Description

Asana task

Consolidates the two open partner PRs that add Rango DEX support for new chains:

• feat: add sui to rango #438 — feat: add sui to rango
• feat: add sonic to rango #439 — feat: add sonic to rango

While preparing this consolidation, all of #438's Sui changes were found to be already present in master (the rfc4648 import, the asSuiTransaction cleaner, the case 'SUI' swap handler, and rango.set('sui', 'SUI') — shipped in 2.44.0, "(Rango) SUI support"). master's version of the Sui handler is a refactor of #438's that returns { ...swapOrderBase, makeTxParams } and adds orderUri to the saved action, so it supersedes #438.

The only net-new change versus master is #439's one-line mapping for Sonic:

• rango.set('sonic', 'SONIC') in src/mappings/rango.ts (previously null).

No fixes were necessary beyond this. Both source PRs target master; this PR does too.

Note

Low Risk
Mapping-only change with no auth, custody, or swap execution logic; same pattern as other Rango chain additions.

Overview
Enables Rango DEX routing for the Sonic chain by wiring Sonic into the existing Rango network maps (previously null, so Sonic was excluded).

The source mapping scripts/mappings/rangoMappings.ts now maps Rango’s SONIC network to the Edge sonic plugin id; the generated src/mappings/rango.ts reflects sonic → SONIC for quote/swap requests. CHANGELOG records “(Rango) Sonic support” under Unreleased.

No new swap handlers or API logic in this diff—only chain enablement via mappings (consolidation PR; Sui from the related work was already on master).
