Direct burn-and-close SDK

For the server-side Wallet API client, use @unclaimedsol/wallet-sdk and the partner preview guide.

@unclaimedsol/spl-burn-close-sdk is the separate package for building transactions for the Unclaimed burn-and-close program. It is not the wallet analysis API client.

npm install @unclaimedsol/spl-burn-close-sdk

Follow the version-specific package documentation and source repository for its transaction-building contract.

Your application remains responsible for explicit user consent, wallet signing, submission and confirmation. Burning is permanent; recovered rent is not the market value of the burned asset.
