Charge payments are the simple MPP path: the client signs an ERC-3009 authorization and the server settles it on-chain.

1. Install the package

2. Register the server method

The Abstract package exposes a server-side charge method under @abstract-foundation/mpp/server.

3. Create the client method

The client signs the authorization but does not broadcast a transaction directly.

4. What the request needs

The charge request includes:
  • amount
  • currency
  • decimals
  • recipient
  • optional chainId
On Abstract, the normal token path is USDC.e with 6 decimals.

5. When to use charge mode

Use charge mode when:
  • the client makes isolated requests
  • you want no channel lifecycle
  • the simplicity of one signature per request is acceptable

Move to Session Payments if the same client will hit your API repeatedly.
