Rent (Anchor)

Note

This is the Anchor v2 copy of this example. Every anchor command on this page needs the v2 CLI: cargo install anchor-cli --version 2.0.0-rc.2 --locked (avm has no prebuilt binary for this pre-release). The Anchor v1 version of this example is in ../anchor-v1.

Calculate account size and the minimum rent-exempt lamport balance.
