Signet

Java 25 APIs for Bitcoin, EVM, TRON, Solana, TON, and XRP Ledger: accounts, balances, transaction preparation, signing, submission, blocks, and history.

Start building

1. Install dependencies and run your first read.
2. Connect your blockchain provider.
3. Create or import an account.
4. Prepare, sign, submit, and confirm a payment.

The developer documentation contains code examples directly on its pages, including imports and the assumptions for each operation.
