Description

Asana task

Migrates Thorchain swap endpoints off *.ninerealms.com — those hosts are being retired on 2026-04-20 (they already return 301). Without this change Thorchain swap quoting and the order-tracking link will break.

Changes:

• src/swap/defi/thorchain/thorchain.ts
  • orderUri: track.ninerealms.com/{TXID} → track.thorchain.org/{TXID} (same path format, tx lookups return 200)
  • THORNODE_SERVERS_DEFAULT[0]: thornode.ninerealms.com/thorchain → gateway.liquify.com/chain/thorchain_api/thorchain (Liquify's new primary endpoint)
• scripts/synchronizers/thorchain/thorchainSynchronizer.ts
  • Fallback Midgard server 0: midgard.ninerealms.com → gateway.liquify.com/chain/thorchain_midgard

Kept intact (intentional):

• ninerealmsClientId init option + x-client-id header — the new Liquify endpoints accept the header without issue; stripping it is a larger-surface config change for a separate PR.
• midgard.thorchain.info as a fallback — not on ninerealms.

Stagenet and thorchainrune currency / Savers endpoints are handled in the sibling PRs in edge-currency-accountbased and edge-react-gui.

Testing

Verified new endpoints with curl + existing ninerealmsClientId:

• gateway.liquify.com/chain/thorchain_api/thorchain/network → 200 OK
• gateway.liquify.com/chain/thorchain_midgard/v2/health → 200 OK
• track.thorchain.org/<txid> → 200 OK
• All *.ninerealms.com now return 301

Reviewer should confirm swap quotes + order tracker link open correctly on a mainnet Thorchain swap.

Note

Medium Risk
Endpoint changes affect swap quoting, order-tracking links, and mapping sync; risk is mostly around availability/compatibility of the new upstream hosts and any subtle URL/path differences.

Overview
Migrates the Thorchain swap plugin and Thorchain mapping synchronizer off retiring *.ninerealms.com hosts.

Updates the default Thornode API base URL to Liquify’s gateway, switches the order-tracking orderUri to track.thorchain.org, and replaces the synchronizer’s primary Midgard fallback with Liquify’s Midgard gateway. Adds a corresponding Unreleased changelog entry.
