Develop & Build
For the builders in the community
You don't need to be a developer to invest, but understanding how the ledger is built makes you much harder to fool.
Start with the docs
xrpl.org is the canonical reference: transaction types, account settings, amendments and tutorials in several languages.
Test before you touch mainnet
The XRPL Testnet and Devnet give you free test XRP so you can practise transactions with zero financial risk.
Builder tools and learning resources
Everything you need to go from reading the ledger to shipping on it — most of it free and open source.
