📝 Walkthrough

Walkthrough

This PR adds the Ink chain to multiple documentation tables and examples, and updates the contract-addresses component by adding an Ink explorer entry, introducing a typed ChainName, and adding an asArray helper to normalize explorer link inputs.

Changes

Cohort / File(s)	Summary
Contract Reference Docs docs/cow-protocol/reference/contracts/core/README.mdx, docs/cow-protocol/reference/contracts/periphery/README.mdx	Added "Ink" to explorerLinks / networks lists for various core and periphery contract entries (GPv2Settlement, GPv2AllowListAuthentication, GPv2VaultRelayer, HooksTrampoline, EthFlow entries); some network ordering adjusted.
Core Protocol Docs docs/cow-protocol/reference/core/auctions/rewards.md, docs/cow-protocol/reference/core/signing_schemes.mdx	Included Ink in rewards cap-supported chains and current rewards table; added Ink (and Polygon in one list) to domain separator explorerLinks and reorganized some network lists.
Tutorials & Local Test Docs docs/cow-protocol/tutorials/cow-swap/custom-links.md, docs/cow-protocol/tutorials/solvers/local_test.md	Added Ink WETH token entry to custom-links and added Ink staging/production orderbook endpoints to local_test.
Governance Docs docs/governance/token.md	Added an Ink entry to bridged token / vCOW tables (N/A where applicable).
Frontend: Contract Addresses Component src/components/contract-addresses/index.tsx	Added "Ink": "https://explorer.inkonchain.com" to explorerByChain; introduced exported ChainName = keyof typeof explorerByChain; changed explorerUrl and explorerLinks to accept ChainName typed params; added internal `asArray(arr: T

• #545: Refactors the same contract-addresses utilities (ChainName/asArray) and overlaps the explorer link typing changes.
• #558: Modifies explorerByChain mapping and adds new chain entries—closely related to the Ink explorer addition.
• #583: Adjusts explorer link behavior and chain entries in the contract-addresses component; may conflict or overlap with these changes.

Poem

🐇 Across the docs I hop and think,
I planted banners for the chain called Ink.
Explorer links now point the way,
Typed names hop in—hooray, hooray!
A little rabbit cheers the docs’ new bling. ✨

17-18: Network list ordering is inconsistent with other sections.

The EthFlow network arrays here are not alphabetically sorted, whereas the HooksTrampoline (line 45) and ComposableCoW (line 72) lists are. Consider reordering for consistency and easier maintenance (e.g., spotting missing or duplicate entries).

Suggested order

-| Production (most chains) | `0xbA3cB449bD2B4ADddBc894D8697F5170800EAdeC` | {explorerLinks(["Ethereum","Gnosis","Arbitrum One","Base","Avalanche","Polygon","BNB","Linea","Plasma","Ink","Sepolia"], "0xbA3cB449bD2B4ADddBc894D8697F5170800EAdeC")}, but not Lens! |

59-67: ⚠️ Potential issue | 🟡 Minor

Missing key prop on <Link> elements will cause React warnings.

When rendering an array of elements via reduce, each element needs a unique key prop to avoid React reconciliation warnings.

🔧 Proposed fix

   return chains.reduce(
     (acc, chain) => {
       if (acc.length) {
         acc.push(separator)
       }
-      acc.push(<Link to={explorerUrl(chain, address, { urlTrailing })}>{chain}</Link>)
+      acc.push(<Link key={chain} to={explorerUrl(chain, address, { urlTrailing })}>{chain}</Link>)
       return acc
     }
     , []);
 }

In `@docs/cow-protocol/reference/contracts/periphery/README.mdx`:
- Around line 45-56: The MDX array passed to explorerLinks is missing commas
after the "Ink" and "Optimism" entries which breaks parsing; update the array
inside the explorerLinks([...]) call (the list containing "Arbitrum One",
"Avalanche", ..., "Ink", "Lens", "Linea", "Optimism", "Plasma") to include the
missing commas so each string is a separate element and the MDX/JS is valid.

In `@docs/cow-protocol/reference/core/auctions/rewards.md`:
- Line 100: Replace the incorrect token symbol in the Ink reward line: change
the expression "Ink: $$\min\{X.X ~\textrm{XPL}, 6 ~\textrm{COW}\}$$." so that
the placeholder token symbol "XPL" is "ETH" (e.g., "Ink: $$\min\{X.X
~\textrm{ETH}, 6 ~\textrm{COW}\}$$."), preserving the LaTeX formatting and the
rest of the text.

70-72: Consider moving the asArray helper above explorerLinks for better readability.

While function hoisting makes this work, placing helper functions before their usage improves code flow and readability.
