# Prepare a Solana wallet transfer

`POST /api/v1/deposits/prepare`

## Request

- URL: `https://spoofy.social/api/v1/deposits/prepare`

  - HTTP bearer
  - API key in cookie `better-auth.session_token`

The unsigned Solana transaction that pays `amount` (USD; 1 coin = $1) of the method’s coin from the wallet `from` to your own Solana deposit address: it creates the receiving token account if needed, then transfers. Your wallet signs and sends it (Wallet Standard `solana:signAndSendTransaction`); then pass its signature to `POST /deposits/check`. Nothing is signed or sent by Spoofy. On EVM networks, send an ERC-20 `transfer` to your address yourself.
