Server Wallets: New Features
- Spend Permissions: Enable EVM server wallets with smart accounts to delegate spend authorization within pre-set constraints (e.g., a set amount per time period) to other accounts.
- USD-based Wallet Policies: Set max transaction amounts in dollar terms, rather than expressed in native token amounts (e.g. deny transactions above $XX).
- Expanded SOL support: Wallet policy support on Solana, with address allowlisting and token values on SOL and SPL token transfers.
Onramp Onboarding: Update
- Existing and new customers are now required to complete lightweight developer onboarding within the CDP Portal to get full access to Coinbase Onramp & Offramp. Developers can complete this on their Developer Portal (Payments > Onramp & Offramp > Apply)
