Description

Fixes the Velodrome/Tarot staking pools on Optimism that displayed USDC.e as USDC.

Two Tarot pools use the USDC.e contract (0x7F5c764cBc14f9669B88837ca1490cCa17c31607) but their token symbol was set to USDC:

• TAROT/USDC pool 0x3CD9F7912B6b04b702232FBb3f12F94145B8A0E4 (the reported case)
• USDC/VELO pool 0x5B0dce514B4AEd993751D2CF7379B75df9860312 (same mislabel)

Per edge-currency-accountbased/.../optimismInfo.ts, that contract is USDC.e, while native USDC is 0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85. Because both pools showed "USDC", a user holding native USDC (but no USDC.e) believed they could stake in both but could only stake in one. The staking logic correctly requires USDC.e (keyed by tokenId); only the label was wrong.

This relabels the two USDC.e token entries in optimismTarotPool.ts from USDC to USDC.e. Only the display symbol changes; tokenId, contract addresses, and the derived stakePolicyId are untouched, so on-chain behavior and existing staking positions are unaffected. The native-USDC pool keeps its USDC label. Also added the previously-missing return type on makePolicyConfig (flagged by lint on the touched file).

Verification: tsc --noEmit clean, full jest suite (511 tests) passes, and the value flow was traced end-to-end (symbol flows to stakeAssets[].currencyCode and the TarotPoolAdaptor token match, both staying consistent). An in-app screenshot of the corrected label could not be captured: the slot's debug build crash-loops at startup with a native Swift SQLite SIGTRAP in TransactionSQLDAO / Connection.prepare, reproduced across two test accounts and unrelated to this JS-only change. A reviewer with a working build should confirm the Optimism Tarot stake list now shows "TAROT + USDC.e".

Note

Low Risk
Display-only symbol changes in stake plugin config; token matching still uses unchanged tokenIds and contract addresses.

Overview
Corrects Optimism Tarot/Velodrome stake labels for two pools whose on-chain asset is bridged USDC (0x7F5c764c…): TAROT/USDC and USDC/VELO now show USDC.e instead of USDC, matching wallet/token naming so users see they need USDC.e, not native Optimism USDC.

tokenId, contract addresses, and stakePolicyId are unchanged—staking behavior and existing positions are unaffected. Also adds an explicit return type on makePolicyConfig and drops optimismTarotPool.ts from the ESLint ignore list; CHANGELOG updated.
