Litecoin regtest/mainnet profiles, their activation limits and the planned multi-currency API. Network support is not live mainnet acceptance.

#Current development support

Available

Coinkun prepares public keysets from the configured Signer and issues account-owned addresses on the selected LTC regtest/mainnet network. A separately enabled confirmed-block scanner and mempool worker save matching outputs for History. Mainnet spending requires explicit opt-in and is disabled by default; real-chain acceptance is still pending. Regtest is a local testing network, not Litecoin mainnet.

Currency	Code	Network	Availability
Litecoin	ltc	regtest	Local development and acceptance tests
Litecoin	ltc	mainnet	Live acceptance pending; spending requires explicit opt-in

Important

History labels saved observations Pending, Not seen, Recorded or Orphaned. Absence is not cancellation, and a History observation is not an available balance. Scanners save receiving and spending observations. The normal scanner path reconciles stronger forks up to 6 blocks; deeper recovery uses durable bounded Replay while spending is blocked. The read-only CheckOutput/CheckOutputs diagnostics compare owned outputs with node evidence. Balance returns 503 on unknown evidence, never zero or partial funds. The Transfer API now estimates, reserves, signs and publishes up to 100 distinct transparent destinations using only owned inputs and change. A PostgreSQL-backed worker resumes unfinished payments; signed holds are not released after ambiguous publication. Dashboard review/send and mixed payment/receipt History are implemented. Multiple recipients, selected sources, percentages, All and proportional subtract-fee are supported. Regtest and offline mainnet checks do not establish production readiness; JWT and deferred modules are not implemented.

#Atomic units

Reference

Use whole atomic units for monetary values. For Litecoin, 100000000 litoshi equals one LTC. The integer 100000 therefore represents 0.001 LTC.

Whole LTC	Integer litoshi
1	100000000
0.001	100000
0.00000001	1

#Fiat currencies

Deferred

Fiat valuation and exchange-rate support are intentionally deferred. Coinkun does not currently offer fiat conversion or settlement.
