, see [llms.txt](/docs/llms.txt). POST https://api.g.alchemy.com/signer/v1/signup Enables the creation of a Smart Wallet using Alchemy Signer. It allows applications to authenticate users and facilitate signature operations on their behalf. A Smart Wallet is either an on-chain Modular Account with Alchemy Signer as the owner, a standalone EOA signer managed through Alchemy Signer, or a standalone Solana Wallet managed through the Alchemy Signer.
