Falcon Sign SDK
Falcon PL is a testnet. FPL testnet tokens have no monetary value and cannot be bought or sold. Paid plans pay for RPC capacity and support only.
Coming soon
A client SDK for building, Falcon-512 signing and submitting Falcon PL transactions. It will be released as open source under the Apache-2.0 licence.
Until then, use the RPC gateway and the Explorer API.
