## Summary Adds Jumpcoin (JUMP), a Proof-of-Stake UTXO coin, to the AtomicDEX coins database. ## Files Changed - coins: JUMP entry with protocol parameters - electrums/JUMP: ElectrumX servers (TCP + SSL) - explorers/JUMP: Block explorer URL - utils/JUMP.json: Configuration file - api_ids/: CoinGecko, CoinPaprika, LiveCoinWatch IDs - icons_original/jump.png: Coin icon ## Coin Parameters - Type: UTXO (Proof-of-Stake) - RPC Port: 31240 - Derivation Path: m/44'/278' - Confirmations: 5 - Block Time: 60s ## Electrum Servers - electrum1.jumpcoin.net:50001 (TCP) - electrum1.jumpcoin.net:50002 (SSL) ## Apology I sincerely apologize for the previous versions of this PR which: 1. Accidentally moved LTC's rpcport field 2. Modified whitespace/formatting of JKC and OSMO-IBC entries in livecoinwatch_ids.json 3. Removed trailing newlines from API ID files These unintended changes to other coins/projects were unacceptable. This version only adds JUMP without modifying any existing entries. Thank you @cipig for the review feedback.
- Remove JUMP from coingecko_ids.json (not listed on CoinGecko) - Change livecoinwatch ID from 'JUMP' to '_JUMP' (prefix required to distinguish from other JUMP coins) - Keep coinpaprika as 'jump-jumpcoin' (verified correct)
- Added wss://electrum1.jumpcoin.net:50003 (WebSocket Secure) - SSL cert: Let's Encrypt R12 (valid until 2026-07-01) - Server: Oracle Cloud VPS, jumpcoin-electrum-proxy service active
